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

摘要

An oil containing starch granule is provided comprising: (a) a starch to form an effective 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 an organic compound for inhibiting the migration of said oil to the surface of said starch granule, said compound being represented by the following structure: wherein R₁ and R₂ are each independently, H or: (a) C₁-C₂₂ alkylenecarboxy moiety having the formula -(CH₂)_eR₃ wherein R₃ is -NHCOR₄; or -COR₄; or -NR₅COR₄; and wherein R₄ and R₅ are each independently C₁-C₂₂ alkyl or alkenyl; and e is an integer from 1 to 22; or (b) C₁-C₂₂ linear or branched alkyl; or (c) C₁-C₂₂ linear or branched alkenyl; or (d) C₂-C₂₂ substituted or unsubstituted alkylenoxy; or (e) C₃-C₂₂ substituted or unsubstituted alkylenoxy alkyl; or (f) C₆-C₂₂ substituted or unsubstituted aryloxy; or (g) C₇-C₂₂ substituted or unsubstituted alkylenearyl; or (h) C₇-C₂₂ substituted or unsubstituted alkyleneoxyaryl; or (i) C₇-C₂₂ oxyalkylenearyl; or (j) an anionic unit having the formula: -(CH₂)_yR₆ wherein R₆ is -SO₃M, -OSO₃M, -PO₃M, -OPO₃M, Cl or mixtures thereof, wherein M is hydrogen, or one or more salt forming cations sufficient to satisfy charge balance, or mixtures thereof; y is an integer from 1 to about 22; or (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 (CH₂)_m or (CH₂CHR₇O); R₇ is independently hydrogen, methyl, ethyl, propyl or benzyl; B is H or OH; and Y is CR₁ or N.
