International Classification:

C11D 339
C11D 3395
D06L 302
C01B 1510

US Classification:

25218642

Abstract:

A dry bleach product is based upon diperacid, particularly diperoxydodecanedioic acid. The dry product comprises separate granular, particulate and beaded components wherein the granular component is diperacid stabilized with an exotherm control agent, diluent and a binder that includes unneutralized polymeric acid. The beaded component is fragrance admixed with a water soluble starch; the particulate components include an agglomerated extender or bulking agent, a pH control agent, and protected fluorescent whitening agents, all as separate particulate components. The water content of the granular diperacid is carefully controlled, as is the ratio of exotherm control agent to diperacid.
