Abstract

The invention provides polymers comprising repeating units derived from (a) from 16% by weight to about 35% by weight of said polymer of at least one N-vinyl lactam monomer; (b) at least one monomer selected from the group consisting of functionalized and unfunctionalized C 1 -C 6 alkyl (meth)acrylates, C 1 -C 6 alkyl (meth)acrylamides and combinations thereof; and (c) at least one monomer selected from the group consisting of functionalized and unfunctionalized C 8 -C 30 branched alkyl (meth)acrylates, C 8 -C 30 branched alkyl (meth)acrylamides, and combinations thereof; wherein the polymer has a glass transition temperature of greater than about 45° C. The invention further provides various compositions, such as, personal care, sun care, coatings, and pharmaceutical compositions comprising the polymers described herein. The invention furthermore provides water-resistant sun care compositions comprising the polymers described herein. Subscripts x, y and z are described herein. (Formula (I))

First claim

What is claimed is:

1. A personal care composition comprising a polymer comprising repeating units derived from:
(a) from 16% by weight to about 35% by weight of said polymer of at least one N-vinyl lactam monomer;
(b) at least one monomer selected from the group consisting of functionalized and unfunctionalized C 1 -C 6 alkyl (meth)acrylates, C 1 -C 6 alkyl (meth)acrylamides and combinations thereof; and
(c) at least one monomer selected from the group consisting of functionalized and unfunctionalized C 8 -C 30 branched alkyl (meth)acrylates, C 8 -C 30 branched alkyl (meth)acrylamides, and combinations thereof; wherein said polymer has a glass transition temperature of greater than about 45° C.

2. The personal care composition according to claim 1 wherein said personal care composition is a sun care composition, a face care composition, a lip care composition, an eye care composition, a skin care composition, an after-sun composition, a body care composition, a nail care composition, an anti-aging composition, an insect repellant, an oral care composition, a deodorant composition, a hair care composition, a conditioning composition, a color cosmetic composition, a color-protection composition, a self-tanning composition, or a foot care composition.

3. The personal care composition according to claim 2 wherein said personal care composition is a sun care composition.

4. The personal care composition according to claim 3 wherein said sun care composition is a water-resistant sun care composition.

5. The personal care composition according to claim 4 wherein said water-resistant sun care composition further comprises at least one UV active.

6. The personal care composition according to claim 5 wherein said water-resistant sun care composition further comprises at least one additive selected from the group consisting of secondary polymers for improving water-resistance, UV active solubilizers, oils, waxes, solvents, emulsifiers, preservatives, antioxidants, antiradical protecting agents, vitamins, perfumes, insect repellants, dyes, pigments, humectants, fillers, thickeners, film formers, stabilizers, buffers, spreading agents, pearlizing agents, electrolytes, acids, bases, pharmaceutically or dermatologically or cosmetically acceptable excipients, and combinations thereof.

7. The personal care composition according to claim 4 wherein said water-resistant sun care composition is in the form of an oil-in-water emulsion, a water-in-oil emulsion, an oil-water-oil emulsion, a water-oil-water emulsion, a water-in-silicone emulsion, an oily solution, a lipid fusion, a hydro-alcoholic gel, an anhydrous formulation, an anhydrous gel, an aqueous gel, an alcoholic solution or a hydro-alcoholic solution.

8. A method for protecting a keratinous substrate from UV radiation comprising applying onto said substrate a water resistant sun care composition comprising:
(a) a polymer comprising repeating units derived from: from 16% by weight to about 35% by weight of said polymer of at least one N-vinyl lactam monomer; at least one monomer selected from the group consisting of functionalized and unfunctionalized C 1 -C 6 alkyl (meth)acrylates, C 1 -C 6 alkyl (meth)acrylamides and combinations thereof; and at least one monomer selected from the group consisting of functionalized and unfunctionalized C 8 -C 30 branched alkyl (meth)acrylates, C 8 -C 30 branched alkyl (meth)acrylamides, and combinations thereof, wherein said polymer has a glass transition temperature of greater than about 45° C.; and
(b) at least one UV active.
