Acetyl Carnitine Hcl
What is Acetyl Carnitine Hcl?
Acetyl Carnitine HCl is the hydrochloride salt of N-acetyl-L-carnitine, an amino acid derivative naturally present in the body and involved in cellular energy processes. In cosmetics, it functions as a skin conditioning agent and humectant, drawing moisture to the skin's surface to support hydration. This stable, water-soluble compound appears in serums, creams, and lotions, enhancing product texture and skin feel. Its quaternary ammonium structure aids penetration into the upper skin layers, promoting suppleness without greasiness. Sourced through acetylation of carnitine, it offers compatibility in various formulations, contributing to overall skin comfort and resilience. Official databases like CosIng classify it solely for skin conditioning, underscoring its role in everyday personal care rather than specialized treatments.
