- Conclusions:
- The granulometry of 2,2’-[propane-1,3-diylbis(oxy)]bis(3’’,5,5’’-tri-tert-butyl-5’-methyl-1,1’:3’,1’’-terphenyl-2’-ol)was determined in accordance with European Chemicals Agency (ECHA), Guidance on information requirements and chemical safety assessment, Chapter R.7a, Endpoint specific guidance, May 2008.
Light microscopic examination revealed that the product contains many particles < 100 µm. The fraction < 100 µm resulting from sieving on a 100 µm sieve is 16.5%m/m.
From the whole product 4.4 wt% is < 10 µm and 2.7% is < 5 µm. - Executive summary:

Additional information
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.
