Physical Description: Black solid
Storage Conditions: Kept in a controlled room temperature area
Constituent 1
Test system
- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied (volume or weight with unit): the test substance was tested neat via a gauze patch approximately 2cm2.
NEGATIVE CONTROL
- Amount(s) applied (volume or weight with unit): 750 µl of physiological saline per cornea
POSITIVE CONTROL
Amount(s) applied (volume or weight with unit): 750 µl per cornea
Concentration (if solution): 10% (w/v) Benzalkonium Chloride
- Duration of treatment / exposure:
- 10 minutes
- Observation period (in vivo):
- After exposure the cornea was thoroughly rinsed to remove the test substance and incubated for 2 hours
- Details on study design:
- TEST SITE
- Isolated bovine cornea
REMOVAL OF TEST SUBSTANCE
- Washing (if done): yes
- Time after start of exposure: 10 minutes
SCORING SYSTEM:
- After exposure the cornea was thoroughly rinsed to remove the test substance and incubated for 2 hours with fresh medium followed by opacity measurement and the permeability of the corneas was determined after a 90 minutes incubation period with sodium fluorescein.
- The mean opacity and mean permeability values (OD490) were used for each treatment group to calculate an in vitro score:
In vitro irritancy score (IVIS) = mean opacity value + (15 x mean OD490 value).
TOOL USED TO ASSESS SCORE:
- opacitymeter and microplate reader
DATA EVALUATION:
IVIS score:
= 3 No Category
> 3; = 55 No prediction can be made
>55 Category 1

Since EXP1313100 induced an IVIS > 3 = 55, no prediction on the classification can be made.
Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Since EXP1313100 induced an IVIS > 3 = 55, no prediction on the classification can be made.
- Executive summary:
The negative control responses of the opacity and permeability values were less than the upper limits of the laboratory historical rangeindicating that the negative control did not induce irritancy on the corneas.The mean in vitro irritancy score of the positive control (10% (w/v) Benzalkonium Chloride) was 126 and within the historical positive control data range. It was therefore concluded that the test conditions were adequate and that the test system functioned properly.
EXP1313100 induced ocular irritation through both endpoints, resulting in a mean in vitro irritancy score of 4.3 after 10 minutes of treatment.
