A nail lacquer for the treatment or prevention of fungal infections, such as, onychomycosis, includes fungicidally effective amount of ciclopirox, econazole, or other antifungal agent in a compatible film-forming lacquer vehicle which includes a water-insoluble film-forming polymer; pentadecalactone, or similar cyclic lactone compound or derivative thereof, and volatile solvent. The pentadecalactone functions as a plasticizer for the film-forming polymer and as a penetration enhancer for the antifungal agent. The composition, when applied to the nails provides a hard, clear, water-resistant film containing the antifungal agent. The compositions are used for the treatment of onychomycosis.
A silicone composition containing a polyethersiloxane block copolymer network and a fluid within the network is useful as a component of various personal care compositions.
