Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

From available in vitro and in vivo genotoxicity assays, it can be summarized that n-butyl cyanoacrylate is not genotoxic. A commercial formulation containing 97% of n-butyl cyanoacrylate was considered to be non-mutagenic in strains of Salmonella typhimurium and extracts from the polymerized material were considered non-clastogenic in cultured human lymphocytes and in mouse bone marrow.



Short description of key information:
- REACH_negative | S. typhimurium TA 1535, TA 1537, TA 98 and TA 100 | OECD 471 | with and without |  #key study#
- REACH_negative | human lymphocytes | OECD 473 | with and without |  #key study#
- REACH_negative | S. typhimurium TA 100, TA 1535, TA 1537 | Ames Test | - | 
- REACH_negative | mouse (male/female) | OECD 474 | Polymerised Indermil#key study#

Endpoint Conclusion: No adverse effect observed (negative)

Justification for classification or non-classification

Based on the overall weight of evidence, it was concluded that n-butyl cyanoacrylate is not considered to be genotoxic and thus needs no classification and labelling.
