Polyoxyethylenesorbitanmonooleate tween 80

Manufactured by Sisco Research Laboratories
Sourced in India

Polyoxyethylenesorbitanmonooleate (Tween 80) is a non-ionic surfactant commonly used as an emulsifier, solubilizer, and stabilizer in various laboratory applications. It is a viscous, yellow liquid with a mild odor. Tween 80 is soluble in water and many organic solvents, and it is primarily used to improve the solubility and stability of other compounds.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
