Description
- 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.
- As such an oxygenic bleaching agent, sodium percarbonate and sodium perborate are particularly utilized from the standpoint of bleaching performance and stability.
- However, 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.
- Although tetraacetyl ethylene diamine (TAED), acetoxybenzene sulfonic acid salts, tetraacetyl glycoluril and glucose pentaacetate have been representatively used as the bleach activator, they are still insufficient in bleach activating effects.
- The present inventors previously found that a compound which reacts with hydrogen peroxide to form an organic peracid having a cationic group is excellent as a bleach activator (see U. S. Patent Nos. 4,933,103 and 5,059,344, and European Patent Publication-A Nos. 371809 and 403152).

- The present inventors have extensively studied to solve the above-mentioned problems and have found that a composition which comprises hydrogen peroxide or a peroxide which liberates hydrogen peroxide in an aqueous solution thereof and compounds represented respectively by the following general formulae (I) and (II) at a specified ratio solves the aforementioned problems:
in which R¹ is, either a straight- or branched-chain, substituted or unsubstituted, alkyl having 1 to 20 carbon atoms or alkenyl having 2 to 20 carbon atoms, R² and R³ are, each independently, an alkyl having 1 to 3 carbon atoms and A and B are, each independently, either a straight- or branched-chain, substituted or unsubstituted, alkylene having 2 to 20 carbon atoms, and
in which R¹, R², R³ and A are defined above. - The present invention has been accomplished on the basis of this finding.
- Namely, the present invention provides a bleach or bleaching detergent composition which comprises or essentially consists of:
- (a) hydrogen peroxide or a peroxide which liberates hydrogen peroxide in an aqueous solution thereof,
- (b) a quaternary ammonium compound having the general formula (I);
- (c) an amide derivative having the general formula (II);
- R¹ in the formulae (I) and (II) is, preferably, either a straight- or branched-chain, alkyl having 1 to 20 carbon atoms and having at least one substituent selected from the group consisting of a hydroxyl group and a halogen atom or alkenyl having 2 to 20 carbon atoms and having at least one substituent selected from the group consisting of a hydroxyl group and a halogen atom.
- When R¹ in the formulae (I) and (II) is alkyl, it is preferably, either a straight- or branched-chain, alkyl having 1 to 9 carbon atoms.
- When R¹ in the formulae (I) and (II) is alkenyl, it is preferably a straight-chain alkenyl having 2 to 17 carbon atoms.
- A and B in the formulae (I) and (II) are preferably, each independently, a straight-chain alkylene having 2 to 10 carbon atoms.
- The molar ratio of component (a)/component (b) is in the range of preferably from 99.9/0.1 to 20/80, and more preferably from 99/1 to 50/50.
- The weight ratio of component (b)/component (c) is in the range of preferably from 100/0.1 to 100/4.
- The composition may further comprise at least one component selected from the group consisting of a bleach activator other than component (b), a surfactant, a divalent metal ion-sequestering agent, an alkaline agent, an inorganic electrolyte, an antiredeposition agent, an enzyme, a fluorescent dye, a stabilizer for the peroxide, a perfume and a coloring matter in their respective effective amounts.
