The present invention relates to low pH topical sunscreen compositions which utilize unneutralized, 2-phenylbenzimidazole-5-sulfonic acid as the sunscreen active. These compositions exhibit good sunscreening efficacy and are highly substantive to the skin.

Low pH sunscreen compositions

The present invention relates to oil-in-water emulsion compositions useful for topical application to human skin. These compositions comprise from about 5% to about 60% by weight of the total composition of an oil phase having a viscosity from about 3000 cps to about 10,000,000 cps, wherein the oil phase comprises from about 0.1% to about 10% by weight of the total composition of a particulate thickener for the oil phase, and from 0% to about 10% by weight of the total composition of an oil phase emulsifier. These compositions also comprise from about 40% to about 95% by weight of the total composition of an aqueous phase selected from the group consisting of water, water-miscible solvents, and mixtures thereof, wherein the aqueous phase comprises from 0% to about 10% by weight of the total composition of an aqueous phase emulsifier. In these compositions the weight percentages of the oil phase emulsifier and of the aqueous phase emulsifer are not simultaneously zero.

Emulsion compositions

Bar soaps containing polyhydroxy fatty acid amides exhibit good 'smear' qualities, desirable hardness and good lather properties. The bars also have a decreased tendency to crack. Bars comprising soap and materials such as C.sub.12 -C.sub.18 N-methyl glucamide are provided.
