Executive summary:

A study was performed to assess the irritation of the test material to the skin of the New Zealand White rabbit (SPL Standard Test Method 540.05). The method followed OECD Guidelines for Testing of Chemicals (1992) No. 404 "Acute Dermal lrritation/Corrosion" and Method B4 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC).

A single, 4-hour semi-occluded application (500 mg) of the test material was administered to the intact skin of three rabbits. Skin reactions were recorded 1, 24, 48 and 72 hours after administration.

Primary Initation Index resulted to be 0. Yellow staining of the test site was recorded at the 1 and 24-hour observations which did not affect the evaluation of skin respotrses.

Therefore, the test material did not meet the criteria for classification as initant or corrosive according to EU labelling regulations Commission Directive 93/2l/EEC. No symbol and risk phrase are required.

Conclusion

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, thus the test item does not meet the criteria to be classified as irritating, according to the CLP Regulation (EC) No 1272/2008.

Executive summary:

A study was performed to assess the irritation of the test material to the eye of the New Zealand White rabbit (SPL Standard Test Method 560.06). The method followed OECD Guidelines for Testing of Chemicals (1987) No. 405 "Acute Eye Irritation/Corrosion" and Method B5 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC). A single application of 0.1 ml (67.3 mg) of the test material was administered to the non irrigated eye of three rabbits. Ocular reactions were record at 1, 24, 48 and 72 hours after administration.

The Maximum Group Mean Score was 4.1 and the related classification was as mild irritant (class 4 on a 1 -8 SCALE).

Any way, the  test material did not meet the criteria for classification as irritant or conosive according to EU labelling regulations Commission Directive 93/21/EEC. No symbol and risk phrase are required.

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 oedema, in all of the three tested animals.

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

A study was performed to assess the irritation of the test material to the skin of the New Zealand White rabbit (SPL Standard Test Method 540.05). The method followed OECD Guidelines No. 404 and the EU Method B4. A single, 4-hour semi-occluded application (500 mg) of the test material was administered to the intact skin of three rabbits. Skin reactions were recorded 1, 24, 48 and 72 hours after administration. Primary Initation Index resulted to be 0. Yellow staining of the test site was recorded at the 1 and 24-hour observations which did not affect the evaluation of skin respotrses.

EYE IRRITATION

A study was performed to assess the irritation of the test material to the eye of the New Zealand White rabbit (SPL Standard Test Method 560.06). The method followed OECD Guidelines 405 and the EU Method B.5. A single application of 0.1 ml (67.3 mg) of the test material was administered to the non irrigated eye of three rabbits. Ocular reactions were record at 1, 24, 48 and 72 hours after administration. The Maximum Group Mean Score was 4.1 and the related classification was as mild irritant (class 4 on a 1 -8 SCALE). Any way, the  test material did not meet the criteria for classification as irritant or conosive according to EU labelling regulations Commission Directive 93/21/EEC. No symbol and risk phrase are required.

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.

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, thus the test item does not meet the criteria to be classified as irritating, according to the CLP Regulation (EC) No 1272/2008.

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 oedema, in all of the three tested animals. All the reactions resulted to be fully reversible withing 72 hours. Therefore, the substance does not meet the criteria to be classified as eye irritating, according to the CLP Regulation (EC) No 1272/2008.
