The present invention relates to a detergent composition in aqueous solution comprising,
(i) a surfactant selected from anionic, nonionic, zwitterionic and cationic surfactants and mixtures thereof,
(ii) a precursor compound capable of giving rise to a peroxygen compound in the presence of water,
(iii) a bleach activator capable of enhancing the bleaching activity of the peroxygen compound so formed,
(iv) a suds suppressing agent and
(v) a detergent builder,
characterised in that the bleach activator comprises one or more cyclic anhydrides containing at least one nitrogen atom in the alpha position with respect to at least one of the carbonyl functions in the anhydride and the activator is at least partially soluble in water.
These compounds show bleaching activity at relatively low temperatures.
本发明涉及一种水溶液洗涤剂组合物,其中包括
(i) 选自阴离子、非离子、齐聚阳离子和阳离子表面活性剂及其混合物的表面活性剂、
(ii) 能在水中生成过氧化合物的前体化合物、
(iii) 能提高所形成的过氧化合物的漂白活性的漂白活化剂、
(iv) 抑泡剂和
(v) 增洁剂、
其特征在于漂白活化剂包括一个或多个环状酸酐,酸酐中至少一个羰基官能团的 α 位上含有至少一个氮原子,并且活化剂至少部分溶于水。
这些化合物在相对较低的温度下具有漂白活性。
