Title:
BLEACHING ACTIVATING CATALYST AND BLEACHING AGENT COMPOSITION CONTAINING THE SAME COMPOUND
Document Type and Number:
Japanese Patent JP2000282091
Kind Code:
A
Abstract:

To obtain the subject catalyst capable of improving the bleaching performance at low temperatures of a peroxy compound used for bleaching, cleaning, etc., of foulings such as stains sticking to clothes or tea incrustations sticking to tableware made of ceramics, etc., by composing the catalyst of a specific ligand and a transition metal.

This catalyst is obtained by including (A) a ligand represented by formula I and/or formula II [R1 to R3 are each H, a halogen, OH, an alkoxy(carbonyl), COOH or a 1-5C alkyl; R4 is a 1-10C alkyl or a substituted alkyl; n is 3 or 4; l and m are each 1-3] and having three coordinating nitrogen atoms and (B) a transition metal. Mn, Fe, Cu, Co, etc., are cited as the component B. The ratio of the components A to B is preferably (1:4) to (200:1) expressed in terms of molar ratio. The catalyst is preferably added into a bleaching bath so as to provide 0.01-1,000 ppm component B expressed in terms of the metal. The bleaching agent composition is obtained by including the catalyst and a peroxy compound.
