O-Leen 26 is a 100% bio-based, upcycled Ethyl Hexanediol designed for sustainable, high-performance personal care formulations. While petrochemical-derived versions have a trusted history in Asian beauty markets, O-Leen 26 introduces a green chemistry alternative upcycled from sugar cane waste and molasses via a fully traceable, BonSucro certified supply chain.
This multi-functional diol acts simultaneously as an antimicrobial booster, humectant, emollient, and pigment dispersant. It allows cosmetic chemists to lower formulation costs while easily transitioning to clean, self-preserving, or preservative-free product claims.
Key Benefits & Performance Data
Advanced Antimicrobial & Preservation Boosting
- 2x Better Performance: Delivers double the antimicrobial efficacy of standard Pentylene Glycol (A-Leen 5), confirmed by rigorous MIC testing against 5 key microorganisms.
- Microbiome-Friendly Alternative: In vitro data proves it is significantly gentler on the skin microbiome than Phenoxyethanol, protecting the natural balance of 4 major commensal skin bacterial strains.
- Broad-Spectrum Protection: At higher usage levels, it provides robust broad-spectrum protection
Superior Skin Hydration & Sensory Benefits
- High-Performance Moisturizing: Outperforms traditional Pentylene Glycol. In vivo corneometer testing (20 volunteers) proved a 19% hydration increase versus a placebo after 30 minutes, and a 31% hydration increase in comprison to untreated skin.
- Anti-Soaping Effect: Eliminates the undesirable “whitening” or soaping effect during the application of O/W creams and lotions.
- Pigment & DHA Booster: Enhances the performance and stability of self-tanning Dihydroxyacetone (DHA) and acts as an excellent wetting and dispersing agent for cosmetic pigments.
Formulation guidelines
- Phase Addition: Easily incorporate O-Leen 26 directly into the water phase. In emulsions best to add after emulsification.
- System Compatibility: Performs exceptionally well across O/W emulsions, W/O emulsions, micellar waters, gels, and surfactant-based rinse-off products without impacting foam stability.
Synergistic Preservative Boosters
To achieve optimized hurdle technology and self-preserving systems, pair O-Leen 26 with:
- Natural Diols: A-Leen 5 (Pentylene Glycol) & A-Leen 6 (1,2-Hexanediol)
- Organic Acids & Aromas: p-Anisic Acid, Sodium Benzoate, and A-Leen Aroma 3 (Phenylpropanol)
