[ Characteristic ] : L-Carnitine is white crystal or a white crystalline hygroscopic powder. It has a slight characteristic odor. L-Carnitine is so hygroscopic that can liquefy when it is exposure to air. L-Carnitine is highly soluble in water, alcohol, alkaline solution and dilute mineral acids. It is almost insoluble in acetone or ethyl acetate.

[ Application ] : Pharmaceutical, Health-care product, Drink of athlete, feed additive.

[ Package ] : 25Kg/fiber drum or as request.
