Endpoint summary

Description of key information
TODI was tested for skin and eye irritation/corrosion properties in studies with rabbits. TODI showed only very slight signs of irritation in eyes and on skin, which were completely reversible within the regular observation periods of the studies. It is concluded that TODI can be regarded as non-irritant to skin and eyes.

- Irritant / corrosive response data:
- 4-hour exposure period:
No erythema/eschar and oedema observed at observation times >= 24 h. All treated skin sites appeared normal at the 24-hour observation. Very slight erythema (individual score of 1) and very slight oedema (individual score of 1) were noted at two treated skin sites at the 1-hour observation. This effect was fully reversible within 24 hours. No corrosive effects were noted.
3-minute and 1-hour exposure period:
No evidence of skin irritation was noted during the study. No corrosive effects were noted. - Other effects:
- None
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test material, TODI, is considerd to be not irritating to rabbit skin according to the Draize classification scheme. No corrosive effects were noted.
- Executive summary:
A study was performed to assess the irritancy potential of the test material to the skin of the New Zealand White rabbit. The method used followed the recommendations of the OECD Guidelines for Testing of Chemicals No. 404.
A single 4 -hour, semi-occluded application of the test material to the intact skin of three rabbits produces very slight erythema and very slight oedema at two treated skin sites. All treated skin sites appreared normal at the 24 -, 48- and 72-hour observations. No corrosive effects were noted. 3 -minute and 1 -hour semi-occluded applications of the test material to the intact skin of one rabbit procued no corrosive effects. According to the results, the test material has no irritation and no corrosion potential.

- Executive summary:
A study was performed to assess the irritancy potential of the test material to the eye of the New Zealand White rabbit. The method used followed that described in the OECD Guidelines for Testing of Chemicals No. 405 "Acute Eye Irritation/ Corrosion" (adopted 24 February 1987) and Method B5 of Commission Directive 92/69/EEC.
The results may be used as a basis for classification and labelling under Annex VI of Council Directive 67/548/EEC relating to the classification, packaging and labelling of dangerous substances.
A single application of the test material to the non-irrigated eye of three rabbits produced minimal to moderate conjunctival irritation. Transient diffuse corneal opacity to one treated eye at the 24 -hour observation. Transient iridial inflammation was noted in two treated eyes. All eyes appeared normal at the 72 -hour observation.
The test material TODI, was not irritating to rabbits' eye.

Justification for classification or non-classification
Classification, Labeling, and Packaging Regulation (EC) No 1272/2008
The available data for skin irritation/corrosion and eye irritation/corrosion are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. Based on this data, the substance is neither considered to be classified for skin irritation/corrosion nor for eye irritation/corrosion under Regulation (EC) No 1272/2008, as amended for the seventeenth time in Regulation (EU) 2021/849.
