Results of detailed PBT / vPvB assessment
Persistence
Evidence of non-P / non-vP properties
Screening criteria
- Not P and not vP based on: readily biodegradable
- Remark:
- The substance is not readily biodegradable. However, is not stable in water . In tap water and in buffer solution (pH9) a complete hydrolysis/condensation is observed. Therefore N,N-Dimethyl-3-(trimethoxysilyl)propylamine (CAS 2530-86-1) is not persistent under environmental relevant conditions.
Conclusion: the Substance N,N-Dimethyl-3-(trimethoxysilyl)propylamine (CAS 2530-86-1) is neither a “PBT” nor a “vPvB” substance. - Not P and not vP based on: other screening test(s) (e.g. enhanced ready biodegradability, inherent biodegradability test) under valid conditions
- Remark:
- The substance is not readily biodegradable. However, is not stable in water. In tap water and in buffer solution (pH9) a complete hydrolysis/condensation is observed. Therefore N,N-Dimethyl-3-(trimethoxysilyl)propylamine (CAS 2530-86-1) is not persistent under environmental relevant conditions.
Conclusion: the Substance N,N-Dimethyl-3-(trimethoxysilyl)propylamine (CAS 2530-86-1) is neither a “PBT” nor a “vPvB” substance.
Criteria based on Annex XIII of REACH
Other evidence of non-P / non-vP properties
- Remark:
- The substance is not readily biodegradable. However, is not stable in water (Henkel, 16-17662-5). In tap water and in buffer solution (pH9) a complete hydrolysis/condensation is observed. Therefore N,N-Dimethyl-3-(trimethoxysilyl)propylamine (CAS 2530-86-1) is not persistent under environmental relevant conditions.
Conclusion: the Substance N,N-Dimethyl-3-(trimethoxysilyl)propylamine (CAS 2530-86-1) is neither a “PBT” nor a “vPvB” substance.
Further information for the PBT assessment is necessary
