The positive control, 100 % ethanol, was categorized and received and the negative control, Minimal Essential Material (MEM), was used as a 10% solution in 0.9% saline.
Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (irreversible effects on the eye) based on GHS criteria
- Remarks:
- Severe/corrosive eye irritant
- Conclusions:
- The material was considered a severe/corrosive eye irritant. The material was classified in Category 1.
- Executive summary:
To determine the potential for ocular irritation using an alternative to the Draize methodology, a study based on the methodology described in the current OECD Guideline for the Testing of Chemicals No. 437 was conducted. Three bovine corneas per group were dosed with 0.75 ml of Reaction Mass of 4- sulphophthalic acid (CAS 89-08-7) and 3-sulphophthalic acid (CAS 67892-43-7), 3:1 ratio, Minimal Essential Media (MEM, negative control), or 100% ethanol (positive control). Following a 10-minute exposure for each group of dosed corneas, opacity measurements and sodium fluorescein permeability were determined. The MEM solution is then removed from the anterior chamber and replaced with 1.0 ml of 0.4% sodium fluorescein solution. After 90 min the fluid from the posterior chamber is removed and the amount of dye that passed through the cornea is measured as the optical density at 490 nm by a plate reader. For the test substance, the in vitro irritancy score (IVIS) is 162.35, corneal opacity score is 158.00, and the permeability score is 0.290. Based on an IVIS of greater than 55, and as defined in OECD Guideline No. 437, the reaction mass of sulphophthalic acid was determined to be GHS Category 1 and was considered a severe/corrosive eye irritant.
