Problems solved by technology

The disadvantages of using organic solvents in clothing pre-washing agents are as follows: organic solvents are easy to volatilize at room temperature, and most of them have varying degrees of poisonous effects on the human body after inhaling the vapor through the respiratory tract
Secondly, most organic solvents have varying degrees of irritation to the skin and mucous membranes. Contacting with the skin will dissolve the skin oil and penetrate into the tissue, causing epidermal keratinization, stimulating the epidermis and causing redness and swelling.
Organic solvents have problems of flammability, explosiveness and environmental pollution, and have obvious limitations

Abstract

The invention relates to a total-effect clothing pre-washing agent free from an organic solvent. The organic solvent has different degrees of toxic actions to the human body, is combustible and easy to explode, pollutes the environment and has obvious limitation. The total-effect clothing pre-washing agent disclosed by the invention is prepared from an anionic surfactant, a nonionic surfactant, an emulsifier with an HLB value of 5-13, aids, a short chain surfactant, a pH value regulator, a hydrotropic agent, a preservative, essence and water, wherein the emulsifier with the HLB value of 5-13 replaces a common organic solvent and is scientifically compatible with detergents and other aids, oily dirt is removed in emulsifying and dispersing modes, the ratio of the emulsifier to the detergent is between 1:10 and 2:1, an effect of removing multiple stains is achieved, and the stain removal ratios of standard carbon black stained cloth, protein stained cloth and sebum stained cloth are all over 1.0.

Description

technical field [0001] The invention relates to a laundry pre-washing agent, in particular to an organic solvent-free full-effect laundry pre-washing agent. Background technique [0002] Clothes pre-washing agent, also known as clothing pre-stain remover, collar clean, and collar clean, is a special detergent for clothing parts, which is specially used for washing the neckline, cuffs and heavy dirt of clothing parts. Stains on clothes, especially oily stains and stubborn stains, are difficult to clean with ordinary detergents. It is necessary to pre-wash the stains in some parts before washing the whole clothes to strengthen the overall cleaning effect of the clothes. [0003] At present, there are many patents on the laundry pre-washing agent comprising organic solvent components. For example, patent CN201310434546.3E discloses an enzyme-containing sterilizing collar cleaner, which contains organic solvents 1,2-propylene glycol and tetrachloroethylene; 3%-5% butyl ether a...
