- Executive summary:
Method
The study was performed to assess the irritation of the test material to the eye of the New Zealand White rabbit. The method followed is the Guidelines of the United States Environmental Protection Agency (EPA) Paragraph 163.81-5 "Primary eye irritation study", Federal Register, Vol. 43 No. 163 August 22, 1978.
The test material in an amount of 0.1 ml was inserted in the conjunctival sac of the left eye of the rabbits and the lids were gently closed for 15 seconds. The right eye was not treated and served as an untreated control. In 3 of the 6 rabbits approximately 30 seconds after the treatment the treated eye was flushed with 10 ml of sterile physiological saline. The eye irritation was assessed with a slit-lamp at 24, 48, 72 hours and 4 and 7 days after treatment and was scored for each individual rabbit.
Results
The test material produced a minimal cornea irritation on 3/6 animals and minimal conjunctival irritation (redness) on 5/6 animals. . All treated eyes appeared normal at the 72-hour observation.
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 animals.
Therefore the substance does not meet the criteria to be classified as eye irritating.
In conclusion, the test item can be not classified as irritating, according to the CLP Regulation (EC 1272/2008).

Additional information
Skin irritation:
One study (Huntsman, 1985) has been chosen as key study for the skin irritation endpoint.
The test follows the Guidelines of the United States Environmental Pr otection Agency (EPA), Paragraph 163.81-5 "Primary dermal irritaion study", Federal Register, Vol 43 No. 163, August 22, 1978. and it was performed on Acid Violet 054.
0.5 ml of test material were applied to intact and abraded skin of rabbits and removed after 24 hours. Observations were made for 7 days.
Since no animals were observed an average of erythema and eschar or edema more than 2, the tested substance is classified as not irritant for skin.
Another study (Huntsman, 1975) is available for Acid Violet 054 and was used as supporting.
The test follows the guideline "Hazardous Substances Regulations" under the U.S. Federal Hazardous Substances Labelling Act Sect. 191.11 (February 1965) and it was performed on Acid Violet 054.
10g of the test compound was mixed with 10ml of water to make a solution of 15ml, 0.75ml of which was applied to each test site on a 2.5 cm square gauze pad.
After 24 hours the dressing was removed and the intact and abraded application sites were assessed for oedema and erythema. A further assessment was made at 72 hours.
Since no animals were observed an average of erythema and eschar or edema more than 2, the sample is classified as not irritant for skin.
A summary (Dystar, 1977) is also available for Acid Violet 054, confirming that Acid Violet 054 is not irritant for skin.
Eye irritation:
One study (Huntsman, 1985) has been chosen as key study for the eye irritation endpoint.
The test follows the Guidelines of the United States Environmental Protection Agency (EPA) Paragraph 163.81-5 "Primary eye irritation study", Federal Register, Vol. 43 No. 163 August 22, 1978 and it was performed on Acid Violet 054.
The test material in an amount of 0.1 ml was inserted in the conjunctival sac of the left eye of the rabbits and the lids were gently closed for 15 seconds. The right eye was not treated and served as an untreated control. In 3 of the 6 rabbits approximately 30 seconds after the treatment the treated eye was flushed with 10 ml of sterile physiological saline. The eye irritation was assessed with a slit-lamp at 24, 48, 72 hours and 4 and 7 days after treatment and was scored for each individual rabbit.
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 animals.
Therefore the substance does not meet the criteria to be classified as eye irritant.
Another study (Huntsman, 1975) is available for Acid Violet 054 and was used as supporting.
The test follows the guideline U.S.A. Federal Hazardous Substances Labelling Act Sect. 191.12 (February 1965) and it was performed on Acid Violet 054.
100mg of the test compound were instilled into the conjunctival sac of the left eye. The eyelids were then held closed for 1 second. The right eye served as a control. After 30 seconds the compound was, as far as possible, flushed out of the eyes of three of the rabbits with warm water for 1 minute.
The rabbits were examined 1, 24, 48 and 72 hours after application of the test compound and for any further period that was considered necessary.
The test material produced a cornea irritation on 3/6 animals, conjunctival irritation (redness) on all the animals and minimal chemosis irritation on all animals. Even if there is a minimal irritation for all the aspects investigated , all treated eyes appeared normal at the 72-hour observation.
The mean values from gradings at 24, 48 and 72 hours were lower than 1 for corneal opacity, equal to 2 for conjunctival redness and lower than 2 for oedema, in at least 2/3 animals.
Therefore the substance does not meet the criteria to be classified as eye irritant.
A summary (Dystar, 1977) is also available for Acid Violet 054, confirming that acid Violet 054 is not irritant for eyes.
Justification for selection of skin irritation / corrosion
endpoint:
The study is well described and assesses the end point completely
Justification for selection of eye irritation endpoint:
The study is well described and assesses the end point completely
Justification for classification or non-classification
According to the CLP Regulation (EC 1272/2008), skin Irritation means the production of reversible damage to the skin following the application of a test substance for up to 4 hours.
In the key study, the mean values from gradings at 24, 48 and 72 hours after patch removal were lower than 2.3 in at least 2 of 3 animals for both erythema/eschar and oedema reactions.
According to the CLP Regulation (EC 1272/2008) substances that have the potential to induce reversible eye irritation are classified in Category 2 (irritating to eyes) if, when applied to the eye of an animal, a substance produces at least in 2 of 3 tested animals, a positive response of corneal opacity ≥ 1 and/or iritis ≥ 1, and/or conjunctival redness ≥ 2 and/or conjunctival oedema (chemosis) ≥ 2, calculated as the mean scores following grading at 24, 48 and 72 hours after installation of the test material, and which fully reverses within an observation period of 21 days.
The mean values from gradings at 24, 48 and 72 hours recorded in the key study were lower than 1 for corneal opacity, lower than 1 for iritis, lower than 2 for both conjunctival redness and oedema, in all animals in the key study.
In conclusion, the substance is not classified for the eye/skin irritation, according to the CLP Regulation (EC 1272/2008).
