Based on the chemical nature of synthetic amorphous calcium silicate
(inorganic structure and chemical stability of the substance), no photo-
or chemical degradation is expected.
The water solubility is
limited, for the calcium silicate tested (see 4.8) about 4 % under test
As shown for silica,
hydrolysis to a
minor, not yet quantifiable degree is limited to a gel-layer surrounding
the silica/silicate particle in aqueous medium. Hydrolysis of silica has
been shown to be largely independent of the pH between 1.1 and 8.9,
contributing to the limited dissolution of silica in water. Therefore,
similar to silica, hydrolysis is assumed to play no substantial role in
the dissolution process of calcium silicate.
