Abstract
The invention relates to an additive comprising at least 95 wt. % of a mixture consisting of at least one organic filter filtering UVA, at least one organic filter filtering UVB, and from 1 to 50 wt. % of at least one non-volatile oil that is a solvent for said filters. This composition is particularly useful as an agent for protecting the organoleptic properties of a transparent cosmetic composition, against UV radiation.
