DL-lysine hydrochloride

DL-Lysine hydrochloride (CAS 70-53-1) is the racemic salt form of lysine, supplied as a stable, water-soluble solid for use across food, pharmaceutical, and cosmetic manufacturing. Unlike the L-form used in nutritional supplementation, the DL-racemate is primarily valued as a functional ingredient in formulation and research contexts where optical purity is not a requirement.

In pharmaceutical manufacturing, it functions as a buffering and stabilizing agent in injectable formulations, lyophilized drug products, and API salt formation for various applications. Cosmetic formulators incorporate it into skin care products to regulate pH and support moisture retention in creams, serums, and hair conditioning systems for improved performance.

Food-grade applications include use as a processing aid and pH modifier in certain specialty food systems. It also serves research and analytical laboratories as a reference standard. The material is used as a reagent-grade amino acid salt for biochemical assay development. DL-Lysine hydrochloride is available as a white crystalline powder for industrial use.

It is supplied in technical, pharmaceutical, and reagent grades, with pharmaceutical material typically conforming to USP or BP specifications for quality assurance. Packaging ranges from kilogram-scale laboratory quantities to bulk industrial bags for larger manufacturing operations, ensuring flexible supply chain solutions for all clients.
