Laboratory analysis and determination of D4 and D5 siloxane content

Your needs: to monitor the use of D4 and D5 siloxanes in your production processes

What do we mean by Siloxanes?

The name Siloxane is derived from Silicon, Oxygen and alkane. They are a family of chemical substances composed of primarily of silicon. Usually found in cosmetic products, (makeup, crème, deodorant…) and in cleaning as a whole, in paint, etc. They are used for they particular chemical properties: they are odorless, colorless,  non-greasy, easy to apply and dry rapidly.

This family encompasses multiple categories of substances: Cyclotetrasiloxanes (D4), Cyclopentasiloxanes (D5) and Cyclohexasiloxanes (D6). The term “silicone” can also be used to refer to siloxanes.

Why analyze siloxanes?

Found in some household products, humans can de exposed to siloxanes through skin contact or by inhalation. D4 siloxanes have been classified as endocrine disruptors by the European Union due to their suspected toxicity to the human reproductive system. However, risks linked to the use of cosmetic products containing D4 siloxanes has not yet been proven. Regarding D5 siloxanes, regulatory authorities consider its use to be risk free.

Ecological concerns have been raised surrounding the use of these two substances; D4 and D5 siloxanes are suspected to be toxic to aquatic life due to the fact that they are not biodegradable in water or living tissue.

The monitoring of scientific advances relating to the use of siloxanes and their impact on human and environmental health is an important topic in the cosmetics industry. Therefore, support from a specialized laboratory will allow you to adapt your production procedures to stay in line with changes in regulations.

Our solution: to reliably analyze and quantify the presence of D4 and D5 siloxanes in your finished products to asses the risk they pose

Our analytical services for D4/D5 siloxanes

Thanks to the know-how of its team and its cutting-edge analytical fleet, FILAB laboratory is able to assist companies with analyses of D4 and D5 siloxanes and in verifying that their products comply with standards:

  • Determination and analysis of siloxane contents in your products
  • Analytical development and validation of methods for determining content in accordance with relevant ISO standards
  • R&S assistance: product substitution, reverse engineering, literature review…

D4 and D5 siloxanes are analyzable using gas chromatography (GC-MS) due to their volatility. Being organic compounds, it is possible to determine their structure using Nuclear Magnetic Resonance (NMR).
