Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 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.
