A water-soluble and/or water-swellable hybrid polymer comprising: (i) from 5 wt.-% to 95 wt.-% water-soluble and/or water-swellable polysaccharide polymer selected from the group consisting of xanthan gum, carrageenan, guar gum, chitosan, alginate and combinations thereof; (ii) from 5 wt.-% to 95 wt.-% synthetic polymer comprising up to 100 mol-% repeating units according to Formula (1a): ##STR00001##
wherein components (i) and (ii) are polymerized by radical precipitation polymerization in a polar solvent.

This invention concerns a transparent composition comprising at least a first amphoteric water-soluble polymer, which comprises: A units of a cationic monomer selected from: acidified or quaternised dimethylaminoethyl acrylate salts, acidified or quaternised dimethylaminoethyl methacrylate salts, acidified or quaternised dimethylaminopropyl acrylamide salts, and acidified or quaternised dimethylaminopropyl methacrylamide salts, and mixtures thereof; B units of 2-acrylamido-2-methylpropanesulphonic acid and/or salts thereof; and optionally C units of acrylamide,

characterised in that the molar ratio between the A units of cationic monomer and the B units of 2-acrylamido-2-methylpropanesulphonic acid and/or salts thereof is between 0.4 and 1.4.

Personal care compositions comprising a polymer and a trisolvent system, and the use of the compositions in removing oily soils (such as grease or sebum).

The instant disclosure relates to a rheological-modifying and stabilizing polymer blend, cosmetic compositions comprising the polymer blend, and methods for stabilizing, for modifying viscosity, and for treating the skin using the polymer blend or using cosmetic compositions comprising the polymer blend. The rheological-modifying and stabilizing polymer blend comprises: (i) a carbomer; (ii) acrylates/C10-30 alkyl acrylate crosspolymer; and (iii) ammonium acryloyldimethyltaurate/steareth-25 methacrylate crosspolymer.

The salt-stable cosmetic composition is in the form of a low viscosity emulsion (oil in water) and is especially stable at high electrolyte contents and includes a salt-stable polymeric system comprising a polymer blend such that the salt-stable cosmetic composition resists phase separation, pilling and gellifying at high salt content, conferring a flowable, lightweight lotion-type texture.

The present invention relates generally to compositions and methods of using the same such as, for example, methods of treating the skin of a subject using a composition as described herein. The composition may comprise a diluent, a solvent, a penetration enhancing agent, a skin brightening agent, a skin renewing agent, a thickening agent, an anti-irritant, a chelating agent, an active pharmaceutical ingredient (API), optionally a pH adjustment agent, and optionally a preservative. The composition may further comprise L-arginine and/or L-citrulline and/or esters and/or derivatives thereof.

A method for treating human keratin fibers such as the hair is described and comprises the application to the keratin fibers of a dye composition comprising at least one cationic acrylic copolymer and at least one pigment, and the application to the dyed keratin fibers of a makeup-removing composition comprising at least one hydrocarbon oil.

Provided is a composition including: an acrylamide compound represented by general formula (1) below; urethane (meth)acrylate having a SI value of 3 or less in a skin sensitization test; and a polymerization initiator having a molecular weight of 800 or greater, ##STR00001##
where in general formula (1), R.sub.1 represents an alkyl group containing 1 through 6 carbon atoms, X represents an alkylene group containing 1 through 6 carbon atoms, and Y represents any one selected from the group consisting of general formula (2) below and general formula (3) below, ##STR00002##
where in general formula (2), R.sub.2 represents an alkyl group containing 1 through 10 carbon atoms, and * represents a binding site with X above, ##STR00003##
where in general formula (3), R.sub.2 represents an alkyl group containing 1 through 10 carbon atoms, and * represents a binding site with X above.

The present invention is direct to a hair care composition comprising from about 8 to about 17% of one or more surfactants; from about 0.1-0.25% of salicylate salts or acids; from about 0.1-0.25% of benzoate salts or acids wherein there is a weight ratio of about 1:1 to 2.5:1 for the salicylate salts or acids to sodium benzoate salts or acids.

The present invention is directed to a hair care composition having an effective amount of a 2-pyridinol-N-oxide material and an effective amount of an iron chelator; wherein the combination of the iron chelator and the 2-pyridinol-N-oxide material provides high anti-fungal efficacy.
