Description of key information

In accordance with column 2 of REACH Annex VIII Nr, the study does not need to be conducted as the substance is readily biodegradable and highly insoluble in water (see Sect. 4.8).
At neutral conditions, half-life of diisotridecyl adipate was estimated to be 4.6 years
At pH 8 the half-life was estimated to be 169 days at 25°C

Key value for chemical safety assessment

Half-life for hydrolysis:
4.6 yr
at the temperature of:
25 °C

Additional information

The total basic (pH 8) hydrolysis rate constant for diisotridecyl adipate at 25°C was calculated to 0.04737 L/(mol*s) using the program HYDROWIN v 2.00 of US EPA EPI Suite v4.00. The half-life was estimated to be 169 days (24 weeks).


At neutral condition (pH 7) the half-life was estimated to be 4.6 years.
