  #lactic #acid #90
  
  The company's high-grade lactic acid (90% lactic acid content) is produced from corn stalks using modern fermentation technology. This product is colorless and clarified viscous liquid, no bad smell, slightly sour taste, hygroscopicity, acidic reaction of aqueous solution, can be mixed with water, ethanol or ether, and is insoluble in chloroform.
  
  Information of High Purity Lactic Acid
  
  The structural formula of lactic acid is CH3CHOHCOOH, the molecular formula C3H6O3, the relative molecular mass is 90.08, and the molecule has both hydroxyl (OH) and carboxyl (COOH) functional groups. It is the most widely existed hydroxycarboxylic acid in nature and the simplest one. Hydroxamic acid. Lactic acid is widely present in animals, plants, and microorganisms. L-lactic acid and L-lactate dehydrogenase capable of metabolizing L-lactic acid are present in tissues of humans and animals, and D-lactate dehydrogenase is absent. The human body ingests L lactic acid, which can be absorbed and decomposed, while D lactic acid can not be decomposed, and it is easy to form D lactic acid enrichment in the body.

  High Purity Lactic Acid Applications
  High-purity lactic acid is a key ingredient in many industries and applications. It is a versatile, renewable, and sustainable source of acidic compounds in food and beverage, cosmetics, and pharmaceutical applications.
  
  Food and Beverage: High-purity lactic acid is used in food and beverage products as a preservative, flavoring agent, and acidifier. It is a key ingredient in dairy products, including yogurt and cheese, and is used to maintain the pH balance of certain foods.
  
  Cosmetics: High-purity lactic acid is used as an exfoliant in many skin care products, providing a gentle alternative to other physical exfoliants like scrubs and brushes. It is also an emollient in certain cosmetics to improve skin hydration and texture.
  
  Pharmaceuticals: High-purity lactic acid is used to manufacture certain pharmaceuticals, including antifungal agents, antibiotics, and antiviral drugs. It is also used as a preservative in some medicines, as well as in the manufacture of controlled-release drug delivery systems.
