Science
Mechanism of Action
This ingredient works on skin and in formulations by disrupting microbial cell membranes and inhibiting ergosterol synthesis, a vital component of fungal cell walls, thereby exerting antifungal and antimicrobial effects. As a surfactant, it enables water to mix with oils and dirt for effective cleansing. Additionally, it possesses properties that can modulate inflammatory pathways, contributing to anti-inflammatory effects.

Key findings
- 01 Clinical studies on arginine undecylenate, a related salt of undecylenic acid, demonstrated a Minimum Inhibitory Concentration (MIC100) as low as 0.063% against various Gram-positive and antibiotic-resistant bacteria, including MRSA, MSSA, VISA, and S. pyogenes. At 0.126%, MIC100 was achieved across 18 isolates, with Minimum Bactericidal Concentration (MBC100) observed in 7 isolates. Higher concentrations, such as 0.252%, further achieved MBC100 in 16 isolates, indicating potent antimicrobial activity.
