Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Half-life in soil for acetic acid is 2 days (20 C).
Key value for chemical safety assessment
- Half-life in soil:
- 2 d
- at the temperature of:
- 20 °C
Additional information
The target substance is an UVCB substance consisting of adipic acid, di-anhydride with bis(acetic acid) (ca. 57 %), acetic acid (ca.32.5 %), acetic anhydride (ca. 7.1 %), adipic anhydride (ca. 1.5 %) and oligomeric adipic anhydrides (ca. 1.0 %). Therefore information for biodegradation in soil is based on read-across data from the main constituents.
Two studies are available from soil biodegradation; Nowak 1990 and Sharabi & Bertha 1993. Both studies are non-GLP and doesn't follow OECD guidelines. Study by Nowak (1990) was conducted with acetic acid and the half-life in soil was determined as 2 days in temperature of 20 deg. C. Study by Sharabi & Bertha (1993) was conducted with adipic acid but no half-life value was calculated. Result from these studies indicate that the final hydrolysis products of the target substance degrade rapidly in soil.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
