Reference
Endpoint:
water solubility
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
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.
Qualifier:
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:
no
Type of method:
other: Attempt to concentrate an existing solution
Key result
Water solubility:
> 400 g/L
Conc. based on:
act. ingr.
Temp.:
20 °C
pH:
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.

Conclusions:
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
