摘要

The invention relates to a high SPF/UVAPF sunscreen composition. It is an object of the present invention to provide an SPF of at least 10 and a UVAPF of at least 2. This is achieved by inclusion of a select emollient in a sunscreen containing composition comprising a cosmetically acceptable base comprising volatile silicone and silicone elastomer.
