Abstract
Consumer product compositions providing enhanced hydrophobic benefit agent deposition. The benefit agent is provided as a benefit agent/deposition aid emulsion, where the benefit agent is physically adsorbed to the deposition aid before the emulsion is added to the balance of ingredients.
Claims19
A benefit agent emulsion comprising a benefit agent and a cationic deposition aid, wherein said cationic deposition aid comprises a pendant organopolysiloxane having the formula:
- [R1R2R3SiO1/2](j+2)[(R4Si(X—K)O2/2]k[R4R4SiO2/2]m[R4SiO3/2]j
- wherein:
- j is an integer from 0 to about 98;
- k is an integer from 1 to about 200;
- m is an integer from 4 to about 5,000;
- R1, R2 and R3 are each independently selected from the group consisting of H, OH, C1-C32 alkyl, C1-C32 substituted alkyl, C5-C32 or C6-C32 aryl, C5-C32 or C6-C32 substituted aryl, C6-C32 alkylaryl, C6-C32 substituted alkylaryl, C1-C32 alkoxy, C1-C32 substituted alkoxy and X—K;
- each R4 is independently selected from the group consisting of H, OH, C1-C32 alkyl, C1-C32 substituted alkyl, C5-C32 or C6-C32 aryl, C5-C32 or C6-C32 substituted aryl, C6-C32 alkylaryl, C6-C32 substituted alkylaryl, C1-C32 alkoxy and C1-C32 substituted alkoxy;
- for each X—K X comprises a divalent alkylene radical comprising 2-12 carbon atoms, each divalent alkylene radical is independently selected from the group consisting of —(CH2)s— wherein s is an integer from 2 to 8;
- and
- each K is selected independently from the group consisting of:
- each Q is independently a H or a C1-C32, linear or branched, substituted or unsubstituted hydrocarbon, with the proviso that when K is a quat, Q cannot be an amide, imine, or urea moiety and if Q is an amide, imine, or urea moiety, then any additional Q bonded to the same nitrogen as said amide, imine, or urea moiety must be H or a C1-C6 alkyl;
- X is defined as above;
- for K An− is a suitable charge balancing anion;
- wherein the pendant organopolysiloxane and the benefit agent are different relative to each other, and wherein the pendant organopolysiloxane is adsorbed onto the benefit agent.
