Sepicide G is a natural-origin preservation system based on Ethyl Lauroyl Arginate HCl (LAE®) in a glycerin carrier. LAE is an amino acid-derived cationic surfactant synthesized from three natural building blocks: L-arginine, lauric acid (derived from palm or coconut oil), and fermented ethanol. It represents a biodegradable, sustainable solution for modern microbial control in personal care.
Key Benefits and Performance
-
Broad-Spectrum Activity: Demonstrates high efficacy at low concentrations against Gram-positive and Gram-negative bacteria, yeasts, and moulds via cell membrane disruption.
-
pH-Independent Performance: Maintains stable antimicrobial activity across a wide pH range
-
Targeted Efficacy: Highly active against Malassezia furfur, supporting anti-dandruff and scalp-health claims.
-
Multi-Active Profile: Offers documented anti-acne and deodorizing properties, while its cationic nature provides skin and hair conditioning/smoothing effects.
Formulation Guidelines
-
Regulatory Limits: Maximum 0.4% active substance in cosmetic products; 0.15% in mouthwashes (EU Annex V). Note: Prohibited in lip, oral (except mouthwash), and spray products.
-
Ionic Considerations: As a cationic ingredient, it may interact with anionic surfactants or thickeners, which can lower efficacy.
-
Formulation Stability: Best used in non-ionic or cationic systems, or combined with other agents for synergistic effects in complex anionic environments.
