24
Observation period:
At the end of the 24-hour period and 48 hours later. Scoring of irritation according to the method of Draize.
Number of animals:
3
Details on study design:
0.5 ml test substance applied on the scarified and 0.5 ml on non-scarified area, which were covered with Webril patches. Animals were immobilized in racks for the 24-hour period.

no indication of irritation
Other effects:
Not specified.
Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: other: Scoring according to Draize
Conclusions:
Since the test material produced a primary irritation index of 0 it can be considered as non-irritant and not sufficient for classification.
Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not irritating)

Eye irritation

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not irritating)

Respiratory irritation

Endpoint conclusion
Endpoint conclusion:
no study available

Additional information

Justification for classification or non-classification

Since the test material produced a primary irritation index for skin of 0 to 0.5, it can be considered as only a very slightly primary irritant and not sufficient for classification. A study with test material did not induce significant irritation of rabbits eye, implying no reason for classification as an eye irritant.
