Abstract
Abstract A nonaqueous liquid nonbuilt laundry detergent bleach booster composition comprising a suspension or solution of diacetyl methyl amine (DAMA) organic liquid peroxy compound precursor in liquid nonionic surfactant. The bleach booster composition comprises a nonaqueous liquid nonionic surfactant containing a stable suspension or solution of diacetyl methyl amine (DAMA) and an anti-gel and viscosity control agent. The bleach booster composition is easily pourable and readily disperses on contact with water.
