Claims1
A stable liquid detergent comprising:
- (a) about 11.5% of an ethoxylated alcohol nonionic surfactant of the formula R(C.sub.2 H.sub.4 O).sub.n OH wherein R is an aliphatic hydrocarbyl radical containing from about 12 to about 13 carbon atoms, wherein the average n is about 6.5, said surfactant having an HLB value of from about 10 to about 13;
- (b) about 6.7% of an amine oxide surfactant having the formula ##STR8## wherein R.sub.1 is an alkyl radical containing from about 12 to about 16 carbon atoms and R.sub.2 and R.sub.3 are methyl;
- (c) (i) about 5% of a water-soluble salt of citric acid;
- (ii) about 7% of a water-soluble salt of pyrophosphoric acid, and
- (d) about 12% of a hydrophilic material selected selected from the group consisting of monoalkyl esters of phosphoric acid, ethoxylated monoalkyl esters of phosphoric acid and mixtures thereof, said hydrophilic material having an HLB value above about 14;
- and
- (e) about 46% water.
