Description of key information
Paracetamol is a solid chemical. In order to calculate surface tension it shall have to be dissolved either in water or an organic solvent. In this case, there is every likelyhood that the surface tension that shall be calculated of the solution of paracetamol might actually erroneously reflect the measurement of surface tension of the solvent (either water or organic solvent). Hence this end point was considered for waiver considering the technical difficulty in surface tension measurement of solid paracetamol.

Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
