Description

Antifoam photoactive bleach composition and detergent composition containing same

1 and 2 are spray cooling apparatus and floor bed apparatus for producing antifoam photoactive bleach,

3 is a spray and coating machine for external coding by adding a binder and an inorganic component.

The present invention relates to an antifoam photoactive bleach composition and a laundry powder detergent composition containing the same. In more detail, the present invention is a tetrabenzo-tetrazaporpine derivatives photoactivated bleaching agent as a bleaching effect active ingredient of a powder detergent, a dimethyl siloxane antifoaming agent as a defoaming effect active ingredient, a melting point of 55 Waxes, such as beeswax, candelillan, wooden wax, carbauna lead or mixtures thereof or nonionic surfactants such as polyoxyethylene glycol (molecular weight 1,000-20,000), polyoxyethylene alkyl ethers, After mixing to polyoxyethylene alkylphenyl ether, span 60 (sodium monostearate) or mixtures thereof, the composition is powdered to a particle size of 1 mm or less, and then a photoactivated bleach adheres to the fibers during washing to In order to prevent the occurrence of dyeing, water, nonionic surfactants such as polyoxyethylene alkyl ether, polyoxyethylene alkylfe Ether, polyoxyethylene glycol, polyoxyethylene propylene block copolymer, span 80 (sodium monooleate), etc. as a binder, silica, talc, bentonite, zeolite, cray Antifoaming optical activity and bleach composition of the clothing powder detergent by coating the outside of the powdered particles using a high-speed mixer using an inorganic component of 5 to 40 parts by weight and then separating the final particle size of 1 to 2mm and It relates to a powder detergent containing 0.1 to 50 parts by weight.

Conventionally, the powder detergent is a hard alkaline laundry detergent used to wash cellulose fibers such as hemp and cotton, and chemical fibers such as nylon and polyester, and hard fibers used to wash protein fibers such as wool and silk. It can be classified as a detergent (Light duty Laundry Detergent), and a weak alkaline heavy detergent is mainly used as a laundry detergent.

On the other hand, anionic surfactants such as linear alkylbenzene sulfonates, fatty acid sodium, alpha olefin sulfonates, lauryl sulfate ester salts, lauryl ethoxy sulfates, and polyoxyethylene alkyl ethers, which are the main components used as laundry detergents , Nonionic surfactants such as polyoxyethylene alkylphenyl ether and fatty acid alkanolamide are mainly used, and as an auxiliary component, a water softener such as sodium tripoly phosphate, zeolite, nitrilo triacetate, ethylene Diaminetetraacetates, acrylic polymers and antiredeposition agents and fluorescent brighteners such as distyrylbiphenyl, aminostyrene, cumin based, pyrazoline based, naphthalimide based, benzoxazole based and enzymes such as , Proteases, amylases, lipases, cellulases and bleaches such as sodium percarbonate, perborate Oxygen-based bleaches such as sodium perborate (monohydrate, tetrahydrate), magnesium peroxyphthalate, calcium peroxy monosulfate, diperoxy dodecandioic acid, and the optically active bleach tetrabenzo-tetraaza phosphine system. .

However, the powdered powder mixed with the above components have a disadvantage in that a large amount of bubbles are generated when washing with a surfactant, so that when used in a washing machine, the foam overflows or when rinsing, the number of rinses is increased and a large amount of water is used. In the case of oxygen-based bleach contained for the purpose of inhibiting enzymatic action by further fixing the protein contamination which is a solidification of the contamination attached to clothing or breaking the amino group of the protease which is a protein degradation enzyme that degrades protein contamination have. In addition, in the case of the photo-activated bleach, the powder detergent containing it is attached without being dispersed and dissolved sufficiently in an aqueous solution, there is a disadvantage that the blue spots occur partially.

The present inventors have made diligent researches to improve the above disadvantages, namely, an increase in the number of rinses due to excessive bubbles during washing, an increase in water usage, and breakdown of amino groups of proteases. It has been found that the above problems can be solved by using a suitable dispersant and coating, etc., and have completed the present invention. That is, by coating the silica particles, talc, zeolite, etc. by using a binder (binder) on the size adjusted particles it is possible to improve the solubility and dyeing problems of clothing.

Hereinafter, the present invention will be described in detail.

The present invention is 5 to 69.9 parts by weight of the silicone antifoaming component, 0.01 to 10 parts by weight of the photo-activated bleaching agent, 84.9 to 20 parts by weight of waxes and / or nonionic surfactants having a melting point of 55 to 80 ℃ and 10 to 0.1 parts by weight of the dispersant The mixture is heated to 60-85 ° C., dissolved, and then passed through a spray cooling device where it can be refluxed into a cooling gas or the compound can be sprayed through a nozzle at the top of the device, or the mixture is allowed to dry at room temperature in a floor bed device, followed by a high speed mixer. After crushing, the particle size is 1mm or less, and then 1 to 10 parts by weight of the binder and 5 to 40 parts by weight of inorganic components such as silica, talc, and zeolite are added, and the antifoam photoactive bleach for powder detergent and the same are prepared. It aims at providing the powder detergent to contain.

As the photoactivated bleach used in the present invention, a tetra benzo-tetra azapopin system is preferable, and as a defoaming component, a dimethylsiloxane system is preferable. Suitable binders in the present invention include nonionic surfactants such as polyoxyethylene glycol (molecular weight, 1,000 to 20,000), polyoxyethylene, alkyl ether, polyoxyethylene alkylphenyl ether, span 60, span 80, polyoxyethylene, propylene Block copolymer or mixtures thereof], and waxes include beeswax, candelillan, wooden wax, carbauna lead or mixtures thereof.

Suitable dispersants in the present invention are sodium acetate, xylene sulfonates, naphthalene sulfonates, condensates of formaldehyde or mixtures thereof, and inorganic components are silica, talc, zeolites or mixtures thereof.

Hereinafter, the present invention will be described in detail with reference to Examples.

-80)] was used to measure the color difference before and after washing, calculated by the following equation, and the results are shown in Table 3.

A: whiteness of raw cloth

B: Whiteness of contaminated cloth before washing

C: whiteness of contaminated cloth after washing

[Test Example 2]

(Cleaning effect test)

Empa 116 (EMPA 116, carbon black / blood / Milk) contaminated cloth 10cm × 10cm each of Swiss Empasa was added to a solution of 1.5g of detergent composition in Table 2 in 1 liter of water, and then heated at 20 ° C and 100rpm with a togotometer washer. After washing for 10 minutes and rinsing for 5 minutes, it was naturally dried to measure the color difference before and after washing using a color difference meter and calculated according to the following equation, and the results are shown in Table 3.

A: whiteness of raw cloth

B: Whiteness of contaminated cloth before washing

C: whiteness of contaminated cloth after washing

[Test Example 3]

(Deposition test)

1.5 g of the detergent composition shown in Table 2 was directly poured into the 10 cm diameter of the 30 cm × 30 cm white cotton cloth core, and the white cotton cloth of 30 cm × 30 cm was superimposed thereon, and then immersed in 1 l of water for 2 hours to dye blue on the fiber. Visually check if this occurs.

[Test Example 4]

(Defoaming effect test)

Using a solution of 2.5 g of the detergent composition shown in Table 2 in 1 L of water, the foaming force was measured by a Ross-Mile foam test at 40 ° C., and the results are shown in Table 3 below.

[Table 2] Detergent composition

TABLE 3

As shown in the test results, the bleaching effect is increased with increasing content of the photoactive bleach, and composition Nos. 3 and 4 in Table 3 are similar to the effects of sodium percarbonate (composition Nos. 6 and 7). In addition, the cleaning effect of the sodium percarbonate affects the protein enzyme so that the composition No. 6, 7, the cleaning effect is poor, but the photoactive bleach does not affect.

It does not show any effect even on dyeing of clothing, and it can be seen that the degree of foaming is gradually decreased with increasing content of the antifoaming photobleaching agent, thereby improving the rinsability.
