    Field of the Invention
    [0001] The present invention relates to fluid cleaning compositions comprising beneficial agents, which also have improved release properties. The compositions are, in particular, but not exclusively, for treatments based on an aqueous medium, such as personal care products for bathing, cleaning fabrics and dishes. Background of the Invention
    [0002] Fluid compositions can comprise benefit agents by releasing benefits in advance, however, these compositions require structuring or thickening ingredients to prevent benefit agents from migrating under gravity. Summary of the Invention
    [0003] An object of the present invention is to provide a personal care composition for bathing and / or washing dishes and / or fabrics, which comprise beneficial agents and also with improved release properties.
    [0004] In accordance with the present invention, a fluid cleaning composition is provided comprising: (a) a surfactant combination comprising: (i) a synthetic surfactant; and (ii) a glycolipid biotensoactive which is present in a content in the range of 10-95% by weight of the total surfactant in said surfactant combination, and (b) a beneficial agent suspended in said cleaning fluid composition, the composition being characterized by the fact that the benefit agent comprises an encapsulated one.
    [0005] The substrate is preferably a fabric surface or a hard surface (such as a work surface, or cutlery or crockery) or human skin, hair or teeth.
    [0006] The present invention is particularly advantageous in that the glycolipidic biotensoactive offers rheological modification properties for compositions comprising suspending agents, whereby the beneficial agents are suspended without the need for additional suspension technologies, such as structuring, but , at the same time, the pseudoplasticity properties allow ease of release via smaller openings for precise release / dosing.

    [0009] Figure 3 is a graphic illustration of the rheology profile of Biotensative Shampoo (0%, 25%, 50%, 75%) in 1.5% NaCl.
    [0010] Figure 4 is a graphic illustration of the rheology profile of Biotensoactive Shampoo (0%, 25%, 50%, 75%) in 2.0% NaCl. Detailed Description of the Invention
    [0011] Throughout this description, where “%” is used, it is intended to mean% by weight (% by weight).
    [0012] Preferably, the glycolipidium comprises a ramnolipidium, however other glycolipidiums can be used, such as, soforolipidium, or any combination thereof.
    [0013] Preferably, the composition comprises an ionic salt. The salt preferably comprises any organic or inorganic cation, including, without limitation, alkali metal cations, Cs, Na, K, Ca, Mg, etc., with anions including halide anions, more preferably Cl. Other preferred salts comprise organic cations, for example, amides (- + NH-R) or ammonium cations or substituted forms thereof, for example, triethylammonium. Anions for organic cations can comprise any alkyl, aryl, arylalkyl component that can be short, medium, long, branched, cyclic or linear in size.
    [0014] Preferably, the composition comprises from 0.01 - 5% by weight by weight of the salt. In the case of NaCl, the content is preferably in the range of 0.5 - 2% by weight.
    [0015] Preferably, glycolipid is present in 25% - 75% by weight of the surfactant combination.
    [0016] The surfactant combination preferably comprises a synthetic anionic surfactant. "Anionic surfactants" are defined here as amphiphilic molecules comprising one or more functional groups that have a liquid anionic charge when in an aqueous solution at the normal washing pH between 4 and 11.
    [0017] Preferably, the alkali metal salts of organic sulfur reaction products having in their molecular structure an alkyl component, containing from about 6 to 24 carbon atoms, more preferably still greater than 12 carbon atoms and preferably also one component selected from the group consisting of sulfonic and sulfuric acid ester components. Additionally or alternatively, the anionic surfactant preferably has low levels of ethoxylation, preferably comprising 1-12 units of ethylene oxide per molecule, more preferably 1-3 and even more preferably 1. The ethylene oxide units can be an average.
    [0018] It is highly beneficial to provide the formulation to scientists with the freedom to use carbon chains of longer lengths and / or low levels of ethoxylation, and not just on a cost basis. However, these factors increase calcium intolerance and, therefore, such surfactants are advantageous selections for the present invention.
    Preferred anionic surfactants include primary alkyl sulfates (PAS), for example, sodium lauryl sulfate (SLS) and, for example, alkyl sulfate ether, such as sodium lauryl ether sulfate (SLES), soaps, sulfonate ester fatty acid, fatty acid sulfates or sulfonates; alkyl benzene sulfonates (LAS), sulfosuccinate esters, olefin sulfonates, paraffin sulfonates and organic phosphates; fatty alcohol sulfates; alkyl phenol sulfate ether; grease acyl isethionate products with products comprising grease acyl isethionate and free fatty acid and / or fatty acid salt; alkyl sulfonates such as sodium alkane sulfonate. Preferred anionic surfactants are the alkaline salts (ammonium or triethylammonium, for example) and alkaline earth metal salts from the anions above. The oil / alcohol source can be derived from a plant or animal, for example, from coconut, palm or tallow, etc.
    [0020] The surfactant combination is present in the fabric or hard surface washing compositions in a content of 3 to 85% by weight, preferably from 3 to 60% by weight, more preferably from 3 to 40% by weight, more preferably still from 3 to 35% by weight.
    [0021] The surfactant combination is present in personal care compositions for washing (human skin and hair) at a level of 5 to 60%, preferably from 10 to 40% of surfactant, and although cosmetic compositions do not need to understand any surfactant, but preferably they comprise from 1% to 30% by weight, more preferably from 1 to 15% by weight of surfactant.
    [0022] The present invention is particularly advantageous in suspending larger components compared to more expensive rheology modifiers.
    [0023] Consequently, it is preferred that the beneficial agent be macroscopic, that is, greater than or equal to a diameter of 3 micrometers.
    [0024] The encapsulated preferably comprises a wrap or capsule surrounding a core, the core comprising the beneficial agent.
    [0025] Preferably, the encapsulated comprises microcapsules. Preferably, the encapsulated comprises shear / pressure sensitive action encapsulated, the sensory benefit agent contained therein being released in response to mechanical force (e.g., friction stress, pressure, shear) on the encapsulated. Urea-formaldehyde and melamine-formaldehyde microcapsules can be used to provide the necessary friction or pressure based on the release mechanism.
    [0026] Additionally or alternatively, the encapsulated can also be of diffusive action, and the sensory benefit agent contained within them is also released through diffusion through the outer wall of the encapsulated.
    [0027] Commercially available melamine-formaldehyde friction release encapsulates are the encapsulated series of Aroma Ball Type 1 and Aroma Ball S, for example, Polychrome, Korea.
    [0028] Preferably, the wrap is a melamine-formaldehyde wrap. The encapsulated wrapper is preferably comprised of materials including, but not limited to, polyurethane, polyamide, polyolefin, polysaccharide, protein, silicone, lipid, modified cellulose, gums, polyacrylate, polyphosphate, polystyrene, polyesters or combinations of these materials. Another encapsulating material that can be used efficiently in the present invention is a material such as polymethylmethacrylate. Preferred encapsulating polymers include those formed from condensates of melamine formaldehyde or urea formaldehyde, as well as similar types of aminoplast. The wrapper most preferably comprises formaldehyde melamine.
    [0029] Additionally, microcapsules produced via simple or complex gelatin coacervation are suitable for use in compositions of the present invention.
    [0030] A representative process used for encapsulating aminoplast is described in US patent 3,516,941, despite the fact that it is recognized that many variations with respect to materials and process steps are permissible. A representative process used for encapsulating gelatin is described in US patent 2,800,457, despite the fact that it is recognized that many variations with respect to materials and process steps are permissible. Both of these processes are described in the context of fragrance encapsulation for use in consumer products in US patents 4,145,184 and US 5,112,688, respectively.
    [0031] Encapsulation can provide voids in pores or interstitial openings, depending on the encapsulation techniques employed.
    [0032] Fragrance capsules known in the art and suitable for use in the present invention comprise a wall or wrapper comprising a cross-linked three-dimensional network of an amino acid resin, more specifically a cross-linked substituted or unsubstituted acrylic acid polymer or copolymer. a urea-formaldehyde pre-condensate or a melamine-formaldehyde pre-condensate.
    [0033] The formation of microcapsules using mechanisms similar to the previous mechanism, using (i) pre-condensed melamine-formaldehyde or urea-formaldehyde and (ii) polymers containing substituted vinyl monomer units having proton donor functional group components (by example, sulfonic acid groups or carboxylic acid anhydride groups) attached to them is described in US patent 4,406,816 (2-acrylamido-2-methyl-propane sulfonic acid groups), Published Patent Application GB 2,062,570 A (styrene sulfonic acid groups) and Published Patent Application GB 2,006,709 A (carboxylic acid anhydride groups).
    [0034] The encapsulated can additionally comprise a carrier oil in the core. Carrier oils are hydrophobic materials that are miscible in volatile beneficial agent materials used in the present invention. Appropriate oils are those that have a reasonable affinity for the beneficial agent. When the beneficial agent is a perfume, appropriate materials include, but are not limited to, triglyceride oil, mono and diglycerides, mineral oil, silicone oil, diethyl phthalate, polyalpha olefins, castor oil and isopropyl myristate. Preferably, the oil is a triglyceride oil, more preferably a capric / caprylic triglyceride oil.
    [0035] The particle size and the average diameter of the capsules can vary from about 10 nanometers to 1000 microns, preferably from 50 nanometers to about 100 microns, more preferably from about 2 to 40 microns, even more preferably from 4 up to 15 microns. A particularly preferred range is from about 5 to 10 microns, for example, from 6 to 7 microns. The distribution of the capsules can be narrow, wide or multimodal. Multimodal distributions can be composed of different types of capsule chemicals.
    [0036] The wrap can additionally comprise a deposition aid, which is preferably covalently bonded.
    [0037] A preferred deposition aid is a polysaccharide. The polysaccharide preferably has a β-1,4-linked backbone.
    [0038] Preferably, the polysaccharide is a cellulose, cellulose derivative, or other β-1,4-linked polysaccharide having affinity for cellulose, such as polymanane, polyglucan, polyglucomannan, polyoxyglucan and polygalactomannan or a mixture thereof. More preferably, the polysaccharide is selected from the group consisting of polyoxyglucan and polygalactomannan.
    [0039] Highly preferred polysaccharides are selected from locust bean flour, tamarind gum, xyloglucan, non-ionic guar gum, cationic starch and mixtures thereof. Most preferably, the deposition aid is locust bean meal.
    [0040] Preferably, the polysaccharide backbone has only β-1,4 bonds. Optionally, in addition to the β-1,4 bonds, the polysaccharide has bonds such as β-1,3 bonds. Thus, optionally some other connections are present. Main polysaccharide chains that include some material that is not a saccharide ring are also within the scope of the present invention (either terminal or within the polysaccharide chain).
    [0041] The polysaccharide can be straight or branched. Many naturally occurring polysaccharides have at least some degree of branching, or at any rate, at least some saccharide rings are in the form of side groups (which are, therefore, not counted in themselves, in determining the degree of substitution) or in a polysaccharide backbone.
    [0042] Preferably, the polysaccharide is present in levels between 0.1% to 10% w / w by weight of the total amount of the particle.
    [0043] The deposition aid, which is preferably a polysaccharide, is attached to the particle by means of a covalent bond, by entrainment or by strong adsorption, preferably by means of a covalent bond. The term "by entrainment" is used here to mean that the deposition aid is adsorbed on the particle as the polymerization proceeds and the particle grows in size, part of the adsorbed deposition aid is enclosed within the particle. Thus, at the end of the polymerization, part of the deposition aid is closed and is attached to the polymeric matrix of the particle, while the rest is free to extend into the aqueous phase.
    [0044] The term strong adsorption, as used here, is intended to mean strong adsorption of the deposition aid on the surface of the particle; such adsorption may, for example, occur due to hydrogen bonding, Van der Waals attraction or electrostatic attraction between the deposition aid and the particle.
    [0045] The deposition aid, therefore, is mainly attached to the surface and is not, in any significant amount, distributed through the internal volume of the particle. This is different from grafted polymers, in which, for example, a polysaccharide can be grafted along the length of a polymeric chain. A particle that is formed from a grafted copolymer can, therefore, contain polysaccharide through the internal volume of the particle, as well as on the surface of the particle, and the present invention is not intended to cover such a particle. Thus, the particle that is produced when using a polysaccharide, as the deposition aid according to the process of the present invention can be imagined as a "capillary particle", which is different from a grafted copolymer. This aspect of the present invention provides opportunities for significant cost savings for the manufacturer, because much less deposition aid is required to achieve the same level of activity as systems using polysaccharide copolymers.
    [0046] The deposition aid is present in the outermost portion of the wrapper, which is made of melamine formaldehyde polymer having a thickness of 5 to 20 nm.
    [0047] Polyesters of terephthalic acid and other aromatic dicarboxylic acids can be used as deposition aids having dirt-releasing properties, in particular, the so-called PET / POET (polyethylene terephthalate / (polyoxyethylene terephthalate) and PET / polyesters PEG (polyethylene terephthalate / polyethylene glycol).
    [0048] The polymer must have at least one mole of the free OH group per polymer molecule to allow covalent bonding with the reactive dye (s). More preferably, the polymer comprises at least two free OH groups. Preferably the free OH groups are the terminal groups of the polymer.
    [0049] Preferably, the oxyalkyleneoxy [-O (CH2) tO-] is selected from: oxy-1,2-propyleneoxy [-OCH2CH (Me) O-]; oxy-1,3-propyleneoxy [O-CH2CH2CH2O-]; and, oxy-1,2-ethyleneoxy [-OCH2CH2O-] (t is an integer). As is evident, one or more of the CH2 groups of the oxyalkyleneoxy can be substituted by C1 to C4 alkyl group (s).
    [0050] Polyoxyalkyleneoxy facilitates the solubility of the polymer in water. Preferably, the polyoxyalkyleneoxy [-O (CH2) w-] sO- is selected from: polyoxy-1,2-propyleneoxy [-O (CH2CH (Me) -] sO-; polyoxy-1,3-propyleneoxy [O - CH2CH2CH2-] sO-; e, polyoxy-1,2-ethyleneoxy [O-CH2CH2-] sO-. Polyoxyalkyleneoxy can be a mixture of different oxyalkyleneoxy Different types of polyoxyalkyleneoxy may be present in the polymer (sew are integers) .
    [0051] Preferably the phenyl dicarboxylate is a 1,4-phenyl dicarboxylate. Preferably, the phenyl dicarboxylate is in the form: -OC (O) C6H4C (O) O-.
    [0052] Examples of preferred polymers are polymers PET / POET (Polyethylene terephthalate / Polyoxyethylene terephthalate), PEG / POET (Polyethylene glycol / Polyoxyethylene terephthalate) or PET / PEG (Polyethylene terephthalate / Polyethylene glycol). The most preferred of all is a PET / POET.
    [0053] The structure of a preferred polymer is found below:
    where: R2 is selected from H or CH3, preferably H; b is 2 or 3, preferably 2; y is 2 to 100, preferably 5 to 50; nor are they independently 1 to 100, preferably 2 to 30; and, the terminal (end) groups of the polymer are (CH2) bOH.
    [0054] Polymers can be synthesized through a variety of routes, for example, an esterification reaction of dimethyl terephthalate with ethylene glycol and polyethylene glycol, this reaction is discussed in Polymer Bulletin 28, 451-458 (1992). Another example may be the direct esterification of terephthalic acid with ethylene glycol and / or propylene glycol and polypropylene glycol. An additional example may be a transesterification of a polyethylene terephthalate with a polyethylene glycol or polypropylene glycol.
    [0055] It is preferable that the numerical average molecular weight of the polymer is in the range of 1000 to 50000, preferably the average molecular weight of the polymer is in the range of 1000 to 15000, more preferably from 2000 to 10000.
    [0056] Preferably, the encapsulated benefit agent comprises a dermatological benefit agent or an olfactory benefit agent and / or can be a volatile benefit agent. Sensory benefit agents may also have benefits for hair and / or hard surfaces and / or fabrics.
    [0057] Suitable volatile beneficial agents include, but are not limited to, perfumes, insect repellents, essential oils, sensory agents, such as menthol and aromatherapy actives, preferably perfumes. Mixtures of volatile beneficial agents can be used.
    [0058] The total amount of the beneficial agent is preferably 0.01 to 10% by weight, more preferably from 0.05 to 5% by weight, even more preferably from 0.1 to 4.0%, most preferably from 0.15 to 4.0% by weight, based on the total weight of the composition.
    [0059] A preferred benefit agent is a perfume. The compositions of the present invention also comprise an agent of non-confined volatile benefit (also called non-encapsulated). When the volatile beneficial agent is a perfume, the perfumes described below are suitable for use as the encapsulated volatile beneficial agent and also as the unconfined perfume component.
    [0060] Any appropriate perfume or perfume mixture can be used. Usable perfume components include materials from both natural and synthetic sources. They can be simple compounds or mixtures. Specific examples of such components can be found in the current literature, for example, in Fenaroli's Handbook of Flavor Ingredients, 1975, CRC Press; Synthetic Food Adjuncts, 1947 by M. B. Jacobs, edited by Van Nostrand; or Perfume and Flavor Chemicals by S. Arctander 1969, Montclair, N.J. (USA). These substances are well known to the person skilled in the art of perfumery, flavoring production, and / or flavoring consumer products, that is, to impart an odor and / or flavor or flavor to a traditionally scented or flavored consumer product, or to modify the odor and / or taste of said consumer product.
    [0061] The term perfume, in this context, does not only mean a completely formulated fragrance product, but also selected components of that fragrance, particularly those that tend to get lost, such as so-called "top notes".
    [0062] The top notes are defined by Poucher (Journal of the Society of Cosmetic Chemists 6 (2): 80 [1955]). Examples of well-known top notes include citrus oils, linalool, linalyl acetate, lavender, dihydromyrcenol, rose oxide and cis-3-hexanol. For top notes typically comprising 15-25% by weight of a perfume composition in those embodiments of the invention that contain an increased level of top notes, it is envisaged that at least 20% by weight must be present within the encapsulated.
    [0063] Part or all of the perfume or pro-fragrance can be encapsulated, whose typical perfume components are advantageous to encapsulate, including those with a relatively low boiling point, preferably those with a boiling point of less than 300, preferably 100-250 degrees Celsius and pro-fragrances that can produce such components.
    [0064] It is also advantageous to encapsulate perfume components that have a low Clog P (that is, those that will be divided into water), preferably with a Clog P of less than 3.0. These relatively low boiling point and relatively low Clog P materials have been called “late flowering” ingredients and include the following materials:
    [0065] Alyl Caproate, AmylAcetate, Amyl Propionate, Anisic Aldehyde, Anisol, Benzaldehyde, Benzyl Acetate, Benzyl Acetone, Benzyl Alcohol, Benzyl Formiate, Benzyl Iso Valerate, Benzyl Propionate, Beta Hexenol Range, Camphor Gum, Laevo-Carvone -Carvone, Cinnamic Alcohol, Cinamyl Formiate, Cis-Jasmone, cis-3-Hexenyl Acetate, Cuminic Alcohol, Cyclal C, Dimethyl Benzyl Carbinol, Dimethyl Benzyl Carbinol Acetate, Ethyl Acetate, Ethyl Acet Acetate, Ethyl Amyl Ketone, Ethyl Benzoate , Ethyl Butyrate, Ethyl Hexyl Ketone, Ethyl Phenyl Acetate, Eucalyptol, Eugenol, Fenchil Acetate, Flower Acetate (Decenyl Acetate Tricycle), Frutene (Decenyl Propionate Tricycle), Geraniol, Hexenol, Hexenyl Acetate, Hexyl Acetate, Hexyl Tractate Hydroxycitronelal, Indone, Isoamyl Alcohol, Iso Mentone, Isopulegil Acetate, Isoquinolone, Ligustral, Linalool, Linalool Oxide, Linalyl Formiate, Mentone, Mentyl Acetophenone, Methyl Amyl Ketone, Methyl Anylanate, Methyl Benzo Methyl Eugenol, Methyl Heptenone, Methyl Heptine Carbonate, Methyl Hepty Ketone, Methyl Hexyl Ketone, Methyl Phenyl Carbinyl Acetate, Methyl Salicylate, Methyl-N-Methyl Anthranylate, Nerol, Octalactone, Octy Alcohol, p-Cresol, p-Cresol Methyl Ether p-Methoxy Acetophenone, p-Methyl Acetophenone, Phenoxy Ethanol, Phenyl Acetaldehyde, Phenyl Ethyl Acetate, Phenyl Ethyl Alcohol, Phenyl Ethyl Dimethyl Carbinol, Prenyl Acetate, Propyl Bornate, Pulegone, Rose Oxide, Safrole, 4-Terpinenol, Alpha-Terpinenol, Alpha , and / or Viridine.
    [0066] When non-encapsulated or “free” perfume ingredients are used, the preferred ones are those hydrophobic perfume components with a Clog P above 3. As used here, the term “Clog P” means the logarithm calculated in base 10 of the octanol / water partition coefficient (P). The octanol / water partition coefficient of a perfume raw material (PRM) is the ratio between its equilibrium concentrations in octanol and water. Since this measure is a ratio of the equilibrium concentration of a PRM in a non-polar solvent (octanol) to its concentration in a polar solvent (water), Clog P is also a measure of the hydrophobicity of a material - the greater the value of Clog P, the more hydrophobic the material is. Clog P values can be easily calculated from a program called "CLOG P" which is available from Daylight Chemical Information Systems Inc., Irvine Calif., USA. The octanol / water partition coefficients are described in more detail in US patent 5,578,563.
    [0067] Perfume components with a ClogP above 3 include: Iso E super, citronelol, Ethyl cinnamate, Bangalol, 2,4,6-Trimethylbenzaldehyde, Hexyl cinnamic aldehyde, 2,6-Dimethyl-2-heptanol, Diisobutilcarbinol, Ethyl salicylate, Phenethyl isobutyrate, Ethyl hexyl ketone, Propyl amyl ketone, Dibutyl ketone, Heptil methyl ketone, 4,5-Dihydrotoluene, Caprylic aldehyde, Citral, Geranial, Isopropyl benzoate, Cyclohexaneepropionic acid, Caprylic acid, Aldehyde, Canfolene aldehyde, Aldehyde acid , Cuminaldehyde, 1-Ethyl-4-nitrobenzene, Heptyl formate, 4-Isopropylphenol, 2-Isopropylphenol, 3-Isopropylphenol, Allyl disulfide, 4-Methyl-1-phenyl-2-pentanone, 2-Propifuran, Allyl caproate, Styrene, Isoeugenyl methyl ether, Indonaftene, Diethyl suberate, L-Mentona, Mentone racemic, p-Cresyl isobutyrate, Butyl butyrate, Ethyl hexanoate, Propyl valerate, n-Pentyl propanoate, Hexyl acetate, Methyl heptanoate, trans-3,3,5-Trimethylcyclo -hexanol, 3,3,5- Trimethylcyclohexanol, Ethyl p-anisate, 2-Ethyl-1-hexanol, Benzyl isobutyrate, 2,5-Dimethylthiophene, Isobutyl 2-butenoate, Caprylnitrile, gamma-Nonalactone, Nerol, trans-Geraniol, 1-Vinyl-heptanol, Eucalyptol, 4-Terpinenol, Dihydrocarveol, Ethyl 2-methoxybenzoate, Ethyl cyclohexanecarboxylate, 2 -Ethylhexanal, Ethyl amyl carbinol, 2-Octanol, 2-Octanol, Ethyl methylphenylglycidate, Diisobutyl ketone, Cumarone, Propyl isovalerate, Isobutyl butanoate, Isopentyl propanoate, 2-Ethylbutyl acetate, 6-Methyl-tetrahydroquinoline, Eugen , Ethyl dihydrocinamate, 3,5-Dimethoxytoluene, Toluene, Ethyl benzoate, n-Butyrophenone, alpha-Terpineol, Methyl 2-methylbenzoate, Methyl 4-methylbenzoate, Methyl 3, methylbenzoate, sec.

    [0068] In the compositions of the present invention there are expected to be four or more, preferably five or more, more preferably six or more or even seven or more different perfume components from the given list of late flowering perfumes given above and / or the list of perfume components with a Clog P above 3 present in the perfume.
    [0069] The benefit agent can also provide insect repellency. In chemical terms, most repellent assets belong to one of four groups: amides, alcohols, esters or ethers. Those suitable for use in the present invention are liquids or solids with a relatively low melting point and a boiling point above 150 ° C, preferably liquids. They evaporate slowly at room temperature.
    [0070] Advantageously, the insect repellent is related to the perfume species (more preferably, the component is in both classes). The most commonly used insect repellents include: DEET (N, N-diethyl-m-toluamide), lemon eucalyptus essential oil (Corymbia citriodora) and its active compound p-menthane-3,8-diol (PMD), Icaridin, also known as Picaridin, D-Limonene, Bayrepel and KBR 3023, Nepetalactone, also known as "cat weed oil", Citronella oil, Permetrin, Neem oil and Swamp Myrtle.

    [0072] Encapsulated insect repellents are mosquito repellents available from Celessence, Rochester, England: Celessence Repel, containing the active ingredient Saltidin ™ and Celessence Repel Natural, containing the active Citrepel ™ 75. Saltidin is a man-made molecule developed originally by Bayer Corporation. Citrepel is produced from eucalyptus oils and has a high content of p-menthane-3,8-diol (PMD). A preferred non-encapsulated repellent is Citriodiol ™ supplied by Citrefine.
    [0073] Preferably, the benefit agent comprises so-called "aromatherapy" materials. They include essential oil components such as Salva Esclarea, Eucalyptus, Geranium, Lavender, Macis Extract, Neroli, Nutmeg, Mint, Sweet Violet and Valerian Leaf.

    1. Rheology Measurement Method
    [0104] A shampoo formulation was produced on a bench scale in accordance with the above Protocol. The composition of the formulations varied by the fact that the levels of total surfactant had been gradually replaced with varying amounts of microbiologically derived biotensoative. The rheological properties were then evaluated using an Anton Paar ASC Rheometer at 25 ° C.
    [0105] Rheology measurements were performed with toothed rotational geometry. The pendulum used was the CC27 / P2 SN9625 with the toothed cup related to this geometry. Each bowl contained between 24 g and 26 g of
    [0106] samples. All bowls were maintained at 25 ° C by means of a Jumbalo F32 bath.
    [0107] Rheological measurements include three different steps: - Step 1: measurements of the shear stress control from 0.01 Pa to 400 Pa. - Step 2: measurements of the shear rate control from 0.1 s-1 to 1200 s-1. - Step 3: measurements of the control of the shear rate from 1200 s-1 to 0.1 s-1.
    [0108] After the experimental measurements were made, the data were collected from the Rheoplus software for analysis and this is shown in tables 1-5 below and also in figures 1-4. Table 2: Rheology of Non-biotensoactive Shampoo (100% SLES) / Varied NaCl
