E-Leen® 58 Gold

E-Leen 58 GOLD is a multifunctional blend of Pentylene Glycol and Caprylyl Glycol enriched with purified citrus bioflavonoids. The bioflavonoid component is upcycled from food production, adding a sustainable antioxidant functionality to the established antimicrobial and moisturizing benefits of the alkanediol base.

Key Benefit: Functions as a sustainable antioxidant (in vitro data) while providing broad-spectrum protection.

Performance & Multifunctional Benefits

  • Antioxidant Activity: DPPH radical scavenging data confirms its ability to neutralize free radicals, positioning it as an active “detox” ingredient.
  • Broad-Spectrum Efficacy: Effective against bacteria, yeasts, and molds; met ISO 11930 Criteria A in an O/W emulsion at pH 5.5.
  • Self-Preserving Support: The antimicrobial boosting effect is particularly suited to O/W emulsions and cleansing products.
  • Clinically Proven Hydration: 4-hour corneometry data demonstrates a statistically significant increase in skin hydration in an O/W emulsion at 1, 2, and 4 hours after application.

Formulation & Handling Guidelines

E-Leen 58 GOLD requires careful pH management and specific addition timing for optimal performance.

Water solubility is limited to 0.75% in demineralised water; a solubiliser is recommended for clear and storage-stable aqueous solutions. The blend is also miscible with lower alcohols and polar vegetable oils.

It is compatible with low and neutral pH values; however, high pH and oxidising agents may cause deactivation and yellow discolouration, making this blend unsuitable for alkaline formulations.
