- Area of exposure: on the day of treatment test item was setted on a surgical garuze patch (ca.2.5 cm x 2.5 cm). The gauze patch was applied to approximately 6 cm2 of the intact skin of the clipped area.
- Type of wrap if used: the patch was covered with a semi-occlusive dressing. The dressing was wrapped around the abdomen and anchored with tape.
REMOVAL OF TEST SUBSTANCE
- Washing: the dressing was removed and the skin was flushed with lukewarm tap water to clean the application site so that any reactions (erythema) were clearly visible at that time.
- Time after start of exposure: 4 hours.
OBSERVATIONS
- Viability/Ivlortality: daily from delivery of the animals to the termination of test.
- Clinical signs: daily from delivery of the animals to the termination of test.
- Body weights: at start of acclimatization, on the day of application and at termination of observation.
OBSERVATION TIME POINTS
The skin reaction was assessed at approximately 1, 24, 48 and 72 hours after the removal of the dressing, gauze patch and test article.
SCORING SYSTEM:
The skin reaction was assessed according to the numerical scoring system listed in the EEC Commission Directive 92/69/EEC, July 31, 1992.
If evident, corrosive or staining properties of the test article were described and recorded.

- Time point:
- 24/48/72 h
- Score:
- < 2.3
- Remarks on result:
- no indication of irritation
- Irritant / corrosive response data:
- Application of the test article to healthy intact rabbit skin resulted in a primary irritation score of 0.00.
Local signs (mean values from 24 to 72 hours) consisted of grade 0.00 erythema and grade 0.00 oedema. No signs of irritation were observed.
Light red staining by the test article of the treated skin was observed.
No irreversible alterations of the treated skin were observed nor were corrosive effects evident on the skin. - Other effects:
- VIABILITY/MORTALITY AND CLINICAL SIGNS
No clinical signs of systemic toxicity were observed in the animals during the test and observation period, and no mortality occurred.
BODY WEIGHTS
The body weight of all rabbits were considered to be within the normal range of variability. - Interpretation of results:
- other: not classified, according to the CLP Regulation (EC) No 1272/2008
- Conclusions:
- Not skin irritating
- Executive summary:
The primary skin irritation potential of the test article was investigated by topical application of 0.5 g to 6 cm2 intact dorsal skin of each of three young adult New Zealand White rabbits. The duration of treatment was four hours. The scoring of skin reactions was performed 1, 24, 48 and 72 hours after removal of the dressing. The scores of each animal at the following reading times (24, 48, 72 hours) were used in calculating the respective mean values for each type of lesion.
The primary irritation score was calculated by totaling the individual cumulative scores at 24, 48 and 72 hours and then dividing by the number of data points. The primary irritation score was 0.00 (max. 8.0).
Local signs (mean values from 24 to 72 hours) consisted of grade 0.00 erythema and grade 0.00 oedema. The test article caused light red staining of the treated skin. No corrosive effects were noted on the treated skin of any animal at any measuring interval.
Conclusion
None of the animals showed any observable response to treatment throughout the 72 hours observation period, thus it can be concluded that the test item does not meet the criteria to be classified as irritating, according to the CLP Regulation (EC) No 1272/2008.

- other: not classified, according to the CLP Regulation (EC) No 1272/2008
- Conclusions:
- Non irritating
- Executive summary:
The primary irritation potential of test item was investigated by instillation of 0.1 g into one eye of each of three young adult New Zealand White rabbits.

The primary irritation score was 0.56 (max. 13). Hyperemic conjunctival blood vessels were noted in all animals at the 24-hour examination and persisted through 72 hours in one animal only. This latter was observed with a slight swelling of the conjunctivae at the 1-hour examination.
Reddish-brown rernnants in eye or conjunctival sac and around eye and/or on lids were observed until the 72-hour reading. All eye reactions were reversible within 7 days after treatment. No corrosion was observed at any of the measuring intervals.
Conclusion
The mean values from gradings at 24, 48 and 72 hours were lower than 1 for corneal opacity, lower than 1 for iritis, lower than 2 for both conjunctival redness and chemosis, in all the tested animals. All the reactions recorded were reversible within 7 days. Therefore, the substance does not meet the criteria to be classified as eye irritating, according to the CLP Regulation (EC) No 1272/2008.

Additional information
SKIN IRRITATION
There are no information about the skin irritation potential of Reactive Red 147, thus the available information on the structural analogous Similar Substance 01 have been taken into consideration; the read across approach can be considered as appropriate and suitable to assess the property under investigation (details about the approach are reported into the IUCLID section 13).
The primary skin irritation potential of the Similar Substance 01 was investigated by topical application of 0.5 g to 6 cm2 intact dorsal skin of each of three young adult rabbits. The duration of treatment was four hours. The primary irritation score was calculated by totaling the individual cumulative scores at 24, 48 and 72 hours and then dividing by the number of data points. The primary irritation score was 0.00 (max. 8.0). Local signs (mean values from 24 to 72 hours) consisted of grade 0.00 erythema and grade 0.00 oedema. The test article caused light red staining of the treated skin. No corrosive effects were noted on the treated skin of any animal at any measuring interval.

The primary irritation score was calculated by totaling the individual cumulative scores at 24, 48 and 72 hours and then dividing the resulting total by the number of data points. The primary irritation score was 0.56 (max. 13). Hyperemic conjunctival blood vessels were noted in all animals at the 24-hour examination and persisted through 72 hours in one animal only. This latter was observed with a slight swelling of the conjunctivae at the 1-hour examination. Reddish-brown rernnants in eye or conjunctival sac and around eye and/or on lids were observed until the 72-hour reading. All eye reactions were reversible within 7 days after treatment. No corrosion was observed at any of the measuring intervals.
Justification for classification or non-classification
According to the CLP Regulation (EC) No 1272/2008, 3.2 Skin corrosion/irritation section, skin irritation means the production of reversible damage to the skin following the application of a test substance for up to 4 hours.
The mean values from gradings at 24, 48 and 72 hours after patch removal were lower than 2.3 in all animals for both erythema/eschar and oedema reactions.
According to the CLP Regulation (EC) No 1272/2008, serious eye damage means the production of tissue damage in the eye, or serious physical decay of vision, following application of a test substance, which is not fully reversible within 21 days of application.
The mean values from gradings at 24, 48 and 72 hours were lower than 1 for corneal opacity, lower than 1 for iritis, lower than 2 for both conjunctival redness and chemosis, in all the tested animals. All the reactions recorded were reversible within 7 days.
In conclusion, the substance does not meet the criteria to be classified for the eye/skin irritation, according to the CLP Regulation (EC) No 1272/2008.
