General description

Nonaethylene glycol monododecyl ether [C12H25O(CH2CH2O)9H] (AEO9) is a non-ionic surfactant.

Application

Nonaethylene glycol monododecyl ether has been used in a study to assess a procedure for analyzing total lipid and triacylglycerol using bovine liver tissue. It has also been used in a study to investigate how particle size of aggregates can be measured by the concentration dependence of the amplitude of the autocorrelation function.
