Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

8.7
Remarks on result:
other: estimated value
Remarks:
Fatty acids, C10-20 neo, reaction products with diethylenetriamine is an UVCB substance. The main component is a mixture of bis-amides, derived from the amidation reaction between Fatty acids, C10-20-neo-, and diethylenetriamine. Fatty acids, C10-20-neo- is a complex mixture of tertiary carboxylic acids, with C19 being the main component. Due to its complex composition, methods for the experimental measurement of adsorption/desorption property are technically not feasible. On the basis of the very low water solubility and its chemical nature, the substance is expected to have a high ability to absorb to soil. The hydrophobic interactions have been evaluated as the most dominant type of interactions between the substance and the soil organic carbon. The amide groups are not ionized at environmental pH values, then the extent of ionization and the more specific interactions of ionized species with the soil are negligible. Estimated Log Koc value for the main component (bis amide derived from the amidation reaction between C19 neo fatty acid and diethylenetriamine) is 8.7 (corrected Log Koc estimated from Kow, KOCWIN v.2.00, September 2010; US EPA).
