Applicant's summary and conclusion
- Conclusions:
- the pour point of the substance(representative sample) is ca 258K
- Executive summary:
The freezing of the substance was determined by measuring the pour point of a representative sample. The mean pour point determined was 258K
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).
