Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

In accordance with section 2 of REACH (REGULATION (EC) No 1907/2006) Annex XI, the study does not need to be conducted as pure gluconic acid is a solid.  The substance is only placed on the market in the form of an aqueous solution and the viscosity will depend upon the concentration of the solution.  Thus it is technically not feasible to determine a viscosity for gluconic acid.

Key value for chemical safety assessment

Additional information

The viscosity of a 50% solution in water is reported in a Safety Data Sheet as 30 mPa.s.
