Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent composition for clothing used to remove stubborn stains, especially due to sweat, body fluids, food juices and the like. 2. Description of the Related Art Dirt such as sweat, body fluids, food juices, etc., which adhere to clothing and have been left for a long time, are difficult to remove by ordinary washing and dry cleaning. For this reason, detergents containing bleach or enzymes are used to wash such stains.However, it takes a long time after the stains adhere to such detergents, and they completely dry and become insoluble. There is a problem that it is difficult to remove the dirt that has become. If you use a strong detergent and wash it over time, you can remove such stubborn dirt, but the clothing fabric may be damaged,
In the case of a patterned material, there is a problem that it is not practical because it may be discolored. [0003] The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to remove stubborn dirt such as body fluids and food juice from clothing. The object is to make it easy to drop the item without damaging it. [0004] The object of the present invention is to provide, by volume, 0.3% to 1.5% lactic acid, 0.5% to 2.5% citric acid, 0.1% A garment detergent composition comprising 4% to 2% glacial acetic acid, 0.8% to 4% glycerin and the balance water is shaded in a stubborn soiled area for a predetermined period of time. Is achieved by softening dirt and making it easy to peel off from clothing. DETAILED DESCRIPTION OF THE INVENTION A detergent composition for clothing according to the present invention contains 0.3% to 1.5% lactic acid by volume and 0.1% lactic acid.
5% to 2.5% citric acid and 0.4% to 2%
Glacial acetic acid, 0.8% to 4% glycerin and the balance water. If the thickness is smaller than this, the detergency deteriorates, and if the thickness is thicker, the viscosity becomes too high, causing problems. When using the detergent composition for clothing, it is sealed in a sprayer or the like, and sprayed on a stubborn soiled area of clothing, such as a neck, a cuff, a side, and the like, and is shaded. [0006] Before the detergent composition for clothing is completely dried, for example, if it is allowed to dry for 7 to 8 minutes, lactic acid or citric acid or the like acts on the adhered dirt, so that the dirt becomes soft and soft. In this state, depending on the type of clothing, normal washing with water,
Alternatively, dirt softened by dry cleaning is removed together with water-soluble or oil-soluble dirt that has adhered to other portions and is easily removed. Now, the present invention will be described in further detail with reference to Examples. Example 1 A detergent composition for clothing was prepared by dissolving 6 cc of lactic acid, 9 cc of citric acid, 7 cc of glacial acetic acid, and 14 cc of glycerin in 1600 cc of distilled water. It was sprayed on the cuff of a lightly stained shirt and shaded for 10 minutes, followed by dry cleaning. As a result, the dirt on the cuffs could be cleaned cleanly. Example 2 A detergent composition for clothing was prepared by dissolving 14 cc of lactic acid, 21 cc of citric acid, 18 cc of glacial acetic acid, and 26 cc of glycerin in 850 cc of distilled water. After spraying on the neck of a heavily soiled shirt and shading for 10 minutes, dry cleaning was performed. As a result, it was possible to clean the dirt on the cuffs. Example 3 6 cc lactic acid, 12 cc citric acid, 8 cc glacial acetic acid,
A detergent composition for clothing was prepared by dissolving 14 cc of glycerin in 560 cc of distilled water, sprayed on a stain of fruit juice on a T-shirt several days after being stained, and dried for 10 minutes. Regular washing was done. As a result, the stain fell cleanly. [0010] In addition to the above two types of detergent compositions for clothing, those having an intermediate concentration between them are prepared, and those having an intermediate concentration are usually used. For the appropriate part, the one having the above-mentioned concentration may be selectively used in accordance with the degree of contamination. In the present invention, as shown in the examples, several types of detergent compositions for clothing may be prepared, and one having an appropriate concentration may be used depending on the situation of dirt. Further, in the case of stains mainly composed of body fluids such as blood and sweat, the mixing ratio of lactic acid is increased, and in the case of stains mainly composed of fruit juice, the mixing ratio of citric acid is increased. For example, a composition in which the mixing ratio of each component is changed within the scope of the present invention according to the type of soil may be used. Also,
If yellowing pigments such as sweat remain in clothing even after washing with this clothing detergent composition, it is recommended to perform a rust removal treatment using a 0.1% hydrogen fluoride solution. Is done. Since the detergent composition for clothing according to the present invention is constituted as described above, according to the present invention, stubborn stains such as body fluids and food juices may damage clothing. And can be easily dropped.
