Description of key information
The test material was subject to an Acute Dermal Irritation/Corrosion Test in the rabbit according to OECD TG 404. No skin reactions occured except a very slight erythema in 1/3 animals one hour after the end of exposure. Therefore, the test item has not to be classified for skin irritation according to Regulation (EC) No 1272/2008
The test material was subject to an Acute Eye Irritation/Corrosion Test in the rabbit according to OECD TG 405. No corneal effects were observed. Iridial responses were observed 24 h after application, fully reversible by 48 h after application. Conjunctival redness and Chemosis were observed in 3/3 animals up to 48 hours after application, fully reversible by 72 hours after application. As the mean values of the observed eye responses fall below the critical values for classification according to the criteria of Regulation (EC) No 1272/2008, the test material is not irritating to eyes and has not to be classified for eye irritation.

- Irritant / corrosive response data:
- Immediately after exposure erythema score 1 was noted in 4/6 intact skin sites and in 5/6 scarified skin sites. Erythema score 1 persisted in animal #2 until 48 h after exposure. Every other skin response was fully reversible by 48 h. Edema score 1 was noted immediately after exposure in 5/6 intact skin sites and in 4/6 scarified skin sites, fully reversible by 48 h after exposure.
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: other: CLP regulation
- Conclusions:
- According to the classification criteria of Regulation (EC) No 1272/2008 the test material is not irritating to skin under these test conditions. This conclusion is legitimate even though the applied testing regime differs from today's standard methods, as the observed skin responses were fully reversible in 5/6 animals 48 h after after exposure, which lasted 20 h longer than required by OECD TG 404. The test material contains relevant amounts of Permanent-Gelb G, which is identical to the submission substance. Therefore the test results are considered adequate to fulfil the endpoint requirements.
- Executive summary:
The test material was tested for skin irritancy according to FDA guidelines. Both intact and scarified skin sites of six rabbits were exposed to 0.5 ml test substance for 24 h under occlusive conditions and the skin responses were watched for 48 hours after end of exposure. Very slight erythema were noted in 5/6 animals immediately after end of exposure, fully reversible in 4/6 animals by 48 h after end of exposure. Very slight edema were noted in 5/6 animals immediately after end of exposure, fully reversible by 48 h after end of exposure. Therefore, the test item has not to be classified for skin irritation according to Regulation (EC) No. 1272/2008.

- Irritant / corrosive response data:
- No eye responses were noted in any animal at any time point.
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: other: CLP regulation
- Conclusions:
- The test material is not irritating to eyes under these test conditions. This conclusion is legitimate as three animals (group 1) were tested basically in accordance with today's standard methods regarding dosing, exposure duration, scoring system, reading time points and no eye responses were noted in any animal at any time point.
- Executive summary:
The test material was tested for eye irritancy according to a procedure described in the "Appraisal of the Safety of Chemicals in Foods, Drugs and Cosmetics" (1959) of the US Association of Food and Drug Officials (AFDO). 0.1 g neat test substance was applied to the conjunctival sac of one eye each of 6 animals (no washing in 3 animals, group 1, washing after 30 seconds in 3 animals, group 2) and eye responses were watched for seven days. No eye responses were noted in any animal at any time point. The test item is not irritating to eyes and has not to be classified as irritating to eyes according to the criteria of Regulation (EC) No 1272/2008.

- Endpoint:
- eye irritation: in vitro / ex vivo
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- an in vitro eye irritation study does not need to be conducted because adequate data from an in vivo eye irritation study are available
