Description

Antibacterial laundry detergent and preparation method thereof

Technical Field

The invention belongs to the field of household daily necessities, and particularly relates to an antibacterial laundry detergent and a preparation method thereof.

Background

The working principle of the laundry detergent is the same as that of the traditional washing powder and soap, and the active ingredients are all surfactants. The difference lies in that: the traditional washing powder and soap adopt anionic surfactant, which is mainly sodium alkyl sulfonate and sodium stearate, and have strong alkalinity (the pH value of the washing powder is generally more than 12), so that the washing powder has great stimulation and damage to skin when in use.

The laundry detergent mostly adopts nonionic surfactants, has neutral pH value, is mild to the skin, and is degraded faster than washing powder after being discharged into the nature, so the laundry detergent becomes a new generation detergent. The common evaluation indexes of the existing laundry detergent are the bactericidal effect and the product stability, and the comprehensive performance of the laundry detergent needs to be further improved
