Stable Aqueous Surfactant Composition {STABLE AQUEOUS SURFACTANT COMPOSITIONS}
[2] Conventionally, various substantially insoluble compounds could not be adequately stabilized in aqueous surfactant containing compositions. For example, various aqueous surfactant compositions containing silicone additives therein, such as, for example, hair or skin conditioners, have been separated and / or creamed from their surfactant bases. Various gloss materials commonly used to form a glossy appearance have a short shelf life, form a reduced glossy appearance (“glossy appearance”), or virtually precipitate. In other words, the problem of instability has generally arisen when incorporating silicone and shiny materials.
[3] Although cationic dyes or basic dyes for hair have been used in shampoos to impart a temporary color or highlight, cationic dyes are generally not very well compatible with the anionic surfactants commonly used in formulations of conventional shampoos. Thus, although amphoteric surfactants have been used to impart detergency and detergent properties to shampoos, these amphoteric surfactants do not have sufficient thickening to provide the desired flowability of the product. Conventional polymerizable rheology modifiers such as carbomer and / or acrylate / C _10-30 alkylacrylate crosspolymers have been used to increase the viscosity, but the rheological stability of such compositions is still generally poor.
[4] Various efforts have been made to improve the above problems.
[5] For example, US Pat. No. 5,656,257 relates to anionic shampoos and conditioning compositions comprising oily conditioning agents, shampoos, acrylate copolymers, cationic conditioning agents and water. It also relates to the incorporation of C ₈ -C ₁₈ fatty acids. The composition uses both anionic acrylate copolymers, oily conditioning agents and cationic conditioning agents to maintain stability and dispersibility.
[6] WO 99/21530 discloses at least one surfactant selected from the group consisting of anionic, nonionic, cationic and zwitterionic surfactants and mixtures thereof from about 1.00% to about 80.00% by weight; From about 0.05% to about 15.00% by weight of from 10 to about 30 carbon atoms of at least one fatty alcohol; About 0.10% to about 15.00% nonvolatile silicone; And from about 1.35% to about 2.70% by weight of the uncrosslinked polymerizable suspending agent.
[7] EPO 463,780 is an insoluble, nonvolatile, which can be obtained by including a polymer suspended to prevent "creaming" of silicon on top of the bottle during storage, and to prevent precipitation of mica coated with titanium dioxide particles. A stable and shiny shampoo composition comprising silicone. The composition also relates to an aqueous sampu composition comprising the following components in addition to water:
[8] (a) 2 to 40 weight percent of a surfactant selected from anionic, nonionic or amphoteric surfactants or mixtures thereof;
[9] (b) 0.01 to 10% by weight of insoluble, nonvolatile silicone;
[10] (c) 0.1 to 5% by weight of polyacrylic acid, crosslinked polymer of acrylic acid, copolymer of acrylic acid and hydrophobic monomer, copolymer of carboxylic acid containing monomer and acrylic ester, crosslinked copolymer of acrylic acid and acrylate ester, and Suspended polymers selected from heteropolysaccharide gums; And
[11] (d) 0.01-5% by weight of mica coated with titanium dioxide.
[12] U. S. Patent No. 4,529, 773 relates to a composition containing an associative thickener (alkali soluble emulsion polymer modified to be hydrophobic) which has been acidified in the presence of a surfactant after neutralization and activation to a pH above 6.5.
[13] However, the prior art does not yield sufficiently stabilized aqueous surfactant compositions such as various silicones, oily materials, gloss materials, dyes for cationic hair and other materials that are substantially insoluble.
[1] The present invention is a substantially crosslinked alkali swellable acrylate copolymer rheology modifier, surfactant, alkaline material, and various compounds, such as substantially insoluble materials such as silicones, oily materials, or gloss materials that require suspension and stabilization. It relates to a stable aqueous composition containing therein. The present invention also relates to the preparation of rheologically phase stable cationic hair dye compositions. The invention also relates to the incorporation of an acidic substance after the addition of an alkaline substance in order to reduce the pH of the composition without adversely affecting the viscosity and flowability of the composition.

[14] Stable aqueous compositions include substantially crosslinked alkali swellable acrylate copolymer flow modifiers, water, alkaline materials and effective amounts of surfactants to allow stabilized or suspended compounds in the composition that are substantially insoluble. Compositions containing various volatile and nonvolatile silicone oils, oily materials and the like can be stabilized. Compositions containing a glossy material may also be stabilized and may further provide a glossy appearance to the composition. In addition, compositions containing cationic dyes can also be obtained, and allowable fluidity can be maintained by this cationic dye. In addition, "back-acid" formulation techniques can be used to obtain low pH compositions. Such stable aqueous surfactant compositions are generally gentle and do not form separation, precipitation or creaming over extended periods of time, such as for more than a month at 45 ° C., without significantly increasing or decreasing the viscosity or pH. It is possible to maintain acceptable fluidity. The polymerizable rheology modifier generally consists of one or more carboxylic acid monomers, vinyl monomers and polyunsaturated monomers. The surfactant may be an anionic, amphoteric, zwitterionic, nonionic or cationic surfactant, or a combination thereof.
[15] The introduction provided herein is for illustrative purposes and is not intended to limit the invention in any way.
[16] Polymerizable Flow Modifiers
[17] Polymeric rheology modifiers provide a variety of rheological properties such as flowability, thickening or viscosity, vertical cling, suspension and yield value. In the present application, yield stress (also referred to as "yield stress") is defined as the initial resistance to flow under stressed environments. This yield stress can be measured using a number of techniques, such as using a constant stress rheometer or extrapolation using a Brookfield viscometer. The usefulness obtained by measuring this technique and yield stress is described by The B.F. Further described in Technical Data Sheet No. 244 available from Goodrich Company. The polymers are also useful for stabilizing formulated insoluble materials such as particulate or oily materials, as well as providing stability to the overall formulation.
[18] Substantially crosslinked alkali swellable acrylate copolymer rheology modifiers of the present invention may generally be prepared through various polymerization routes such as emulsification, dissolution, precipitation, and the like, of which emulsion polymerization is generally preferred. Emulsion polymerization is generally carried out at a pH of about 2.5 to about 5.0 with at least three substantially ethylenically unsaturated components. In addition, none of these monomers is an associative monomer which is a copolymerizable surfactant capable of non-specific hydrophobic association, as with conventional surfactants.
[19] Polymeric rheology modifiers of the present invention generally comprise three structural components. The first component is at least one carboxylic acid monomer having from about 3 to about 10 carbon atoms. Examples of such monomers include, but are not limited to, acrylic acid, methacrylic acid, itaconic acid, fumaric acid, crotonic acid, maleic acid or aconic acid. Moreover, especially when used in small amounts together with acrylic acid or methacrylic acid, half esters of C _1-4 alkanol and polyacids such as maleic acid, fumaric acid, itaconic acid or aconic acid may be used in combination.

[27] X is CH ₃ , Y is -COOR, -C ₆ H ₄ R ', -CN or -CH = CH ₂ , or
[28] X is Cl, Y is Cl,
[29] R is C _1-18 alkyl or hydroxy C _2-18 alkyl, R ′ is H or C _1-18 alkyl,
[30] R ¹ is C _1-18 alkyl)

[32] The third component that forms the acrylate rheology modifier is one or more polyunsaturated compounds. Monomerically unsaturated compounds containing a reactor capable of crosslinking the copolymer formed before the polymerization, during the polymerization and after the polymerization may be used.
[33] Various polyunsaturated compounds are used to form partially or nearly crosslinked three-dimensional networks. Examples of such polyunsaturated compounds include polyalkenyl ethers or polyalcohols of sucrose; Diallylphthalate, divinyl benzene, allyl (meth) acrylate, ethylene glycol di (meth) acrylate, methylene bisacrylamide, trimethylolpropane, tri (meth) acrylate, diallyl itaconate, diallyl fumarate Castor oils or derivatives of polyols consisting of diallyl maleate, zinc (meth) acrylates, ethylenically unsaturated carboxylic acids and the like, glycidyl methacrylate, N-methylol acrylamide or N -Alkoxymethylacrylamide, alkoxy to be C ₁ -C ₁₈ alcohol; There is a caprolactone end-protected with hydroxy (meth) acrylate or (meth) acrylate.
[34] Those skilled in the art of preparing unsaturated derivatives, together with ethylene oxide or propylene oxide or combinations thereof, consist of unsaturated acids such as acrylic acid, methacrylic acid, or unsaturated anhydrides such as maleic anhydride, citraconic anhydride and itaconic anhydride. Schemes such as esterification of polyols or addition reactions with unsaturated isocyanates such as 3-isopropenyl-α-α-dimethylbenzene isocyanate are also within the scope of the present invention. Where "(meta)" is used it means that the methyl group is used arbitrarily.
[35] The third component is about 0.01% to about 5% by weight, preferably about 0.03% to about 3% by weight, more preferably based on the total weight of the entire monomer forming the acrylate copolymer rheology modifier. Is used in an amount of about 0.05% to about 1% by weight.
[36] In addition, the crosslinked copolymer rheology modifier is generally free of any moieties derived from associative monomers (ie, copolymerizable surfactants). In general, "not present" is defined as containing less than about 1 weight percent, preferably less than about 0.5 weight percent, more preferably less than about 0.2 weight percent.
[37] Partially or nearly crosslinked three-dimensional networks of the present invention may be prepared by any conventional method, such as described in US Pat. No. 4,138,380 or US Pat. No. 4,110,291, which is incorporated herein by reference. Generally, at least one monomer of the carboxylic acid monomer, vinyl monomer and polyunsaturated monomer is added to the reaction vessel containing water therein. Appropriate amounts of conventional or common emulsion polymerization surfactants, such as sodium lauryl sulfate, are added together with initiators of the emulsion type, such as, for example, sodium persulfate or potassium persulfate, redox initiators and the like. The reaction vessel may contain a chain transfer agent. The temperature is then increased to about 60 to about 100 ° C. to initiate the polymerization. Optionally, additional monomers are added over a period of time during the reaction. After addition of the monomers, polymerization is generally accomplished until the addition of additional initiators.

[63] Luster
[64] Some formulations are often opaque by artificially incorporating a gloss material therein to achieve a cosmetically valuable pearlescent appearance known as a gloss material. Those skilled in the art are aware of the problems faced by formulators when consistently producing glossy formulations. This is discussed in detail in the literature described herein by Opacifiers and pearling agents in shampoos by Hunting, Cosmetic and Toiletries, Vol. 96, pages 65-78 (July 1981).

[66] Surprisingly, it has been found that incorporation of the substantially crosslinked alkali swellable acrylate polymer improves or increases the gloss appearance. Improved appearance, which can be seen visually, was observed earlier and in particular after 24 hours of aging of the composition compared to the composition containing no polymer. In addition, the polymer further prevents the settling of the shiny material, thereby significantly reducing the loss of gloss of the glossy appearance. In addition, polymerizable rheology modifiers allow to retain shiny particles or platelets at their optimal arrangement for maximum gloss appearance.

[70] The amount of various insoluble compounds that require stabilization will vary depending on their purpose, desired end result and efficacy. Thus, the amount may vary widely but will often be in the general range of about 0.1% to about 50% by weight based on the total weight of the stable composition.
[71] Cationic Dyes For Hair Dyeing
[72] Dyes that can be used in temporary hair dyes or color maintenance shampoos are generally soluble. Such dyes are generally known in the art and are generally referred to as cationic or basic dyes. Such dyes are commonly named in two different ways. The dye name (ie Basic Brown 16) relates to its INCl name (internationally named cosmetic ingredient) and / or its CTFA name (Cosmetic, Toiletry and Fragrance Association). Another way to refer to such dyes is to name them through their color index (eg Cl 12250), which is being used by the European Union. This series of numbers is described in the International Cosmetic Ingredient Dictionary and Handbook, for example, the 7 ^th Edition, 1997, published by the Cosmetic, Toiletry and Fragrance Association, Washington, DC, USA. These cationic dyes are commercially available as Aria too ^TM (Arianor) from Warner Zen Wilkinson (Warner Jenkinson). Special cationic dyes that can be used include basic blue 99 (Cl 12250), basic brown 17 (Cl 12551), basic red 76 (Cl 12245), basic yellow 57 (Cl 12719), as well as various azo dyes. And various anthraquinone dyes, such as Cl 56059).
[73] The amount of hair dye when used in a general temporary dyeing shampoo is from about 0.1 to about 5% by weight based on the total weight of the stabilized composition.
[74] Alkaline substances
[75] Polymeric rheology modifiers of the present invention are generally supplied in their acidic form. Such polymers modify the fluidity of the formulation by continuously polymerizing the carboxyl groups of the polymer. This causes ions to repel and the microgel network expands in three dimensions, increasing viscosity and other fluidity. The literature also refers to this as a space filling mechanism compared to an associative thickening mechanism.
[76] Thus, an alkaline substance is incorporated to neutralize the polymer, which preferably acts as a neutralizing agent. Various types of neutralizing agents can be used in the present invention, including inorganic and organic neutralizing agents. Examples of inorganic bases include, but are not limited to, alkali (particularly sodium, potassium and ammonium) hydroxides. Examples of organic bases include, but are not limited to, triethanolamine (TEA), L-arginine, aminomethyl propanol, tromethamine (2-amino 2-hydroxymethyl-1,3-propanediol), PEG-15 Cocoamine, diisopropanolamine, triisopropanolamine or tetrahydroxypropyl ethylene diamine. Alternatively, alkaline materials can be used, such as materials that incorporate pre-neutralized surfactants or neutralizers, or any other material that can increase the pH of the composition.
[77] Acid substances
[78] In the present invention, organic acids such as, for example, citric acid, acetic acid, alpha-hydroxy acid, beta-hydroxy acid, salicylic acid, lactinic acid, glycolic acid or natural fruit acid, or for example hydrochloric acid, nitric acid, sulfuric acid, sulfamic acid, Various acidic materials can be used, such as inorganic acids such as phosphorous acid, and combinations thereof. Such acidic materials may be added at various points in the process, but the addition of acidic materials after the addition of alkaline neutralizers significantly improves fluidity. This will be explained in more detail in the section "Back-Acid" Formulation Techniques.
[79] Other optional rheology modifiers
[80] The composition may optionally contain other flow modifiers along with the substantially crosslinked alkali swellable acrylate copolymer. Such polymers are known in the art and may include natural polymers, semi-synthetic (eg clay) polymers or synthetic polymers. Natural polymers or modified natural polymers include, but are not limited to, gums (eg, xanthan gum), celluloses, modified celluloses, starches or polysaccharides. Other synthetic polymers include, but are not limited to, crosslinked polyacrylates, alkali soluble polymers modified to be hydrophobic or nonionic urethane polymers modified to be hydrophobic. It is also known to adjust the viscosity using salt mixtures, which can be used in the present invention. When present in a composition, such rheology modifiers are generally used in amounts of about 0.01% to about 5% by weight stable composition.

[97] Formulation Technology
[98] The compositions of the present invention can be prepared in a variety of ways. Generally at least one substantially crosslinked alkali swellable acrylate copolymer is added to the water and mixed. The surfactant is then added to the aqueous polymerizable solution and mixed in there. (Alternatively, the surfactant is first added to water and then the polymer is added.) Then an alkaline substance, preferably a neutralizing agent such as sodium hydroxide, triethanolamine and the like is added and mixed to neutralize the solution. . The remaining additives containing the compound to be stabilized are then added with mixing to produce the desired final product.
[99] "Back-acid" formulation technology
[100] The polymerizable rheology modifier of the present invention does not substantially change the viscosity until a pH of about 5 or 6 is obtained. However, a pH of less than 6 is required to achieve the desired optimal performance in some home and personal care applications. This is limited to the case where such a polymer is used in the composition. In addition, it is difficult to form stable uses in lower pH ranges.
[101] Surprisingly, it has been newly discovered that when the pH of such compositions increases to almost neutral or even alkaline pH, and then the pH is subsequently reduced, the viscosity and yield stress generally remain unchanged or in practice often increase. Such formulation techniques will be referred to herein as "back-acid" thickening techniques. Thus, this formulation technology not only expands the range of use of such polymers, but also allows formulation in acidic pH ranges. In addition, a “back-acid” thickening process may be used to further increase the viscosity and stability of the formulated compositions in the weakly acidic and alkaline pH ranges.
[102] One or more acrylate copolymers, polymers and the like are added to the water and mixed. Subsequently, the surfactant is added to the aqueous polymerizable solution and mixed therein. The alkaline material is then added and mixed to increase the pH of the composition to at least about 5, preferably at least about 6 and most preferably at least about 6.5. Preferably, the alkaline material is a neutralizing agent such as sodium hydroxide, potassium hydroxide, triethanolamine, or another fatty acid amine neutralizing agent conventionally used for this purpose. Alternatively, other alkaline materials can be used, such as pre-neutralized surfactants. The pH should be about 0.5 or 2 pH units, preferably at least about 3, 4, or even 5 pH units above the final target pH of the composition. Then, an acidic substance is added to reduce the pH of the composition.
[103] Materials used to reduce the pH of such uses are acidic materials, preferably citric acid, acetic acid, alpha-hydroxy acid, beta-hydroxy acid, salicylic acid, lactinic acid, glycolic acid, natural fruit acid, or combinations thereof. Organic acids such as In addition, inorganic acids such as hydrochloric acid, nitric acid, sulfuric acid, sulfamic acid, phosphorous acid and combinations thereof can be used. The acid is generally from about 0.1% to about 20% by weight, preferably from about 0.2% to 15% by weight, more preferably from about 0.25% to about 10% by weight based on the total weight of the stabilized composition It is used in the amount of.
[104] The pH required to stabilize the compositions of the present invention will certainly vary depending on the particular application. Generally, the target pH range for use in personal care is about 3 to about 7.5, preferably about 4 to about 6, and the target pH range for use in home care is about 1 to about 12, Preferably from about 3 to about 10. More specifically, the desired pH when using generally insoluble silicone or shiny compound is about 5.5 to about 12, while the desired pH when stabilizing hair dye is about 5 to about 9.
[105] stability:
[106] A variety of products or compositions, such as for personal care, household care, industrial and institutional use, made using the substantially crosslinked alkali swellable acrylate copolymer rheology modifiers of the present invention are stable. The requirements for the stability of the particular composition will depend not only on its end market use, but also on the terrain of the area to be taken and sold. Subsequently, the acceptable shelf life is determined for each composition. By storage period is meant the amount of time the composition should be stable under normal storage and handling conditions, measured between the time the composition is prepared and the time it is finally sold for consumption purposes. Generally, personal care compositions require a three year shelf life, while home care compositions require a one year shelf life.
[107] To alleviate the need to conduct stability studies for more than one year, the formula will run stability tests under stressed conditions to predict the shelf life of the composition. In general, the accelerated test is carried out at an elevated normal temperature, generally 45 to 50 ° C. The composition should be stable at 45 ° C. for at least 2 weeks, preferably 1 month, more preferably 2 months or 3 months, most preferably 4 months or 5 months. In addition, lyophilization cycles are often used in which the composition is circulated between a freezing temperature of usually 0 ° C. and an ambient temperature of usually 20-25 ° C. The composition must go through at least one freeze drying cycle, preferably three cycles, more preferably five cycles.
[108] The products or compositions prepared according to the invention are considered stable if they meet at least one of the following criteria:
[109] 1. There should be no phase separation, precipitation or creaming of any substance in the composition. The composition must remain completely homogeneous throughout its bulk. Separation includes any component of any ingredient, including, but not limited to, insolubles, solubles, oils, and the like herein in the formulation. Two or more distinct layers or phases are defined as being presently visually identifiable.
[110] 2. The viscosity of the composition should not increase or decrease significantly over time, generally less than 50%, preferably less than 35%, more preferably less than 20%.
[111] 3. The pH of the composition should not increase or decrease by more than two pH units, preferably one or less pH units, more preferably one half pH units.
[112] 4. The flowability and texture of the composition should not change over time with the flowability and texture of what is not acceptable.
[113] The products or compositions according to the invention are considered to be unstable if they do not meet one or more of the above criteria.
[114] Additional information on stability test requirements can be found in the publication "References of the Fundamentals of Stability Testing; IFSCC Monograph Number 2", published on behalf of the International Federation of Societies of Cosmetic Chemists by Micelle Press, Weymouth, Dorset, England, and Cranford, New Jersey, USA).

(TopicQ1A, Step 2) Note for Guidance on Stability Testing of New Drug Substances and Products (Revision of CPMP / ICH / 380/95, released by consultation Nov. 99).
[124] The present invention will be better understood by reference to the following examples provided for purposes of illustration rather than limiting the scope of the invention.
[125] In some of the following examples, formulations will be prepared as follows. The acrylate copolymer was added to water and mixed. Then, the surfactant was added to the aqueous polymer composition and mixed. Subsequently, the mentioned neutralizing agents such as sodium hydroxide were added and mixed. Then, the remaining compounds or components were added in the order described above, usually with the addition of each component and mixing simultaneously. If necessary, an acid such as citric acid was subsequently added and mixed.
