- STUDY DESING
The study was performed in a stepwise manner and was started by treatment of a single rabbit (sentinel). The two other animals were treated in a similar manner two weeks later, after considering the degree of eye irritation observed in the first animal.
TREATMENT
Each animal was treated by instillation of 0.1 mL of the test substance, in the conjunctival sac of one of the eyes after gently pulling the lower lid away from the eyeball. The lids were then gently held together for about one second to prevent loss of the test substance. The other eye remained untreated and served as the reference control.
Immediately after the 24-hour observation, a solution of 2% fluorescein (Merck, Darmstadt, Germany) in water (adjusted to pH 7.0) was instilled into both eyes of each animal to quantitatively determine corneal epithelial damage. Any bright green stained area, indicating epithelial damage, was estimated as a percentage of the total corneal area.
After the final observation, the animals were sacrificed by intra-venous injection of Euthasol® 20% (AST Farma BV, Oudewater, The Netherlands).

- Irritant / corrosive response data:
- Irritation:
Instillation of approximately 0.1 mL of the test substancee into one eye of each of three rabbits resulted in irritation of the conjunctivae, which consisted of redness, chemosis and discharge. The irritation had completely resolved within 48 hours in all animals.
No iridial irritation or corneal opacity were observed, and treatment of the eyes with 2% fluorescein 24 hours after test substance instillation revealed no corneal epithelial damage.
Corrosion:
There was no evidence of ocular corrosion. - Other effects:
- Coloration / Remnants:
No staining of (peri) ocular tissues by the test substance was observed and no test substance remnants were seen.
Toxicity / Mortality:
No symptoms of systemic toxicity were observed in the animals during the test period and no mortality occurred. - Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test substance does not have to be classified for eye irritation.
- Executive summary:
Acute eye irritation/corrosion study with the test substance in the rabbit was determined according to OECD 405 guideline and EU B5 Method with GLP.
Single samples of 0.1 mL of the test substance were instilled into one eye of each of three rabbits. Observations were made 1, 24, 48 and 72 hours after instillation.
Instillation of the test substance resulted in irritation of the conjunctivae, which consisted of redness, chemosis and discharge. The irritation had completely resolved within 48 hours in all animals.
Based on these results, Reaction products of n-octanol and acrylic acid, first distillation pitch does not have to be classified and has no obligatory labelling requirement for eye irritation according to the:
- Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations (2011),
- Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures.

Additional information
Key study:
Skin irritation/corrosion:
The possible corrosive and irritative potential of the test substance was carried out according to the OECD Guideline 404 (GLP study). 0.5 mL of the test substance was applicated onto clipped skin for 4 hours using a semi-occlusive dressing.
Irritation: The test substance caused a very slight erythema and very slight oedema in the treated skin areas. The skin irritation resolved within 24 hours after exposure in all animals.
Corrosion: There was no evidence of a corrosive effect on the skin.
Eye irritation:
The possible corrosive and irritative potential of the test substance was carried out according to the OECD Guideline 405 (GLP study). 0.1 mL of the test substance was instilled into one eye of each of three rabbits.
Irritation: The test substance caused a irritation of the conjunctivae, which consisted of redness, chemosis and discharge. The irritation had completely resolved within 48 hours after exposure in all animals.
Corrosion: There was no evidence of ocular corrosion.
Justification for selection of skin irritation / corrosion endpoint:
Only one study available. GLP compliant and of high quality (Klimisch 1).
Justification for selection of eye irritation endpoint:
Only one study available. GLP compliant and of high quality (Klimisch 1).
Justification for classification or non-classification
Based on these results Reaction products of n-octanol and acrylic acid, first distillation pitch does not have to be classified and has no obligatory labelling requirement for skin irritation according to the:
