Contact allergy to 4‐isopropyl dibenzoylmethane and 3‐(4′‐methylbenzylidene) camphor in the sunscreen Eusolex 8021

Abstract
10 cases of contact allergy from the sunscreen Eusolex 8021 are reported. 5 patients were sensitized to a lipstick, 4 to a sunscreen cream, and 1 reacted to several cosmetic creams. Of 9 patients tested with the 2 ingredients of Eusolex 8021, 5 proved to be allergic to both (chemically unrelated) constituents: 4-isopropyl-dibenzoylmethane and 3-(4'-methylbenzylidene) camphor; 4 were allergic to 4-isopropyl-dibenzoylmethane only. Contact allergy to this recently introduced broad spectrum sunscreen may not be rare. The relevant literature is reviewed.
