Administrative data
- Endpoint:
- eye irritation: in vivo
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 1987-04-07 to 1987-04-10

- other: Well documented OECD 405 study.
Cross-reference
- Reason / purpose for cross-reference:
- read-across source
Reference
- Endpoint:
- eye irritation: in vivo
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- other information
- Justification for type of information:
- Justification for the read-across from the introduced read-across supporting substance (CAS 67938 -21 -0) to the registration substance:
The introduced read-across supporting substance (CAS 67938-21-0) is structurally related to the registration substance. Both substances are fatty acid esters of polyglycerols, the only diffence being that the introduced read-across source substance (CAS 67938-21-0) is synthesized by using isostearic acid as fatty acid while the registration substance by using stearic acid.
Both substances are expected to undergo enzymatic hydrolysis resulting into the release of polyglyerols and the corresponding fatty acids (isostearic acid for the read-across supporting substance and the stearic acid for the registration substance. Isostearic acid as well as the stearic acid are well-investigated substances and occurs also endogenously. No difference in the eye irritation property can be reliably derived. - Reason / purpose for cross-reference:
- assessment report
- Interpretation of results:
- GHS criteria not met
- Executive summary:
No classification is warranted for the registration substance based on the read across data.

- Species:
- rabbit
- Strain:
- New Zealand White
Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- not required
- Amount / concentration applied:
- 0.1 mL
- Duration of treatment / exposure:
- 24 h
- Observation period (in vivo):
- up to 72 hours
- Number of animals or in vitro replicates:
- 3
- Details on study design:
- The test material was tested for primary eye irritation in three New Zealand albino rabbits according to OECD test guideline 405. The animals had no ocular abnormalities. 0.1 mL of undiluted test substance was applied once to the conjunctival sac of the left eyes of three rabbits. The untreated eye served as a respective control. The exposure period was 24 hours. 24 hours after instillation and at all the designated examination times at which corneal examination with fluorescein sodium took place, the treated eyes were washed out thoroughly with isotonic saline at approx. 37°C. The eyes were also examined for corneal lesions under UV light after instillation of one drop of 0.01 % fluorescein-sodium solution.

The other two animals showed blood vessels definitly injected. 24 hours after application some definitely hyperaemic blood vessels were still present in one animal. From 48 hours p.a. all signs of irritation were reversible.
Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Based on the results from this OECD 405 study technical grade of test substance is not irritating to eyes and thus not subject to labeling requirements.
