Description

Detergent composition for clothing

The present invention relates to a detergent composition for clothing, and more particularly, water washing is prohibited by constituting a dinimonene, which is a natural vegetable solvent, and an emulsifier as main components, and mixing propylene glycol and a known detergent additive at a specific ratio, if necessary. It is not only excellent in water washing effect on hair, silk fabric, or hemp that has been used, but also can be washed by immersion method unlike the conventional one, and it has excellent shrinkage effect in the form of fabric even after water washing, and is excellent in washing and freezing resistance. It relates to a detergent composition for.

Conventional apparel detergents mainly consist of mineral emulsifiers such as LAS (straight chain alkylsulfonate), ABS (alkylbenzenesulfonate), AOS (alphaolefinsulfonate) and vegetable emulsifiers which are fatty alcohols. Solid laundry soaps, composed of synthetic detergents and fatty acid soda, were the main dominants.

These detergents were able to effectively wash dust, urban smoke, oils such as synthetic oil or skin secretions, protein components such as keratin, and starch components such as food waste. Synthetic fibers such as nylon and acrylic fabrics, or blended fibers thereof also showed a great washing effect.

However, with the improvement of living standards, the trend of medical life is to prefer clothing made of natural fibers, and accordingly, whether or not to wash clothes for wool, dogs, horses or blends thereof has become a big issue.

Conventional laundry detergents are mainly composed of mineral synthetic emulsifiers, and during washing, additional mechanical energy such as rotation, sound waves, and impact by vibrators in the washing tank is needed. This problem remains a fatal flaw.

For this reason, in the past, such garments were subjected to dry cleaning through a laundry, and this method also had difficulties in solving environmental and economic aspects due to the use of dry cleaning agents. Conventional dry cleaning washing method is a dry washing method using petroleum-based solvents and mineral emulsifiers for high-quality clothing such as wool, silk dogs, and horseshoe.Pechloroethylene is typically used as a petroleum-based solvent. have.

Recently, the dry cleaning method is causing environmental problems because of the most commonly used physicochemical properties of perchlorethylene, which is incompatible with water and carcinogenicity. It is known to have (Sigma Aldrich library) is a serious problem when considering the toxicity of the solvent remaining in the clothes after washing or the toxicity by inhalation of volatiles during washing. In addition, since there is no waste disposal method of the finished treatment, there is a problem that it is always exposed as soil, rivers, and air pollutants.

Therefore, the inventors of the present invention have no harm to the human body and have no possibility of causing environmental pollution at the same time to solve the above problems of the conventional detergent and dry cleaning agent, and at the same time solve the problem of shrinkage or deformation of clothing caused by water washing. The innovative detergent composition for clothes of the present invention has been developed.

First of all, the present invention changed the conventional detergent and the washing style of the emulsifier type by using dilimonene, which is a natural solvent. Accordingly, the desired washing effect can be obtained even by the dipping method applied during dry cleaning washing. It is possible to wash without shrinkage.

Dilimonene used as a solvent in the present invention is an extract of natural citrus peel and is a by-product obtained by distillation from orange fruit peels of Brazil, Australia, USA and Europe. Dilimonene has ten carbon atoms as thifenoid based on its chemical structure, and because of its benzene-like structure, it possesses relatively higher decontamination ability than the conventional petroleum solvent perchlorethylene in its degreasing rate. Doing.

In addition, depending on the content of octanal, nonanal, pecanal, linanol, etc., it is used for industrial, edible, fragrance, and also for the use of some components of the deodorant composition, as in Korean Patent Publication No. 90-6845. It was written.

In addition, dilimonene is not only chemically stable because it has a high boiling point above 155 ° C as a liquid, but according to data published by the FDA, it has problems in application as a detergent as GRAS (generally recognized as safe). It is not said.

Examples of practically using such dilimonene include US Pat. Nos. 4,511,488 and 4,620,937, and British Patent No. 1,603,047. In these patents, dilimonene is used in an industrial detergent composition. The technique of using dilimonene in industrial detergent compositions is applied to cleaners used to clean the areas contaminated by industrial oils, etc., but it is applied to clothing or high-quality textiles that are sensitive to deformation such as shrinkage or discoloration by water washing. There is no example applied to the detergent composition for clothing.

In particular, the composition of the detergent composition for clothes, unlike dry cleaning agent, when used for water washing, the composition of the detergent without deformation is not known until now, and even in the method of use, mechanical energy must be applied, such as using a rotating force or air bubbles. Washing was possible.

In general, the desorption mechanism from the solid contaminant substrate can be explained by the electrostatic energy action, and the adsorption state between the contaminant particles and the substrate is separated by a differential distance while inducing an emulsifier hydration state. From this point, the contaminants are separated from the substrate to an infinite distance. The energy required is provided by the movement of the washing machine, the dispersion of water, and the ultrasonic waves. When washing using a washing machine, heavy energy is provided to the clothes by the kinetic energy of the rotor in the tank, and thus the shrinkage and deformation of the clothes are inevitable.

Therefore, if the detergent composition has a shrinkage effect while desorbing the contaminants and preventing re-adsorption by dissolving the contaminants by the immersion method of the natural solvent rather than the desorption of the contaminants by the mechanical kinetic energy of the rotor in the washing machine, the dry cleaning effect of the laundry Can be obtained at home.

Therefore, the present inventors have made efforts to overcome the above-mentioned defects of the conventional products as a main component of the dimerene and natural emulsifiers and emulsifiers, if necessary, a high-fat fatty acid, polyhydric higher alcohols and amines in a specific ratio mixed composition The present invention has been found to be surprising that it can improve the washability as well as maintain and preserve the shape stability after washing of the wool and silk fabrics, and also prevent the freezing during storage of the detergent by adding propylene glycol. The detergent composition for clothing was developed.

Thus, an object of the present invention is to provide a detergent composition for garments containing dilimonene as a main component and capable of maintaining morphological stability after washing as well as washability of the hair and silk fabrics.

Hereinafter, the present invention will be described in detail.

The present invention is characterized in that the detergent composition for clothes contains dilimonene and an emulsifier as main components.

The present invention is also characterized in that 10-35% by weight of dirimonene and 15-35% by weight of an emulsifier are contained in the detergent composition.

In addition, the present invention is characterized in that in addition to the dilimonene and the emulsifier, 0.5 to 1.5% by weight of a higher fatty acid oil, 3.0 to 5.0% by weight of polyhydric alcohols, and 1.0 to 2.5% by weight of amines are contained in the total composition.

Referring to the present invention in more detail as follows.

The present invention relates to a detergent composition for a gel-like garment which is excellent in washability and can preserve the form stability after washing of fabrics by using dirimonene, which is a natural orange peel liquid, as a main component, and adding high-fat fatty acid oil thereto. In the case of using dilimonene, the amount thereof is used in an amount of 10 to 35% by weight based on the total detergent composition, and used together with 15 to 35% by weight of an emulsifier. In addition, 0.5 to 1.5% by weight of fatty acid, 3.0 to 5.0% by weight of polyhydric alcohol and When 1.0 to 2.5% by weight of the organic amine compound is used together, a more effective cleaning effect can be obtained.

In the present invention, if dilimonene is less than 10% by weight, it is difficult to exert sufficient washing effect by the dipping method, and when it exceeds 35% by weight, it is easy to cause deformation and discoloration in laundry washing.

In the present invention, as an emulsifier, 15.0 to 35.0% by weight of two or more mixtures selected from oxyethylene oxypropylene alkyl ether, oxyethylene oxypropyl alkyl benzene ether, oxyethylene lauryl ether and oxyethylene alkyl benzene ether are used. They can take part in each other's functions, but they are not perfect and can only be expected to have a big synergy when mixed. If the amount of the emulsifier is less than 15.0% by weight or more than 35% by weight, the balance of emulsification stability is broken and there is difficulty in long-term preservation.

In the present invention, as the higher fatty acid, 0.5 to 1.5% by weight of one or two or more mixtures selected from oleic acid, stearic acid, and palmitic acid are used. If the amount is less than 0.5% by weight, the alkalinity of the product is increased, and the protein fibers such as hair and dogs are increased. It will have a detrimental effect, and if it exceeds 1.5% by weight, it will not be able to have the viscosity of the desired product, which will reduce its value. The most suitable viscosity is 80,000-150,000 cp at spindle number 2, 2.5 rpm, 20 ° C. of the Brookfield Viscometer.

In addition, in the present invention, a polyethylene glycol as a polyhydric alcohol is used as the fabric softener, which shows various characteristics according to the molecular weight, of which the most effective molecular weight is in the range of 300 to 600, and 3.0 to 5.0 weight based on the total weight. It is suitable to contain%, but if the average molecular weight of polyethylene glycol is less than 300, there is a problem in the emulsion stability of the finished product, there is a defect that the layers are separated. And if the amount is less than 3.0% by weight does not have a softening effect, when the amount exceeds 5.0% by weight there is a defect that remains as a residue after washing.

In addition, as the organic amine compound used in the present invention, 1.0 to 2.5% by weight of one or two or more mixtures selected from monoethanolamine, diethanolamine and triethanolamine are used. If the content is not more than 2.5% by weight, the alkalinity is high, which causes excessive stress on the wool and silk fabric, which causes deformation.

In addition, the present invention is composed of 10 to 35% by weight of dirimomen, 0.5 to 1.5% by weight of higher fatty acids, 15 to 35% by weight of emulsifiers, 1.0 to 2.5% by weight of amines, and 3.0 to 5.0% by weight of polyhydric alcohols. It can be applied by adding an additional ~ 10.0% by weight, which is very effective to prevent freezing during the winter storage of the detergent, and has stability even up to -20 ℃. If the propylene glycol is out of 10% by weight, the stability of the emulsion zone is lost, if less than 1% by weight it is difficult to exert a floating function.

In addition, the content of dilimonene in the composition of the present invention can be said to be a reasonable concentration to maximize the washing effect is present in the total water washing tank from 0.01% to 0.2% by weight.

On the other hand, in the present invention, in addition to the oily portion, such as dilimonene, higher fatty acids, emulsifiers, polyhydric alcohols and the like, the remaining portion is composed of water, triethanolamine and propylene glycol as an aqueous portion.

The gel-like detergent composition of the present invention as described above is composed of dirimonene as a main component and excellent washing properties by forming a high-fat fatty acid, an emulsifier, a polyhydric alcohol, an organic amine compound and the like in a specific range as described above, after washing the wool fabric It can maintain and preserve morphological stability by preventing deformation and shrinkage, and can improve the dye desorption and electrostatic generation of laundry, as well as freeze prevention effect, and can be usefully used as a laundry detergent for various fabrics.

Hereinafter, the present invention will be described in detail by way of examples, but the present invention is not limited by the examples.
