Method:
The eye irritation was determined in an irritation test on rabbits according to OECD Guideline 405 and EU Method B.5.
Observation:
The mortality was evaluated daily while the body weights was assessed at day 1 and at termination of the test on a Mettler PK 16 balance. The eyes of each animal were examined 1, 24, 48 and 72 hours after administration. The corrosive properties of the test article and the colour of the treated eye were described and recorded.
Result:
Non irritant

Additional information
No experimental studies are available for the substance in itself.
Nevertheless studies were conducted on analogue substances. Further information are reported in the Read Across justification attached to section 13.
Skin Irritation
Similar Substance 01 was evaluated for its skin irritation potential according to the "Appraisal of the Safety of Chemicals in Foods, Drugs and Cosmetics" (1959) of the US Association of Food and Drug Officials (AFDO)", similar to the OECD Guideline 404. No information are available about the composition of the batch tested.
0.5 g of the test substance was applied on the skin of six rabbits using gauze patches, then covered by impermeable material. After 24 hours the gauzes were removed and the skin observed for 8 days.
The mean score of observed values of irritation/corrosion, calculated for each rabbit, after 24, 48, 72 hours, were always under the limit for irritation potential set out in the OECD guideline, therefore the substance is considered as non irritant.
To support this result a second study conducted on the Similar Substance 02 was taken in account.
The skin irritation was determined in an irritation test on rabbits according to Appraisal of the Safety of Chemicals in Foods, Drugs and Cosmetics (1959), the US Association of Food and Drug Officials (AFDO), similar to OECD guideline 404. The test substance resulted to be not irritant.
Eye Irritation
Analogue substance 01 was evaluated for its eye irritation potential according to the OECD Guideline 405 and EU Method B.5.
The test article (0.1 g per animal) was placed in the conjunctival sac of the left eye of each animal after gently pulling the lower lid away from eyeball. The lids were then gently held together for about one second to prevent loss of the test article. The right eye remained untreated and served as the reference control. The eyes of the animals were observed for 72 hours.
The mean score of observed values of irritation/corrosion, calculated for each rabbit, after 24, 48, 72 hours, were always under the limit for irritation potential set out in the OECD guideline, therefore the test item does not show any eye irritation potential.
Justification for classification or non-classification
SKIN IRRITATION/CORROSION
A corrosive substance is a substance that produces destruction of skin tissue, namely, visible necrosis through the epidermis and into the dermis, in at least 1 tested animal after exposure up to 4 hour duration.
Three sub-categories are provided within the Corrosive category 1:
- Subcategory 1A where responses are noted following up to 3 minutes exposure and up to 1 hour observation;
- Subcategory 1B where responses are described following exposure between 3 minutes and 1 hour and observations up to 14 days;
- Subcategory 1C where responses occur after exposures between 1 hour and 4 hours and observations up to 14 days;
To classify a substance as irritant, the major criterion is that at least 2 of 3 tested animals have a mean score of ≥ 2.3 - ≤ 4.0.
Category 2:
- Mean value of ≥ 2.3 - ≤ 4.0 for erythema/eschar or for oedema in at least 2 of 3 tested animals from gradings at 24, 48 and 72 hours after patch removal or, if reactions are delayed, from grades on 3 consecutive days after the onset of skin reactions; or
- Inflammation that persists to the end of the observation period normally 14 days in at least 2 animals, particularly taking into account alopecia (limited area), hyperkeratosis, hyperplasia, and scaling; or
- In some cases where there is pronounced variability of response among animals, with very definite positive effects related to chemical eposure in a single animal but less than the criteria above.
The substance is not classified as skin irritant because in the performed test it doesn't meet the classification criteria of the CLP regulation n. 1272/2008.
EYE IRRITATION
Serious eye damage means the production of tissue damage in the eye, or serious physical decay of vision, following application of a test substance to the anterior surface of the eye, which is not fully reversible within 21 days of application.
Eye irritation means the production of changes in the eye following the application of test substance to the anterior surface of the eye, which are fully reversible within 21 days of application.
Irreversible effects on the eye (Category 1):
If, when applied to the eye of an animal, a substance produces:
- At least in one animal effects on the cornea, iris or conjunctiva that are not expected to reverse or have not fully reversed within an observation period of normally 21 days; and/ or
- At least in 2 of 3 tested animals, a positive response of corneal opacity ≥ 3 and/or iritis > 1.5 calculated as the mean scores following grading at 24, 48 and 72 hours after installation of the test material.
These observations include animals with grade 4 cornea lesions and other severe reactions (e.g., destruction of cornea) observed at any time during the test, as well as persistent corneal opacity, discoloration of the cornea by a dye substance, adhesion, pannus, and interference with the function of the iris or other effects that impair sight. In this context, persistent lesions are considered those which are not fully reversible within an observation period of normally 21 days. Substances are also classified in Category 1 if they fulfil the criteria of corneal opacity ≥ 3 or iritis > 1.5 detected in a Draize eye test with rabbits, recognising that such severe lesions usually do not reverse within a 21-day observation period.
Irritating to eyes (Category 2)
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 substance is not classified as eye irritant because in the performed test it doesn't meet the classification criteria of the CLP regulation n. 1272/2008.
