Applications & Use Cases
  • Solubilizes fragrance oils, essential oils, and lipophilic actives into clear aqueous and hydroalcoholic systems for personal care formulations such as toners, micellar waters, and body sprays.
  • Acts as a nonionic O/W emulsifier and co-emulsifier in lotions, creams, and serums, stabilizing oil-in-water dispersions without ionic charge interactions.
  • Functions as a fragrance and surfactant carrier in HI&I cleaning products, helping disperse perfume and water-insoluble ingredients in surface cleaners and detergents.
  • Serves as a wetting agent and solubilizer in industrial and household concentrates where clear, stable single-phase liquids are required across a range of pH.
  • Used as a nonionic solubilizer for water-insoluble vitamins, plant extracts, and active ingredients in cosmetic and topical formulation work.
