Beauté by Roquette® LS 007 is a liquid solution engineered to reduce the concentration of listed preservatives while maintaining high-performance antimicrobial support. It leverages a specific synergy between an organic acid, a non-ionic surfactant, and an essential oil to inhibit bacteria, yeasts, and molds. It utilizes Gluconic Acid to regulate pH and provide mild chelation, Caprylyl/Capryl Glucoside to act as a natural surfactant and carrier, and Lemongrass Leaf Oil for its inherent antimicrobial and aromatic properties.
Key Benefit: A multifunctional “Booster-Solubilizer” that increases the performance of listed preservatives while providing the necessary surfactant backbone to keep essential oils stable in water.
Performance & Synergistic Strategy
The blend is designed to work as a “Hurdle Technology” catalyst:
-
Microbial Sensitization: The glucoside component helps lower the surface tension of microbial cell walls, making them more permeable to other antimicrobial agents.
-
Acidic Stabilization: Gluconic acid provides a gentle acidifying effect, ensuring that other preservatives (like Sodium Benzoate) stay in their most active, undissociated state.
-
Natural Aromatic Shield: The Lemongrass oil provides a botanical defense layer and helps mask the base odors of raw materials.
-
Enhanced Solubility: Unlike many botanical boosters, this blend is soluble in water up to 1.5%, allowing for clear aqueous formulations without heavy synthetic solubilizers.
- Surfactant Compatibility: Compatible with anionic and cationic surfactants, as well as ethanol up to 10%.
