Surface active agents - Detergents - Determination of anionic-active matter hydrolysable and non-hydrolysable under acid conditions (ISO 2870:2009)

This International Standard specifies a method for the determination, in detergents, of anionic-active matter hydrolyzable and non-hydrolyzable under acid conditions. This active matter includes alkyl sulfates and hydroxysulfates and alkylphenol and fatty alcohol ethoxysulfates. The mean relative molecular mass of the two types of active matter must be known or previously determined, if their content is expressed as a percentage by mass. If the detergent contains any oxidizing agent, this must be destroyed before the hydrolysis.

Grenzflächenaktive Stoffe - Waschmittel - Bestimmung von sauer hydrolysierbaren und nicht-hydrolysierbaren anionaktiven Anteilen (ISO 2870:2009)

Diese Internationale Norm legt ein Verfahren zur Bestimmung von sauer hydrolysierbaren und nicht hydroly¬sierbaren anionaktiven Anteilen in Waschmitteln fest.
Diese anionaktiven Anteile umfassen Alkylsulfate und Hydroxysulfate sowie Alkylphenol  und Fettalkohol¬ethersulfate.
Die mittlere relative molare Masse der beiden Typen anionaktiver Stoffe muss bekannt sein oder vorher bestimmt werden, wenn deren Gehalt als Massenanteil in Prozent angegeben wird. Enthält das Waschmittel irgendein Oxidationsmittel, muss dieses vor der Hydrolyse zerstört werden.

Agents de surface - Détergents - Détermination de la matière active anionique hydrolysable et non hydrolysable en milieu acide (ISO 2870:2009)

L'ISO 2870:2009 spécifie une méthode de détermination, dans les détergents, de la matière active anionique hydrolysable et non hydrolysable en milieu acide.
Cette matière active comprend les alkylsulfates et les alkylhydroxysulfates, ainsi que les éthoxysulfates d'alkylphénol et d'alcool gras.

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies

(ISO member bodies). The work of preparing International Standards is normally carried out through ISO

technical committees. Each member body interested in a subject for which a technical committee has been

established has the right to be represented on that committee. International organizations, governmental and

non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
