Abstract
An aqueous bleaching composition having a pH from about 11 to 14, comprising an alkali metal hypochlorite, an alkali metal orthophosphate buffer, and an alkali metal pyrophosphate builder. The buffer increases the stability of the hypochlorite formulation to be comparable to a non-built composition of equal hypochlorite content despite the solution's increased ionic strength. The builder significantly aids in soil removal during laundering operations.
