Additional information

There is one study available for each of skin and eye irritation.Tetrapropyl orthosilicate was not irritating to skin or eyes in reliable studies.


Justification for selection of skin irritation / corrosion endpoint:
The selected study is the only skin irritation study available for the registered substance. It was conducted in accordance with an appropriate OECD test guideline and in compliance with GLP.

Justification for selection of eye irritation endpoint:
The selected study is the only eye irritation study available for the registered substance. It was conducted in accordance with an appropriate OECD test guideline and in compliance with GLP.

Justification for classification or non-classification

Based on the available data tetrapropyl orthosilicate is not classified for skin or eye irritation under Regulation (EC) No1272/2008.
