Abstract
Abstract A laundry additive product comprising a solid laundry additive composition containing discrete agglomerated particles of storage sensitive detergency additive water-releasably glued to a unitary, water-insoluble carrier. Preferred storage-sensitive additive are organic peracid bleaches and detergency enzymes. The compositions have improved storage-stability, dust control, reproducibility and convenience of use.

Dependent Claim
31 words
A laundry additive product characterized by: (a) a solid laundry additive composition comprising discrete agglomerated particles of storage-sensitive detergency additive water-releasably glued to the surface of (b) a unitary water-insoluble carrier.
Claim 3
Dependent Claim
35 words
A product according to Claim 1 characterized in that the storage-sensitive detergency additive is selected from detergency enzymes, bleaches, bleach activators, bleach catalysts, photoactivators, dyes, fluorescers, suds suppressors, perfumes, fabric conditioning agents, and hydrolysable surfactants.
Claim 4
Dependent Claim
32 words
A product according to Claim 1 or 2 incorporating therein an antagonist for the storage-sensitive detergency additive, and wherein the detergency additive/antagonist combination are selected from at least one of the following:
Claim 7
Dependent Claim
31 words
A product according to any of Claims 1 to 3 characterized in that the storage-sensitive detergency additive is an enzyme selected from the group consisting of proteases, amylases and mixtures thereof.
Claim 8
Dependent Claim
52 words
A composition according to any of Claims 1 to 3 characterized in that the storage sensitive detergency additive is an organic peroxy bleach selected from mono and diperoxyphthalic acid, mono and diperoxyisophthalic acid, peroxylauric acid, peroxyoctanoic acid, peroxynonanoic acid, peroxydecanoic acid, mono and diperoxydodecanedioic acid, mono and diperoxyazelaic acid and salts thereof.
