Surface active agents - Determination of foamability and degree of foamability - Circulation test method

This document specifies a method for the determination of foamability and degree of foamability of surface active agents by means of a circulation equipment, whereby the solution of the surface active agent is under fast circulation.
The method is applicable to many surface active agents, especially for low and medium foaming surface active agents and products containing surface active agents.

Grenzflächenaktive Stoffe - Bestimmung der Schäumfähigkeit und des Verschäumungsgrades - Zirkulations-Prüfverfahren

Dieses Dokument legt ein Verfahren zur Bestimmung der Schäumfähigkeit und des Verschäumungsgrades von grenzflächenaktiven Stoffen mit Hilfe einer Umwälzeinrichtung fest, wobei die Lösung des grenzflächenaktiven Stoffes schnell umgewälzt wird.
Das Verfahren gilt für viele grenzflächenaktive Stoffe, besonders für schwach und mittelmäßig schäumende grenzflächenaktive Stoffe und für Produkte, die grenzflächenaktive Stoffe enthalten.

Agents de surface - Détection de l'aptitude au moussage et du taux de moussage - Méthode par circulation

Le présent document spécifie une méthode de détermination de l'aptitude au moussage et du taux de moussage des agents de surface au moyen d'un système de circulation permettant de soumettre la solution d'agent de surface à une circulation rapide.
La méthode est applicable à beaucoup d'agents de surface, et tout particulièrement aux agents de surface faiblement ou moyennement moussants et aux formulations contenant des agents de surface.
