Abstract:
A detergent composition or component comprising a dry-added particulate hydrophobically modified cellulosic material, wherein at least 80% of said particulate material has a particle size of below 1000 microns, said material comprising polymers of the formula wherein each R is selected from the group consisting of R2, RC, and wherein:each R2 is independently selected from the group consisting of H and C1-C4 alkyl; each RC wherein each Z is independently selected from the group consisting of M, R2, RC, and RH;each RH is independently selected from the group consisting of C5-C20 alkyl, C5-C7 cycloalkyl, C7-C20 alkylaryl, C7-C20 arylalkyl, substituted alkyl, hydroxyalkyl, C1-C20 alkoxy-2-hydroxyalkyl, C7-C20 alkylaryloxy-2-hydroxyalkyl, (R4)2N-alkyl, (R4)2N-2-hydroxyalkyl, (R4)3 N-alkyl, (R4)3 N-2-hydroxyalkyl, C6-C12 aryloxy-2-hydroxyalkyl, each R4 is independently selected from the group consisting of H, C1-C20 alkyl, C5-C7 cycloalkyl, C7-C20 alkylaryl, C7-C20 arylalkyl, aminoalkyl, alkylaminoalkyl, dialkylaminoalkyl, piperidinoalkyl, morpholinoalkyl, cycloalkylaminoalkyl and hydroxyalkyl; each R5 is independently selected from the group consisting of H, C1-C20 alkyl, C5-C7 cycloalkyl, C7-C20 alkylaryl, C7-C20 arylalkyl, substituted alkyl, hydroxyalkyl, (R4)2N-aklyl, and (R4)3 N-alkyl; wherein:M is a suitable cation; each x is from 0 to about 5; each y is from about 1 to about 5; and provided that:the Degree of Substitution for group RH is between about 0.001 and 0.1; the Degree of Substitution for group RC wherein Z is H or M is between about 0.2 and 2.0; if any RH bears a positive charge, it is balanced by a suitable anion; and two R4's on the same nitrogen can together form a ring-structure selected from the group consisting of piperidine and morpholine, said particulate cellulosic material further comprising a binder selected from the group consisting of polyacrylate and maleic/acrylic acid copolymer.
