Description

Complex detergent composition

The present invention relates to a composite detergent composition, and more specifically, to the emulsification of the surfactant, solvent, and the ternary system of water in the form of "water-in-oil", by mixing a fabric softener, an antistatic agent, an enzyme agent, and a dispersant therein. Solving the drawbacks of dry cleaning and at the same time it relates to a dry cleaning alternative complex detergent composition that can be easily washed by high-quality clothing at home washing.

Until now, protein-based fibers such as wool and silk, artificial dogs, and regenerated fibers such as acetate, which have been damaged by alkalinity, lose their shine and shrink due to chemical damage on the surface of the fiber when washed with general detergents. Washing was not possible and was only possible by dry cleaning using an organic solvent.

Conventional dry cleaning includes light oil in kerosene or heavy oil in heavy naphtha, that is, petroleum solvents equivalent to Korean Standard 5, 1,1,1-trichloroethane, 1,1,2-trichloroethane, It was made by mechanical protection using a solvent such as a hydrochlorinated hydrocarbon solvent such as trichloroethylene or perchloroethylene or a surfactant-added normal paraffin.

The dry cleaning in the laundry which has been used in the past had the inconveniences or shortcomings as listed below.

First, the contaminants of laundry can be classified into fat, protein, and water-soluble minerals, which are the dominant species. Dry cleaning removes only double-fat, and protein- and water-soluble minerals, even after repeated washing. It is not clean because it remains on the fiber.

Second, it is unsanitary because the transfer of bacteria or contaminants may occur during the washing process by being entrusted to a laundry and being washed with other laundry.

Third, because it has to be entrusted to the laundry, it takes a lot of time and is inconvenient and expensive.

As described above, it is possible to cause fiber damage and shrinkage when washing protein fibers such as wool and silk, cellulose fibers such as artificial dogs, acetate, and the like.

General detergents contain 20 to 30% by weight of surfactants and alkaline substances, so when the detergent is dissolved in an appropriate amount of water, the concentration of surfactants is 0.2 to 0.3% by weight, which is the best washing efficiency. It becomes -11. Washing with a surfactant shows proper performance in alkalinity, but in alkaline protein-based fibers are partially hydrolyzed with a carboxyl group and an amino group with a peptide bond structure, resulting in the gloss of the fiber surface and shrinkage of the fiber.

Peptide binding structures also cause hydrolysis reactions in the acid, resulting in fiber damage, which occurs in acid when rinsed with natural water during the washing process. Natural water is a kind of carbonated water that is in equilibrium with carbon dioxide in the air, and generally maintains pH5.6, which damages protein fiber.

Another phenomenon of protein-based fiber damage during washing and rinsing by general detergents is the pores that are developed in the fibers (the pores that are formed due to the elution of fat content inside the animal's fur during the processing of the hair Capillary phenomenon penetrates the washing liquid or rinsing water into the conduit to damage the fiber surface inside the pores and promote the shrinkage of the fibers.General detergents contain ionic surfactants and highly electrolytes. It easily dissolves and greatly decreases the interfacial tension of water to increase capillary phenomenon. Therefore, it rapidly penetrates into pores developed in protein-based fibers, causing fiber damage and shrinkage.

Accordingly, the present inventors have tried to prevent fiber damage and fiber shrinkage, which are disadvantages of conventional water washing, and to remove protein-based and water-soluble inorganic contaminants caused by dry cleaning. The present invention has been completed by knowing that a complex detergent composition including a fiber softener and the like can solve the problems of conventional water washing and dry cleaning.

The present invention ideally emulsifies alcoholic nonionic surfactants, special solvents normal paraffin and limonene, and the appropriate amount of water and the ternary system of water, which is the main raw material, and is a fabric softener, an antistatic agent, a protease, a lipolytic enzyme, a dispersant, The purpose of the present invention is to provide a new complex detergent composition, in which a thickener and the like are mixed for easy handling and an improved cleaning effect.

Hereinafter, the present invention will be described in detail.

The present invention is a composite detergent composition, the main component is a lauryl alcohol oxyethylene and alkanolamide 20-30% by weight, 12-30% by weight of normal carbon 10 carbon paraffins and 6-12% by weight limonene as a surfactant, It contains 0.3 to 0.7% by weight of tetraalkylammonium chloride, 0.2 to 0.7% by weight of protease, 0.3 to 0.8% by weight of lipase, 0.3 to 0.7% by weight of carboxymethylcellulose and 6 to 10% by weight of butyldiglycol. do.

Such a present invention will be described in more detail as follows.

In the present invention, the lauryl-based nonionic system having excellent detergency using oxyethylene and alkanolamide of lauryl alcohol having 12 carbon atoms is 100%, and the surfactant is 20 to 30% by weight. When diluted to 1 g / 1 liter of water to maintain the concentration of the surfactant to maintain the optimal concentration of 0.2 ~ 0.3% to prevent damage to fragile fibers, increase the cleaning effect and minimize skin damage.

The reason why this lauryl-based nonionic surfactant is good as a detergent is that it generates little bubbles, does not affect the activity of the enzyme, exhibits strong surfactant activity, and exhibits strong penetrating action even in a thin solution. In particular, in the present invention, this surfactant is very useful because it does not dissociate into ions in aqueous solution, has a great effect of removing oil pollution, has a high ability to lower surface tension, and can freely control the balance between hydrophilic and lipophilic groups.

Here, if the content of the lauryl alkoxy ethylene and the alkanolamide of the surfactant is less than 20% by weight, there is a problem in that it is difficult to obtain a surfactant effect, when exceeding 30% by weight, the cleaning power is lowered due to the excessive surfactant effect and uneconomical There is a problem.

The present invention relates to 12 to 20% by weight of chemical grade normal decane, which is a kind of 10-paraffin normal carbon, used as a dry cleaning solvent, and 6 to 12% by weight of limonene, which is a natural aromatic unsaturated naphthenic solvent extracted from an orange skin. It is used in the weight ratio of to further enhance the washing power of fat powder, and the addition of naphthenic solvent further increases the washing power of the normal paraffin solvent.

If the content of the normal paraffin solvent is less than 12% by weight, there is a problem that the washing power of fat is lowered, and if the content of more than 20% by weight, there is an uneconomical problem. If there is a problem and exceeds 12% by weight there is an uneconomical problem is undesirable.

The present invention is to form a water-in-oil emulsion (WATER-IN-OIL EMULSION) by mixing an appropriate amount of water ternary system in a special solvent mixed with lauryl alcohol-based nonionic surfactant, normal paraffin and limonene in a 2: 1 weight ratio If the normal paraffin and limonene are out of the 2: 1 weight ratio, there is a problem that the cleaning power of the fat powder and the normal paraffin solvent is lowered.

By doing so, the present invention allows the washing of wool, silk, and regenerated cellulose fibers, which were conventionally washable only by dry cleaning, to be easily washed with water at home, and water-soluble inorganic materials that were not removed by dry cleaning by performing water washing. Can be completely removed. In addition, fatty acid glyceride lipid-based contaminants secreted from the skin of the human body, which are the main constituents of fiber contaminants, realize a stronger washing effect than water washing with a conventional surfactant or dry cleaning with a solvent.

In addition, tetraalkylammonium chloride is used in the present invention as 0.3 to 0.7% by weight as a fabric softener and an antistatic agent, but if the content is less than 0.3% by weight, there is a problem that it is difficult to obtain a fiber softening and antistatic effect, and the fiber exceeds 0.7% by weight. Is too flexible and uneconomical.

In addition, although some of the proteins are water-soluble, protein contamination such as skin debris, blood, protein-based foods, molds, etc. are caught between the fibers are not dissolved or dispersed in water, other organic solutions, and the surfactant is not easily removed by the action. Many of these difficult protein contaminations can be removed using enzymes. In the present invention, protease is an enzyme that breaks down proteins into water-soluble amino acids. Action to completely remove the decomposition.

If the content of the protease is less than 0.2% by weight, there is a problem in that the decomposition of the protein is poor due to the weak action of the enzyme, and if it exceeds 0.7% by weight, there is an uneconomic problem.

In addition, in the present invention, it is noted that lipase is an enzyme that breaks down fat into glycerol and fatty acids, so that the lipid contaminants were removed by adding 0.3 to 0.8 wt% of lipase to promote the removal of fat contamination by adding to detergent.

If the content of the lipase is less than 0.3% by weight, there is a problem in that decomposition of fat does not occur well, and if it exceeds 0.8% by weight, it is not preferable because there is an uneconomic problem.

The present invention adds 0.3 to 0.7% by weight of carboxymethyl cellulose as a dispersant so that the contaminants are separated well, preventing the separated contaminants from reattaching to the fiber or the washing tank, and to prevent them from adhering to the drain hose or drain in the draining process. It also serves as a key to

In addition, in the present invention, 6 to 10% by weight of butyl diglycol is added as a middle agent to increase the viscosity of the contents and improve visual effects, but when the amount is less than 6% by weight, it is difficult to achieve the desired effect. Is too high and uneconomical.

The detergent composition of the present invention is strictly neutral at pH7.1, and also dispersed in a suspension of water-in-oil emulsion to act on washing to reduce the amplification of capillary phenomenon due to the decrease in interfacial tension to prevent fiber damage. However, since the hydrolysis of the peptide bond structure occurs during water washing, fiber damage may occur, so rinsing with natural water should be completed as soon as possible to minimize fiber damage.

However, the fiber that is preshrunk because the protein-based fiber is coated with a polymer material causes little damage to the fiber in rinsing with natural water.

While general detergents are mainly alkaline in surfactant, the detergent composition of the present invention is completely neutral at pH7.1, which prevents damage to protein-based fibers and is more disadvantageous than alkaline in terms of washing effect. The washing effect is rather increased because the activator and the solvent perform a combined cleaning action.

The excellent points of the detergent composition of the present invention as described above are listed as follows.

First, high-quality clothing can be washed with water. Washing of woolen fabrics, silk fabrics, regenerated cellulose-based fibers, etc., which were conventionally washable only by dry cleaning, can be easily washed with water in a general home.

Second, protein-based contaminants are removed. Proteolytic enzymes are added to completely remove protein-based contaminants that have not been removed by conventional dry cleaning.

Third, water soluble minerals are removed. Water washing completely removes water-soluble inorganic contaminants that were not removed by dry cleaning.

Fourth, it shows strong cleaning power for fatty contaminants. By using a combination of a lauryl alcohol-based nonionic surfactant and an emulsion of an organic solvent in combination with fatty acid glyceride-based fatty contaminants secreted from the skin of the human body, which is a predominant fiber contaminant, washing with conventional surfactants or dry cleaning with a solvent More powerful and effective removal.

Fifth, it is economic. It is convenient, hygienic and economical because it can be easily washed at home.

Hereinafter, the present invention will be described in detail with reference to Examples, but the present invention is not limited by the Examples.
