Abstract
The instant disclosure is drawn to a cosmetic or personal care composition comprising: (a) hydrophobic polymer formed as a reaction product of a natural or food-derived oil and a methacrylate or acrylate polymer; (b) one or more solvents capable of solubilizing the hydrophobic polymer; (c) one or more surfactants; and (d) water. The cosmetic or personal care composition is preferably in the form of an oil-in-water emulsion. Methods for making and using the compositions are also disclosed.

A cosmetic composition comprising:
- (a) a hydrophobic polymer formed as a reaction product of a natural or food-derived oil and a methacrylate or acrylate polymer;
- (b) one or more solvents capable of solubilizing the hydrophobic polymer of (a);
- (c) one or more surfactants;
- and
- (d) water;
- wherein the composition is an oil-in-water emulsion.
A composition comprising:
- (a) about 10 to about 40 wt. % of a hydrophobic polymer formed as a reaction product of a natural or food-derived oil and a methacrylate or acrylate polymer;
- (b) about 1 to about 15 wt. % of one or more solvents capable of solubilizing the hydrophobic polymer of (a);
- (c) about 20 to about 60 wt. % of a plurality of surfactants, wherein the plurality of surfactants comprises:
- (c)(i) about 15 to about 30 wt. % one or more biosurfactants;
- and
- (c)(ii) about 5 to about 20 wt. % one or more surfactants other than (c)(i);
- (d) about 10 to about 50 wt. % of water;
- wherein all percentages by weight are based on a total weight of the composition.
A cosmetic composition comprising:
- (a) about 0.5 to about 10 wt. % of a hydrophobic polymer formed as a reaction product of a natural or food-derived oil and a methacrylate or acrylate polymer;
- (b) about 0.1 to about 50 wt. % of one or more solvents capable of solubilizing the hydrophobic polymer of (a);
- (c) about 0.5 to about 10 wt. % of a plurality of surfactants;
- and
- (f) about 50 to about 95 wt. % of water;
- wherein the composition is an oil-in-water emulsion, and all percentages by weight are based on a total weight of the composition.
A method for making a cosmetic composition comprising:
- (i) forming an initial composition comprising:
- (a) about 10 to about 40 wt. % of a reaction product of a natural or food-derived oil and a methacrylate or acrylate polymer;
- (b) about 1 to about 30 wt. % one or more solvents capable of solubilizing the reaction product of (a);
- (c) about 20 to about 60 wt. % of a plurality of surfactants;
- and
- (d) about 10 to about 40 wt. % of water;
- (ii) diluting the initial composition with water to form the cosmetic composition in the form of an oil-in-water emulsion.
