Abstract
Cosmetic oil-in-water emulsions that can provide a hydrophobic film to protect from excessive hydration are disclosed. In some aspects, a cosmetic oil-in-water emulsion can include water at a concentration of at least about 70% by total weight of the cosmetic oil-in-water emulsion, a plurality of water-in-oil emulsifiers, a base oil, an oil-in-water emulsifier, and a film-forming polymer. The base oil can have a wVTR of about 1.0 to 30 g/m2/hr and can be at a concentration of no more than about 15% by weight of the cosmetic oil-in water emulsion.
