A sunscreen concentrate in the form of a stable, uniform dispersion comprising, by weight:

Sunscreen concentrate

This invention relates to an acidic non-irritating lotion, cream or ointment for rejuvenating skin and hair which comprises a micronized, homogenized hydrogel of a crosslinked N-vinyl lactam polymer and an organic rejuvenating agent selected from the group consisting of pyruvic acid, a mono- or poly-carboxylated C.sub.1 to C.sub.20 hydrocarbon optionally substituted with from 1 to 3 hydroxy groups and ammonium and alkali metal salts of said acids and mixtures thereof including mixtures of the acids and/or said salts.

Non-irritating skin and hair rejuvenating compostion having a pH between

The invention relates to properties and uses of N-hydrocarbon substituted lactams, particularly N-alkyl substituted lactams having the formula ##STR1## wherein R' is a hydrophobic radical such as linear or branched chain alkyl group containing from 8 to 27 carbon atoms, most preferably micelle forming pyrrolidones having 12 to 16 carbon atoms in the R' group. The invention particularly relates to the uses of the N-hydrocarbon substituted lactams which involve surfactant properties, such as solubility, wetting, viscosity building, emulsifying and/or complexing properties.

Surface active lactams

What is provided herein are conditioning hair care compositions comprising (a) a stabilized silicone product obtained by in situ polymerization of a water-soluble vinyl monomer, preferably vinylpyrrolidone, in the presence of discrete microdroplets of a silicone oil in water, (b) an emulsifiers, (c) a thickener, optionally, (d) a cationic surfactant, and the balance being (e) water.

Conditioning hair care compositions

What is provided herein are conditioning shampoo hair care compositions comprising (a) a stabilized silicone product obtained by in situ polymerization of a water-soluble vinyl monomer, preferably vinylpyrrolidone, in the presence of discrete microdroplets of a silicone oil in water, (b) a surfactant, (c) a foam stabilizer, and the balance being (d) water.

Conditioning shampoo hair care compositions

What is provided herein are conditioning hair care compositions comprising (a) a stabilized silicone product obtained by in situ polymerization of a water-soluble vinyl monomer, preferably vinylpyrrolidone, in the presence of discrete microdroplets of a silicone oil in water, (b) a surfactant, and the balance being (c) water.

What is provided herein are hair and skin care compositions containing discrete microdroplets of an oil in water stabilized by in situ polymerization of a water-soluble vinyl monomer and a water-soluble acryl comonomer. The stabilized microdroplets are prepared by dispersing the oil in water, adding the water-soluble vinyl monomer, preferably vinylpyrrolidone, with the comonomer, and copolymerizing the monomer and comonomer in situ such that the oil is stabilized in the resulting copolymer solution as discrete microdroplets.

Hair and skin care compositions containing discrete microdroplets of an

What is provided herein is a sunscreen composition consisting essentially of a crosslinked, neutralized terpolymer of maleic anhydride, a C.sub.1 -C.sub.5 alkyl vinyl ether and a C.sub.12 -C.sub.14 alpha-olefin monomer as a thickener; water; an ultraviolet sunscreening agent; and an emulsifier. In the preferred form of the invention, the monomers are present in a molar ratio of about 1:0.90-0.99:0.01-0.10, respectively, and are crosslinked with about 2-8 wt. % of a crosslinking agent based on the total weight of the monomers. Suitably, the crosslinked terpolymer is neutralized to increase water solubility.

Sunscreen composition

What is provided herein are cosmetic compositions for the care of hair and skin containing about 0.2 to 10% by wt. of a strongly swellable, moderately crosslinked polyvinylpyrrolidone polymers in the form of fine, white powders characterized by (a) an aqueous swelling parameter defined by its gel volume of about 15 to 150 ml/g, (b) a Brookfield viscosity in 5% aqueous solution of at least about 10,000 cps, and (c) being prepared directly by a precipitation polymerization process in an organic solvent, in the presence of about 0.2 to 1% by weight of vinylpyrrolidone of a multifunctional crosslinking agent, preferably about 0.25 to 0.6%, and optimally, about 0.35 to 0.6%.

Cosmetic compositions containing strongly swellable, moderately

What is provided herein are skin care compositions containing discrete microdroplets of an oil in water stabilized by in situ polymerization of a water-soluble vinyl monomer. The discrete microdroplets are prepared by dispersing the oil, preferably a silicone, in water, adding the water-soluble vinyl monomer, preferably vinylpyrrolidone, and polymerizing the monomer in situ such that the oil is stabilized in the resulting polymer solution as discrete microdroplets.

Skin care compositions containing discrete microdroplets of an oil in

What is provided herein is a method for treating acne vulgaris with a composition containing a stable, high purity, substantially anhydrous complex of PVP and H.sub.2 O.sub.2 in which the constituents are present respectively in substantially a 1:1 molar ratio and the complex is a free-flowing, fine white powder.

Method for treating acne vulgaris with a composition containing a

The hair setting shampoo composition of the invention comprises a resin provided by about 1-15% by weight of about a 20-50% resin active alcoholic solution of the alkyl half-ester of a C.sub.1 -C.sub.5 alkyl vinyl ether-maleic anhydride copolymer having a molecular weight of at least one million, which is about 5-90% neutralized, preferably with about 0.01-1% by weight of 2-amino-2-methyl-1-propanol, about 5-60% by weight of a surfactant, optionally 0-10% by weight of added ethanol, and about 30-90% by weight of water. The composition provides a subtle temporary set on hair of the user without the use of auxiliary fixatives in the composition.

Hair setting shampoo composition

The invention relates primarily to quaternized polycyclic compounds having the formula ##STR1## wherein m is an integer having a value of from 1 to 4; R is alkylene having from 3 to 8 carbon atoms and is optionally substituted with C.sub.1 to C.sub.4 alkyl; R.sub.2 together with the quaternary nitrogen, forms a 5 to 14 membered heterocyclic ring, said ring containing at least 2 hetero atoms selected from the group of nitrogen, sulfur and oxygen; R.sub.1 forms a double bond in the heterocyclic ring of the quaternized nitrogen or is alkyl, alkyleneoxyalkyl, alkylhydroxy, aryl, aralkyl, aralkenyl, alkaryl, alkylamidoalkyl and X.sup.- is an anion. The invention also relates to the preparation and use of said quaternized polycyclic compounds.
