Abstract
Solid detergent compositions containing alpha-amine oxide surfactants and alkaline materials, which exhibit a pH of greater than 9.0 at a concentration of 1% by weight in water, are disclosed. The alpha-amine oxides have improved stability against metal-catalyzed decomposition in the present compositions. The compositions preferably also contain other surfactants and detergent adjunct materials.
Claims27
A solid detergent composition comprising:
- (a) from about 1% to about 80% by weight of an amine oxide surfactant of the formula ##STR2## wherein R.sup.1 is hydrogen or a C.sub.1 -C.sub.20 hydrocarbyl group;
- each R.sup.2 is a C.sub.1 -C.sub.20 hydrocarbyl group or a C.sub.2 -C.sub.3 alkylene oxide group containing from 1 to about 10 alkylene oxide units;
- and X is hydrogen or a water-soluble metal, ammonium or substituted ammonium cation;
- provided that the total number of carbon atoms in hydrocarbyl groups at the R.sup.1 and R.sup.2 substituents is from about 8 to about 36;
- and
- (b) from about 2% to about 99% by weight of an alkaline material which exhibits a pH of greater than 9.0 at a concentration of 1% by weight in water.
