Lactic acid is an organic acid that is commonly used in the food, pharmaceutical, and cosmetic industries. It is produced through the fermentation of carbohydrates, primarily in milk, and can also be produced synthetically. The global production of lactic acid is estimated to be around 330,000 metric tons per year, with China being one of the major producers.

Lactic acid is commonly used as a food additive for its sour taste and preservative properties. It is also used in the production of biodegradable plastics, as well as in the textile and leather industries for its ability to soften and improve the feel of fabrics.

China is a major producer of lactic acid, thanks to its abundant supply of raw materials and advanced production technology. The country also benefits from its large domestic market, which allows for efficient distribution and cost-effective production. Additionally, Chinese manufacturers have been investing in research and development to improve the quality and functionality of their lactic acid products, further enhancing their competitiveness in the global market.
