(+)-l-Methionine

L-Methionine (CAS 63-68-3) is a sulfur-containing essential amino acid supplied as a pure single enantiomer, also referenced as L-Met, H-Met-OH, and Cymethion. It carries no E-code designation and is classified under HS code 29304010. The compound is commercially sourced through fermentation or chemical synthesis routes.

In personal care formulations, L-Methionine functions as a hair and skin conditioner by donating sulfur groups that support keratin integrity and moisture retention. As an antioxidant, it scavenges reactive oxygen species and protects sensitive active ingredients from oxidative degradation. In food and feed applications, it serves as a nutritional supplement correcting methionine deficiency in plant-based protein diets.

L-Methionine is available in feed-grade, food-grade (FCC compliant), and pharmaceutical-grade (Ph.Eur. monograph) specifications. It is fully registered under REACH and supplied in standard 25 kg bags or fiber drums. Kosher and Halal certifications are obtainable depending on the production batch.
