US Patent:

50891677, Feb 18, 1992
Filed:

Aug 22, 1986
Appl. No.:

6/899461
Inventors:

Thomas S. Coyne - Livermore CA
Blanca L. Haendler - Livermore CA
Daniel H. Klapprott - Brentwood CA
Frances E. Mitchell - Pleasanton CA
Dale S. Steichen - Livermore CA
Suzanne M. Thompson - Rochester NY
Assignee:

The Clorox Company - Oakland CA
International Classification:

C11D 339
C11D 760
US Classification:

25218626
Abstract:

In one embodiment, the invention provides a stable peracid bleach composition comprising discrete granules which comprise peracid, namely, diperoxydodecanedioic acid. In another preferred embodiment, enzymes are present in the composition separate from the discrete peracid granules. In both the enzyme-containing and non-enzyme containing compositions, peracid and exotherm control agents are combined in a discrete granule in which the amount of water is carefully controlled to result in, respectively, maximum peracid and enzyme stability. Standard bleaching composition adjuncts such as fillers, brighteners, pH control agents and the like may be included in the compositions apart from the discrete peracid granules.

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.
