- Executive summary:
Method:
Eye irritation potential was tested as described into the Code of Federal Regulations Title 16, Section 1500.42 1973. Test substance was instilled in one eye of 6 rabbits; the untreated eye served as control. No rinse of eye was done. Signs of irritation were scored at 1, 24, 48 and 72 h after start of exposure according to Draize criteria.
Results:
No signs of irritation as cornea opacity, iritis and conjunctivae chemosis were noted. Conjunctivae redness was noted in 2/6 rabbits; effects were slight and fully reversible within 72 h after start of exposure.

Additional information
Justification for classification or non-classification
- 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 exposure in a single animal but less than the criteria above.
- 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.
- Corneal opacity ≥ 1 and/or
- Iritis ≥ 1, and/or
- Conjunctival redness ≥ 2 and/or
- Conjunctival oedema (chemosis) ≥ 2
Skin Irritation
According to the CLP Regulation (EC n. 1272/2008), skin corrosion means the production of irreversible damage to the skin, and skin irritation means the production of reversible damage to the skin following the application of a test substance for up to 4 hours.
A substance has to be classified as category 1 (corrosive) if it 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 a 4 hour duration.
A substance has to be classified as category 2 (irritant) if shows:
In case 6 rabbits are used, a response above the threshold of 2.3 in 4 of 6 rabbits implies a classification in category 2.
As no irritation was seen, no classification applied.
Eye Irritation
According to the CLP Regulation (EC n. 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 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.
A substance has to be classified as category 1 (irreversible effects on the eye), if, when applied to the eye of an animal, a substance produces:
A substance has to be classified as category 2 (irritating to eye) if, when applied to the eye of an animal, a substance produces:
at least in 2 of 3 tested animals, a positive response of:
Calculated as the mean scores following grading at 24, 48 and 72 hours after installation of test material, and which fully reverses within an observation period of 21 days.
In case 6 rabbits are used, a response above the threshold in 4 of 6 rabbits implies a classification in category 2.
As irritation effects, in terms of conjunctiva redness were below the threshold of classification and recovered within 72 hours, no classification applied.
