Description of key information

Waiving of study:
In accordance with column 2 of REACH Annex IX, the determination of the dissociation constant (required in section 7.10) does not need to be conducted as the substance disodium disilicate (delta-crystalline) is hydrolytically unstable (see 5.1.2 Hydrolysis).
