Linatural® Ultra-1 is a synergistic blend of three bio-based components that provide broad-spectrum protection while improving the skin-feel of cosmetic formulations. By combining a nature-derived aromatic alcohol with two high-performance alkanediols, the system effectively disrupts microbial cell membranes and inhibits growth without the use of synthetic parabens or phenoxyethanol.
Key Benefit: A 100% natural “Preservative-Free” claimant that serves as a humectant, solvent, and antimicrobial in a single, clear liquid.
Performance & Synergistic Strategy
-
Broad-Spectrum Protection: The Benzyl Alcohol (sourced from Cassia) acts as the primary antimicrobial agent, while the glycols act as “boosters” by increasing the permeability of microbial cell walls.
-
Humectancy: Both 1,3-Propanediol and Pentylene Glycol are powerful humectants that provide a smooth, non-tacky moisturizing effect, often allowing for a reduction in glycerin levels.
-
Solvency: The blend acts as an excellent solvent for other lipophilic actives, helping to stabilize botanical extracts and fragrances in water-based systems.
Formulation & Handling Guidelines
Linatural® Ultra-1 is a liquid blend designed for ease of use in both hot and cold processes.
