過酸化水素漂白におけるPHAS (ポリ-α-ヒドロキシアクリル酸ソーダ) の特性

抄録

Hydrogen Peroxide will be remarked more and more as a clean bleaching agent because of global environmental issues. Although Hydrogen Peroxide is a stable substance thermally, it decomposes with traces of heavy metals. Therefore some stabilizer is required when bleaching, and Sodium Silicate has been used conventionally. It has, however, a problem in which hard scales are produced, and a non silicate stabilizer is desired. PHAS (Sodium poly-α-hydroxyacrylate) has unique characteristics. Introduced herewith are stabilizing characteristics of PHAS in alkaline Hydrogen Peroxide comparing with other general chelating agents. PHAS has excellent stabilizing abilities especially in higher pH region. Hydrogen Peroxide concentration and temperature condition.
