1. It can be used as an acidulant with preservative effect in the food industry. It can be used in alkyd resins in the chemical industry to help improve quality. It can also be used to prepare food emulsifiers. It can be used as a varamine resist in the printing and dyeing industry to prepare printing dye pastes, etc. It can be used for leather deashing in the leather industry to shorten the tanning time and improve the quality of leather. It can also be used to produce biodegradable polymer materials such as polylactic acid. It is used as a solvent for non-water-soluble dyes such as phenazine blue and alcohol-soluble sky blue. It is used as a general acidulant, bactericide, preservative, mildewproof agent, etc. in the food industry. It is used as a mordant and solvent in the dyeing industry. It is used as a deashing agent in the leather industry.
2. It is mainly used as a conditioner and emollient for skin or hair, and an acidulant for adjusting pH value. It is used in skin creams and lotions, shampoos and conditioners, and hair care products, as well as shaving products and detergents.
3. Food acidulants and preservatives, preparation of lactates, plasticizers, and leather, wool spinning, printing and dyeing, medicine and other industries. In cosmetics, it is used to make acid creams.
4. Lactic acid plays an important role in the complexing agent of chemical nickel and other metals. It can effectively form stable complexes with metal ions, improving the efficiency and quality of the electroplating process. As a complexing agent, lactic acid has good solubility and stability, ensuring the uniformity and glossiness of the electroplated layer. During the electroplating process, it can adjust the pH value of the solution, optimize the electroplating conditions, and reduce the occurrence of defects. The use of lactic acid helps to improve the adhesion and corrosion resistance of the electroplated layer and extend the service life of the product.
5. Lactic acid was originally obtained from yogurt, so it became lactic acid. Lactic acid is widely distributed in nature, and lactic acid is produced in fermented feed and pickled sauerkraut.
6. Lactic acid bulk is used as a decalcifier in industry, mainly in fruity and dairy flavors. It is used in cheese, meat products, and dairy products.
