The invention concerns cationic nitriles and their use as bleach activator compounds in hard surface cleaning compositions comprising a peroxygen bleach compound. The cationic nitriles have the general formula:
wherein R1 is an alkyl group of 3-10 carbon atoms, a phenyl-substituted alkyl group with a total of 7-12 carbon atoms, or a (alkyl-substituted) phenyl group of 6-10 carbon atoms, R2 and R3 are independently methyl or ethyl groups and X⊖ is a counterion.
The hard surface cleaning compositions are preferably aqueous liquids, comprising hydrogen peroxide as the peroxygen bleach compound.
本发明涉及阳离子腈类及其作为漂白活化剂化合物在包含过氧漂白化合物的硬表面清洁组合物中的用途。阳离子腈类化合物的通式如下
其中 R1 是 3-10 个碳原子的烷基、总计 7-12 个碳原子的苯基取代的烷基或 6-10 个碳原子的(烷基取代的)苯基,R2 和 R3 独立地是甲基或乙基,X⊖ 是反离子。
硬表面清洁组合物最好是水性液体,包括过氧化氢作为过氧漂白化合物。
