Preparation of color-stable, light-colored, aqueous salt pastes of wash-active, α-sulfofatty acid esters |
| abstract |
This invention is directed to a process for the preparation of color-stable, light-colored aqueous salt pastes of wash-active esters of α-sulfofatty acids with monohydric C 1 -C 8 -alcohols by a combined bleaching treatment of dark-colored α-sulfofatty acid ester salt paste with hydrogen peroxide and alkali metal hypochlorite. According to the process, dark-colored α-sulfofatty acid ester salt paste is first subjected in a preliminary bleaching step to bleaching with alkali metal hypochlorite in a neutral to mildly alkaline aqueous medium, any excess metal hypochlorite is removed, and the paste is subjected in a final bleaching step to bleaching in a mildly acidic medium with hydrogen peroxide or with one or more compounds which yield hydrogen peroxide. |
