Applicant's summary and conclusion
- Interpretation of results:
- irritating
- Remarks:
- Migrated information Category 2 Criteria used for interpretation of results: other: CLP, EU GHS (Regulation (EC) No 1272/2008)
- Conclusions:
- The alterations induced by the test item were evaluated to the OECD 405 and Method B.5. In view of the results obtained the test item is considered to be non irritant to the eyes based on the criteria set out in Directive 2001/59/EC, Annex VI, and no risk phrase is required. According to CLP, EU GHS (Regulation (EC) No 1272/2008) the test item has to be classified as irritating to eyes (Category 2).
- Executive summary:
In a primary eye irritation study according to the OECD Guideline for the Testing of Chemicals 405 and Commission Directive 2004/73/EC Method B.5, 0.1 g of Phosphoric acid, mono- and di- C16-18 (even numbered) alkyl esters (100% a.i.) was instilled into the conjunctival sac of the right eye of three female, young adult New Zealand Whit rabbits for 1 hour. The remainder of the test item was removed with physiological saline before the first observation. Animals then were observed for 14 days.
The test item was administered initially to one animal. One hour after the application, diffuse crimson colouring (grade 2) was recorded in the conjunctiva, along with swelling with the lids more than half closed (grade 4). However, during the observations it was difficult to evaluate the hyperaemia due to the swelling of the conjunctiva. The test item was later applied to two more animals. Scattered or diffuse areas of opacity were recorded in the cornea, the details of the iris were clearly visible (grade 1) during the observation performed at one hour following the administration.
The mean values at 24, 48 and 72 hours following administration, for each type of lesion in the three treated animals were:
- Corneal opacity: 0.33
- Lesions in the iris: 0.00
- Hyperaemia: 2.22
- Edema: 0.89
In this study Phosphoric acid, mono- and di- C16-18 (even numbered) alkyl esters are irritating to the rabbit eye.
