Abstract
A water-releasing sunscreen composition in the form of an emulsion and process for using the composition are provided. The composition includes an aqueous phase containing at least one water-soluble ingredient. The composition further includes an oil phase containing a first emulsifier and a liquid organic liposoluble UV filter. The liquid organic liposoluble UV filter is at a concentration from about 10% to about 25%. The composition includes a phase ratio of the aqueous phase to the oil phase of about 1.0 to about 12.0. The sunscreen composition is stable, has a sun protection factor (SPF) of greater than or equal to 15 and converts from an emulsion to a plurality of droplets upon application of shear.
