Dodecenylsuccinic acid, compound with 2,2',2''-nitrilotriethanol (1:1)

Water solubility

Link to relevant study record(s)

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
