Abstract
A multiphase cleansing composition is disclosed, useful for cleansing the skin or hair, for example, for removing makeup from the skin or hair. The multiphase cleansing composition comprises an oil phase and an aqueous phase. The oil phase comprises: (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). The aqueous phase comprises water and optionally one or more water soluble solvents and one or more electrolytes. Methods of cleansing skin and hair are also described.

A multiphase cleansing composition comprising:
- (i) an oil phase comprising:
- (a) a hydrophobic polymer formed by reacting about 72 to about 77 parts by weight of a natural or food-derived oil and about 23 to about 28 parts by weight of a methacrylate or acrylate polymer;
- (b) one or more solvents capable of solubilizing the hydrophobic polymer;
- (ii) an aqueous phase comprising:
- (a) water.
A multiphase cleansing comprising:
- (i) about 20 to about 50 wt. % of an oil phase comprising:
- (a) about 0.01 to about 2 wt. % of a hydrophobic polymer formed by reacting about 72 to about 77 parts by weight of linseed oil and about 23 to about 28 parts by weight of isobutyl methacrylate polymer;
- (b) about 5 to about 50 wt. % of one or more solvents capable of solubilizing the hydrophobic polymer having a dispersion component (D), a polar component (P), and a hydrogen bonding component (H), and a distance (Ra) per Hansen Solubility Parameters of less than or equal to 13.4 MPa0.5, wherein the distance (Ra) is defined by formula (I):
