Description of key information

Surface tension (hexamethylcyclotrisiloxane): Not relevant

Key value for chemical safety assessment

Additional information

The substance hydrolyses rapidly in contact with water (half-life = 23 min at pH 7 and 25°C). Therefore, the surface tension study is considered technically unfeasible and is also of very limited relevance. The hydrolysis products, L3-diol and dimethylsilanediol, are not expected to be surface active on the basis of chemical structure.
