A photoprotective composition includes one or more photoactive agents (such as a UV filter compound), one or more optimizing agents, and a copolymer booster. Such a composition provides an unexpected synergistic combination of the one or more optimizing agents and the copolymer booster for increasing at least one of SPF, UVA/UVB ratio, critical wavelength, photostability of UVA absorber and PFA, and any combinations thereof, of the composition.
L'invention porte sur une composition photoprotectrice qui comprend un ou plusieurs agents photoactifs (tels qu'un composé de filtre UV), un ou plusieurs agents optimisants et un amplificateur copolymère. Une telle composition offre une combinaison synergique inattendue du ou des agents optimisants et du copolymère amplificateur pour augmenter au moins l'un parmi SPF, le rapport UVA/UVB, une longueur d'onde critique, la photostabilité d'un agent absorbant le rayonnement UVA et les PFA, et toutes combinaisons de ceux-ci, de la composition.
