l-Lysine acetate

L-Lysine Acetate (CAS 57282-49-2) is the acetate salt form of the essential amino acid L-Lysine, also referenced as L-LYS AC, L-LYSINE AC, and H-LYS-OH ACOH. It carries no assigned E-code and is classified under HS code 29224110 within the amino acids and peptides category.

In personal care formulations, L-Lysine Acetate functions as a hair and skin conditioner by binding to negatively charged keratin surfaces, improving texture and moisture retention. It also serves as a pH buffer in cosmetic and pharmaceutical systems, where its acetate counterion provides controlled buffering capacity across mildly acidic ranges.

L-Lysine Acetate is available in food-grade (FCC) and pharmaceutical-grade (Ph.Eur.) specifications to meet requirements across nutrition, cosmetics, and healthcare applications. It is subject to REACH registration for supply within the European Economic Area. Standard packaging formats vary by grade and supplier volume requirements.
