Oil containing starch granules for delivering benefit-additives to a substrate

摘要

An oil containing starch granule comprising:
(a) a starch, said starch forming a matrix for said granule;
(b) a perfume oil comprising ingredients having a calculated Clog P of at least 3, said Clog P being the calculated octanol to water partition coefficient, said perfume oil being capable of providing a benefit-additive to a substrate upon contact therewith, said substrate being selected from the group consisting of fabrics, hard surfaces, hair and skin; and
(c) an effective amount of a quaternary ammonium compound for inhibiting the migration of said oil to the surface of said starch granule, said compound being represented by the following structure:
wherein R 1 and R 2 are each independently, H or:
(a) C 1 -C 22 alkylenecarboxy moiety having the formula:
-(CH 2 ) e R 3 wherein R 3 is -NHCOR 4 ; or -OCOR 4 ; or -NR 5 COR 4 ; and wherein R 4 and R 5 are each independently C 1 -C 22 akyl or alkenyl; and e is an integer from 1 to 22; or
(b) C 1 -C 22 linear or branched alkyl; or
(c) C 1 -C 22 linear or branched alkenyl; or
(d) C 2 -C 22 substituted or unsubstituted alkylenoxy; or
(e) C 3 -C 22 substituted or unsubstituted alkylenoxy alkyl; or
(f) C 6 -C 22 substituted or unsubstituted aryloxy; or
(g) C 7 -C 22 substituted or unsubstituted alkylenearyl; or
(h) C 7 -C 22 substituted or unsubstituted alkyleneoxyaryl; or
(i) C 7 -C 22 oxyalkylenearyl; or
(j) an anionic unit having the formula:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ- (CH 2 ) y R 6
wherein R 6 is -SO 3 M, -OSO 3 M, -PO 3 M, -OPO 3 M, Cl or mixtures thereof, wherein M is hydrogen, or one or more salt forming cations sufficient to satisfy charge balance, or mixtures thereof; R 6 may also be choloride; y is an integer from 1 to about 22; and
(k) a mixture comprising at least two of (a) through (j); and
q is an integer from 0 to about 22; m is an integer from 0 to about 22; Q is (CH 2 ) m or (CH 2 CHR 7 O); R 7 is independently hydrogen, methyl, ethyl, propyl or benzyl; and mixtures thereof; B is H or OH; Y is N; R 8 is H or C 1 -C 4 alkyl,; Z - is a counter anion, and preferably chloride,or methyl sulfate.
