The primary irritation index as the measure of the acute skin irritation provoked by the substance is defined as the average of all the ratings found after 24 and 72 hours on the intact and slightly scarified skin. Compounds producing combined averages (primary irritation indexes) of 2 or less are only mildly irritating; whereas those with indexes from 2 to 5 are moderate irritants, and those v/ith scores above 6 are considered severe irritants.

The primary irritation index of the tested item was 0.

Interpretation of results:
GHS criteria not met
Conclusions:
The primary irritation index as the measure of the acute irritation to the skin of rabbits was found to be 0.
Therefore the tested item is to be considered as non-irritant to the skin of rabbits.
Executive summary:

The primary irritation effect was assessed following the "Appraisal of the Safety of Chemicals in Foods, Drugs and Cosmetics" (1959) of the US Association of Food and Drug Officials (AFDO).

The result show no irritation on rabbit skin therefore the tested item is to be considered as non-irritant to skin.

Endpoint conclusion:
no adverse effect observed (not irritating)

Irritant / corrosive response data:
The primary irritation index is 3.2 which corresponds to a minimal irritating effect.
Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The primary irritation index is 3.2 which corresponds to a minimal irritating effect. Rinsing the eyes following instillation was of little
but assessable effect.
Executive summary:

The primary irritation effect was assested following the "Appraisal of the Safety of Chemicals in Foods, Drugs and Cosmetics" (1959) of the US Association of Food and Drug Officials (AFDO). The tested item contains a certain amount of a component which is classified as irritant to eyes.

The result show minimal irritation on rabbit eye following the indicated guideline but the tested item is to be considered as non-irritant to eye based on CLP criteria, table 3.2.2.7.1.

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

Respiratory irritation

Endpoint conclusion:
no study available

Additional information

Some studies are available both for skin and eye irritation based on the patch-test method described in "Appraisal of the safety of Chemicals in Food, Drugs and cosmetics of the US Association of Food and Drug Officials.

The results show:

- no eye irritation for observation at 1, 24, 48 and 72 h.

- no skin irritation for observation at 1, 24, 48 and 72 h.

The test item doesn't show any irritating effects and as a consequence it could be stated that is not corrosive.

Justification for classification or non-classification

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

No classification for eye irritation/corrosion is warranted under Regulation 1272/2008
