Patent ID: 7179777

Claim:
A laundry treatment composition comprising at least one polymeric material comprising a cationic polymer moiety and a polydialkylsiloxane moiety, and at least one other component, wherein the polymeric material is incorporated in the form of an emulsion with a silicone and wherein the polymeric material has a formula selected from: (A-b-B) n -A (A-b-B) n A-g-(B) n (A-r-B) n (B-b-A) n -B (B-b-A) n B-g-(A) n wherein: A is a moiety that contains one or more cationic monomer units, preferably comprising from 5% to 100% by weight of cationic monomer units, the balance of A comprising from 0% to 95%, by weight of anionic monomer units and/or from 0% to 95%, by weight of neutral monomer units, wherein the weight fraction of A is from 5% to 95%, any balance being independently selected from one or more of anionic monomer units and/or cationic monomer units in block and/or random fashion, and wherein at least some of the cationic moieties A are selected from those derived from monomers of formula (I): wherein R 1 is H or CH 3 R 2 , R 3 , R 4 are independently selected from linear or branched C 1 –C 6 alkyl groups; R 5 , R 6 are independently H or CH 3 ; P is from 0 to 3; q is 0 or 1; z is —(CO)O—, —C(O)NH—, or —O—; and X − is an appropriate counter ion, B is siloxane-containing moiety; n is from 1 to 50; -b- indicates that A and B are connected via the termini of A and B respectively; and -g- indicates that either A or B segment is attached anywhere pendant on the B or A block respectively; -r- indicates that A and B are polymerised to form a random copolymer; and wherein at least some of the cationic moieties A are selected from those derived from monomers of formula (II): in which: each R 10 , R 11 , R 12 , R 13 and R 14 is independently selected from alkyl, hydroxylalkyl or aminoalkyl groups in which the alkyl moiety is a linear or branched C 1 –C 6 chain; R 15 is hydrogen, methyl or ethyl; q is from 0 to 10, r is from 1 to 6; Z 1 is as defined for Z in formula (I); Z 2 represents a (CH 2 ) s group, s being from 1 to 6; Z 3 is a linear or branched C 2 –C 12 , polymethylene chain optionally interrupted by one or more heteroatoms or heterogroups, and optionally substituted by one or more hydroxyl or amino groups; and each X − , is independently as defined in formula (I); and and also from ethylenically unsaturated monomers containing an aliphatic or aromatic cyclic moiety which contains a charged nitrogen (N + ) atom.
