The biodegradability of Butanedioic acid, 2,3-dihydroxy- [R-(R*,R*)]-, C12-13-branched alkyl esters was assessed in a CO2 -evolution test according to the OECD 301B guideline (July 1992). The degradation extent of the test item was 64.2 % within 35 days after acidification. The degradation after 28 days was 54.0%. According to the Revised Introduction to the OECD Guidelines for Testing of Chemicals, Section 3 the test item can be classified as inherently biodegradable.
