SCORING SYSTEM:
Cornea opacity (op):
Degree of density (the most dense area is taken for reading)
0 = no ulceration or opacity
1 = Scattered or diffuse areas ot opacity (other than slight dulling of normal lustre), details of iris clearly visible;
2 = Easily discernible translucent area, details of iris slightly obscured
3 = Necreous area, no details of iris visible, size of pupil barely discernible
4 = Opaque cornea, iris not discernible through the opacity
Area of cornea involved (ar): (The assessment of these ocular reactions is performed independent of the quoted guidelines)
1 = 0 < =1/4
2 = >1/4<1/2
3 = 2<3/
4 = >3/4
Iris:
0 = Normal
1 = Markedly deepened rugae, congestion, swelling, moderate circumcorneal hyperaemia or injection, any of these observations or combination of any thereof, Iris still reacting to light (sluggish reaction is positive)
2 = No reaction to light, haemorrhage, gross destruction (any or all of these)
Conjunctivae redness (red):
(Refers to palpebral and bulbar conjunctivae, not to cornea and iris)
o = Blood vessels normal
1 = Some blood vessels definitely hyperaemic (injected)
2 = Diffuse, crimson colour, individual vessels not easily discernible
3 = Diffuse beefy red
Chemosis (sw):
Lids and/or nictitating membrane
0 = No swelling
1 = Any swelling above normal (includes nictitating membranes)
2 = Obvious swelling with partial eversion of lids
3 = Swelling with lids about half closed
4 = Swelling with lids more than half closed
Discharge (di): (The assessment of these ocular reactions is performed independent of the quoted guidelines)
0 = No discharge
1 = Any amount different from normal (does not include small amounts observed in inner canthus of normal animals)
2 = Discharge with moistening of the lids and hairs just adjacent to Iids
3 = Discharge with moistening of the lids and hairs, and considerable area around the eye

Clinical examinations and assessment of ocular findings
Slight corneal opacity (grade 1) was observed in all animals 24 hours after application and persisted in one animal up to 72 hours and in two animals up to day 7. Moderate iritis was seen in one animal 72 hours after application only. Slight to moderate conjunctival redness (grade 1 - 2), moderate to marked conjunctival chemosis (grade 2 - 3) and moderate discharge (grade 2) were observed in all animals 1 hour after application. Moderate or severe conjunctival redness (grade 2 or 3) was observed in all animals after 24 hours up to 72 hours and decreased to slight (grade 1) after 7 days. Moderate conjunctival chemosis (grade 2), noted in all animals 24 hours after application, persisted in one animal up to 72 hours and decreased to slight after 7 days, whereas in the other two animals chemosis decreased to slight after 48 up to 72 hours after application. Slight or moderate discharge (grade 1 or 2) was seen in all animals 24 hours after application. Slight discharge was noted in two animals from 48 hours up to 72 hours. In addition small retraction in the eyelid, suppuration, contracted pupil, discharge of blood, injected scleral vessels, circular or in a circumscribed area and marginal vascularization of the cornea in a circumscribed area were observed over the study period. The ocular reactions were reversible in all animals within 14 days after application. Mean scores calculated for each animal over 24, 48 and 72 hours were 1.0 for corneal opacity, 0.0, 0.3 and 0.0 for iris lesions, 2.0, 2.7 and 2.0 for redness of the conjunctiva and 1.3, 1.3 and 2.0 for chemosis.

Applicant's summary and conclusion
- Interpretation of results:
- Category 2 (irritating to eyes) based on GHS criteria
- Remarks:
- Migrated information
- Conclusions:
- GHS Classification: Causes severe eye irritation (Cat 2A)
- Executive summary:
In a guideline GLP eye irritation study, the substance 3,6,9,12-tetraoxahexadecan-1-ol was tested in rabbit eyes to assess the level of eye irritancy produced. The eyes were washed after 24 hours as permitted under the guideline. This can be considered more representative of the hazard in man as humans have a lachrymatory response to irritants (a response lacking in rabbits.) Under the conditions of the test, moderate eye irritation was observed, the most acute response being moderate to severe conjunctival erythema. All symptoms disappeared within 14 days. However, the corneal response and the amount of redness produced over the first threee days does meet the criteria for classification under the GHS as a severe eye irritant (Cat 2A).
