Abstract

The invention relates to a bactericidal fabric softener and a preparation method thereof, belonging to the technical field of daily chemicals. The softener includes the following components in parts by weight: 15-20 parts of tetramethylene-bis(lauroyloxyethyl dimethyl ammonium bromide), 15-20 parts of bis-tallow ethyl carboxyl hydroxyethyl methyl 8~10 parts of ammonium methyl sulfate, 2~4 parts of lavender, 5~10 parts of ginkgo biloba, 0.1~0.5 parts of thickener, 0.2~2 parts of color fixing agent, 80~100 parts of deionized water. Because the present invention adopts Gemini cationic surfactant and ester-based quaternary ammonium salt surfactant with good biodegradability as active substances, the product of the present invention not only has excellent softness and antistatic properties, but also is extremely friendly to the environment. Simultaneously, the product of the invention has color fixing effect and excellent bactericidal effect. In addition, the preparation method of the invention is simple and easy to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of daily chemicals, and in particular relates to a bactericidal fabric softener and a preparation method thereof. Background technique [0002] During the washing process of clothes, fine fibers tend to be entangled, tangled together, or even broken. After repeated washing of clothes, the alkaline effect of detergent will affect the inherent smoothness, extensibility and elasticity of fibers, showing The only thing is that the whole piece of clothing looks old and shapeless, and it feels stiff to the touch. This feeling becomes more obvious the more times the clothes are washed. [0003] Most of the fabric softeners currently on the market use dioctadecyldimethylammonium chloride as the main active ingredient. The biggest disadvantage of this type of softener is poor biodegradability and serious yellowing. With the improvement of public awareness, such products cannot meet the needs of social development. ...
