The present invention is directed to a cosmetic composition precursor that is rapidly hydratable and conducive to creating a personalized end-product. This invention thus relates to a cosmetic composition precursor having fatty acid, inorganic base, and high HLB surfactants and methods of using said precursors in creating the end-product. The invention also relates to end-use compositions made from the hydratable cosmetic composition precursor of the invention.

The invention relates to a composition in the form of a nanoemulsion or microemulsion, comprising: —a first fatty acid ester of polyglycerol which is chosen from a fatty acid ester of polyglycerol formed from at least one acid comprising an alkyl or alkenyl chain containing from 12 to 20 carbon atoms and from 3 to 6 glycerol units; —a second fatty acid ester of (poly)glycerol (c) which is chosen from a fatty acid ester of (poly)glycerol formed from at least one acid comprising an alkyl or alkenyl chain containing from 6 to 18 carbon atoms and from 1 to 3 glycerol units; —at least one organopolysiloxane elastomer; —at least two acrylic acid-based polymers that are different from one another; —at least one amphiphilic polymer comprising at least one 2-acrylamidomethylpropanesulfonic acid (AMPS) unit; —at least one oil; —water. The invention also relates to a cosmetic treatment process for keratin materials such as the skin, by application of such a composition.

A topical cleansing composition for stimulating the production of antimicrobial peptides on the skin is disclosed. The topical cleansing composition includes an active ingredient comprising one or more of a natural extract and a polypeptide; one or more surfactants; and water. The topical cleansing composition increases the concentration of antimicrobial peptides on skin, as compared to an otherwise identical topical composition without the active ingredient.

A non-antimicrobial cleansing composition is disclosed comprising from about 10.0 wt. % to less than about 40 wt. % of one or more C.sub.1-C.sub.8 alcohols; about 0.5 wt. % to about 10.0 wt. % of at least one primary surfactant; 0 wt. % to about 10.0 wt. % of at least one secondary surfactant, with the primary and secondary surfactants having an HLB value greater than 8; a pH adjusting agent; and water. The composition does not achieve a microbial kill level greater than 2.0 log.

The present invention relates to a water-in-oil surfactant consisting of a mixture of compounds of formula (I): ##STR00001##
wherein the compound of formula (I) has an average degree of polymerisation n of between 4 and 6,
R1, R2 and R3 being, independently of one another, a hydrogen atom or a group R4 derived from at least one carboxylic acid,
the carboxylic acid being 12-hydroxystearic acid or a mixture of 12-hydroxystearic acid and ricinoleic acid. The present invention also relates to a surfactant composition and to a cosmetic composition comprising this surfactant.

The present invention relates to a skin cleansing composition which can sufficiently exhibit an excellent keratotic plug-removing effect without a burden such as pain and irritation on the skin. The skin cleansing composition comprises 0.08 mass % or more and 35 mass % or less of (X) 2-amino-2-methyl-1-propanol and has a pH of 9.3 or more and 12.5 or less at 25° C.

An oral care composition and methods for the same are disclosed herein. The oral care composition may include an orally acceptable vehicle, an anionic surfactant, and a nonionic surfactant. The anionic surfactant may include a C6-C18 fatty acid glutamate or a salt thereof, and the nonionic surfactant may include a C6-C18 alkyl polyglucoside. A weight ratio of the nonionic surfactant to the anionic surfactant may be from about 0.25:1 to about 9:1, or from about 1.8:1 to about 2.2:1.

A computer implemented method for determining performance properties of an oil-containing product for cosmetics, the oil-containing product for cosmetics comprising different oils forming a mixture, the method comprising the steps of: providing to a processing device via an input channel o performance properties for each of the different oils o a measure for the ratio of the different oils in the mixture, o a data driven model and/or a rigorous model determining with a processing device determined performance properties of the oil-containing product for cosmetics comprising the mixture, based on o the data driven model o the performance properties for each of the different oils o the measure for the ratio of the different oils in the mixture, providing via an output channel o the determined performance properties of the oil-containing product for personal care and/or o the measure for the ratio of the different oils in the mixture and/or o a formulation of the mixture, and or o a formulation of the oil-containing product for personal care.

A hair care formulation is provided, comprising: a dermatologically acceptable vehicle; a dermatologically acceptable oil; and a deposition aid polymer, wherein the deposition aid polymer is a dextran polymer functionalized with an amine group; wherein the dextran polymer has a weight average molecular weight of 100,000 to 650,000 Daltons; and wherein the deposition aid polymer enhances deposition of the dermatologically acceptable oil from the hair care formulation onto mammalian hair.

A stable shampoo composition that contains a surfactant system with anionic and amphoteric surfactants, a cationic polymer having a charge density of 1.7 meq/g to 2.1 meq/g, and 1% to 1.5% inorganic salt.
