Leucidal SF Max Powder

Leucidal® SF Max is a high-specification antimicrobial produced through the fermentation of Lactobacillus in a defined medium. It is an “optimized iteration” featuring a tightened concentration of bacteriocins—the antimicrobial peptides that drive its efficacy. The manufacturing process uses papaya-derived lysozyme to facilitate controlled cell lysis, ensuring the maximum release of these bioactive peptides for superior performance.

Key Features & Technical Benefits

  • Broad-Spectrum Efficacy: Demonstrates notably low and uniform Minimum Inhibitory Concentrations (MIC) against all five standard challenge test organisms.

  • Clinically Proven Barrier Support:

    • Hydration: Measurable improvement in hydration % after 24 hours and 4 weeks.

    • Barrier Function: Significant reduction in Transepidermal Water Loss (TEWL) after 3 weeks.

    • Skin Density: High-resolution ultrasound imaging confirmed improved skin density versus untreated skin.

  • Salicylate-Free Regulation: this Leucidal® version does not contain natural salicylates. It is exempt from EU Annex III and Annex V restrictions, making it the preferred choice for baby care (under 3 years), oral care, and spray applications.

Formulation & Handling
