E-Leen 8 is a specialized, liquid-form caprylyl glycol stabilized with small amounts of glycerin and water. Unlike standard caprylyl glycol, which often requires melting, this version remains liquid at ambient temperatures, making it ideal for cold processing, pumping, and continuous production.
Key Benefit: Provides pH-independent, broad-spectrum protection while eliminating the need for heating equipment during formulation.
Performance & Biological Activity
- Broad-Spectrum Efficacy: Effective against bacteria, yeasts, and molds but very often part of a broader hurdle approach, depending on packaging type
- Challenge Test Data: At 0.75% in an O/W emulsion, it can create a self-preserving formulation meeting ISO 11930 Criteria A.
- Synergistic Boosting: Shows enhanced efficacy when paired with phenylpropanol (A-Leen Aroma-3), achieving Criteria A at lower total concentrations.
- Skin Humectancy: Corneometry data confirms moisturizing activity (tested at 1.3% in almond oil).
- Surface-Active Properties: Offers mild wetting properties that assist in emulsion formation and surface wetting.
Formulation & Handling Guidelines
E-Leen 8 is designed for manufacturing efficiency but requires attention to solubility limits.
