en.Wedoany.com Reported - Evonik's Coatings Additives business line has announced that over 95% of its active siloxane-based coating additive portfolio contains less than 0.1% Substances of Very High Concern (SVHC), ensuring these products remain suitable for coatings and inks seeking Ecolabel certification. Through continuous process optimization and the use of high-quality raw materials, the company guarantees the highest purity of its siloxane-based additives, verified by extensive analytical testing.
This development is driven by recent regulatory progress in the EU. Certain low-molecular-weight siloxanes have been classified as SVHC due to their persistence and bioaccumulation under REACH criteria. New EU hazard classes—PBT (Persistent, Bioaccumulative, and Toxic) and vPvB (very Persistent and very Bioaccumulative)—require classification and labeling of products when these substances are present at concentrations of 0.1% or higher.
Evonik's assessment shows that over 95% of its active TEGO® siloxane additive portfolio contains no or negligible levels of SVHC substances that would trigger vPvB or PBT classification. This allows customers to continue using siloxane-based TEGO® products without reformulation or switching to costly "purified" alternatives, ensuring uninterrupted compliance, consistent performance, and reliable supply.
"Our customers can rely on Evonik Coatings Additives to anticipate regulatory changes and deliver solutions that combine compliance with performance," said Kristina Meier, Global Head of the Silicone & Acetylenic Product Line at Evonik Coatings Additives. "This achievement underscores our commitment to sustainability, regulatory excellence, and making life easier for our customers and partners."
Under the latest amendment to the Classification, Labelling and Packaging (CLP) Regulation, new EU hazard classes vPvB and PBT carry labeling obligations for substances from May 2025 and for mixtures from May 2026. Any product containing more than 0.1% of a single substance classified as vPvB and/or PBT must be classified and labeled as vPvB (EUH441) and/or PBT (EUH440). Although cyclic siloxanes D4, D5, and D6 have been listed as SVHC since 2018 due to their vPvB and PBT concerns, the European Chemicals Agency (ECHA) recently expanded its SVHC list to include short-chain linear and branched siloxanes: L3 (Octamethyltrisiloxane, CAS 107-51-7), L4 (Decamethyltetrasiloxane, CAS 141-62-8), and M3T (1,1,1,3,5,5,5-Heptamethyl-3-[(trimethylsilyl)oxy]trisiloxane, CAS 17928-28-89), which were added to the Candidate List of Substances of Very High Concern due to their vPvB properties.
