Colloidal silicas are most often prepared in a multi-step process where an alkali-silicate solution is partially neutralized, leading to the formation of silica nuclei. The subunits of colloidal silica particles are typically in the range of 1 to 5 nm. Whether or not these subunits are joined depends on the conditions of polymerization.
In 1990, the safety of synthetic magnesium silicate was reviewed by the Scientific Committee on Food (SCF) together with that of silica and the other metal alkali silicates. [10] The SCF noted that “the available data, including a number of short-term studies in two species, appear to substantiate the biological inertness of those compounds”.
Many components of naturally occurring healthy foods and vitamins have assigned E numbers (and the number is a synonym for the chemical component), e.g. vitamin C and lycopene , found in carrots. At the same time, "E number" is sometimes misunderstood to imply approval for safe consumption.
Effervescent tablets mostly come in capsules constructed for these tablets. They may contain an anti-bacterial coating and are water resistant. The cap contains a little spring-like spiral, which helps keeping the tablets in place during transportation and prevents them from breaking. The cap also contains little balls made out of silica gel. [18]
