ABSTRACT:
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 stabilizing effect. The mixture of alkanolamine and nonionic surfactants is compatible with sodium carboxymethylcellulose, 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 detergent which is at least as active, pound for pound, as powder laundry detergents now in common use.
