Applications

FOOD:
Beverage: Lactic acid series products are widely used in beverage industry, which can be used to adjust acidity, improve flavor and strengthen nutrition of beverage products.
Candy: The use of lactic acid series products in candy can improve product flavor, inhibit sugar conversion, strengthen nutrition and prolong product shelf life.
Pickles: The addition of lactic acid and calcium lactate to pickles can make the taste of pickles more crisp, shorten the fermentation time, unify the product flavor, prolong the shelf life of pickles and maintain better color.
INDUSTRIAL: 
Lactic acid is widely used in leather industry because it has excellent permeability, mild effect, can reduce the risk of leather damage, excellent penetration effect and excellent dealkylation effect. And it is used to treat fibers in the textile industry, which can make the fibers easy to color, increase luster and make the touch soft.
Cosmetic: Lactic acid is part of the skin's inherent natural moisturizing factor, it is widely used as a moisturizer for many skin care products. lactic acid is the most effective type of AHA and has little irritation;
Lactic acid is naturally present in the hair, the effect is to make the surface of the hair shiny and bright, so lactic acid is often used as a pH regulator for various hair care products;
Lactic acid can be used as a moisturizer in various toiletries, such as body lotion, strip soap and moisturizer. It can be used as a pH regulator in liquid soaps, soaps and shampoos. In addition, the addition of lactic acid in the bar soap reduces the loss of moisture during storage and thus prevents the soap from cracking.
Medicine: Lactic acid steam disinfection in wards, operating rooms, laboratories and other places can effectively kill bacteria in the air, reduce diseases and improve health; 
In medicine, it is widely used as preservative, carrier agent, cosolvent, pharmaceutical preparation, pH regulator, etc;
Polylactic acid can be obtained by polymerization of lactic acid. Polylactic acid can be spun into silk into thread. This thread is a good surgical suture. After the suture is healed, the suture does not need to be removed. It can automatically degrade into lactic acid and be absorbed by the human body without adverse consequences. Especially in vivo surgical suture, avoiding the trouble of secondary surgical suture removal. This polymer compound can be used as an adhesive in organ transplantation and bone grafting;
Lactic acid can be directly prepared into drugs or daily health products for use;
The restriction of muscle vitality and anti fatigue.
