- Executive summary:
The potential of the test material to cause irritation to the skin was determined in accordance with the standardised guidelines OECD 404, EU Method B.4, OPPTS 870.2500 and JMAFF, under GLP conditions.
During the study 0.5 mL of test material was applied for 4 hours to the intact skin of three rabbits, using a patch of 2.5 cm x 2.5 cm, covered with semi-occlusive dressing. After removal of the patch the application area was washed. The cutaneous reactions were assessed immediately after removal of the patch, approximately 1, 24, 48, 72 hours and 7 days after removal of the patch.
Slight or moderate erythema was observed in the animals during the course of the study. In one animal erythema was partly extended beyond the area of exposure. The cutaneous reactions were reversible in all animals within 7 days after removal of the patch at latest. The average score (24 to 72 hours) for irritation was calculated to be 0 .4 for erythema and 0.0 for oedema.
Under the conditions of this study, the test material was not considered to be irritating to the skin.

SCORING SYSTEM:
- Readings were made at approx. 1, 24, 48 and 72 h after application.
- Assessment of ocular reactions:
Cornea opacity (op):
Degree of density (the most dense area is taken for reading)
0 = No ulceration or opacity
1 = Scattered or diffuse areas of opacity (other than slight dulling of normal lustre), details of iris clearly visible
2 = Easily discernible translucent area, details of iris slightly obscured
3 = Nacreous 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):
1 = > 0 ≤ ¼
2 = > ¼ < ½
3 = > ½ < ¾
4 = > ¾
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)
0 = 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):
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 lids
3 = Discharge with moistening of the lids and hairs, and considerable area around the eye
EVALUATION OF RESULTS
- For evaluation, the calculation of the mean values of corneal opacity, iris, conjunctival redness and chemosis for readings 24, 48 and 72 hours were quoted. Additionally, the reversibility of the observed findings was taken into account.
TOOL USED TO ASSESS SCORE: Daylight tubes "Lumilux" were used for illumination when reading the eye.

About 24 hours after application the eye was rinsed with tap water. The ocular reactions were assessed approximately 1, 24, 48 and 72 hours after application.
Slight or moderate conjunctival redness, slight conjunctival chemosis and slight discharge were observed in the animals up to 24 hours after application at latest.

Additional information
Eye Irritation (Remmele, 2005)
The potential of the test material to cause irritation to the eye was investigated in accordance with the standardised guidelines OECD 405, EU Method B5, OPPTS 870.2400 and JMAFF, under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
During the study, 0.1 mL of test material was applied to one eye of three White New Zealand rabbits (stepwise procedure starting with one animal and supplementing two additional animals). About 24 hours after application the eye was rinsed with tap water. The ocular reactions were assessed approximately 1, 24, 48 and 72 hours after application.
Slight or moderate conjunctival redness, slight conjunctival chemosis and slight discharge were observed in the animals up to 24 hours after application at latest. In addition, injected scleral vessels in a circumscribed area or circular were noted in all animals 1 hour after application. The average score (24 to 72 hours) for irritation was calculated to be 0.0 for corneal opacity and iris, 0 .1 for conjunctival redness and 0.0 for chemosis.
Under the conditions of this study, the test material was concluded to be not irritating to eyes.
Skin (Remmele, 2005)
The potential of the test material to cause irritation to the skin was determined in accordance with the standardised guidelines OECD 404, EU Method B.4, OPPTS 870.2500 and JMAFF, under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
During the study 0.5 mL of test material was applied for 4 hours to the intact skin of three rabbits, using a patch of 2.5 cm x 2.5 cm, covered with semi-occlusive dressing. After removal of the patch the application area was washed. The cutaneous reactions were assessed immediately after removal of the patch, approximately 1, 24, 48, 72 hours and 7 days after removal of the patch.
Slight or moderate erythema was observed in the animals during the course of the study. In one animal erythema was partly extended beyond the area of exposure. The cutaneous reactions were reversible in all animals within 7 days after removal of the patch at latest. The average score (24 to 72 hours) for irritation was calculated to be 0 .4 for erythema and 0.0 for oedema.
Under the conditions of this study, the test material was not considered to be irritating to the skin.
