Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The relative density was determined for the THPS 100% dry active substance to be 1.53 at 21.5°C and for the THPS 75% aqueous solution to be 1.39 at 22°C.
The value determinated for the commercial THPS 75% aqueous solution is used for chemical safety assessment.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.39
Additional information
The relative density of solid THPS dry active substance (100%) and THPS 75% aqueous solution were determined according to OECD 109, EU Method A.3 (Relative Density) and US EPA/FIFRA subdivision D§63-7 guidelines under GLP.
The relative density of THPS dry active substance was determined relative to distilled water using a pycnometer at 21°C (294K). Four determinations were made, giving a result at 1.530 (g/mL) as mean of 1.532, 1.487, 1.576 and 1.523.
The relative density of THPS 75% aqueous solution was determined relative to water at 4°C using a pycnometer at 22°C. Two determinations were made, giving a relative density of 1.392 (g/mL), mean of 1.392 and 1.392.
The value 1.39 g/mL determinated for the commercial THPS 75% aqueous solution is used for chemical safety assessment.
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.
