Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Justifications and discussions
- Category definition:
- The sulfosuccinate category consists of di-ester sulfosuccinates. The basic structure of di-ester sulfosuccinate is succinic acid which is sulfonated and where both carbon acid groups are esterified with alkyl alcohols of different chain length or cyclic C6 rings. In the di-ester group, both carboxylic acids groups are esterified in contrast to the monoester group where only one carboxylic acid group is esterified. The alkyl alcohols of the monoester are either linear or branched.
The current group contains linear, branched and cyclic sulfoscuccinic acid di-ester sulfosuccinates with C- chain length from C4 to C13, sharing same functional groups (same general basic structure). The substances of this group do not contain other elements than C and H in their alkyl rests.
The cationic part is often sodium, but also potassium. No significant difference in properties between potassium and sodium salts is expected.

Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
