General description

ECO TWEEN® 85, also known as Polyoxyethylene sorbitan trioleate, is a bio-based, nonionic detergent manufactured from a natural fatty acid. This surfactant, derived from natural sources, provides various functional advantages, such as detergency, emulsification, and wetting. Its versatility makes it well-suited for a variety of applications in biochemical and biological research, with common uses including cell lysis, protein extraction, nuclei isolation and cell fractionation.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. This product is a biobased surfactant and is aligned with the 7th principle of Green Chemistry "Use of Renewable Feedstocks" and the 10th principle "Design for Degradation".

Application

TWEEN 85 has been used in a study to assess the potential application of niosomes for the delivery of ammonium glycyrrhizinate for the treatment of inflammatory diseases. It has also been used in a study to investigate the joint-action of antifouling substances in copper-free paints.

Features and Benefits

  • 100 % Renewable
  • 100 % Bio-based
  • Certified to the USDA BioPreferred Program
  • Lower carbon footprint than petrochemical-based versions
  • High-purity chemical suitable for a wide variety of research applications
