Ethyl lauroyl arginate hydrochloride

Ethyl lauroyl arginate hydrochloride (CAS 60372-77-2), commercially known as LAE or Cytoguard LA and approved as E243 in the EU, is a cationic antimicrobial derived from natural amino acid and fatty acid precursors.

It functions as a broad-spectrum preservative and surface-active biocide across food, personal care, and pharmaceutical applications. In food manufacturing, E243 is approved for use in processed meats and certain bakery products.

This ingredient inhibits bacterial and yeast growth, extending shelf life without synthetic preservative blends. Personal care formulators incorporate LAE into rinse-off and leave-on products including shampoos and conditioners.

In these applications, it delivers both antimicrobial preservation and conditioning activity on hair and skin surfaces. In pharmaceutical topical formulations, it functions as a preservative system component where low-toxicity actives are preferred.

Home care and surface disinfection products use LAE for its rapid bactericidal action against Gram-positive and Gram-negative organisms. It remains effective at low use concentrations across various industrial formulations.

Ethyl lauroyl arginate hydrochloride is supplied as a white to off-white powder or as aqueous solution concentrates. Food-grade material is available meeting E243 regulatory specifications for global distribution.

Cosmetic-grade supply aligns with INCI-compliant quality standards for international beauty brands. Technical and pharmaceutical grades are also available depending on specific end-use requirements and purity needs.
