ABSTRACT:
The novel 4-(1,1-Dimethylethyl)-4'-methoxydibenzoylmethane is useful as a sunscreen agent. It exhibits outstanding UV-A absorbing qualities in that it brings about a considerable retardation in the ageing of the skin with excellent skin tolerance and stability (light, heat and moisture).
4-(1,1-Dimethylethyl)-4'-methoxydibenzoylmethane furthermore improves the protective action of UV B-filters, i.e. of substances which absorb the erythema-producing UV B-radiation in the range of about 290 to 320 mm.
