Description
MarkNature’s Lauric Arginate Ethyl Ester Hydrochloride (LAE·HCl, E243) is a naturally derived, food-grade preservative and broad-spectrum antimicrobial agent approved for use in the EU as E243. Produced from L-arginine (an essential amino acid) and lauric acid (a natural fatty acid), this compound provides powerful protection against bacteria, yeasts, and molds. LAE·HCl helps extend product shelf life and maintain sensory quality without affecting flavor or texture.
This white, hygroscopic solid melts at 42–45°C and demonstrates very low solubility in water (<2%) but high solubility in ethanol (>40% w/w). In oil–water systems, it preferentially distributes into the water phase, where microbial growth is most likely to occur. Stable under normal food processing conditions and compatible with diverse formulations, LAE·HCl (E243) offers a clean-label, biodegradable, and effective alternative to synthetic preservatives.
