摘要
A delivery system for applying an active material to the skin comprises a film on which is a composition containing a salicylic acid derivative (I), this composition being free from particulate water-soluble active components. A delivery system for applying an active material to the skin comprises a film on which is a composition containing a salicylic acid derivative of formula (I), this composition being free from particulate water-soluble active components. R = 3-11C saturated (cyclo)aliphatic, or 3-17C unsaturated aliphatic having one or more ethylenic unsaturations optionally conjugated (all optionally substituted by one or more halo, trifluoromethyl and optionally esterified by a 1-6C acid or a carboxyl that may be esterified by a 1-6C alcohol); and R' = OH or 2-16C (un)saturated ester.
