L-Carnitine Hydrochloride
What is L-Carnitine Hydrochloride?
L-Carnitine Hydrochloride is the chloride salt of L-carnitine, a naturally occurring compound derived from the amino acids lysine and methionine, essential for fatty acid transport in cells. In cosmetics, it appears in moisturizers, serums, and cleansers, functioning primarily as a humectant by attracting and retaining water molecules in the upper skin layers to support hydration. As a skin conditioning agent, it interacts with skin lipids and proteins to enhance suppleness, smoothness, and flexibility without adding oiliness. This water-soluble ingredient integrates well into aqueous formulations, aiding in maintaining the skin's natural moisture balance and comfort during daily use across various product types.
