Key value for chemical safety assessment

Additional information

In accordance with column 2 of REACH Annex VII, the surface tension study does not need to be conducted as, based on the structure of C14-20 Aliphatics (≤2% aromatic), surface activity is not expected or predicted and surface tension is not a desired property of the material.
