General description

ECO Brij® L4, also known as polyethylene glycol lauryl ether, is a bio-based, nonionic surfactant manufactured from naturally occurring straight-chain lauryl alcohol. This detergent, derived from natural sources, provides various functional advantages, such as detergency, emulsification, and wetting, making it suitable for a range of applications in biochemical and biological research.
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".

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

Physical properties

The ECO Brij series of ethoxylated fatty alcohols are non-ionic surfactants manufactured using renewable sources. ECO Brij L4 is a mixture of tetraethylene glycol alkyl ethers, primarily dodecyl (C12) ether. The alkyl ether profile of ECO Brij L4 may differ lot-to-lot due to natural variability in the lipid starting material (palm oil).
