Determination of cyclic volatile methylsiloxanes in personal care products by gas chromatography

ConclusionThis report demonstrates that an approach to determine cVMS levels in personal care products is to perform an emulsion break on the sample, isolate the nonpolar phase from the emulsion break and treat with a silylation reagent to abate potential in situ formation of cyclics during the course of GC‐FID analysis. Round robin studies conducted in laboratories representing multiple siloxane manufacturers demonstrated the reliability of the GC‐FID method when measuring cVMS in PCPs down to circa 0.1%.This article is protected by copyright.
