CAS Number: 79-33-4; 50-21-5 (general CAS number)
Description: The lactic acid, produced by fermentation, is colorless, syrupy and hygroscopic liquid with slightly acid odor. The product is GRAS.
Chemical formula: CH3CHOHCOOH
[Main Usage]
(a) For Pharmaceutical
Disinfectant: Lactic acid has a strong bactericidal function, in the field of medicine as a Disinfectant.
API: It is the raw material of some drugs (such as Ciprofloxacin Lactate, Norfloxacin Lactate). Biodegradable medical devices ingredients: Lactic acid can be deep- processed into poly- lactic acid, poly-lactic acid is biodegradable and can be used for bio-degradable fibers (made of SB -orb), bio-medical and other pharmaceutical field.
(b) For Industrial
Complexing agents: In chemical nickel- plating, lactic acid become the first complexing agents choice because of its fast plating rate and good stability.
Biodegradable material: With lactic acid as raw materials can be made of poly-lactic acid, because poly-lactic acid has a good biological degradability, in the future poly-lactic acid products will replace polyethylene products which take petroleum as raw material for sure.
