    摘要: The invention relates to a process for stabilizing particulate alkali metal percarbonate by coating by coating it with an aqueous solution, preferably concentrated, of a complex formed from a boric acid or borate and an organic diol, polyol or hydroxycarboxylic acid, to the resulting coated product, and to compositions including the product. The coating can additionally contain an alkali metal neutral salt such as sodium chloride or sodium sulphate.

    摘要: Improved oxygen generating agents and oxygen generating catalysts are disclosed. The oxygen generating agent comprises sodium carbonate peroxyhydrate, 2Na.sub.2 CO.sub.3.3H.sub.2 O.sub.2, as an oxygen generating source and calcium carboxymethyl cellulose (Ca-CMC) as a bonding agent. The oxygen generating catalyst comprises hydrogen peroxidase as an essential ingredient, and salt cake and polyvinyl alcohol (PVA) as accessory ingredients. The hydrogen peroxidase, the salt cake and the PVA are kneaded with each other and, thereafter, granulated or tabletted so as to form the catalyst. The oxygen generating agent of this invention provides a stable oxygen supply for a long time. This agent is also remarkably improved in its preservation. The oxygen generating catalyst permits free control of the lasting time of oxygen generating reaction. This catalyst can be preserved free from deterioration of its performance for a long time.

    摘要: 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 peroborates, 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 least 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.
