Definitions

• the present invention relates to a bleach or bleaching detergent composition containing a bleach activator having a cationic group.
• a chlorinated bleaching agent has disadvantages in that the fibers to which it is applicable are limited, i.e., it is not applicable to colored or patterned soft goods, materials, cloths, fabrics and the like, and that it has a peculiar odor, so that an oxygenic bleaching agent free from these disadvantages has recently been used widely.
• sodium percarbonate and sodium perborate are particularly utilized from the standpoint of bleaching performance and stability.
• the bleaching power of the oxygenic bleaching agent is poorer than that of a chlorinated bleaching agent, so that various bleach activators have been used together therewith.
• TAED tetraacetyl ethylene diamine
• acetoxybenzene sulfonic acid salts tetraacetyl glycoluril and glucose pentaacetate
• glucose pentaacetate tetraacetyl glycoluril
• glucose pentaacetate glucose pentaacetate
