The ready biodegradability of succinic acid was determined by
measurement of the dissolved organic carbon content (DOC) at frequent
intervals over a period of 28 days using OECD guideline 301E. Succinic
acid, which is rapidly formed by hydrolysis of succinic anhydride
(half-life approx. 5 min), was found to be readily biodegradable. Consequently,
it can be safely assumed that succinic anhydride is also readily
biodegradable and no further biodegradation tests in soil or aquatic
systems are necessary according to REACH Annexes VIII and IX sections
