A composition for application to skin comprising: (i) at least 40wt% ethanol, (ii) from 0.1 to 6 wt% perfume comprising non-polar perfume materials, (iii) optionally, at least 0.2 wt% surfactant, (iv) 0.1 to 6 wt% of porous microparticles comprising sol-gel derived material, the sol-gel derived material including a plurality of alkylsiloxy substituents and wherein the sol-gel derived material is obtained from: (a) at least one first alkoxysilane precursor having the formula: (R'O)3-Si-(CH2)n-Ar-(CH2)m-Si-(OR')3 (1) where n and m are individually an integer from 1 to 8, Ar is a single-, fused-, or poly- aromatic ring, and each R' is independently a C1 to C5 alkyl group and (b) optionally, at least one second precursor having the formula: (2) where x is 1, 2, 3 or 4； y is 0, 1, 2, 3； z is 0, 1； the total of x + y + z is 4； each R is independently an organic functional group； each an R' is independently a C1 to C5 alkyl group and R'' is an organic bridging group, where the sol-gel derived material is swellable to at least 2.5 times its dry mass, when placed in excess acetone, whereby at least part of the perfume remains outside the microparticles. Also, a method of prolongation of perfume delivery from a perfumed composition comprising the steps of: (i) adding sol–gel derived silica microparticles as described above to an ethanolic composition comprising ethanol and perfume, comprising non-polar perfume components, dispersed or dissolved in the ethanol, and optionally surfactant； (ii) applying the composition to skin to deposit the microparticles onto the skin (iii) evaporating the ethanol to leave some perfume and the microparticles on the skin； absorbing at least part of the non-polar perfume components from the liquid into the microparticles, preferably such that the microparticles increase in weight by 20 to 80 wt%, and (iv) releasing perfume from the microparticles over a period of from up to 24 hours.L'invention concerne une composition destinée à être appliquée
