Abstract
There are described personal care compositions containing a) one or more dibenzoylmethane sunscreening agents; and b) a photostablising amount of a salicylate ester of formula (1): (2-OH)Ph-(CO)—O—R, wherein R represents an alkyl group consisting of a chain of from 7 to 16 carbon atoms substituted by at least one group selected from methyl and ethyl. The compound of formula (1) is preferably isodecyl salicylate or isotridecyl salicylate. The salicylate esters of formula (1) have a stabilizing effect on the compositions. The salicylate esters prevent or inhibit degradation of the sunscreening agents which would otherwise lead to a reduction in the efficacy of the sunscreening agents and an increase in the deleterious effects of exposure to sunlight on the user of the compositions or on the compositions themselves.
