In January the European Chemicals Agency expanded the Candidate List of substances of very high concern (SVHC). Four hazardous chemicals were added to the Candidate List, which now contains 223 entries for chemicals that can harm people or the environment. Companies are now responsible for providing sufficient information to their customers and consumers. Developing analytical techniques to monitor these chemicals is the first step.
At ADKL Labs we have already worked on the identification and monitoring of two of the four newly added hazardous chemicals. Please find below a summary of information related to their analysis by GC-MS/MS.
Please contact ADKL Labs if you would like to learn more.
Details for two of the newly added substances:
| # | Substance name | EC number | CAS number | Reason for inclusion | Examples of use(s) |
| 1 | 6,6′-di-tert-butyl-2,2′-methylenedi-p-cresol | 204-327-1 | 119-47-1 | Toxic for reproduction (Article 57 c) | Rubbers, lubricants, adhesives, inks, fuels |
| 2 | tris(2-methoxyethoxy)vinylsilane | 213-934-0 | 1067-53-4 | Toxic for reproduction (Article 57 c) | Rubbers, plastics, sealants |
