专利说明:

[0001] [0001] The present invention relates to hair treatment compositions in which the addition of certain anionic polymers, in combination with one or more cationic polymers, has been found to provide an unexpected increase in the formation of coacervates, as well as deposition benefits. BACKGROUND OF THE INVENTION
[0002] [0002] For years, anti-dandruff shampoos have been widely used to treat dandruff and the cleansing of hair and scalp, but there remains a need for optimized anti-dandruff shampoos. In general, dandruff shampoos are formulated with dandruff agents in combination with surfactants and aqueous systems that are intended to deposit the dandruff agents on the scalp. Anti-dandruff agents can be insoluble particles such as zinc pyrithione and / or surfactant-soluble substances, such as climbazole or octopirox. Many dandruff shampoos use cationic polymers with anionic surfactants to form coacervates that aid in the deposition of insoluble particulate agents. However, in general, coacervates do not affect the deposition of soluble agents, since soluble agents are not associated with coacervates formed between cationic polymers and anionic surfactants. In fact, it can be difficult to deposit on the scalp much more than 1 to 2% of the soluble agents present in anti-dandruff shampoos while the remaining 98 to 99% of the soluble agents in the formulas are rinsed. Since many of the anti-dandruff agents can be relatively expensive, allowing> 97% of the soluble agents to be rinsed, is equivalent to throwing money away, and thus there is a need for a shampoo that can more efficiently deposit soluble anti-dandruff agents. In addition, as consumers continue to desire a shampoo that offers superior dandruff efficacy and less deposition of the dandruff agent results in lower dandruff efficacy, there remains a need for a shampoo that can deposit a higher percentage of soluble agents present on the scalp. in dandruff shampoos.
[0003] [0003] The association of several classes of surfactants in micellar aggregates is a well-known phenomenon. Micelles are often designed as static spherical aggregates, but in reality, micelles are in dynamic equilibrium with individual surfactant molecules (monomers) that are constantly being exchanged between the volume and the micelles. In addition, the micelles themselves are continually disintegrating and reassembling. There are two relaxation processes involved in micellar solutions. The first is a rapid relaxation process called 1, which is associated with the rapid exchange of monomers between micelles and the surrounding mass phase. The second relaxation time, Tt ,, is attributed to the micelle formation and the dissolution process (that is, the micelle lifetime). The extensive experimental research on the micellization kinetics of Shah and collaborators (Patist, A., Jha, B.K., Oh, S.G., and Shah, D.O., <>. Surfactants Deterg. 2, 317, 1999); James-Smith, M.A., Shekhawat, D., and Shah, D.O., Tenside Surf. Det. 44, (2007) 142) showed a strong correlation of T7 with various detergency properties including oil solubilization in micellar solutions and droplet size in emulsions, as well as surfactant properties such as dynamic surface tension and micelle stability.
[0004] [0004] It has been surprisingly “discovered that the addition of certain anionic polymers in combination with one or more cationic polymers provides an unexpected increase in the formation of coacervates, as well as a deposition benefit. SUMMARY OF THE INVENTION

[0054] [0054] The hair treatment composition may comprise a cationic guar gum polymer, which is a cationically substituted galactomannan gum (guar) derivative. Guar gum for use in the preparation of these guar gum derivatives is typically obtained as a naturally occurring material from the seeds of the guar plant. The guar gum molecule itself is a straight-chain mannan, which is branched at regular intervals with single-membered galactose units into alternative mannose units. The mannose units are linked to each other by means of glycosidic B (1-4) bonds. Galactose branching occurs through a (1-6) link. The cationic derivatives of guar gums are obtained through the reaction between the hydroxyl groups of polygalactomannan and reactive quaternary ammonium compounds. The degree of substitution of the cationic groups on the guar gum structure needs to be sufficient to provide the necessary cationic charge density described above.

[0056] [0056] The cationic guar gum polymer may have an average molecular weight less than about 1.5 million g / mol and has a charge density of about 0.1 m / g to about 2.5 meq / g . The cationic guar gum polymer can have an average molecular weight of less than 900 thousand g / mol or from about 150 thousand to about 800 thousand g / mol or from about 200 thousand to about 700 thousand g / mol or about 300,000 to about 700,000 g / mol or about 400,000 to about 600,000 g / mol, from about 150,000 to about 800,000 g / mol or from about 200,000 to about 700 thousand g / mol or from about 300 thousand to about 700 thousand g / mol or from about 400 thousand to about 600 thousand g / mol. The cationic guar gum polymer can have a charge density of about 0.2 to about 2.2 meg / g or about 0.3 to about 2.0 meq / g or about 0.4 at about 1.8 meq / g; or from about 0.5 meq / g to about 1.5 megq / g.
[0057] [0057] The cationic guar gum polymer can be formed from quaternary ammonium compounds. The quaternary ammonium compounds for the formation of the guar cationic polymer are adapted to the general formula 1: R5 1 Re N R &> R: where R , Rº and Rº are methyl or ethyl groups; Rº is or an epoxy alkyl group with the following general formula 2: HC CH-Rr— E / o or Rº is a halohydrin group with the general formula 3: XxX Pxqn "RT— oH where D is a C, a C alkylene; X is chlorine or bromine and Z2 is an anion such as Cl-, Br-, I- or HSO, 4-.

[0059] [0059] Other suitable cationic guar gum polymers include derivatives of cationic guar gum, such as hydroxy propyl triammonium gum chloride. The cationic guar gum polymer may be a hydroxy propyl triamonium chloride.

[0061] [0061] The hair treatment compositions of the present invention may comprise a galactomannan polymer derivative with a ratio between mannose and galactose greater than 2: 1 on a monomer to monomer basis; the galactomannan polymer derivative selected from the group consisting of a cationic galactomannan polymer derivative and an amphoteric galactomannan polymer derivative with a positive net charge. For use in the present invention, the term "cationic galactomannan" refers to a polymer of galactomannan to which a cationic group is added. The term "amphoteric galactomannan" refers to a galactomannan polymer to which a cationic group and an anionic group are added, so that the polymer has a net positive charge.
[0062] [0062] Galactomannan polymers are present in the seed endosperm of the Legume family. Galactomannan polymers are created from a combination of mannose monomers and galactose monomers. The galactomannan molecule is a straight chain branched mannan at regular intervals with single-membered galactose units in specific mannose units. The mannose units are linked to each other by means of glycosidic B (1-4) bonds. Galactose branching occurs through a link to (1-6). The ratio between mannose monomers and galactose monomers varies according to the species of the plant, and is also affected by the climate. The non-guar galactomannan polymer derivatives of the present invention have a ratio of mannose to galactose greater than 2: 1 on a monomer to monomer basis. Suitable ratios between mannose and galactose can be greater than about 3: 1 and the ratio between mannose and galactose can be greater than about 4: 1. Analysis of the ratios between mannose and galactose is well known in the art and is typically based on the measurement of galactose content.
[0063] [0063] Gum for use in preparing non-guar galactomannan polymer derivatives is typically obtained in the form of a naturally occurring material, such as seeds or grains from plants. Examples of various non-guar galactomannan polymers include, but are not limited to, gum tare (3 parts mannose / l part galactose), locust bean or locust bean (4 parts mannose / 1 part galactose) and cassia gum (5 parts of mannose / 1 part of galactose).
[0064] [0064] Non-guar galactomannan polymer derivatives can have a molecular weight of about 1,000 to about 10,000,000 and / or from about 5,000 to about
[0065] [0065] The hair treatment compositions of the invention may also include galactomannan polymer derivatives with a cationic charge density of about 0.5 meq / g to about 7 megq / g. Galactomannan polymer derivatives can have a cationic charge density of about 1 m / g to about 5 megq / g. The degree of substitution of the cationic groups on the structure of the galactomannan needs to be sufficient to provide the cationic charge density described above.
[0066] [0066] The galactomannan polymer derivative can be a cationic derivative of the non-guar galactomannan polymer, which is obtained by the reaction between the hydroxyl groups of the polygalactomannan polymer and the reactive quaternary ammonium compounds. Quaternary ammonium compounds suitable for use in the formation of cationic galactomannan polymer derivatives include those according to general formulas 1 to 5, as defined above.
[0067] [0067] Non-guar cationic galactomannan polymer derivatives formed from the reagents described above are represented by the general formula 6: R
[0068] [0068] Alternatively, the galactomannan polymer derivative may be an amphoteric galactomannan polymer derivative having a net positive charge, obtained when the cationic galactomannan polymer derivative further comprises an anionic group.
[0069] [0069] Non-cationic galactomannan may have a ratio between mannose and galactose greater than about 4: 1, a molecular weight of about 1,000 g / mol to about
[0070] [0070] Compositions for treating hair may comprise cationically modified water-soluble starch polymers. For use in the present invention, the term "cationically modified starch" refers to a starch to which a cationic group is added prior to the degradation of the starch to a lower molecular weight, or to a cationic group is added after the modification of the starch to to obtain a desired molecular weight. The definition of the term "cationically modified starch" also covers amphoterically modified starches. the term "amphoterically modified starch" refers to a hydrolyzed starch to which a cationic group and an anionic group are added.
[0071] [0071] The cationically modified starch polymers shown in the present invention have a percentage of bound nitrogen from about 0.5% to about 4%.
[0072] [0072] Cationically modified starch polymers for use in hair care compositions can have a molecular weight of about
[0073] [0073] Compositions for hair treatment may include cationically modified starch polymers that have a charge density of about 0.2 megq / g to about 5 meq / g / or about 0.2 meq / g to about 2 meq / g. Chemical modification to obtain such a charge density includes, but is not limited to, the addition of amino groups and / or ammonium groups to the starch molecules. Some non-limiting examples of these ammonium groups may include substituents such as trimethyl hydroxy propyl chloride, trimethyl hydroxy propyl ammonium chloride, dimethyl stearyl hydroxy propyl ammonium chloride and dimethyl dodecyl hydroxy propyl ammonium chloride. See Solarek, DB, Cationic Starches in Modified Starches: Properties and Uses, Wurzburg, OB, Ed., CRC Press, Inc., Boca Raton, Florida, USA, 1986, pages 113 to 125. Cationic groups can be added to starch prior to degradation to a lower molecular weight or can be added after such modification.
[0074] [0074] Cationically modified starch polymers generally have a degree of substitution of a cationic group of about 0.2 to about 2.5. For use in the present invention, the "degree of substitution" of cationically modified starch polymers is the average of the number of hydroxyl groups in each anhydroglycosis unit that is derivatized by substituent groups. Since each anhydroglycosis unit has three groups - hydroxyl potentially available for substitution, the maximum possible degree of substitution is 3. The degree of substitution is expressed as the number of moles of substituting groups per mole of anhydroglycosis units, on average molar. The degree of substitution can be determined using proton nuclear magnetic resonance spectroscopy (".sup.lH NMR") methods well known in the art. Suitable techniques of.sup.l1H NMR include those described in "Observation on NMR Spectra of Starches in Dimethyl Sulfoxide, Iodine-Complexing, and Solvating in Water- Dimethyl Sulfoxide", Qin-Ji Peng and Arthur S. Perlin, Carbohydrate Research, 160 (1987), 57-72; and "An Approach to the Structural Analysis of Oligosaccharides by NMR Spectroscopy", J. Howard Bradbury and J. Grant Collins, Carbohydrate Research, 71, (1979), 15-25.
[0075] [0075] The source of starch before chemical modification can be chosen from a variety, such as tubers, vegetables, cereals and grains. Some non-limiting examples of these sources may include corn starch,
[0076] [0076] Cationically modified starch polymers can be selected from degraded cationic corn starch, cationic tapioca, cationic potato starch and mixtures thereof. Alternatively, the cationically modified starch polymers are cationic corn starch and cationic tapioca.
[0077] [0077] Starch, before degradation or after modification to a lower molecular weight, may comprise one or more additional modifications. For example, these modifications can include crosslinking, stabilization reactions, phosphorylations and hydrolysations. Stabilization reactions can include alkylation and esterification.
[0078] [0078] Cationically modified starch polymers can be incorporated into the composition in the form of hydrolyzed starch (for example, acid, enzyme, or alkaline degradation), oxidized starch (for example, peroxide, peracid, hypochlorite, alkaline, or any other oxidizing agent), physically or mechanically degraded starch (for example, through the input of thermomechanical energy from the processing equipment), or combinations thereof.
[0079] [0079] An optimal form of starch is one that is readily soluble in water, and forms a substantially clear solution (% transmittance of about 80 to 600 nm) in water. The transparency of the composition is measured by ultraviolet / visible spectrophotometry (UV / VIS), which determines the absorption or transmission of UV / VIS light by a sample, using a Gretag Macbeth Color i 5 colorimeter, according to the related instructions. A wavelength of light of 600 nm proved to be adequate to characterize the degree of clarity of cosmetic compositions.
[0080] [0080] Cationically modified starch suitable for use in hair treatment compositions is available from known starch suppliers. Also suitable for use in hair treatment compositions is modified nonionic starch which can be further derivatized into a cationically modified starch as is known in the art. Other suitable modified starch-based starting materials can be quaternized, as is known in the art, to produce the cationically modified starch polymer suitable for use in hair treatment compositions.
[0081] [0081] Starch Degradation Procedure: an aqueous starch paste can be prepared by mixing granular starch in water. The temperature is raised to around 35ºC. An aqueous solution of potassium permanganate is then added to a concentration of about 50 ppm, based on the amount of starch. The pH is raised to about 11.5 with sodium hydroxide, and the aqueous slurry is stirred enough to avoid decanting the starch. Then a solution of hydrogen peroxide diluted to about 30% in water is added to a content of about 1% peroxide, based on the amount of starch. The pH of about 11.5 is then restored by adding additional sodium hydroxide. The reaction is complete after a period of about 1 to about 20 hours. The mixture is then neutralized with dilute hydrochloric acid. The degraded starch is recovered by filtration followed by washing and drying.

[0112] [0112] The cationic polymer described in the present invention, can assist in providing damaged hair, particularly chemically treated hair, a substitute hydrophobic F layer. The microscopically thin layer F provides natural resistance to climate action, while helping to retain moisture and prevent further damage. Chemical-based treatments damage the hair cuticle and remove its protective F layer. As layer F is removed, the hair becomes more and more hydrophilic. It has been found that when lyotropic liquid crystals are applied to chemically treated hair, the hair becomes more hydrophobic and younger, both in appearance and touch. Without sticking to any particular theory, it is believed that the complex of lyotropic liquid crystals creates a hydrophobic layer or film that coats the hair fibers protecting it, much like the natural F layer does. The hydrophobic layer restores the hair to a generally new and healthier looking state. Lyotropic liquid crystals are formed by the combination of polymers - “synthetic cationics described here with the anionic detersive surfactant component mentioned above in the hair treatment composition. The synthetic cationic polymer has a relatively high charge density. It should be noted that some synthetic polymers that have a relatively high cationic charge density do not form liotropic liquid crystals, mainly due to their abnormal linear charge densities.

[0141] [0141] In the present invention, a gel network can be present. The gel mesh component of the present invention can comprise at least one fatty amphiphile. For use in the present invention, "fatty amphiphile" refers to a compound that has a hydrophobic tail group as defined as an alkyl, alkenyl group (containing up to 3 double bonds), aromatic alkyl or branched alkyl of length C ;, to Cx and a hydrophilic head group that does not make the compound soluble in water, the compound also having a neutral net at the pH of the shampoo composition.
[0142] [0142] The shampoo compositions of the present invention comprise fatty amphiphile as part of the preformed dispersed gel mesh phase, in an amount of about 0.05% to about 14%, preferably about 0.5 % to about 10% and, more preferably, from about 1% to about 8%, by weight of the shampoo composition.
[0143] [0143] According to the present invention, suitable OoOS fatty amphiphiles, or suitable mixtures of two or more fatty amphiphiles, have a melting point of at least about 27 ° C. The melting point of the surfactants used in accordance with the present invention can be measured by a standard melting point method, as described in US Pharmacopeia, USP-NF, General Chapter <741> "Melting range or temperature". The melting point of a mixture of two or more materials is determined by mixing two or more materials at a temperature above the respective melting points and then allowing the mixture to cool. If the resulting composite is a homogeneous solid below about 27 ° C, then the mixture has a melting point suitable for use in the present invention. A mixture of two or more fatty amphiphiles, in which the mixture comprises at least one fatty amphiphile with an individual melting point below about 27 ° C, is still suitable for use in the present invention as long as the composite melting point of the mixture is at least about 27ºC.

[0145] [0145] In the present invention, the shampoo composition may comprise fatty alcohol gel networks. These gel networks are formed by the combination of fatty alcohols and surfactants in the ratio of about 1: 1 to about 40:11, about 2: 1 to about 20: 1 and / or about 3: 1 to about 10: 1. The formation of a gel network involves heating a dispersion of the fatty alcohol in water with the surfactant to a temperature above the melting point of the fatty alcohol. During the mixing process, fatty alcohol melts, allowing the surfactant to be partitioned into fatty alcohol droplets. The surfactant carries water with it into the fatty alcohol. This turns drops of isotropic fatty alcohol into drops in liquid crystalline phase. When the mixture is cooled below the melting temperature of the chain, the liquid crystalline phase is converted into a solid crystalline gel network. The gel network contributes a stabilizing benefit to cosmetic creams and hair conditioners. In addition, it provides the benefits of conditioning sensation for hair conditioners.
[0146] [0146] Fatty alcohol can be included in the fatty alcohol gel network at a content, by weight, of about 0.05% by weight to about 14% by weight.

After cooling, the fatty alcohols and the surfactant are crystallized to form a crystalline gel network.

[0163] [0163] The average molecular weight of the insoluble polysiloxane, the viscosity of the internal phase of the insoluble polysiloxane, the viscosity of the silicone emulsion and the particle size comprising the insoluble polysiloxane are determined by the methods commonly used by those skilled in the art, such as the methods of present invention presented in Smith, AL The Analytical Chemistry of Silicones, John Wiley & Sons, Inc .: New York, 1991. For example, the viscosity of the silicone emulsion can be measured at 30ºC with a Brookfield viscometer with a 6 to 2 spindle, 5 rpm.

When related to chelators, the term "salts and derivatives thereof" means salts and derivatives that comprise the same functional structure (for example, the same chemical structure) as the chelator to which they refer and that have similar or better chelating properties. This term includes alkali metal, alkaline earth salts, ammonium, substituted ammonium (ie, monoethanol ammonium, diethanol ammonium, triethanol ammonium), chelating esters with an acid portion and mixtures thereof, in particular, all sodium salts , potassium or ammonium.

[0177] [0177] The hair treatment compositions of the present invention can be presented in typical hair treatment formulations. They can be in the form of solutions, dispersion, emulsions, powders, talc, encapsulated, spheres, sponges, solid dosage forms, foams and other application mechanisms. The compositions of the present invention can be hair tonics, hair products without rinsing, such as products for treatment and styling, hair products with rinsing, such as shampoos and personal care products and treatment products; and any other form that can be applied to the hair. IT. APPLICATOR
[0178] [0178] In the present invention, the composition for hair treatment can be dispensed from an applicator for dispensing directly on the scalp area. The direct dispensing on the scalp, through a targeted application of an applicator, allows the deposition of undiluted cleaning agents directly where cleaning needs are greatest. This also minimizes the risk of eye contact with the cleaning solution.
[0179] [0179] The applicator is attached or can be attached to a bottle containing the cleaning composition for hair treatment. The applicator can consist of a base that retains or extends to a single tip or a plurality of tips. The tips have openings that can be located at the end, or at any point between the end and the base. These openings allow the product to be distributed from the bottle directly over the hair and / or scalp.
[0180] [0180] Alternatively, the applicator can also consist of fixed or brush-shaped bristles or extending from a base. In this case, the product can be dispensed from the base and the bristles can allow the product to be distributed through the combing or brushing movement.
[0181] [0181] The applicator and tip design and materials can also be optimized to allow scalp massage. In this case, it may be beneficial for the geometry of the tip or the bristles at the ends to be more rounded similar to the sphere applicator used for eye creams. It may also be beneficial for the materials to be smoother and smoother; for example, metal or metal-like finishes, "rubbery materials".
[0182] [0182] Shampoo viscosities can be measured in a 2.5 ml sample using a Brookfield RS cone and plate rheometer with C75 cone at 1 to 2 s' at 27ºC for 3 min.
[0183] [0183] In the present invention, the surfactant composition alone with the surfactant-soluble anti-dandruff agent has a viscosity of less than about 5,000 cps at 2s and cannot be thickened above
[0184] [0184] Techniques for analyzing the formation of complex coacervates are known in the art. One method for evaluating the formation of coacervates by diluting a transparent or translucent composition involves using a spectrophotometer to measure the percentage of light transmitted through the diluted sample ($ T). As the percent light transmittance values (% T) measured in the dilution decrease, higher levels of coacervates are typically formed. Dilution samples can be prepared in various weight ratios between water and composition, for example, 2 parts of water for 1 part of composition (2: 1), or 7.5 parts of water for 1 part of composition (7.5: 1 ), or 16 parts of water for 1 part of composition (16: 1), or 34 parts of water for 1 part of composition (34: 1), and the% T measured for each sample of dilution ratio. Examples of possible dilution ratios may include 2: 1, 3: 1, 5: 1, 7.5: 1, 11: 1, 16: 1, 24: 1 or 34: 1. By averaging the% T values for samples that span a range of dilution ratios, it is possible to simulate and determine how many coacervates a composition would average as a consumer applies the composition to damp hair, generates foam and then rinses them. . The average% T can be calculated by taking the numerical average of individual% T measurements for the following dilution ratios: 2: 1, 3: 1, 5: 1, 7.5: 1, 11: 1, 16: 1, 24: 1, and 34: 1.
[0185] [0185] ST can be measured using ultraviolet / visible spectrophotometry (UV / VIS), which determines the transmission of UV / VIS light through a sample. A wavelength of light of 600 nm was shown to be adequate to characterize the degree of light transmittance through a sample. Typically, it is best to follow the specific instructions related to the specific spectrophotometer being used. In general, the procedure for measuring percentage transmittance begins by adjusting the spectrophotometer to 600 nm. Then, a "standard sample" is measured for calibration, in order to calibrate the reading to 100 percent transmittance. A single test sample is then placed in a cuvette designed to fit the specific spectrophotometer, taking care to ensure that no air bubbles are in the sample before% T is measured by the spectrophotometer at 600 nm. Alternatively, multiple samples can be measured simultaneously using a spectrophotometer, for example, the SpectraMax M-5 available from Molecular Devices. Multiple dilution samples can be prepared inside a 96-well plate (VWR catalog No. 82006-448) and then transferred to a visible 96-well flat bottom plate (Greiner item No. 655-001), ensuring that no air bubbles remain inside the sample. The flat bottom plate is placed inside the SpectraMax M-5 and% T is measured using Software Pro v.5TM available from Molecular Devices.
[0186] [0186] The deposition of the anti-dandruff agent soluble in surfactant, for example, Octopirox, in vivo on the scalp can be determined by ethanol extraction of the agent after the scalp has been treated with a cleaning composition containing soluble agent in surfactant and rinsed. The concentration of agent in the solvent or extraction solution is measured by HPLC. Quantification is done by reference to a standard curve. The concentration detected by HPLC is converted to a quantity collected using the concentration in grams multiplied by volume.
[0187] [0187] The percentage of agent deposited can be calculated using the following equation:% agent deposited grams of agent deposited - scalp area extracted = (Weight of agent in shampoo) x (grams of shampoo applied) * 10º * area of treated scalp
[0188] [0188] Deposition efficiency can be calculated using the following equation: Deposition efficiency% of agent deposited using the example formula -% of agent deposited using the control formula
[0189] [0189] Calculation of the sample by% of depositive pyroctone olamine, where: Grades of deposited agent = 1.8x10-ºg Extracted scalp area = 1 cm % by weight of pyroctone olamine in shampoo = 1.0% Grams of shampoo applied = 5 g Treated scalp area = 300 cm
[0190] [0190] Calculation sample for deposition efficiency, where:% of pyrochthon olamine deposited by the example formula = 9.30%% of pyrochthon olamine deposited by the control formula = 1.08% Deposition efficiency = 250 1.08 % Efficiency of deposition = 8.6X Preparation of Shampoo Compositions
[0191] [0191] Shampoo compositions are prepared by adding surfactants, anti-dandruff agents, perfumes, viscosity modifiers, cationic polymers, and the rest of the water with wide agitation to ensure a homogeneous mixture. The mixture can be heated to 50 to 75ºC to accelerate the solubilization of the soluble agents, then cooled. The pH of the product can be adjusted as necessary to obtain shampoo compositions of the present invention that are suitable for application to human hair and scalp, and can vary from about pH 4 to 9 or from about pH 4 to 6 , or about pH 4 to 5.5, or about pH 4 to 5, based on the selection of specific detersive surfactants and / or other components.
[0192] [0192] The compositions illustrated in the Examples below are prepared using conventional formulation and mixing methods. All exemplified amounts are mentioned as weight percent on an active basis and exclude minor materials such as diluents, preservatives, colored solutions, imaging ingredient, botanical products and so on, unless otherwise specified. All percentages are based on weight, unless otherwise specified.
[0193] [0193] Sulfate sodium lauret sulfate (SLE1S) is a surfactant that forms more stable micelles and as such forms of elongated micelles and shows an increase in viscosity after the addition of sodium chloride. This increase in viscosity for SLEIS after the addition of sodium chloride is demonstrated in Example 1.
[0195] [0195] A comparison of Examples 3 and 4 shows that Example 4, which contains sodium undecyl sulphate that forms less stable micelles, deposits pyroctone olamine with 1.7X of deposition efficiency of Example 3, which contains lauret sulfate -l sodium which forms more stable micelles.
[0196] [0196] Examples 5 to 7 are additional examples of surfactant combinations that form less stable micelles and cannot be thickened with the addition of sodium chloride. Examples 8 to 10 show that when surfactants that form less stable micelles are combined with a surfactant (SLEIS) that form more stable micelles, these compositions cannot yet be thickened to a viscosity greater than about 2000 cps with sodium chloride.
[0197] [0197] Examples 12 through 14 show that when surfactants that form less stable micelles are combined with a surfactant (SLEIS) that form stable micelles and are also combined with cotensants (CAPB and CMEA) that typically increase viscosity, these mixtures cannot yet be thickened with sodium chloride at a viscosity greater than 2000 cps.

[0198] [0198] A method for evaluating the formation of coacervates by diluting a transparent or translucent composition is intended to measure the percentage of light transmitted through the diluted sample. By measuring the percentage of light transmittance (% T) of samples that cover a range of dilution ratios between water and composition and then averaging these% T values, it is possible to simulate and determine how many coacervates a composition it would form on average as a consumer applies that composition to damp hair, generates foam and then rinses them. The more coacervates are formed, the less light is transmitted through the diluted sample and the lower the% T value.
[0199] [0199] 0 Example 15 contains surfactants that form more stable micelles and, therefore, when combined with a cationic polymer such as guar hydroxypropyltriammonium chloride, forms a typical amount of coacervates upon dilution as seen in the average% T of 59%. Example 16 contains a combination of surfactant that forms less stable micelles, so that when combined with guar hydroxypropyltriammonium chloride alone, this composition forms a smaller amount of coacervates upon dilution as seen in the average% T of 70%. Example 17 is an embodiment of the present invention and contains a combination of surfactant that forms less stable micelles in combination with both an anionic polymer (acrylate copolymer) and a cationic polymer (guar hydroxypropyltriamonium chloride). The composition of Example 17, upon dilution, demonstrates a surprising increase in the formation of coacervates as seen by the reduction in the average% T from 70% in Example 16 to 44% in Example 17.
