LEMA-14A is a natural multifunctional system that leverages the synergistic antimicrobial and biological properties of Magnolol and Honokiol. While most preservatives focus only on the standard five-organism challenge panel, it comes with MIC data for an unusually wide range of 11 organisms, offering formulators a deeper layer of information for specific applications.
Key Benefit: A Multifunctional that provides anti-inflammatory and anti-lipid peroxidation activity from literature —along with preservative boosting properties on several microorganisms
Comprehensive Antimicrobial Spectrum
The antimicrobial profile is supported by exceptionally low Minimum Inhibitory Concentration (MIC) data across a diverse panel:
-
Gram-negative Bacteria: MICs for E. coli, P. aeruginosa, P. fluorescens, P. putida, K. pneumoniae, and E. gergoviae.
-
Gram-positive Bacteria: Highly effective against S. aureus and S. epidermidis.
-
Fungi & Yeast: Comprehensive coverage against one yeast (C albicans) and two moulds (A. niger, P. funiculosum)
Independent Biological Benefits
Beyond stabilization, the neolignans in LEMA-14A act as high-performance actives:
-
Anti-Inflammatory: Reduces skin sensitivity and redness.
-
Free Radical Scavenging: Provides potent antioxidant protection for both the skin and the formula.
-
Anti-Lipid Peroxidation: Prevents the breakdown of the skin’s natural sebum, making it highly relevant for anti-acne and anti-ageing claims.
Formulation & Handling Guidelines
It is generally a stable, hydrolysis-resistant liquid that requires specific temperature controls to maintain the integrity of the neolignans.
