Science
Mechanism of Action
This silicate functions physically within formulations, providing structural integrity and thickening properties. On the skin, it serves as a physical barrier or texturizer, offering absorbent and opacifying effects rather than biochemical activity.

Formulation
Stability
This silicate exhibits negligible solubility at neutral pH; its solubility and structural stability are highly dependent on pH and Calcium/Silicon ratio. It is most stable in alkaline environments, commonly formulated at pH up to 11 in skin-tightening products.
Conflicts
- Acids (may cause precipitation or decomposition of the silicate structure)
- Polyvalent cations (can act as coagulants)
- High concentrations of sodium (can form insoluble salts at high pH)
Safety
Safety Profile
Concluded safe as used in current practices when formulated to be non-irritating. A caution exists for incidental inhalation of mined silicates in spray products, though the 6% maximum refers to non-spray applications like foundations.
