Patent ID: 7393815

Claim:
An oil containing starch granule comprising: (a) a starch, said starch being present in an amount to form an effective matrix for said granule; (b) an oil, said oil being capable of providing a benefit-additive to a substrate upon contact therewith; and (c) an effective amount of an organic compound comprising 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 alkyleneoxvaryl; or (i) C 7 -C 22 oxvalkylenearyl; or (j) an anionic unit having the formula: —(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; 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.
