Full title and description

ISO 2870:2009 — Surface active agents — Detergents — Determination of anionic-active matter hydrolysable and non-hydrolysable under acid conditions. The standard specifies a laboratory method for determining the amounts of anionic-active material in detergent products that are hydrolysable and non-hydrolysable under acidic conditions, including common classes such as alkyl sulfates and ethoxysulfates.

Abstract

ISO 2870:2009 defines a quantitative analytical procedure to separate and measure anionic-active matter in detergents that is hydrolysable under acid conditions and the fraction that is not hydrolysable under those conditions. The method is applicable to common anionic surfactants found in detergents (for example alkyl sulfates, alkylhydroxysulfates, alkylphenol and fatty alcohol ethoxysulfates).

Scope

This document specifies a laboratory method for the determination, in detergents, of anionic-active matter hydrolysable and non-hydrolysable under acid conditions. It is intended for use on finished detergent formulations and ingredient samples where the identification and quantification of anionic-active fractions under acidic hydrolysis is required for quality control, regulatory reporting or formulation assessment.

Key topics and requirements

• Definition of anionic-active matter fractions that are hydrolysable under acidic conditions and those that are not.
• Sample preparation and acid-hydrolysis procedure suitable for detergent matrices.
• Analytical separation and quantification steps to report hydrolysable vs non-hydrolysable anionic-active contents.
• Applicability to common anionic surfactant types: alkyl sulfates, alkylhydroxysulfates, alkylphenol ethoxysulfates and fatty alcohol ethoxysulfates.
• Reporting requirements and expression of results (mass fractions/percentages in the sample).

Typical use and users

Manufacturers of detergents and surfactant raw materials, quality-control and testing laboratories, regulatory bodies assessing composition and labeling, formulation chemists, and environmental testing laboratories use this standard to quantify anionic-active content and to ensure product compliance and consistent production quality.

Related standards

ISO 2870:2009 replaces and updates the earlier ISO 2870:1986 (withdrawn). It is part of the broader family of ISO standards addressing surface-active agents and detergent testing methods; related ISO/TC 91 publications cover other test methods and vocabulary for surfactants and detergents.
