| 摘要 |
Bleaching compositions comprising a bleaching compound and an N-acyl-3- or 4-piperidone each preferably present in a range of about 1 to about 75 % by weight. Additives, such as surfactants, anti-foaming agents, fabric softeners, stabilizers, inorganic builder salts, buffers, enzymes and the like may also be present. The compositions can be formulated as dry concentrated mixtures encapsulated or in loose powder form, aqueous solutions, aqueous solutions containing non-aqueous solvents and like forms. The compositions are effective as bleaching agents from below room temperature to higher temperatures, biodegradable and environmentally safe.
