Esters of monosaccharides and their lower alkyl glycosides are effective both as surfactants and as bleach activators (peracid precursors). The compounds are non-toxic and biodegradable. They act as nonionic surfactants and are effective in soil removal from textiles, e.g. of fatty soiling. In the presence of a hydrogen peroxide source, the sugar derivatives are perhydrolyzed during the washing process to form long-chain peracid. This enhances the bleaching effect, especially on hydrophobic stains.
单糖酯及其低级烷基糖苷既可用作表面活性剂,也可用作漂白剂活化剂(过酸前体)。这些化合物无毒,可生物降解。它们可作为非离子表面活性剂,有效清除纺织品上的污垢,如脂肪污垢。在有过氧化氢源的情况下,糖衍生物会在洗涤过程中发生过水解,形成长链过酸。这就增强了漂白效果,尤其是对疏水性污渍的漂白效果。
