US 12,767,626 B2 · Non-ionic surfactants and methods of making and using the same

Abstract

Disclosed herein are aspects of a compound according to Formula I The compounds are useful as surfactants and can be used in applications for which a surfactant is indicated. The disclosed compounds are biodegradable and do not form toxic by-products when degraded. As such, the disclosed compounds can be used as replacements for current surfactants, such as current octylphenol ethoxylates (OPEs) and nonylphenol ethoxylates (NPEs) that have toxic effects when degraded. Also disclosed are aspects of a method for making the compounds and methods for using the compounds in cell assays.
