Ethyl lauroyl arginate HCl (LAE), derived from natural lauric acid and L-arginine, is shown here to provide broad-spectrum activity against microorganisms including Malassezia furfur and Propionibacterium acnes. In vitro tests corroborated by in vivo evaluations suggest its efficacy in anti-dandruff and dermo-purifying applications.
The Required D-Value: Evaluating Product Preservation in Relation to Packaging and Consumer Use/Abuse

Cosmetic and pharmaceutical products are subject to microbial contamination and spoilage during use. In 1970, Halleck published the recommendations of the Preservation Subcommittee of the Toiletry Goods Association Microbiology Committee, which stated that preservation studies should consider product formulation, manufacturing conditions, packaging, product stability and continued effectiveness of the preservative system during the intended use by consumers.

Benzoic acid (BA) is a leading choice due to its long and successful history of use preserving foods, drugs and cosmetics. Affirmed as GRAS (Generally Recognized As Safe) by the US Food & Drug Administration (FDA), BA and its sodium salt, sodium benzoate (NaB), are perhaps the most globally acceptable preservatives that have managed to avoid the controversy associated with many of the industry’s tried-and-true preservatives.
