Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The test material was not irritant to rabbit eye under the conditions of this study.
- Executive summary:
In a primary eye irritation study, according to OECD Guideline No.405, 0.1 mL of undiluted 2,2-bis(chloromethyl)trimethylene bis(bis(2-chloroethyl)phosphate) was instilled into the conjunctival sac of 3 New Zealand white rabbits (1 female, 2 male rabbits used). Animals then were observed for 3 days. Irritation was scored by the method of Draize, scale for scoring ocular irritation. The test material was not irritant to rabbit eye under the conditions of this study.
