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. Such as lactic acid in meat processing and lactic acid for baking. 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, like lactic acid in black soap, 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 lactic acid medicine, as well as in the manufacture of controlled-release drug delivery systems.

Pet industry: Lactic acid in dog food is a natural preservative that can effectively inhibit the growth of bacteria in pet food and extend the shelf life of the product. Due to its natural and safe properties, lactic acid is widely used in pet food to reduce the number of harmful microorganisms in food and protect the health of pets.
