Kollisolv® PEG 8000 is a high molecular polyethylene glycol (macrogol) mainly used as solvent for oral, topical and parenteral preparations. The high molecular weight PEG is soluble in water and organic solvents such as alcohols. It can be blended with other PEG molecular weights to achieve the desired properties, i.e. viscosity. Kollisolv® PEG 8000 will not become rancid and will not support microbial growth, even in aqueous solutions.

Why use Kollisolv® PEG 8000?

  • Unique properties such as low order of toxicity, solvent capabilities, blandness, water solubility
  • Soluble in water and organic solvents
  • Can be blended with other PEG molecular weights to achieve the desired properties
  • Will not become rancid and will not support microbial growth
  • Wide acceptance in pharmaceutical application for over 50 years
