SCORING SYSTEM: according to OECD and Draize

Corneal Opacity (maximum possible: 4)
0 = no finding
1 = slight opacity
2 = well-defined opacity
3 = severe opacity
4 = very severe opacity

Involved corneal area
1 = > 0 - < ¼
2 = >= 1/4 - < ½
3 = >= ½ - < ¾
4 = >= 3/4

Iris (maximum possible: 2)
0 = no finding
1 = ciliary injection
2 = iritis

Conjunctival redness (maximum possible: 3)
0 = no finding
1 = slight redness
2 = well-defined redness
3 = severe redness

Conjunctival swelling (maximum possible: 4)
0 = no finding
1 = slight swelling
2 = well-defined swelling
3 = severe swelling
4 = very severe swelling

Secretion (maximum possible: 3)
0 = no finding
1 = slight increase
2 = well-defined increase
3 = severe increase

Calculation of the irritation index:
For each animal and each reading time point, the irritation index (I) was calculated according to following formula:
I = A + B + C
A = 5 x opacity x involved corneal area
B = 5 x iris
C = 2 x (conjunctival redness + swelling + secretion)

The primary irritation index (PI) was the sum of all irritation indices for all animals and all reading time points (24, 48 and 72 h), subdivided by 3 x the number of animals.

Additional information

Skin irritation:

A mild primary irritation was observed in one rabbit 1 hour after application, which was reversible within 24 hours (BASF AG, 1983). Although the test conditions were not in full accordance with OECD guideline 404, the results should be considered representative for the toxicological properties of 2-phenoxyethanol. 2-Phenoxyethanol was not an irritant to rabbit skin.

According to OECD 404, the skin irritation potential of 2-phenoxyethanol was determined (Sasol, 1983).The test substance was applied to the intact skin of rabbits for 4 hours under occlusive conditions. After removal of the test substance, no oedema, but very slight erythema were noted in 2 of 6 animals. All erythema were reversible within 48 hours. Under the test conditions, 2-Phenoxyethanol was not irritating to the skin.

Eye irritation: The single application of 0.1 mL unchanged test material in the eye of each of 3 rabbits clearly induced signs of irritation in all 3 animals; the signs were of maximal severity between 48 and 72 hours following application (BASF AG, 1983). Thereafter, a tendency to reversibility was observed and after 15 days, only one animal still displayed slight corneal opacity affecting less than ¼ of the corneal area of the treated eye. The test substance 2-phenoxyethanol is therefore considered an eye irritant.
