Endpoint summary
Administrative data
Description of key information
The substance is observed as solid white crystals.
Melting point: 118°C.
The substance decomposes before boiling (260°C).
Relative density at 20ºC: 1.217 ± 0.010.
The particle size distribution (Granulometry) study does not need to be performed as the substance is produced, marketed and used in a non-solid or granular form.
Vapour pressure at 25.3°C, 32.4 °C and 44.5°C was below 0.1 mBar (10 Pa).
The partition coefficient logPow at 22 ± 1ºC: 0.6 ± 0.40 (This does not fall within a range of ± 0.3 as prescribed by the guideline).
Water solubility at 20ºC > 1000 g/l for all three buffer solutions. (pH 4.0, 7.0 & 9.0).
The surface tension at 20ºC is 71.2 ± 2.5 mNm.
The substance is a solid and therefore no flash point has been determined.
The substance has a melting point below160°C and therefor auto flammability has not been determined.
Not highly flammable.
The substance is not explosive.
The substance is not oxidising.
Additional information
Dehydrated sample of IPP1 -Na (produced by adding aqueous NaOH to IPP1).
Although the substance is defined as a solid, it is always produced as an aqueous solution.Therefore Chapter 9 and 10 in the CSA/CSR are based on the aqueous solution rather than the solid.
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.
