12 Principles of Green Chemistry: Principle 7—A raw material or feedstock should be renewable rather than depleting whenever technically and economically practicable.
12 Principles of Green Chemistry: Principle 10—Chemical products should be designed so that at the end of their function they break down into innocuous degradation products and do not persist in the environment.

| Application: | Brij®L23 is a detergent used for measuring the concentration of carbon black in lung tissues. It has also been used for selective and rapid solubilization of microbial membrane aldehyde dehydrogenase. Additionally, the product has also been used for assessing whether acrolein could lead to pro-enzyme activation by using gelatin zymography. |
| Biochem/physiol Actions: | Brij® L23 also referred to as Brij 35 or Polyoxyethylene (23) lauryl ether is a non-ionic detergent that lowers the non-specific protein adsorption and reduces electroosmotic pumping drastically. This allows the pH to be varied without adversely affecting the flow rate. It also used as a nonionic surfactant that decreases the absorbance of the blank, inhibits turbidity as well as provides linearity. |
| Features and Benefits: | • 100 % Renewable • 100 % Bio-based • Certified to the USDA BioPreferred Program • Lower carbon footprint than petrochemical-based versions |
| General description: | 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. |

| Other Notes: | Non-ionic polyoxyethylene ether. Used for selective and rapid solubilization of microbial membrane aldehyde dehydrogenase. |
| Physical properties: | The ECO Brij series of ethoxylated fatty alcohols are non-ionic surfactants manufactured using renewable sources. ECO Brij L23 is a mixture of tricosaethylene glycol alkyl ethers, primarily dodecyl (C12) ether. The alkyl ether profile of ECO Brij L23 may differ lot-to-lot due to natural variability in the lipid starting material (palm oil). |
