Abstract

The invention concerns a perfume composition comprising a perfume base and a lipophilic solubilizing agent based on at least an organopolysiloxane having according to Hansen solubility parameter the following characteristics: &dgr;D London interactions ranging from (8) to (21) (J/cm3)½, &dgr;P of Keesom interactions greater than 0 and capable of reaching 25 (J/cm3)½, &dgr;H of hydrogen binding ranging from (0) to (23) (J/cm3)½. Said organotrisiloxanes with polar or polarizsable function of formula (I) are used as solubilizing agents and emollients in perfume composition.
