ABSTRACT:
Laundry detergents and automatic dishwashing compositions with activated bleaching systems which are effective under mixed soil conditions, especially mixtures of hydrophobic and hydrophilic soils and stains are presented. The preferred bleach activators are N-acyl caprolactams and nonanoyloxybenzene sulfonate. A particularly preferred embodiment comprises a 1:2.2:7.7 molar ratio of N-acyl caprolactam to alanoyloxybenzenesulfonate to peroxygen bleaching compound. This mixed caprolactam, alkanoyloxybenzenesulfonate bleaching composition delivers stronger than expected performance on both hydrophobic and hydrophilic stains and on dingy clean up.
