Moreover, monomethylsilanetriol has an anti-aging effect, and stabilizes the orthosilicic acid in nails, skin and hair to prevent nail hardness, skin wrinkles and hair-fall.
Equation (2) shows that [K.sup.+] and [Mg.sup.2+] are replaced by [H.sup.+] from montmorillonite, kaolinite, and orthosilicic acid generated at the same time.
3, the carbon dioxide gases are absorbed by silicate to produce orthosilicic acid, which avoids foaming of PU/ silicate composite and enhances the mechanical properties.
Alkalinity also can be derived from dissolved silicate (Snoeyink and Jenkins, 1980) because , orthosilicic acid resulting from the dissolution of calcium silicate can ionize to yield H3Si[O.sub.3.sup.-]
