L-Cysteine hydrochloride (HCl) is a hydrochloride salt of the non-essential amino acid L-Cysteine, with the chemical formula C3H8ClNO2S. It is a white or almost white crystalline powder that is highly soluble in water. L-Cysteine HCl is commonly used in the food industry as a flavor enhancer and dough conditioner, as well as in the pharmaceutical industry as an antioxidant and reducing agent. It is also used in cosmetics and personal care products, such as hair treatments and skin creams, due to its ability to break down disulfide bonds and improve the texture and appearance of hair and skin. Like L-Cysteine base, L-Cysteine HCl is a precursor to glutathione, which is an important antioxidant in the body that can help protect cells from damage caused by free radicals and oxidative stress.
