TOOL USED TO ASSESS SCORE: hand-slit lamp / fluorescein
The eyes were examined ophthalmoscopically with a slit lamp prior to the administration and 1, 24, 48, 72 hours and 4 and 5 days after the administration (animal nos. 1 and 3) and prior to the administration and 1, 24, 48, 72 hours and 4 to 8 days after the administration (animal no. 2). The eye reactions were observed and registered.
24 hours after administration, fluorescein was applied to the eyes before being examined to aid evaluation of the cornea for possible lesions. The fluorescein test was repeated on each day of observation.

Applicant's summary and conclusion
- Interpretation of results:
- Category 2 (irritating to eyes) based on GHS criteria
- Conclusions:
- According to the EC-Commission directive 67 /548/EEC and its subsequent amendments on the approximation of the laws, regulations and administrative provision relating to the classification, packaging and labelling of dangerous substances and the results obtained under the present test conditions, Fatty acids, C16-18 and C18-unsatd., compds. with triethanolamine is non- irritating to eyes, hence, no labelling is required.
According to the EC Regulation 1272/2008 and subsequent regulations, the test item required labelling with 'Warning' and 'H319: Causes serious eye irritation'. According to the classification of the Globally Harmonized Classification System (GHS) the test item should be assigned to the hazard category 2A and labelled with an exclamation mark, 'Warning' and 'Causes serious eye irritation'. - Executive summary:
Fatty acids, C16-18 and C18-unsatd., compds. with triethanolamine was tested in an acute eye irritation/corrosion test in rabbits according to EC method B.5. (Regulation (EC) No. 440/2008) and OECD guideline 405 (2002). A single instillation of 0.1 mLper animal into the conjunctival sac of the right eye of three rabbits caused the following changes:
Cornea opacity (grade 1) was observed in all animals 60 minutes to 4 days, in animal no. 2 until 7 days after instillation.Conjunctival redness (grade 1) was observed in all animals 60 minutes to 4 days, in animal no. 2 until 7 days after instillation.
Chemosis was observed in all animals:
- animal no. 1: 60 minutes (grade 2) and 24 to 72 hours (grade 1) after instillation;
- animal no. 2: 60 minutes (grade 2) and 24 hours to 4 days (grade 1) after instillation;
- animal no. 3: 60 minutes (grade 2) and 24 hours (grade 1) after instillation.
Mean 24 -72h scores for cornea, iris, conjuctiva and chemosis were 1/4, 0/2, 1/3 and 0.78/4 respectively.
The fluorescein tests performed on each day of observation revealed corneal staining (grade 1) in all animals up to 3/4 of the surface.
All findings observed had disappeared in animal nos. 1 and 3 until 5 days, in animals no. 2 until 8 days after instillation.
The irises were not affected by instillation of the test item.
There were no systemic intolerance reactions concerning behaviour, body weight and food consumption.
