Monitoring Study
D4, D5, and D6 levels
Silicones Europe commissioned ERM GmbH (Environmental Resources Management – ERM) to conduct a multi-year monitoring study to evaluate the effectiveness of the EU product use restriction of octamethylcyclotetrasiloxane (D4) and decamethylcyclopentasiloxane (D5) in wash-off personal care products (PCPs).
The results indicate that the D4 and D5 EU-wide mass loadings are well below the pre-restriction levels outlined in the 2018 Restriction. The D4 loadings align with the post-restriction goal of the 2018 Restriction, while D5 loadings are nearing the post-restriction goal set in the 2018 Restriction and fall within the range of goals proposed in the 2019 Restriction.
