Details of eye irritation scores (according to Draize)
Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (irreversible effects on the eye) based on GHS criteria
- Conclusions:
- Cocamidopropyl hydroxysultaine, as a 41.5% solution, is considered a severe eye irritant.
- Executive summary:
Cocamidopropyl hydroxysultaine, as a 41.5% solution (Betadet SHR), has been tested for acute eye irritation on 3 male New Zealand White rabbits, in accordance with OECD test guideline 405, and in compliance with Good Laboratory Practice.
The test article was applied as such in a single conjunctival dose of 0.1 mL in the right eye of each rabbit, the untreated eye being used as a control. Ocular examinations, grading cornea, iris and conjunctiva (redness and chemosis) reactions, were performed at 1, 24, 48, 72 hours, and on day 7, 14 and 21 after instillation of the test article.
Within the first hour following instillation, the test article induced conjunctival abnormalities including hyperhaemia ranging from grade 2 (diffuse, crimson color, individual vessels not easily discernible) to grade 3 (diffuse, deep red color), edema ranging from grade 2 to 3, redness of the bulbar conjunctivae, lacrimation and congestion and injection of the iris (grade 1).
At the observations carried out 24, 48 and 72 hours after instillation, all rabbits showed hyperhaemia ranging from grade 2 to grade 3, chemosis from grade 1 to grade 3, redness of the bulbar conjunctivae, lacrimation and congestion and injection of the iris (grade 1). Corneal opacity (grade 1) was also observed in all animals.
Some of the corneal and conjunctival abnormalities persisted up to day 14 after instillation inclusive. Conjunctival chemosis was still observed in one of the rabbits 21 days after instillation of the test article.
Based on these results, Cocamidopropyl hydroxysultaine, as a 41.5% solution, was considered a severe eye irritant.
