Description

Oxycarbonyl Compound for Activation of Bleaching and Bleaching Composition comprising the same}

The present invention relates to a bleaching activating compound and a bleaching composition comprising the same. More particularly, the bleaching activating compound having excellent storage stability and activating an inorganic peroxide bleaching agent even at low temperatures can exhibit excellent bleaching and washing effects and bactericidal effects. And a bleaching composition containing the same.

In Korea, in order to achieve the bleaching effect of laundry, the laundry has been put in water with detergent, boiled, dried in the sun and UV sterilized. This method is relatively excellent in the bleaching and cleaning effect, but the disadvantages of the cumbersome and dangerous process of boiling the laundry process.

Therefore, a method of using an inorganic peroxide that generates hydrogen peroxide when dissolved in water, such as sodium perborate and sodium percarbonate, has been developed. Inorganic peroxides that release hydrogen peroxide in aqueous solution include sodium perborate tetrahydrate, sodium perborate monohydrate, sodium percarbonate, sodium peroxophosphate, urea peroxohydrate, sodium peroxide, and the like. Contamination by wine, grass, etc. can be easily bleached.

However, the bleaching power of such inorganic peroxides varies greatly with temperature, for example, sodium perborate exhibits effective bleaching performance at 80 ° C. or higher and 60 ° C. or higher for sodium percarbonate. When washing in a general home, most tap water is used for washing immediately, considering that the temperature of tap water is about 20 to 25 ° C. in summer and about 5 ° C. in winter, the bleaching power of the inorganic peroxide is not sufficiently expressed. Therefore, methods have been proposed to express the bleaching power of inorganic peroxide even in low temperature water. As part of this process, bleach activating compounds have been introduced.

As a general bleach activator, tetraacetyl ethylene diamine (TAED) is the most commonly used, and US Pat. Nos. 4,412,934, 4,483,778, 4,606,838, 4,671,891, etc. Bleach is disclosed. In the case of tetraacetylethylenediamine, the bleaching power for hydrophilic juice stains is excellent, but there is a limit to the removal of oily stains such as sebum and blood from the human body. Acyl compounds have a certain effect in removing oily stains, but a large amount of acyl compounds must be used in comparison with tetraacetylethylenediamine and there is a problem that the bleaching power is still insufficient at low temperatures.

In addition, US Pat. Nos. 4,876,046, 4,259,201, 5,089,167, and the like, many organic peroxycarboxylic acids are disclosed as inorganic peroxide activating compounds. However, bleaching compositions containing organic peroxycarboxylic acids tend to be poor in storage stability, such as loss of their active oxygen due to heat instability. In order to solve this problem, coating and granulating techniques of organic peroxycarboxylic acid have been described in European Patent Nos. 396,341 and 256,443. However, the bleaching composition according to this is expensive and has low solubility in water at low temperatures. There is a disadvantage that occurs.

Recently, as a compound capable of activating the bleaching power of the inorganic peroxide bleaching agent, various efforts such as the research on the transition metal complex have been continued.

Accordingly, the technical problem to be achieved by the present invention is to solve the conventional problems as described above, excellent storage stability, and by activating the inorganic peroxide bleach at low temperatures, not only shows excellent bleaching and sterilizing effect, but also by itself To provide a bleach activating compound having excellent bactericidal power and a bleaching composition containing the same.
