Abstract
A water-releasing photoprotection composition in the form of an emulsion and process for preparing the photoprotection composition are provided. The photoprotection composition includes an aqueous phase and an oil phase. The aqueous phase includes at least one water-soluble UV filter. The oil phase includes dimethicone and an emulsifying crosslinked siloxane elastomer. The photoprotection composition has a phase ratio of the aqueous phase to the oil phase of from about 3 to about 12. The photoprotection composition converts from an emulsion to a plurality of droplets upon application of shear.
