Pigment Yellow 214

Endpoint summary

Description of key information

The eye irritating potential of the test item was assessed according to OECD TG 405. Three rabbits were exposed to 0.1 mg test item. The mean score was calculated across three scoring times (24, 48 and 72 hours after instillation) for each animal for corneal opacity, iris, redness and chemosis of the conjunctivae, separately. The individual mean scores for corneal opacity and iris were 0.00 for all three animals.

The individual mean scores for the conjunctivae were 0.00, 0.00 and 0.33 for reddening and 0.00, 0.00 and 0.67 for chemosis for all animals, respectively.One hour after instillation all treated animals showed slight conjunctival redness (score 1) and one animal showed also slight chemosis (score 1).All effects were fully reversible within 72 h.

- Time after start of exposure: 4 h, at the end of exposure time

OBSERVATION TIME POINTS
1, 24, 48 and 72 h after removal of the test substance

SCORING SYSTEM:
- Method of calculation: The skin reactionwas assessed according to the numerical scoring system listed in the EEC Commission Directive 92/69/EEc, July 31, 1992.
The primary irritation score was calculated by totalling the individual cummulative scores at 24, 48 and 72 h and then dividing by the number of data points.

Irritant / corrosive response data:

No corrosive or irriating effects observed.

No clinical signs of systemic toxicity were observed in the animals during the test and observation period, and no mortality ocurred.

Yellow stainig of the treated skin was observed.

Interpretation of results:

GHS criteria not met

Conclusions:

The test item did not reveal any irritation potential on the skin of rabbits, tested in this study according to OECD test guideline no. 404 and GLP conditions.

Executive summary:

The skin irritating potential of the test item was assessed according to OECD TG 404. Three rabbits (1 male and 2 females) were exposed to 0.5 mg test item under semi-occlusive conditions for 4 hours. Yellow staining produced by the colour of the test item on the treated skin was observed in all animals at the 1-hour reading and persisted up to the 48- or 72-hour reading. The test item did not elicit any skin reactions at the application site of any animal at any of the observation times (all scores 0). The individual mean score for erythema/eschar and oedema for each of the three animals was therefore 0.
