Les mélanges conviennent pour la fabrication de nombreux agents tensioactifs non moussants ou réducteurs de mousse, par exemple des agents de lavage de vaisselle à la machine, des agents de rinçage clarifiants, des agents de nettoyage des bouteilles, des dispersants, des produits de nettoyage universels, des collecteurs de flottation, etc.
