Abstract
The present invention relates to compositions comprising: (a) at least two phenolic compounds (one flavoid and one non-flavoid); (b) at least one hydrotrope; (c) at least one emulsifier; (d) a lipid-soluble antioxidant; and (e) water. The at least one hydrotrope should be present in an amount that is effective to solubilize said at least two phenolic compounds in the water phase of the composition. The at least one emulsifier should be present in an amount sufficient to create a water-in-oil or oil-in-water emulsion that is effective to solubilize the lipid-soluble antioxidant. The compositions are useful for cosmetic purposes and other uses.
