Description

Bleach activator comprising a mixture of alkyloxy and diamine compound and bleach composition comprising the same

The present invention relates to a bleaching activator and a bleaching composition containing the same having excellent storage stability, and activating the inorganic peroxide bleaching agent even at low temperatures, thereby exhibiting excellent bleaching and washing effects.

Bleaching pollution is generally divided into fat-soluble bleaching and water-soluble bleaching. The main source of bleaching contamination is tannic acid, which is contained in kimchi soup, red pepper powder, vegetable leaves, leaves, mustard, black tea, and wine. Tannin acid is the main source of water-soluble bleaching pollution. Contamination by pollutants containing not only tannic acid but also some kinds of alcohols such as grass water, tea and mustard forms fat-soluble bleaching pollution.

In Korea, in order to remove such various bleaching pollution, and to get the bleaching effect of the laundry, the laundry was 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 these inorganic peroxides varies greatly with temperature. For example, sodium perborate exhibits effective bleaching performance at 80 ° C or higher and at 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 20-25 ° C. in summer and about 5 ° C. in winter, the bleaching power of the inorganic peroxide is not sufficiently exhibited. Therefore, a method for expressing the bleaching power of the inorganic peroxide in low temperature water has been proposed, and as a part of this method, a bleach activating compound has been introduced.

Tetra acetyl ethylene diamine (TAED) is most commonly used as a general bleach activating compound, and acyl compounds are used as bleach activators in US Pat. Nos. 4,412,934, 4,483,778, 4,606,838, 4,671,891, and the like. The bleach used was disclosed. Tetraacetylethylenediamine has excellent bleaching power against hydrophilic bleaching contamination, but it has limitation in removing fat-soluble bleaching pollution such as sebum, mustard and grass water from human body. In addition, the acyl compound, which is another type of bleach activating compound, has a predetermined effect in removing fat-soluble stains, but has a problem that a large amount must be used in comparison with tetraacetylethylenediamine, and the effect of expressing bleaching power is still low at low temperatures. In addition, after reacting with an inorganic peroxide and an aqueous solution to express the bleaching power, there is a disadvantage that it is difficult to use a heavy odor, such as washing water, clothing.

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 losing their active oxygen due to heat instability. In order to solve this problem, coating and granulating techniques of organic peroxycarboxylic acid are described in European Patent Nos. 396,341 and 256,443. However, the bleaching composition according to this is expensive and poorly soluble in water at low temperatures. There is a disadvantage that the phenomenon occurs in the.

Recently, various efforts have been made, such as research on transition metal complexes as compounds capable of activating the bleaching power of inorganic peroxide bleach.

Therefore, the technical problem to be achieved by the present invention is to solve the above problems, firstly, it can activate the inorganic peroxide bleach even at low temperatures, not only shows excellent bleaching effect and washing effect, but also excellent sterilization power by itself, second, After reacting with inorganic peroxides in the wash water, the bleaching activator does not leave a smell in the wash water and clothes after expressing the bleaching power. Third, a bleach activator having excellent storage stability even in a high temperature and high humidity environment and a bleaching composition containing the same To provide.

Hereinafter, the bleach activator of the present invention and a bleaching composition containing the same will be described in more detail.

The organic compound represented by Chemical Formula 1 included in the bleaching activator of the present invention is not only decomposed by heat, but reacts with hydrogen peroxide only when contacted with water to release peroxycarboxylic acid, which is stable during storage, and R ₁ Due to its excellent selectivity against fat-soluble contamination, it is very excellent in bleaching power, washing power and sterilizing power for fat-soluble bleaching contamination. However, the organic compounds do not perform as much as the fat-soluble bleaching pollution with respect to the water-soluble bleaching contamination. Therefore, the present inventors are known to be very vulnerable to fat-soluble bleaching, but are excellent in water-soluble bleaching, so that the most widely used tetraacetylethylenediamine can be mixed in an appropriate ratio to treat both fat-soluble and water-soluble bleaching. In addition, when the mixture is used in a specific ratio, the bleaching power against fat-soluble bleaching is sharply increased and more preferable, and when mixed and formulated, the synergy effect of the stability is very excellent.

More specifically, the tannin component of the plant, which is the main cause of bleaching contamination, is generally removable as a water-soluble bleaching component, but when such tannin is combined with a protein, it becomes difficult to remove it as a fat-soluble bleaching contamination. At this time, the alkyloxy compound of the present invention primarily removes fat-soluble contamination, and then removes water-soluble contamination in which tetraacetylethylenediamine remains secondarily. In particular, such a bleaching process is excellent in a specific ratio, and the specific ratio is preferably a mixture ratio of alkyloxy compound to tetraacetylethylenediamine of 1 to 0.2 to 1 to 2, when 1 to 0.5 to 1 to 1 Is more preferable because it shows the best decontamination ability.

It is preferable that it is%. When the content of the mixture of the bleaching activating compounds is less than 0.01% by weight may not be sufficient to activate the inorganic peroxide, when the content exceeds 15% by weight there is a fear that the activation rate of the inorganic peroxide is too fast.

More preferably, the present invention provides a bleach activator which improves storage stability by granulating and / or coating the mixture of the bleach activating compound. If the properties of the synthesized bleach activating compound are powders, the bleach activating compound should be formulated or granulated first, which is the ratio of contact with inorganic peroxides containing active oxygen in the bleach or mixture of bleach to which the bleach activating compound is added. This is to ensure the stability by lowering the surface area. In this case, the size of the formulated particles used is suitably 1700 to 150 ㎛ in size in view of solubility.

Based on. In addition, tetraacetylethylenediamine is because the stability is superior to the alkyloxy compound, and does not have to go through a particle coating process, such as a fluidized bed in particular.

Specifically, the bleach activator granules containing a mixture of the alkyloxy bleach activating compound and tetraacetylethylenediamine of the present invention can be prepared by micronizing the mixture of the bleach activating compound and then mixing with the binder. The binder for the formulation of the bleach activating compound is preferably 0.5 to 10% by weight, based on 100% of the total formulated bleach activator. When the total amount of the binder is less than 0.5% by weight, the effect of the binder is not sufficient, and when the amount of the binder is 10% by weight or more, the content of the bleach activating compound may be relatively low, so that the expression of the bleaching power, the washing power, and the bactericidal power may not be sufficiently expressed.

The binder used should be water soluble in consideration of being used in laundry. Specific examples include polyethyleneglycol, alkyl polyethoxylate, sorbitan fatty acid esters, linear alkyl benzene sulfonate, and carboxy methyl cellulose. ), Hydroxyethyl cellulose (hydroxyethyl cellulose), methyl cellulose (methyl cellulose), hydroxypropyl cellulose (hydroxypropyl cellulose), starch, white sugar, glucose and gelatin are preferably any one or more selected from the group consisting of.
