REMOVAL OF TEST SUBSTANCE
- Washing (if done): not rinsed

SCORING SYSTEM: 1) subjective numerical according to OECD Guideline 405 (corneal, iridic and conjunctival irritation (redness/chemosis)).
2) Approx. Draize score (J. Pharmacol. Exp. Ther. 82, 1944). This score was calculated with the following formula: (5 * corneal opacity grade * area of opacity grade) + (5 * iridial injury grade) + 2 * (conjunctival redness grade + chemosis grade + discharge grade).

TOOL USED TO ASSESS SCORE: fluorescein

Irritant / corrosive response data:

Instillation of 0.1 ml of the test substance in one of the eyes of each of three albino rabbits resulted in adverse effects to the conjunctivae only. Approximately 60 min after exposure, one rabbit showed slight conjunctival redness and slight chemosis, which resolved within 24 hours.
All three animals showed slight lacrimation on day 0.
No adverse effects to the cornea and the iris were observed in any of the animals during the entire observation period. Treatment of the eyes with fluorescein 24 hours after instillation of the test substance did not reveal any corneal epithelial damage.

Other effects:

No signs of systemic intoxication were observed in any of the rabbits.

Applicant's summary and conclusion

Interpretation of results:

not irritating

Remarks:

Migrated information Criteria used for interpretation of results: EU

Conclusions:

According to the EU criteria for classification and labelling of dangerous substances, the test substance need not be labelled as an eye irritant.

Executive summary:

A sample of CR 733-S was tested in the rabbit acute eye irritation/corrosion test, performed according to OECD Guideline 405, 1987. Instillation of 0.1 ml of the test substance in one of the eyes of each of three albino rabbits resulted in adverse effects to the conjunctivae only. Approximately 60 min. after exposure, one animal showed slight reddening of the eyelids and slight chemosis, which resolved within 24 hours. No other adverse eye effects were observed in the treated animals, except for slight lacrimation on day 0.

Based on the estimated Draize score (1944) of 3.3 (60 min), the test substance should be classified as minimally irritating according to the scheme of Kay and Calandra (1962).

According to the criteria laid down in Annex VI of the EEC Council Directive 67/548/EEC (amended by Directive 83/467/EEC), and outlined in 1272/2008/EC (CLP/EU-GHS), the test substance need not be labelled as an eye irritant.
