Irritant / corrosive response data:
No irritation effect observed on all animals. The primary irritation index was 0 when applied to intact skin.
No destructions or irreversible alterations of the treated skin were observed. No corrosive effect was evident on the skin.
Other effects:
Coloration: in the area of application a clear visible brownish disocloration of the test skin was observed which could be related to effects of the test article.
Toxic symptoms / mortality: no acute symptoms were observed during the test period and no mortality occurred.
Interpretation of results:
GHS criteria not met
Conclusions:
Based on the test results, the tested item is to be considered as non-irritant to the skin of rabbits.
Executive summary:

The primary irritation score was assessed following OECD 404.

The results show no irritation on rabbit skin therefore the tested item is to be considered as non-irritant to skin under Regulation EC 1272/2008 .

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

Endpoint conclusion
Endpoint conclusion:
adverse effect observed (irritating)

Respiratory irritation

Endpoint conclusion
Endpoint conclusion:
no study available

Additional information

Based on the results the tested substance could ne considered not irritant for the skin and irritant for eyes.


Justification for selection of skin irritation / corrosion endpoint:
The study was performed on a tested substance with a higher content of active ingredient.

Justification for selection of eye irritation endpoint:
The study was the most complete and assessed the effect on cornea, iris and conjunctiva.

Effect level: empty

Endpoint conclusion: Adverse effect observed

Justification for classification or non-classification

No classification for skin irritation/corrosion is warranted under Regulation EC n. 1272/2008

Classification for eye irritation/corrosion is warranted under Regulation EC n. 1272/2008: H319, Causes serious eye irritation
