A dispersion or suspension of lecithin or of a sorbitan ester or of sorbitol in a propellant of dichlorodifluoromethane is free of trichloromonofluoromethane propellant. The surfactants are used in pressurised packaged compsns. particularly finely divided medicaments. The surfactants form stable dispersions in the propellant, avoiding the use of propellant which has certain undesirable properties. The compsn. pref. contains less than 0.2-2% surfactant. It pref. contains a finely divided medicament, esp. of dia. 0.01-10 mu, in an amt. of 1-5%.
