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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Categories
- Category name:
- Dibasic Esters
Justifications and discussions
- Category definition:
- Methyl, butyl and isobutyl alcohol esters of adipic acid, glutaric acid and succinic acid and mixtures thereof.
- Category rationale:
- The members of the category are all alcohol esters of dicarboxylic acids. The ester bonds are effectively metabolised by the body releasing the component alcohols and acids. The difference between members involves 3 parameters: 1) the alcohol used to esterify the acids, 2) the length of the acid molecule (4C, 5C or 6C) and 3) the presence of individual esters or mixtures thereof. The toxicity profile of the members (ecotoxicity and human health toxicity and the environmental fate) is consistent. All have low acute toxicity potential, are not sensitising, are mildly irritating to eyes and upper respiratory tract (where vapour pressure allows exposure), are not genotoxic or clastogenic (in vivo) and have minimal systemic toxicity. Data are available predominantly for the methyl esters (individual and mixture), dibutyl adipate and diisobutyl esters (mixture). Within the category, read across is used to cover the higher tier human health toxicity studies predominantly. The category justification is attached in the section below.
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.
