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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Oxidation reduction potential (OPR) in mV
- Key result
- Remarks on result:
- other: Glycolic acid 70% solution can act as reducer in the presence of strong oxidisers (structural assessment).

Theoretical assessment: glycolic acid can act as a reducer in the presence of strong oxidisers.
Applicant's summary and conclusion
- Conclusions:
- Glycolic acid 70% solution can act as reducer in the presence of strong oxidisers.
- Executive summary:
Glycolic acid 70% solution can act as reducer in the presence of strong oxidisers.
In aqueous solution the reduction potential is a measure of the tendency of the solution to either gain or lose electrons when it is subject to change by introduction of a new species. A solution with a higher (more positive) reduction potential than the new species will have a tendency to gain electrons from the new species (i.e. to be reduced by oxidizing the new species) and a solution with a lower (more negative) reduction potential will have a tendency to lose electrons to the new species (i.e. to be oxidized by reducing the new species). Glycolic acid has reducing potential (the tendency to lose electrons) only in solution.
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.
