Claims18
A silicone compound comprising a silicone moiety and a benefit agent moiety,
- wherein said benefit agent moiety is a fragment of a benefit agent selected from the group consisting of perfume raw materials, and wherein said benefit agent comprises a moiety selected from the group consisting of a ketone, aldehyde, and mixtures thereof;
- wherein said silicone compound has the formula:
- [R1R2R3SiO1/2](j+2l+2)[R4R5SiO2/2]m[R6SiO3/2]j[SiO4/2]l
- wherein:
- a) j is an integer from 0 to 150;
- b) m is an integer from 0 to 1500;
- c) l is an integer from 0 to 150;
- with the provisio j+m+l equals an integer greater than or equal to 1, and at least one of the moieties R1 through R6═X—Z;
- d) each of R1, R2, R3, R4, R5 and R6 moiety is independently selected from the group consisting of H, OH, C1-C32 alkyl, C1-C32 substituted alkyl, C6-C32 aryl, C5-C32 substituted aryl, C6-C32 alkylaryl, C6-C32 substituted alkylaryl, C1-C32 alkoxy and C1-C32 substituted alkoxy and X—Z;
- (i) each X is independently oxygen or a substituted or unsubstituted divalent alkylene radical comprising 2-12 carbon atoms;
- (ii) each Z is selected independently from the group consisting of:
- each R7 is independently selected from the group consisting of H, C1-C32 alkyl, C1-C32 substituted alkyl, C6-C32 aryl, C5-C32 substituted aryl, C6-C32 alkylaryl, C5-C32 substituted alkylaryl;
- and
- each R8 is independently selected from the group consisting of C1-C32 alkyl, C1-C32 substituted alkyl, C6-C32 aryl, C5-C32 substituted aryl, C6-C32 alkylaryl, and C5-C32 substituted alkylaryl.
