An anti-solar cosmetic composition contains as the anti-solar agent a compound of the formula ##STR1## wherein R represents a member selected from the group consisting of hydrogen, a halogen selected from the group consisting of chlorine and fluorine and alkyl containing 1-4 carbon atoms; R' and R" each independently represent a member selected from the group consisting of hydrogen and SO.sub.3 M wherein M represents a member selected from the group consisting of hydrogen, organic ammonium group and a metal, wherein at least one of R' and R" is other than hydrogen, and R" is a substituent at the para or meta position relative to the bornylidene ring. The anti-solar agent is present in amounts of 0.5-10 percent by weight of said composition.

alkyl radical; with the proviso that the sum of p+t is between 3 and 20, in a composition comprising, in a cosmetically acceptable medium, at least one liquid fatty phase and at least one lipophilic active agent, and containing no dibenzoylmethane-type UV screening agent, as a solvent for said active agent in said liquid fatty phase and/or as an agent improving the solubility of said active agent in the solid fatty phase. The present invention also relates to a composition comprising, in a cosmetically acceptable medium, at least one liquid fatty phase, characterized in that it comprises at least one caprolactam derivative of formula (I) as defined above and in that it does not contain a dibenzoylmethane-type UV screening agent.
