DESCRIPTION
BS EN ISO 2870:2009
This standard BS EN ISO 2870:2009 Surface active agents. Detergents. Determination of anionic-active matter hydrolysable and non-hydrolysable under acid conditions is classified in these ICS categories:
- 71.100.40 Surface active agents
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.
