Abstract
A liquid heavy duty laundry detergent composition comprising a suspension of builder salt in liquid nonionic surfactant in which the stability of the composition is improved by the addition of small amounts of an aluminum salt of higher fatty acid, especially aluminum tristearate. The yield stress of the compositions can be improved with the same or lower plastic viscosity, especially at low concentrations of the aluminum salt. The aluminum salts also exhibit an antifoaming effect and can be used to boost softening.
Claims18
A fabric treating composition which comprises a non-aqueous liquid, fabric-treating inorganic particles suspended in said non-aqueous liquid and an aluminum salt or a straight or branched, saturated or unsaturated aliphatic carboxylic acid having from about 8 to about 22 carbon atoms to increase the stability of the suspension, said non-aqueous liquid comprising a nonionic surfactant.
A non-aqueous heavy duty, built laundry detergent composition which is pourable at high and low temperatures and does not gel when mixed with cold water, said composition comprising
- at least one liquid nonionic surfactant in an amount of from about 20 to about 70% by weight;
- at least one detergent builder suspended in the nonionic surfactant in an amount of from about 10 to about 60% by weight;
- a compound of the formula RO(CH.sub.2 CH.sub.2 O).sub.n H
- where R is a C.sub.2 to C.sub.8 alkyl group and n is a number having an average value in the range of from about 1 to 6,
- as a gel-inhibiting additive in an amount up to about 5% by weight;
- an acid organic phosphoric acid compound, as an anti-settling additive, in an amount up to about 5% by weight;
- an acid-terminated nonionic surfactant as a gel-inhibiting additive, in an amount up to about 1 part per part of said liquid nonionic surfactant;
- aluminum salt of a C.sub.8 to C.sub.22 aliphatic carboxylic acid in an amount of from about 0.1 to about 3% by weight;
- and
- optionally, one or more detergent adjuvants selected from the following:
- enzymes, corrosion inhibitors, anti-foam agents, suds suppressors, soil suspending or anti-redeposition agents, anti-yellowing agents, colorants, perfumes, optical brighteners, bluing agents, pH modifiers, pH buffers, bleaching agents, bleach stabilizers, bleach activators, enzyme inhibitors and sequestering agents.
In a method for filling a container with a non-aqueous liquid laundry detergent composition in which the detergent is composed at least predominantly of a liquid nonionic surface active agent and for dispensing the composition from the container into a water bath in which the laundry is to be washed, wherein the dispensing is effected by directing a stream of unheated tap water onto the composition in the container whereby the composition is carried by the stream of water, into the water bath, the improvement comprising including in the non-aqueous composition from about 0.1 to about 3% by weight of an aluminum salt of a C.sub.8 to C.sub.22 aliphatic carboxylic acid.
