Patent ID: RE39557

Claim:
A detergent composition comprising: a) from about 1% to about 80% by weight of surfactants selected from the group consisting of nonionic, anionic, cationic, amphoteric, zwitterionic surfactants, or mixtures thereof; and b) from about 0.1% to about 5.0% by weight of a mixture of cellulosic based polymers or oligomers of the general formula: wherein each R is selected from the group consisting of R C , and H; wherein: each R C is wherein each Z is independently selected from the group consisting of M, R 2 ,R C , and R H ; each R 2 is independently selected from the group consisting of H and C 1 -C 4 alkyl; each R H is independently selected from the group consisting of C 5 -C 20 alkyl, C 5 -C 7 cycloalkyl, C 7 -C 20 alkylaryl, C 7 -C 20 arylalkyl, substituted alkyl, hydroxyalkyl, C 1 -C 20 alkoxy-2-hydroxyalkyl, C 7 -C 20 alkylaryloxy-2-hydroxyalkyl, (R 4 ) 2 N-alkyl, (R 4 ) 2 N-2-hydroxyalkyl, C 6 -C 12 aryloxy-2-hydroxyalkyl, each R 4 is independently selected from the group consisting of H, C 1 -C 20 alkyl, C 5 -C 7 cycloalkyl, C 7 -C 20 alkylaryl, C 7 -C 20 arylalkyl, aminoalkyl, alkylaminoalkyl, dialkylaminoalkyl, piperidinoalkyl, morpholinoalkyl, cycloalkylaminoalkyl and hydroxyalkyl; each R 5 is independently selected from the group consisting of H, C 1 -C 20 alkyl, C 5 -C 7 cycloalkyl, C 7 -C 20 alkylaryl, C 7 -C 20 arylalkyl, substituted alkyl, hydroxyalkyl, (R 4 ) 2 N-alkyl, and (R 4 ) 3 N-alkyl; wherein: M is a suitable cation selected from the group consisting of Na, K, 1/2 Ca, and 1/2 Mg; each y is from about 1 to about 5; and provided that: the Degree of Substitution for group R H is between about 0.001 and 0. 1; the Degree of Substitution for group R C wherein Z is H or M is between about 0.2 and 2.0; if any R H bears a positive charge, it is balanced by a suitable anion; and two R 4 's on the same nitrogen can together form a ring structure selected from the group consisting of piperidine and morpholine.
