Abstract
Low cost, highly aqueous, thickened heavy duty liquid laundry detergent compositions are provided. Such compositions contain relatively low levels of surfactant materials, certain viscosity-enhancing agents, and very large amounts of water. Only minimal amounts of other detergent composition adjuvants are permitted in such compositions.
Claims8
A highly aqueous, heavy duty liquid laundry detergent composition which provides cost effective stain and soil removal performance when used in fabric laundering operations and which is of acceptable viscosity for use in home fabric laundering operations, said composition characterized by:
- (A) from 2% to 5% by weight of the composition of an anionic surfactant component which is free of aromatic-based anionic surfactants and which comprises alkyl polyethoxylate sulfates wherein the alkyl group contains from 8 to carbon atoms and polyethoxylate chain contains from 1 to 20 ethylene oxide moieties;
- (B) from 0.2% to 10% by weight of the composition of a nonionic surfactant component which is free of aromatic-based nonionic surfactants and which comprises:
- i) from 0.1% to 8% by weight of the composition of fatty alcohol ethoxylates of the formula R1 (OC2H4)nOH wherein R1 is a C8-C16 alkyl group and n is from 1 to 16;
- and
- ii) from 0.1% to 1.0% by weight of the composition of a surfactant amine having the formula:
- wherein R1 is a C6-C12 alkyl group n is from 2 to 4, X is a bridging group which is selected from NH, CONH, COO, or O or X can be absent;
- and R3 and R4 are individually selected from H, C1-C4 alkyl, or (CH2—CH2—O(R5)) wherein R5 is H or methyl;
- (C) from 0.1% to 3% by weight of the composition of a viscosity-enhancing agent component selected from the group consisting of alkali metal and alkaline earth metal chlorides and formates, polyacrylic compositions having a molecular weight of from 500,000 to 1,000,000 and mixtures thereof;
- and
- (D) from 86% to 94% by weight of the composition of an aqueous, non-surface active liquid carrier which comprises no more than 3% by weight of the composition of liquids other than water.
A highly aqueous, heavy duty liquid laundry detergent composition which provides cost effective stain and soil removal performance when used in fabric laundering operations and which is of acceptable viscosity for use in home fabric laundering operations, said composition characterized by:
- (A) from 3.8% to 4.2% by weight of the composition of an anionic surfactant component which is free of aromatic-based anionic surfactants and which comprises sodium C12-C16 alkyl ether sulfates containing from 1 to 6 moles of ethylene oxide;
- (B) from 0.5% to 3% by weight of the composition of a nonionic surfactant component which is free of aromatic-based nonionic surfactants and which comprises
- i) from 0.1% to 1% by weight of the composition of C10-C14 fatty alcohol ethoxylates containing from 3 to 10 moles of ethylene oxide;
- and
- ii) from 0.2% to 0.6% by weight of the composition of a surfactant amine selected from C8-C16 amidopropyl dimethyl amines;
- (C) from 0.1% to 2% by weight of the composition of a carboxylate detergency builder selected from C10-C22 fatty acids and salts and citric acid and its salts;
- (D) from 0.05% to 0.5% by weight of the composition of an enzyme component which comprises one or more protease detergent enzymes and one or more amylase detergent enzymes but contains no more than 0.01% by weight of said composition detergent enzymes other than protease and amylase detergent enzymes;
- (E) from 0.1% to 2% by weight of the compositions of a sodium chloride, sodium formate or calcium formate viscosity-enhancing agent;
- and
- (F) from 88% to less than 90% by weight of the composition of an aqueous, non-surface active liquid carrier which comprises no more than 2% by weight of the composition of liquids other than water.
