ISO 19619:2018 specifies an analytical procedure for the determination of free propylene oxide in surfactants which are synthesized from propylene oxide copolymers. The method is appropriate for the qualitative and quantitative determination of propylene oxide groups in propylene oxide adducts, polyethers and polyglycol esters by headspace gas chromatography (HS-GC) with a flame ionization detector (FID) based on external procedure. Gas chromatography-mass spectrometry (GC-MS) is used for the co...view more

This Technical Specification sets requirements for bio-based surfactants in terms of properties, limits, application classes and test methods. It lays down the characteristics and details for assessment of bio-based solvents surfactants as to whether they:
- are fit for purpose in terms of performance related properties;
- comply with the requirements regarding the health, safety and environment which apply to general surfactants;
- are derived from a certain minimum percentage of biomass; and
-...view more

This International Standard provides a method for the determination of 1,4-dioxane residues in
surfactants which are synthesized from epoxyethane, such as alkyl ether sulfates and alcohol ethoxylates.
The method is applicable for samples containing 1,4-dioxane more than 5 mg/kg. For samples containing
1,4-dioxane more than 100 mg/kg, the sample solutions should be diluted to appropriate concentration.

This International Standard specifies a method for the determination of the polyethylene glycol (PEG)
content in aromatic and aliphatic non-ionic surface active agents of the type R-(O-C2H4) n OH; where n
is the mean ethylene oxide (EO) value. It is applicable to all ethoxylated products soluble in methanol
or methanol/water mixture. This method applies to PEG concentrations as mass fraction greater than
or equal to 0,1 %. This International Standard is not applicable to PEG whose molar mass...view more

For samples containing 1,4-dioxane more than 100 mg/kg, the sample solutions should be diluted to appropriate concentration.

ISO 16560:2015 specifies a method for the determination of the polyethylene glycol (PEG) content in aromatic and aliphatic non-ionic surface active agents of the type R-(O-C2H4) n OH; where n is the mean ethylene oxide (EO) value. It is applicable to all ethoxylated products soluble in methanol or methanol/water mixture. This method applies to PEG concentrations as mass fraction greater than or equal to 0,1 %. This International Standard is not applicable to PEG whose molar mass is lower than 40...view more

ISO 17283-1:2014 specifies a method for the determination of monochloroacetic acid (monochloroacetate) and dichloroacetic acid (dichloroacetate) in surfactants by HPLC method. The method applies for anionic surfactants such as alkyl (phenyl) ethoxylated carboxylate (AEC) or amphoteric surfactants such as alkyl imidazoline carboxylate, alkyl dimethyl betaine, and fatty acetyl propyl dimethyl betaine. The limit of detection (LOD) is ≤0,3 µg/ml for monochloroacetic acid and ≤0,2 µg/ml for dichloroa...view more

The method applies for anionic surfactants such as alkyl (phenyl) ethoxylated carboxylate (AEC) or amphoteric surfactants such as alkyl imidazoline carboxylate, alkyl dimethyl betaine, and fatty acetyl propyl dimethyl betaine. The limit of detection (LOD) is ≤0,01 µg/ml for monochloroacetic acid and ≤0,05 µg...view more

ISO 4317:2011 specifies two titration methods (volumetric and coulometric) using Karl Fischer reagent for the determination of the water content of surface active agents and detergents. These methods are applicable to products in the form of powders, pastes and solutions. They are applicable only if so indicated in the specific standard for each product. As alkaline compounds react with Karl Fischer reagent, the methods give values which are too high in the case of samples containing alkali meta...view more
