摘要:
A sterilizing composition for a food-packing material which comprises the following components (1) and (2) : (1) an aqueous solution containing peracetic acid, hydrogen peroxide and acetic acid, and (2) a peracetic acid sterilizing power-improving agent comprising one or two or more compounds selected from the group consisting of esters obtained from a C2-C8 aliphatic acid and a C2-C8 aliphatic alcohol, C2-C8 aliphatic alcohols and aliphatic alcohols having a benzene ring.
摘要:
A stabilizing agent for peroxide-bleaching procedure includes (A) a component including a homopolymer or copolymer of alpha -hydroxyacrylic acid or water soluble salt or polylactone of the homo- or co-polymer, (B) a component including a homopolymer or copolymer of acrylic acid, methacrylic acid and/or maleic acid and water-soluble salt of the homo- or co-polymer, (C) a component including DTPA, TTHA or water-soluble salt thereof and optionally (D) a component including a water-soluble inorganic Mg salt and is used to pretreat a fiber material with a pretreating liquid containing the stabilizing agent before bleaching with peroxide, or to bleach the fiber material by a bleaching liquid containing a peroxide bleaching agent and the stabilizing agent.

摘要:
An oxidizing composition comprises an aqueous solution of peracetic acid, hydrogen peroxide and acetic acid and a fragrant component uniformly solubilized in the peracetic acid-containing aqueous solution by aid of a surfactant component, the fragrant component comprising at least one fragrance material which is chemically stable in the presence of peroxide compounds and effectively masks the irritating odor of peracetic acid and acetic acid.
