    Kolliphor® RH40

      Non-ionic oil-in-water solubilizer and emulsifying agent

      Derived from hydrogenated castor oil and ethylene oxide, Kolliphor® RH40 is used as a non-ionic oil-in-water solubilizer and emulsifying agent. It is particularly suitable for fat-soluble vitamins and demonstrates exceptional chemical stability. This tried-and-trusted solubilizer scored highest on resistance to enzymatic digestion in a study of various surfactants, highlighting its potential to enhance patient safety. Kolliphor® RH40 is widely used in self-emulsifying drug delivery systems (SEDDS) or microemulsifying systems (SMDDS) in combination with a co-solubilizer and/or co-solvent. What’s more, Kolliphor® RH40 is almost tasteless – making it ideal for oral applications.

    Why choose Kolliphor® RH40?
    Widely used solubilizer, approved by all relevant regulatory bodies
    Particularly suited for aqueous solutions of fat-soluble vitamins
    Chemically stable and practically tasteless – perfect for oral applications
    Suitable for SEDDS and SMDDS
