A bleaching composition characterised in that it comprises:
(a) a peracid precursor corresponding to the following general formula:
wherein R represents C1-C20 alkyl, alkoxyl, or cycloalkyl; R1 represents a group which contains at least one carbon atom which is singly bonded directly to N; n represents an integer of from 1 to 6; and X represents methylene or a heteroatom; or
wherein n is as defined above; R2 represents a group which contains a carbon atom doubly bonded directly to N, and, either X represents a heteroatom, R represents C4-C17 alkyl, or both;
(b) a bleach-effective amount of a source of hydrogen peroxide;
and, optionally,
(c) an adjunct selected from surfactants, builders, fillers, enzymes, fluorescent whitening agents, pigments, dyes, fragrances, stabilizers and buffers is disclosed. Peracid precursors containing such oxynitrogen leaving groups provide new, proficient and cost-effective compounds for fabric bleaching.
一种漂白组合物,其特征在于它包括
(a) 符合以下通式的过酸前体:
其中 R 代表 C1-C20 烷基、烷氧基或环烷基;R1 代表含有至少一个直接与 N 单键结合的碳原子的基团;n 代表 1 至 6 的整数;X 代表亚甲基或杂原子;或
其中 n 如上定义;R2 代表一个含有一个碳原子的基团,该碳原子直接与 N 双键结合,且 X 代表一个杂原子,R 代表 C4-C17 烷基,或两者兼有;
(b) 漂白有效量的过氧化氢源;
以及
(c) 选自表面活性剂、增白剂、填料、酶、荧光增白剂、颜料、染料、香料、稳定剂和缓冲剂的辅助剂。含有这种炔氮离去基团的过酸前体为织物漂白提供了新的、熟练的和具有成本效益的化合物。
