Document Type and Number:
Japanese Patent JP2846436
Kind Code:
B2
Abstract:
The invention relates to a bleaching composition containing an oxidant bleach and enzyme granules, in which enzyme stability is prolonged without undue loss of solubility despite intimate contact of said enzyme granules and said oxidant bleach, comprising: an oxidant bleach, selected from the group consisting of alkali-metal perborates, alkali metal percarbonates, hydrogen peroxide adducts, and mixtures thereof and hydrolase enzyme granules comprising a hydrolase enzyme core and a water soluble alkali metal silicate coating substantially encapsulating said core, said coating including at one protective agent, said agent being selected from the group consisting of transition metals; reducing agents; and mixtures thereof. Sodium percarbonate is a preferred oxidant, while transition metals combined with a sodium silicate coating provide enhanced storage stability to the enzymes thereby coated.
