Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Linearity

Linearity could be shown over the whole calibration range from 0.05 to 1.5 mg/L (correlation coefficient R = 0.992).

Recovery

In duplicate analysis, a recovery rate of 136% in average was determined.

Description of key information

<0.05 mg/L at 20 °C, pH = 6.28

Key value for chemical safety assessment

Additional information

The water solubility of the substance fatty acids, C16-18 even numbered and C18-unsatd. triesters with propylidynetrimethanol (former CAS 57675 -44 -2) was determined according to EU method A.6 using the column elution method.
