Patent

CA 1079152

Abstract of the Disclosure Excellent liquid laundry-detergent compositions are obtained by combining (1) alkanolamine, (2) nonionic surfactant, (3) sodium carboxymethylcellulose, (4) fabric brightener(s), (5) solvent, and (6) water. The preferred compositions of the invention also usually contain optional ingredients, such as dyes and perfumes. The alkanolamines promote the action of the nonionic surfactants. Moreover, it is desirable to use some triethanolamine for its stabi- lizing effect. mixture of alkanolamine and nonionic surfactants is compatible with sodium carboxymethylcellu- lose, an excellent agent for avoiding redeposition of soil. The compositions according to the invention have good detergent activity when used at temperatures such as 49 to 60 degrees Centigrade. They afford a liquid laundry deter- gent which is at least as active, pound for pound, as the powder laundry detergents now in common use.
