Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は漂白剤組成物、更に詳しくは、酵素含有漂白
剤組成物に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a bleaching composition, and more particularly to an enzyme-containing bleaching composition.
漂白剤には次亜塩素酸ソーダを主成分とする塩素系の
ものと、過炭酸ソーダを主成分とする酸素系のものとに
大きく分けることができる。The bleaching agent can be roughly classified into a chlorine-based one having sodium hypochlorite as a main component and an oxygen-based one having sodium percarbonate as a main component.
塩素系漂白剤は、酸化還元電位が高く漂白力が強いた

白剤より酸化還元電位が低いため、色・柄物を漂白して
も脱色されることが少なく、色・柄物によっては、あざ
やかに衣類を仕上げることができる。Chlorine bleach is suitable for bleaching yellowed white clothing because of its high redox potential and strong bleaching power.
It has the drawback of acting on various dyes and causing discoloration and fading of colors and patterns. On the other hand, since the oxygen-based bleaching agent has a lower redox potential than the chlorine-based bleaching agent, it is less likely to be decolored even if the color / pattern is bleached, and depending on the color / pattern, the clothing can be finished brightly.
