EUXYL K 340 is fully effective both in anionic as well as cationic systems. High pH values (> pH 8.0) should be avoided. Acidic pH values have no negative influence on the effectiveness. EUXYL K 340 proved to have good chemical compatibility with anionic surfactants such as sulphates, ether sulphates and sulphosuccinates, as well as with non-ionogenic surfactants. Ethoxylated surfactants may lead to loss of effectiveness.
