IN-LIFE DATES: From: 06 July 2016 to 21 July 2016
Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- other: One eye of each animal remained untreated and served as the reference control.
- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied: average 42.6 mg (range: 42.4 mg – 42.9 mg) (a volume of approximately 0.1 mL) - Duration of treatment / exposure:
- Single instillation on day 1
- Observation period (in vivo):
- 72 hours after instillation of the test item
- Number of animals or in vitro replicates:
- 3 males
- Details on study design:
- STUDY DESIGN
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 12 days later, after considering the degree of eye irritation observed in the first animal.
TREATMENT
Test item was installed in the conjunctival sac of one of the eyes.
REMOVAL OF TEST SUBSTANCE
-Washing (if done): Yes
Immediately after the 1 hour observation, the treated eye of two of the animals, were rinsed with approximately 30 mL tepid tap water, using a velocity of flow which did not affect the eye, to remove any visible residual test item. For reference control the other eye was also rinsed.
OBSERVATIONS
- Mortality/Viability: Twice daily.
- Toxicity: At least once daily.
- Body Weight: Day of treatment (prior to instillation) and after the final observation.
- Necropsy: No necropsy was performed. After the final observation, the first animal was sacrificed. The other two animals were removed from the study alive.
- Irritation: The eyes of each animal were examined approximately 1, 24, 48 and 72 hours after instillation of the test item.
The irritation scores and a description of all other (local) effects were recorded. The irritation was assessed according to OECD 405.
Where standard lighting was considered inadequate for observing minor effects, eye examinations were performed using an ophthalmic examination lamp.

Instillation of the test item into one eye of each of three rabbits resulted in slight irritation of the conjunctivae, which consisted of redness (1 animal, score 1), chemosis (2 animals, score 1) and/or discharge (2 animals, score 1) at 1 hour after instillation only. Two animals showed slight irritation of the conjunctivae, which consisted of redness (score 1) at 1 hour and 24 hours after installation. The irritation had completely resolved within 24 hours in one animal and within 48 hours in the other two animals.
No iridial irritation or corneal opacity were observed, and treatment of the eyes with 2% fluorescein 24 hours after test item instillation revealed no corneal epithelial damage. - Other effects:
- Remnants of the test item were present in the eye of two animals on day 1.
No signs of systemic toxicity were observed in the animals during the test period and no mortality occurred.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In an eye irritation study with rabbits, performed according to OECD 405/EC test guidelines, limited irritation was observed.
- Executive summary:
An acute eye irritation study in the rabbit was performed with Resin acids and Rosin acids, hydrogenated, zinc salts according to OECD 405/EC guidelines and in accordance with GLP principles. Single samples of approximately 42.6 mg of Resin acids and Rosin acids, hydrogenated, zinc salts (a volume of approximately 0.1 mL) were instilled into one eye of each of three rabbits. Observations were made 1, 24, 48 and 72 hours after instillation. Slight irritation of the conjunctivae, which consisted of redness (all animals, score 1), chemosis (2/3 animals, score 1) and/or discharge (2/3 animals, score 1) were observed after installation. The irritation had completely resolved within 24 hours in one animal and within 48 hours in the other two animals. Remnants of the test item were present in the eye of two animals on day 1.
Based on these results, Resin acids and Rosin acids, hydrogenated, zinc salts do not have to be classified and have no obligatory labelling requirement for eye irritation according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations (2015) (including all amendments) and EC criteria for classification and labelling requirements for dangerous items and preparations (Council Directive 67/548/EEC) (including all amendments).
