Technical Field

The invention relates to the technical field of laundry detergents, and particularly relates to an antibacterial laundry detergent for infants.

Background

The global washing articles tend to be diversified, and products which are energy-saving, water-saving, efficient, mild and convenient to use and meet the requirements of safety and environmental protection are the mainstream directions for the development of current and future washing products.

The laundry detergent replaces anhydrous sodium sulphate serving as a filling agent in the washing powder with water which is rich in resources and low in price, solves the problem of dust pollution caused by the washing powder in the using process, is simple in preparation process, has no stimulation to skin, is mild in performance, and becomes the first choice of household washing products. In order to ensure no stimulation in the use process, the use amount of some effective components with strong decontamination capability in the laundry detergent is reduced, so that the disadvantage of weak decontamination effect of the laundry detergent is caused.

With the increasing awareness of health, the cleaning of clothes cannot meet the mere cleaning effect, and the sterilization and disinfection of clothes while cleaning becomes the first choice of consumers. The skin of the baby is fragile and sensitive, the body resistance is low, and common washing powder and laundry detergent can remain on clothes and cause irritation and damage to the skin of the baby, so that when the baby laundry detergent is selected, on the premise of ensuring the cleaning function of the baby laundry detergent, the baby laundry detergent needs to be carefully selected, and products which do not irritate the skin of the baby and have a certain protection effect are selected. The laundry detergent has antibacterial and disinfecting functions on the market, but the disinfecting components commonly added in the laundry detergent are chlorine-containing disinfectants, oxygen-containing disinfectants or alcohol-containing disinfectants, and both surfactants and disinfectants adopted in the laundry detergent have unpleasant pungent odor; it is irritant and corrosive to fabric and skin; the stability is poor; the compatibility with other raw materials is poor; the environment is not friendly, and the health of the baby is easily damaged.

Most of the current commercially available infant washing products have poor washing effect for reducing irritation and toxicity of residues; or similar to the components of adult washing products, but the concentration is reduced, the washing effect cannot be improved, and the irritation to the skin of the infant cannot be reduced. With the improvement of the requirements on the quality of life, the market demand of the baby detergent is gradually increased, so that the development of the green environment-friendly baby detergent which is safer and has no stimulation and ensures good washing effect is very necessary.
