Endpoint:
surface tension
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because surface activity is not a desired property of the material

Description of key information

Surface activity is not a desired property of the material.

Key value for chemical safety assessment

Additional information

A key study reporting a reliable value for TDI-Urone surface tension is not available. However, in accordance with Column 2 adaptation statement of REACH Annex VII, information requirement section 7.6, a key study does not need to be conducted as surface activity is not a desired property of the material.

The online database ChemSpider (http://www.chemspider.com/) reports a calculated value for TDI-Urone surface tension of 49.98 dyne/cm, which is extremely low compared to e.g. water.
