A-Leen 6

A-Leen 6 is a high-purity, multifunctional alkane diol that serves as a direct green replacement for petroleum-derived 1,2-Hexanediol. It provides a bridge between different formulation phases, acting as a co-solubilizer and wetting agent to improve the stability and sensory profile of cosmetic products. Its 100% bio-based carbon content supports green claims without sacrificing performance.

Key Benefit: A versatile “clean beauty” workhorse that enhances product protection and skin hydration while maintaining a good mildness profile for sensitive skin applications.

Performance & Multifunctional Benefits

  • Preservation Boosting: Effectively reduces water activity and destabilizes microbial cell membranes, significantly increasing the “kill-rate” of primary preservatives.
  • Humectancy & Emolliency: Attracts moisture to the skin while providing a soft, smooth after-feel, unlike longer-chain glycols that can feel tacky.
  • Solubilization Support: Acts as a powerful co-solvent, helping to incorporate lipophilic actives, fragrances, or botanical extracts into aqueous systems.
  • Wetting Agent: Lowers surface tension, improving the spreadability of emulsions and the “wetting” of pigments in color cosmetics.
