Polydisperse suspensions can also be synthesized and have roughly the same limits in particle size. Most colloidal silicas are prepared as monodisperse suspensions with particle sizes ranging from approximately 30 to 100 nm in diameter. Therefore, the mean diameter of the resulting synthetic amorphous silica particles, as used, is typically in the micron range and well above 100 nm. https://doi.org/10.1021/cm3001688, Hadipour Moghaddam SP, Saikia J, Yazdimamaghani M, Ghandehari H (2017) Redox-responsive polysulfide-based biodegradable organosilica nanoparticles for delivery of bioactive agents.

Too much or too little glidant usually results in sub-optimal results, as does over-blending since it leads to full coverage of particles, thereby reducing flowability. It also provides pastes and ointments with the desired consistency and prevents separation of the various formulation ingredients, making it a highly versatile material with multiple pharmaceutical and cosmetic applications. It can also be used as a carrier or adsorbent for active ingredients and to improve incorporation or release characteristics.

The order of addition of the ingredients and dispersion time is not critical. Finally, the viscosity of sodium silicates is much higher - closer to that of a syrup, while colloidal silicas have viscosities close to that of water. After opening, it should be stored in the refrigerator at 2-8C with the cap tightly closed during storage. Many plants use silica to stiffen stems for holding fruit and to form external needles for protection. 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. Whether or not these subunits are joined together depends on the conditions of polymerization. While liquids may be absorbed a little quicker, the disintegration of tablets or capsules is generally quite fast once the digestive process begins. https://doi.org/10.1021/ac0693619, Nakamura M (2010) Approaches to the biofunctionalization of spherical silica nanomaterials. https://doi.org/10.1021/j100812a002. https://doi.org/10.1039/c3sm52401a, Grasso D, Subramaniam K, Butkus M et al.
