Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

It is concluded that Butanedioic acid, 2,3 -dihydroxy-[R-(R*,R*)]-C12 -13 -branched alkyl esters will not accumulate in the body.

Additional information

The BCFBAF version 3.01 programme of the EPI Suite software (v 4.10) was used to predict either a log BCF of 2.19 (BCF of 153 L/kg wet-wt) (linear C12 -component), 2.26 (BCF 181 L/kg wet-wet) (branched C12 -component), 1.78 (BCF 59.7 L/kg wet-wt) based on a regression estimate or a log BAF of - 0.01 (BAF of 0.966 L/kg wet-wt) (linear C12 -component), log BAF -0.01 (BAF = 0.972 L/kg wet-wt) (C12 -branched component), log BAF -0.04 (BAF = 0.91 L/kg wet-wt) (C13 -branched component) based on the Arnot-Gobas upper trophic model both using the smiles codes of Butanedioic acid, 2,3 -dihydroxy-[R-(R*,R*)]-C12 -linear alkyl esters, Butanedioic acid, 2,3 -dihydroxy-[R-(R*,R*)]-C12 -branched alkyl esters and Butanedioic acid, 2,3 -dihydroxy-[R-(R*,R*)]-C13 -branched alkyl ester representing Butanedioic acid, 2,3 -dihydroxy-[R-(R*,R*)]-C12 -13 -branched alkyl ester. Because the Arnot-Gobas upper trophic model takes also into account metabolism of the substance by the organism it is lower. The QSAR-data are supported by the results of the pharmacokinetics. Butanedioic acid, 2,3 -dihydroxy-[R-(R*,R*)]-C12 -13 -branched alkyl esters will be hydrolysed, absorbed and efficiently metabolised into water soluble metabolites, which is supported by the molecular structure of Butanedioic acid, 2,3 -dihydroxy-[R-(R*,R*)]-C12 -13 -branched alkyl esters and its physico-chemical properties.

It is concluded that Butanedioic acid, 2,3 -dihydroxy-[R-(R*,R*)]-C12 -13 -branched alkyl esters will not accumulate in the body.
