Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is a solid

Description of key information

Viscosity [HMDTMP (4-7K)]: not relevant to solid or aqueous solution

Key value for chemical safety assessment

Additional information

The requirement to test the substance for viscosity was waived in accordance with Section 1 of REACH Annex XI, as this property is not relevant or meaningful for either the solid form or aqueous solution of the substance.


Kinematic viscosity values of 7 mm²/s, 5.1 mm²/s and 1.7 mm²/s at 20°C, 37.7°C and 98.8°C respectively were reported for aqueous solution of HMDTMP (4-7K) in secondary sources to which no reliability could be assigned.
