ABSTRACT:
Granular detergent additives contain finely divided powders of both acyloxybenzene sulfonate (AOBS), e.g. nonanoyloxybenzene sulfonate, bleach activator and an oxygen containing bleach, e.g. sodium perborate, encapsulated in a water soluble organic binder, especially a nonionic ethoxylated alcohol surfactant. The bleach and bleach activator do not react with each other until the granules are added to water at which time the reaction is substantially instantaneous and complete due to the close proximity of the reactants to each other. The granular detergent additives can be used alone or as a component of a full detergent composition to provide storage stable, low temperature effective bleaching activity.
