L-Cysteine Hcl Monohydrate,Colorless to white crystalls or crystal powder, slightly special smell sour, melting point 175 ºC (decomposition).Soluble in water, the aqueous solution is acidic, the pH value of 1% solution is about 1.7, and the pH value of 0.1% solution is about 2.4.Also soluble in alcohol, and acetic acid, not soluble in ether,, benzene, etc.It has the function of reducing, anti-oxidation and preventing non-enzymatic Browning.
L-Cysteine Hcl Monohydrate is soluble in water and can be quickly absorbed by the human body by injection or tablet.It is the main raw material for production of carboxymethyl cysteine and acetylcysteine.

L-Cysteine is widely used in fields of medicine, food processing, biological study, materials of chemical industry and so on.
Used in the cure of liver disease, antioxidant and antidote.
Used in cosmetic.
1. L-Cysteine hydrochloride monohydrate has an effective detoxification.
2. L-Cysteine hydrochloride monohydrate can effectively prevent and treat radiation injury.
3.L-Cysteine hydrochloride monohydrate can remove the skin melanin itself, change the nature of the skin itself, the skin becomes natural whitening. It is a kind of ideal natural whitening cosmetics.
4. L-Cysteine hydrochloride monohydratecan improve the symptoms of inflammation and skin allergies.
5.L-Cysteine hydrochloride monohydrate on horny skin disease is also effective hypertrophy.
6. L-Cysteine hydrochloride monohydrate has a function to prevent biological aging,

1. N-acetyl-cysteine is the acetylated form of L-cysteine which is more efficiently absorbed and used. It is also an antioxidant that is helpful against viruses.
2. N-acetyl-cysteine has been used as a liver protectant and to break up pulmonary and bronchial mucus.
3. N-acetyl-cysteine can boost glutathione levels in cells.
Widely used in fields of medicine, food processing, biological study, materials of chemical industry and so on. It is a promotor for bread fermentation.It promotes the form of glutelin and prevents from getting ageing.
Also used in cosmetic. It is used in natural fruit juice for preventing Vitamin C oxide. It has a detoxification for poison of
aromafic acid. It is used for protecting against radiation harm and therapy of bronchitis and liquefy sputum.
4. N-Acetyl-L-Cysteine is a conditionally essential amino acid, one of only three sulfur-containing amino acids, the others being taurine (which can be produced from L-cysteine) and L-methionine from which L-cysteine can be produced in the body by a multi-step process.
5. N-Acetyl-L-Cysteine can act as an antioxidant, may prevent liver diseases, and can help to thicken the individual diameters of existing hair if taken regularly.
