Abstract
Improved alkaline chlorinated concentrate compositions are provided which exhibit reduced chlorine loss over extended storage periods and which, when diluted, yield high foaming chlorinated use solutions. The concentrate compositions of the invention include from about 0.5-8% by weight alkali metal hypochlorite, from about 1.0-20% by weight of alkali metal hydroxide, and at least about 3% by weight of a surfactant system including respective amounts of a chlorine-stable trialkylamine oxide and a saturated C.sub.6 -C.sub.12 fatty acid soap, with an amine oxide:fatty acid soap weight ratio of from about 90:10 to about 25:75. The pH of the concentrates exceeds 12.5.
