Abstract
The present invention relates to leave on, skin care compositions, comprising: (a) from about 0.1% to about 30% of a sunscreen active, (b) from about 0.5% to about 20% of a hydrophobic, structuring agent, (c) from about 0.2% to about 10% of a hydrophilic surfactant, (d) from about 0.1% to about 5% of a thickening agent, (e) from about 0.1% to about 25% of a skin lightening agent and (f) water. These compositions are useful for providing (i) protection to human skin from the harmful effects of ultraviolet radiation and (ii) a skin lightening benefit.
Claims21
A photoprotective composition comprising:
- (a) from about 0.1% to about 30% of a sunscreen active;
- (b) from about 0.5% to about 20% of a hydrophobic, structuring agent selected from the group consisting of saturated C.sub.16 to C.sub.30 fatty alcohols, saturated C.sub.16 to C.sub.30 fatty alcohols containing from about 1 to about 5 moles of ethylene oxide, saturated C.sub.16 to C.sub.30 diols, saturated C.sub.16 to C.sub.30 monoglycerol ethers, saturated C.sub.16 to C.sub.30 hydroxy fatty acids, and mixtures thereof, having a melting point of at least about 40.degree. C.;
- (c) from about 0.2% to about 10% of a hydrophilic surfactant selected from the group consisting of nonionic surfactants, anionic surfactants, cationic surfactants, zwitterionic surfactants, amphoteric surfactants, and mixtures thereof;
- (d) from about 0.1% to about 5% of a thickening agent selected from the group consisting of carboxylic acid polymers, crosslinked polyacrylate polymers, polyacrylamide polymers, polysaccharides, gums, crosslinked vinyl ether/maleic anhydride copolymers, crosslinked poly(N-vinylpyrrolidones), and mixtures thereof;
- (e) from about 0.001% to about 25% of a skin lightening agent;
- and
- (f) from about 25% to about 99.1% water.
