Any other information on results incl. tables
There was almost instantaneous destruction of the corneal epithelium. This was accompanied by corneal opacification, which over portions of the cornea was severe. Distinct iritis was observed. Well-defined conjunctival swelling with the eye about half closed and necrosis of the nictitating membrane and palpebral and bulbar conjunctivae were observed. The animal was killed one hour after instillation due to the severity of the reactions observed.
Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (irreversible effects on the eye) based on GHS criteria
- Conclusions:
- In an eye irritation study (reliability score 2), which was comparable to OECD 405, Dequest 2060s (DTPMP acid) was immediately corrosive to the eye of a rabbit. Additional rabbits were not tested due to the severity of the reaction.
