Photoprotection composition containing high levels of water-soluble UV filters

摘要

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.

1. A composition comprising:
(a) an aqueous phase containing at least one water-soluble UV sunscreen filter; and (b) an oil phase consisting of:
(i) dimethicone, at a concentration by weight of from about 1% to about 25%, based upon weight of the composition; and(ii) an emulsifying crosslinked siloxane elastomer at a concentration, by weight, of about 0.5% to about 7%, based upon weight of the composition;wherein a phase ratio of the aqueous phase to the oil phase is from about 3.0 to about 12.0; and wherein the composition converts from an emulsion to a plurality of droplets upon application of shear.
