- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 0.1 ml - Duration of treatment / exposure:
- First and second tests: one application
Third test: only rinsing - Observation period (in vivo):
- First test: observations were recorded at 1 h and I, 2, 3, 4 and 7 days after instillation and, in cases where lesions persisted, also at later stages.
- Number of animals or in vitro replicates:
- groups of 6
- Details on study design:
- First test:
6 rabbits: 0.1 ml was instilled and observations were recorded at 1 h and I, 2, 3, 4 and 7 days after instillation and, in cases where lesions persisted, also at later stages.
Second and third tests:
Test materials showing any degree of irritancy more severe than that classified as slightly irritant (see below) in this first test were similarly instilled into another group of six rabbits, and the eyeball and related structures were rinsed 30 sec after the instillation. If the material was still found to be irritant, a third test was run with rinsing after 4 sec.
REMOVAL OF TEST SUBSTANCE
- Washing (if done): in the second and third tests
SCORING SYSTEM: since the Cosmetic and OECD protocols specify no numerical system for the scoring and interpretation of results, a scoring system based on the AFNOR recommendations was used throughout, with modifica¬tions where appropriate to enable direct comparisons between the protocols to be made.

Applicant's summary and conclusion
- Interpretation of results:
- Category II
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The substance is considered as very irritant based on the results of the study.
- Executive summary:
The ocular irritancy of 56 chemicals was tested in the rabbit eye, with and without rinsing, using a procedure that complied with the main requirements of three protocols, namely those proposed by the Association Francaise de Normalisation (AFNOR) in 1982 and by the Organisation for Economic Cooperation and Development in 1979 for the testing of chemicals and that published by the French authorities(Journal Officiel21 April 1971, p. 3862;ibid5 June 1973, p. 3953) for the testing of cosmetics and toiletries. The results obtained were used to establish the extent to which the assessment of a chemical's irritation potential was affected by the differences between the three protocols in respect of the observation times prescribed, the inclusion and timing of rinsing, the number of animals used and the interpretation procedure. Conclusions were also drawn about the influence of the physical state and pH of a material on its potential irritancy and about the level of irritancy that necessitates the use of eye protection.
The experience has shown that the various ocular irritation indices are not a particularly helpful guide in themselves; a graduated scale of irritancy taking into account both these indices and the reversibility of the lesions seems a preferable basis for the interpretation of results.
