Abstract
Cellulose-based soil release ethers are used in detergent compositions containing C.sub.10 -C.sub.13 alkyl sulfate surfactants, and substantially free from interfering amounts of longer-chain length alkyl sulfates, to provide optimal soil release performance.
Claims26
A detergent composition comprising:
- a. from about 5% to about 50% by weight of a surfactant component consisting essentially of a water-soluble alkyl sulfate wherein the alkyl substituent has a chain length in the range of C.sub.10 -C.sub.13, or mixtures thereof, said surfactant component containing less than about 5% by weight of C.sub.15 and higher alkyl sulfates;
- b. from about 1% to about 5% by weight of a water-soluble alkyl sulfate wherein the alkyl substituent is C.sub.14 ;
- c. from about 0.1% to about 3% by weight of a soil release ether component selected from the group consisting of alkyl cellulose ethers, hydroxyalkyl cellulose ethers and hydroxyalkyl alkyl cellulose ethers;
- d. from about 0% to about 70% by weight of a detergency builder component;
- and
- e. the balance of the composition comprising detergency adjunct materials and carriers selected from the group consisting of perfumes, optical bleaches, fillers, anti-caking agents, fabric softeners, perborate bleaches, enzymes, water, water-alcohol mixtures and mixtures thereof.
