Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

water solubility
Type of information:
experimental study
Adequacy of study:
key study
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Justification for type of information:
Substance is manufactured in water and considered fully soluble at 40% solution.
On heating to reduce water content, the substance starts to decompose.
no guideline followed
Principles of method if other than guideline:
The substance is manuafactured as ca 40% in water. An attempt was made to reduce the water level (ie increase concentration > 40%), but on heating, the substance appears to decompose.
The 40% solution is fully miscible in water, with a slight haze (impurities?)
GLP compliance:
Type of method:
other: Attempt to concentrate an existing solution
Key result
Water solubility:
> 400 g/L
Conc. based on:
act. ingr.
20 °C
ca. 6.2

Sample Description Percentage Non-Volatiles

Sample as received 40.33%

Sample after drying 93.92

The results show that the product contains ~60% water, and that ~95% has been removed after drying.

Considered very soluble in water, but slight haze indicated present of less soluble fractions / impurities

Description of key information

Supplied in water at ca 40% actives.

Not possible to remove water without decomposition.

Key value for chemical safety assessment

Water solubility:
400 g/L
at the temperature of:
20 °C
