This document specifies a method for determining the total content of the following cyclosiloxanes in chemicals for the leather tanning industry:
— octamethylcyclotetrasiloxane (D4);
— decamethylcyclopentasiloxane (D5);
— dodecamethylcyclohexasiloxane (D6);
This method requires the use of gas chromatography (GC) equipped with a single quadrupole mass spectrometer (MS) to identify and quantify the cyclosiloxanes.
