Administrative data

Endpoint:
eye irritation: in vivo
Type of information:
migrated information: read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
key study
Study period:
21 - 24 May 1991
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
GLP-guideline study, tested with the source substance fatty acids, C16-18, esters with pentaerythritol. According to the ECHA guidance document 'Practical guide 6: How to report read-across and categories' (ECHA, 2012), the reliability was changed from RL1 to RL2 to reflect the fact that this study was conducted on a read-across substance.

Irritant / corrosive response data:
One hour after instillation of the test substance, 2/3 animals had a discharge from the eye that persisted until the 24-hour reading time point in 1/3 rabbits. No conjunctional effect was observed after application of the test substance. The treated eyes were without any lesion on their cornea, and no effects on iris were observed at any reading time point during the test.
Other effects:
No further local or systemic adverse effects were observed.
