- Although the EU risk assessment report is secondary literature, all data and risk assessment for the human, health and the environment have been evaluated and reviewed by Finland prior to publication. The risk assessment report has been submitted to final approval and published in the Official Journal of the European Union C157/10 dated on 21.06.2008. Thus, it is considered the information reported are reliable with the restrictions that reliability of the data presented has not been assessed again.

Applicant's summary and conclusion
- Interpretation of results:
- Toxicity Category IV
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Considering the lower limit of the range dermal LD50 (1500 mg/kg bw), EPTAC is classified as Acute tox. 4 (H312, harmful in contact with skin) according to the CLP regulation (No. 1272/2008 EC) and as harmful in contact with skin (Xn, R21) according to the Directive 67/548/EEC.
- Executive summary:
In a dermal acute study (Shellengberger, 1962), two groups of three rabbits each were administered dermally either 1500 or 3000 mg/kg 2,3-Epoxypropyltrimetylammonium Chloride (EPTAC) in an aqueous solution. There was no information about the methodology used to expose the animals to the test substance (duration, type of patch).
In the lower dose group (i.e.1500 mg/kg bw) one rabbit died after 7 days of administration whereas in the higher dose group (i.e.3000 mg/kg bw), two rabbits died in 5 h or 2 days. The LD50was estimated to be between 1500 – 3000 mg/kg bw.
Considering the lower limit of the range dermal LD50(1500 mg/kg bw), EPTAC is classified as Acute tox. 4 (H312, harmful in contact with skin) according to the CLP regulation (No. 1272/2008 EC) and as harmful in contact with skin (Xn, R21) according to the Directive 67/548/EEC.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
