Abstract

A laundry detergent composition having: (a) detersive surfactant; (b) bluing agent, and (c) a clay and soil removal/anti-redeposition agent; and (d) optionally, one or more additional laundry detergent ingredients.

First claim

What is claimed is:

1. A laundry detergent composition comprising:
(a) detersive surfactant;
(b) bluing agent, wherein the bluing agent has the following structure:

wherein:
R 1 and R 2 are independently selected from the group consisting of: H; alkyl; alkoxy; alkyleneoxy; alkyl capped alkyleneoxy; urea; and amido;
R 3 is a substituted aryl group;
X is a substituted group comprising sulfonamide moiety and optionally an alkyl and/or aryl moiety, and wherein the substituent group comprises at least one alkyleneoxy chain that comprises at least four alkyleneoxy moieties; and

(c) a clay and soil removal/anti-redeposition agent selected from the group consisting of:
(I) random graft co-polymers comprising:
(i) hydrophilic backbone comprising polyethylene glycol; and
(ii) hydrophobic side chain(s) selected from the group consisting of: C 4 -C 25 alkyl group, polypropylene, polybutylene, vinyl ester of a saturated C 1 -C 6 mono-carboxylic acid, C 1 -C 6 alkyl ester of acrylic or methacrylic acid, and mixtures thereof;

(II) cellulosic polymers having a degree of substitution (DS) of from 0.01 to 0.99 and a degree of blockiness (DB) such that either DS+DB is of at least 1.00 or DB+2DS-DS 2 is at least 1.20;
(III) polyester soil release polymers having a structure according to one of the following structures (I), (II) or (III):
—[(OCHR 1 —CHR 2 ) a —O—OC—Ar—CO—] d   (I)

—[(OCHR 3 —CHR 4 ) b —O—OC- s Ar—CO—] e   (II)

—[(OCHR 5 —CHR 6 ) c —OR 7 ] f   (III)

wherein:
a, b and c are from 1 to 200;
d, e and f are from 1 to 50;
Ar is a 1,4-substituted phenylene;
sAr is 1,3-substituted phenylene substituted in position 5 with SO 3 Me;
Me is H, Na, Li, K, Mg/2, Ca/2, Al/3, ammonium, mono-, di-, tri-, or tetraalkylammonium wherein the alkyl groups are C 1 -C 18 alkyl or C 2 -C 10 hydroxyalkyl, or any mixture thereof;
R 1 , R 2 , R 3 , R 4 , R 5 and R 6 are independently selected from H or C 1 -C 18 n- or iso-alkyl; and
R 7 is a linear or branched C 1 -C 18 alkyl, or a linear or branched C 2 -C 30 alkenyl, or a cycloalkyl group with 5 to 9 carbon atoms, or a C 8 -C 30 aryl group, or a C 6 -C 30 arylalkyl group; and
(IV) any combination thereof; and

(d) optionally, one or more additional laundry detergent ingredients.

2. A composition according to claim 1 , wherein the bluing agent has the following structure:

wherein:
R 1 and R 2 are independently selected from the group consisting of: H; alkyl; alkoxy;
alkyleneoxy; alkyl capped alkyleneoxy; urea; and amido;
U is a hydrogen, a substituted or unsubstituted amino group;
W is a substituted group comprising an amino moiety and optionally an alkyl and/or aryl moiety, and wherein the substituent group comprises at least one alkyleneoxy chain that comprises at least four alkyleneoxy moieties;
Y is a hydrogen or a sulfonic acid moiety; and
Z is a sulfonic acid moiety or an amino group substituted with an aryl group.

3. A composition according to claim 2 , wherein R 1 is an alkoxy group and R 2 is an alkyl group.

4. A composition according to claim 1 , wherein the composition comprises C.I. fluorescent brightener 260 having the following structure:

wherein the C.I. fluorescent brightener 260 is either:
(i) predominantly in alpha-crystalline form; or
(ii) predominantly in beta-crystalline form and having a weight average primary particle size of from 3 to 30 micrometers.

5. A composition according to claim 1 , wherein the detersive surfactant comprises:
(i) alkoxylated alkyl sulphate anionic detersive surfactant having an average degree of alkoxylation of from 0.5 to 5; and/or
(ii) predominantly C 12 alkyl sulphate anionic detersive surfactant.

6. A composition according to claim 1 , wherein the composition is substantially free of zeolite builder, and wherein the composition is substantially free of phosphate builder.

7. A composition according to claim 1 , wherein the composition comprises an enzyme selected from the group consisting of:
(a) a variant of thermomyces lanuginosa lipase having >90% identity with the wild type amino acid and comprises substitution(s) at T231 and/or N233;
(b) a cleaning cellulase belonging to Glycosyl Hydrolase family 45;
(c) a variant of AA560 alpha amylase endogenous to Bacillus sp. DSM 12649 having:
(i) mutations at one or more of positions 9, 26, 149, 182, 186, 202, 257, 295, 299, 323, 339 and 345; and
(ii) one or more substitutions and/or deletions in the following positions: 118, 183, 184, 195, 320 and 458; and

(d) any combination thereof.

8. A composition according to claim 1 , wherein the composition comprises an oxaziridinium-based bleach catalyst having the formula:

wherein: R 1 is selected from the group consisting of: H, a branched alkyl group containing from 3 to 24 carbons, and a linear alkyl group containing from 1 to 24 carbons; R 2 is independently selected from the group consisting of: H, a branched alkyl group comprising from 3 to 12 carbons, and a linear alkyl group comprising from 1 to 12 carbons; and n is an integer from 0 to 1.
