EU-LRA highlights the Triton X-100 ban affecting medicinal products and medical devices in the EU 

Substances under the trade name ‘Triton X-100’ (CAS: 9002-93-1), covered by the group entry “4-(1,1,3,3-tetramethylbutyl)phenol, ethoxylated” (4-tert-OPnEO), have been identified in the EU as substances of very high concern (SVHC) due to their endocrine disrupting properties. The OPE substances (including Triton X-100) were placed in the Candidate list (Entry) and later in the Authorisation list (Annex XIV, Entry 42, on 13 June 2017) with a latest application date on 4 July 2019 and a sunset date on 4 January 2021. Concerning medicinal products and medical devices used for the diagnosis, treatment or prevention of COVID-19 the latest application date is 22 June 2022 and the sunset date 22 December 2023.  After the sunset date the use of Triton X-100 is no longer allowed in the EU/EEA and affected companies should approach as soon as possible their enforcement authorities and start preparing their application. There are some generic exemptions from the authorization requirement listed on the EC webpage (Authorisation - ECHA (, however use of Triton X-100 and other OPEs in medicinal products like vaccines and gene therapy products is no longer accepted without authorization. The authorization applications submitted for use of OPEs (including medicinal products) are available at Adopted opinions and previous consultations on applications for authorisation - ECHA ( It is highly recommended that the use of OPE in manufacture of medicinal products is replaced with a safer alternative substance or technology.”
