Surface active agents - Determination of cloud point of non-ionic surface active agents obtained by condensation of ethylene oxide
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.
Grenzflächenaktive Stoffe - Bestimmung des Trübungspunktes nichtionischer, durch Anlagerung von Ethylenoxid hergestellter grenzflächenaktiver Stoffe
Diese Europäische Norm legt ein Verfahren zur Bestimmung des Trübungspunktes von Lösungen nichtionischer grenzflächenaktiver Stoffe fest, wie sie durch Reaktion von Ethylenoxid mit einem hydrophoben Ausgangsmolekül erhalten werden. Die Norm ist hauptsächlich anwendbar auf grenzflächenaktive Stoffe, wie sie durch Reaktion von Ethylenoxid mit hydrophoben Ausgangsmolekülen, wie Fettalkoholen, Fettsäuren, langkettigen Alkylphenolen, Fettaminen, Fettsäureestern von Zuckerderivaten neben anderen ethoxylierten nichtionischen grenzflächenaktiven Stoffen erhalten werden, die bei weitem am meisten verwendet werden.
Agents de surface - Détermination du point de trouble des agents de surface non ioniques obtenus par condensation d'oxydes d'éthylène
La présente norme européenne spécifie les méthodes de détermination du point de trouble des solutions d'agents de surface non ioniques obtenus en faisant réagir, par exemple, de l'oxyde d'éthylène avec un radical hydrophobe. La présente norme européenne s'applique avant tout aux agents de surface obtenus par réaction de l'oxyde d'éthylène avec des radicaux hydrophobes tels que les alcools gras, les acides gras, les alkylphénols à chaîne longue, les amines grasses, les esters d'acides gras des dérivés du sucre entre autres agents de surface non ioniques éthoxylés, qui sont de loin les plus couramment utilisés.
