In accordance with section 1 of REACh (Regulation (EC) No 1907/2006) Annex XI, the dissociation constant study (required in Annex IX section 7.16) does not need to be conducted as inspection of the chemical structure shows no functional groups which are associated with dissociation behaviour at relevant environmental conditions.
There are Technical Guidance Document-approved references for the dissociation constant of glucose (α-D-Glucopyranose CASRN 492-62-6) stating a pKa of 12.46, and for maltose (α-D-glucopyranose, 4-O-α-D-glucopyranosyl- CASRN 4482-75-1) stating a pKa of 12.05. Based on this information, it is scientifically reasonable to expect that the submission substance will remain
in the undissociated form throughout the environmentally-relevant pH range of 5 to 9.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
