Description

Dishwashing Liquid Detergent Composition {LIQUID DETERGENT COMPOSITION USING KITCHEN}

[TECHNICAL FIELD OF THE INVENTION]

The present invention relates to a liquid detergent composition, and more particularly, to improve cleaning power, which is a basic function of detergents, to deodorize odors generated in kitchens, to remove odors from fishy smells generated from kitchen utensils, and to microorganisms harmful to humans. It relates to a dishwashing liquid detergent composition with significantly improved sterilization function.

[Private Technology]

In general, various types of bacteria and yeast are present on cutting boards and dish cloths used in the kitchen, resulting in odors. Frequently washing dishes, food residues on dishes, etc. can cause skin irritation such as eczema. Cause.

In addition, it is difficult to remove fishy smell (amine smell), kimchi, garlic, onion smell (mercaptan stain) generated from food wastes or meats such as fish, and it is caused by the smell of food left after meals and dregs hanging on drains. Odor is generated by odorous substances containing ammonia, amines, mercaptans, and the like from bacteria and the like.

In order to solve the above problems, a method of separately using a conventional disinfectant disinfectant and a boiling method have been attempted as a method for removing bacteria or microorganisms, and a method of circulating indoor air as a method of removing odors. , A method using a dedicated deodorant has been attempted. However, the above method has to use a dish detergent, disinfectant, deodorant, etc. alternately, there was a hassle to boil dishcloths and cutting boards.

In addition, Japanese Patent Application Laid-open Nos. Hei 4-298513 and Hei 2-217064 disclose a general deodorant composition using green tea extract and polyol, and Japanese Patent Laid-Open No. Hei 2-297239 contain limonene and benzalkonium chloride. A deodorant and a fungicide are disclosed, and Japanese Patent Laid-Open No. 1-186267 discloses a sterilizer and a deodorant using a chlorine compound and an alcohol. U.S. Patent No. 5,260,053 and Japanese Patent Application Laid-open No. Hei 2-103473 disclose a deodorant using a combination of plant essence oils. However, the prior art as described above has a problem that the bactericidal and deodorant effects are insignificant, and are not stable to the human body or the environment.

In addition, there were many dish detergents having a sterilizing effect, but a variety of strains that cause odor or harmful to the human body, while having a sterilizing effect only on a specific bacteria using only a single substance, the disinfecting and deodorizing effect felt by the user is insignificant. There was a problem. In addition, conventionally, the synthetic sterilization component was mainly used to maximize the effect of sterilization and deodorization, which had a problem of lack of stability for the human body or the environment. In the case of extracts can only be used in small amounts, there is a problem in itself lacking antibacterial and deodorant function. In addition, even in the case of an organic acid known as a function of deodorization and sterilization, there is a problem that it is difficult to exhibit the deodorizing and bactericidal effect on various bacteria when including a single organic acid.

Therefore, there is an urgent need to develop a kitchen liquid detergent that is stable to the human body, has less skin irritation, has excellent cleaning power, and has a markedly improved sterilization function against microorganisms harmful to the human body by removing odor from fish dishes.

In order to solve the conventional problems as described above, an object of the present invention is to provide a kitchen liquid composition that is excellent in cleaning power, and the sterilization function for the microorganisms harmful to the human body and the odor removing effect to the fishy smell generated from the tableware.
