General description
Dodecamethylcyclohexasiloxane belonging to the class of cyclic volatile methylsiloxanes is identified as a potent environmental contaminant, most prominently found in biota, biosolid samples, soil, sediment samples, wastewaters, etc. These compounds are used as fragrance carriers or solvents in household products, personal care products, cleaning agents and as precursors in the manufacture of silicone polymers.
This compound is listed in the SVHC (Substances of very high concern) candidate list of ECHA (European Chemicals Agency)
Application
Dodecamethylcyclohexasiloxane may be used as an analytical reference standard for the quantification of the analyte in the following:
- Silicone emulsions using gas chromatography with flame ionization detection (GC-FID).
- Biota and wastewater samples using gas chromatography coupled to mass spectrometry (GC-MS).
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
