Abstract

A liquid cleaning composition comprising an amphoteric surfactant and a microcapsule that comprises a cationically charged coating. Also, the use of such a liquid cleaning composition for pretreating a fabric is disclosed.

First claim

What is claimed is:

1 . A liquid cleaning composition comprising:
a) from about 0.1% to about 5%, by weight of the composition, of an amphoteric surfactant; b) from about 0.11% to about 0.25%, by weight of the composition, of a microcapsule, wherein said microcapsule comprises: a shell comprising an outer surface, a core encapsulated within said shell, and a coating coating said outer surface, wherein said coating is cationically charged.

2 . The composition according to claim 1 , wherein said amphoteric surfactant is an amine oxide.

3 . The composition according to claim 1 , wherein said shell comprises a melamine formaldehyde.

4 . The composition according to claim 1 , wherein said coating comprises an efficiency polymer having the following formula:

wherein:
d) a and b each independently range from about 50 to about 100,000;
e) each R 1 is independently selected from H, CH 3 , (C═O)H, alkylene, alkylene with unsaturated C—C bonds, CH 2 —CROH, (C═O)—NH—R, (C═O)—(CH 2 ) n —OH, (C═O)—R, (CH 2 ) n -E, —(CH 2 —CH(C═O)) n —R, —(CH 2 ) n —COOH, —(CH 2 ) n —NH 2 , or —CH 2 ) n —(C═O)NH 2 , the index n ranges from 0 to 24, E is an electrophilic group, R is a saturated or unsaturated alkane, dialkylsiloxy, dialkyloxy, aryl, or alkylated aryl, further containing a moiety selected from the group consisting of cyano, OH, COOH, NH 2 , NHR, sulfonate, sulphate, —NH 2 , quaternized amine, thiol, aldehyde, alkoxy, pyrrolidone, pyridine, imidazol, imidazolinium halide, guanidine, phosphate, monosaccharide, oligo, polysaccharide, and a combination thereof;
f) R 2 or R 3 is absent or present:
(i) when R 3 is present each R 2 is independently selected from —NH 2 , —COO—, —(C═O)—, —O—, —S—, —NH—(C═O)—, —NR 1 —, dialkylsiloxy, dialkyloxy, phenylene, naphthalene, or alkyleneoxy; and each R 3 is independently selected the same group as R 1 ;
(ii) when R 3 is absent each R 2 is independently selected from —NH 2 , —COO—, —(C═O)—, —O—, —S—, —NH—(C═O)—, —NR 1 —, dialkylsiloxy, dialkyloxy, phenylene, naphthalene, or alkyleneoxy; and
(iii) when R 2 is absent, each R 3 is independently selected the same group as R 1 ; and

wherein said efficiency polymer has: an average molecular mass from about 1,000 Da to about 50,000,000 Da; a hydrolysis degree of from about 5% to about 95%; and/or a charge density from about 1 meq/g to about 23 meq/g.

5 . The composition according to claim 4 , wherein said efficiency polymer is selected from the group consisting of polyvinyl amine, polyvinyl formamide, polyallyl amine, and copolymers thereof.

6 . The composition according to claim 1 , wherein said core comprises a perfume oil.

7 . The composition according to claim 1 , further comprising a rheology modifier selected from the group consisting of hydroxy-containing crystalline material, polyacrylate, polysaccharide, polycarboxylate, alkali metal salt, alkaline earth metal salt, ammonium salt, alkanolammonium salt, C 12 -C 20 fatty alcohol, di-benzylidene polyol acetal derivative, di-amido gallant, a cationic polymer comprising a first structural unit derived from methacrylamide and a second structural unit derived from diallyl dimethyl ammonium chloride, and a combination thereof.

8 . The composition according to claim 1 , comprising:
a) from about 0.3% to about 2%, by weight of the composition, of said amphoteric surfactant, wherein said amphoteric surfactant is a C 10 -C 18 alkyl dimethyl amine oxide; b) from about 0.11% to about 0.25%, by weight of the composition, of said microcapsule, wherein said coating comprises an efficiency polymer that is a polyvinyl formamide; and c) from about 0.05% to about 1%, by weight of the composition, of a hydrogenated castor oil.

9 . The use of the liquid cleaning composition according to claim 1 , for pretreating a fabric.

10 . The use of a liquid cleaning composition for pretreating a fabric, wherein the composition comprises:
a) an amphoteric surfactant, preferably said amphoteric surfactant is an amine oxide; b) a microcapsule, wherein said microcapsule comprises: a shell comprising an outer surface, a core encapsulated within said shell, and a coating coating said outer surface, wherein said coating is cationically charged.
