Abstract By inclusion of an alkali metal soap and an alkanolamine in a liquid detergent composition which contains a mixture of sodium tripolyphosphate and tetrapotassium pyrophosphate, a stable liquid, both at 0° C. and at 52° C. is obtained, in the presence of a hydrotrope. This system can also incorporate hydrogen peroxide, without any detrimental effect on its chemical or physical stability.
