Surface active agents - Determination of cloud point of non-ionic surface active agents obtained by condensation of ethylene oxide EN 1890:1999

Publication date:   Apr 16, 2000

Scope

This European Standard specifies methods for the determination of the cloud point of solutions of non-ionic surface active agents obtained by the reaction of ethylene oxide with a hydrophobic base molecule. This standard primarily applies to surfactants obtained by reaction of ethylene oxide with hydrophobic base molecules, such as fatty alcohols, fatty acids, long-chain alkylphenols, fatty amines, fatty acid esters of sugar derivatives among other ethoxylated non-ionic surfactants, which are by far the most commonly used.
