Justification for type of information:

JUSTIFICATION FOR DATA WAIVING
In accordance with REACH Regulation (EC) No. 1907/2006 Annex VII, column 2 section 7.14 the study does not need to be conducted if the substance is marketed or used in a non-solid or granular form. The substance is a liquid. According to ECHA Guidance on Information Requirements and Chemical Safety Assessment (Chapter R.7a: Endpoint Specific Guidance, R.7.1.14, July 2017) the study does not need to be conducted.

Cross-reference

Reason / purpose for cross-reference:

other:

Reference

Weight of evidence: State of the substance at 20 °C and 101.3 kPa: clear colourless or colourless liquid, visual observation, 2020

Physical state at 20°C and 1013 hPa:

liquid

Form:

liquid

Colour:

colourless

During visual observation(s) of physical state and appearance by the testing laboratory the test material(s) were evaluated and determined to be a clear colourless or alternatively a colourless liquid. Both descriptions should be considered synonymous and an assertion as to the lack of turbidity or similar phenomena.
