| abstract |
The invention concerns a perfume composition comprising a perfume base and a lipophilic solubilising agent based on at least an organopolysiloxanes of formula (I): (R<1>)(R<2>)(R<3>)Si-O-[Si(R<4>)(Z)-O] n-[Si(R<5>)(R<6>)-O]m-Si(R<7>)(R<8>)(R<9>) or (I') in which: the symbols R<1> and R<9> are identical or different and represent the symbol Z or a (C1-C8) alkyl radical; the symobls R<2>, R<3>, R<4>, R<5>, R<6>, R<7> and R<8> are identical or different and represent a (C1-C8) alkyl radical; the symbol Z represents a polar or polarisable organic radical; in formula (I) <u>m</u> ranges between (0) and (5) and n between (0) and (5), at least one of the radicals R<1> and R<9> representing the symbol Z when <u>n</u> is equal to (0); in formula (I') <u>n</u> ranges between (1) and (5), and <u>m</u> between (1) and (5), with <u>n</u>+<u>m</u> equal to at least (3); said organopolysiloxanes having according to Hansen solubility parameter the following characteristics: delta D London interactions ranging from (8) to (21) (J/cm<3>)<1/2>, delta P of Keesom interactions greater than (0) and capable of reaching 25(J/cm<3>)<1/2>; delta H of hydrogen binding ranging between (0) to (23) (J/cm<3>)<1/2>. Said organotrisiloxanes with polar or polarisable function of formula (I) are used as solubilising agents and emollients in perfume compositions. |
