应用
Polysorbate 40 has been used in a study to assess the determination of iodide in urine based on a chemiluminescence system. It has also been used in a study to investigate the delivery of astaxanthin and canthaxanthin to HepG2 cells. Also used as oil-in-water emulsifiers in pharmaceuticals, cosmetics, cleaning compounds. 备注
Store in cool. Keep container tightly closed in a dry and well-ventilated place. Store away from oxidizing agent. 基本信息 MDL

产品说明 一般描述 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".
Polyoxyethylenesorbitan monopalmitate, or TWEEN 40, is a non-ionic detergent. 应用 Non-ionic detergent used for cell lysis, nuclei isolation and cell fractionation.
Polyoxyethylenesorbitan monopalmitate, or TWEEN 40, has been used in a study to assess the determination of iodide in urine based on a chemiluminescence system. It has also been used in a study to investigate the delivery of astaxanthin and canthaxanthin to HepG2 cells. 特点和优势 - 100 % Renewable
- 100 % Bio-based
- Certified to the USDA BioPreferred Program
- Lower carbon footprint than petrochemical-based versions
