Chem Soc Rev 41:27802799. As a result, the synthesis produces only hydrochloric acid (which is easily removed) and silica in very high states of purity (typically > 99.9%). Langmuir 28:7598613. SiO2 Mr 60.1 [7631-86-9] DEFINITION Colloidal anhydrous silica contains not less than 99.0 per cent and not more than the equivalent of 100.5 per cent of SiO2, determined on the ignited substance. For example, 50nm particles can be concentrated to greater than 50 wt% solids while 10nm particles can only be concentrated to approximately 30 wt% solids before the suspension becomes too unstable. Precipitated silicon dioxide is silica produced in an aqueous solution at temperatures >60 C. These materials have freely accessible silanol groups (Si-OH) on the surfaces of Silica particles, rendering them hydrophilic. ACS Appl Nano Mater 3:1193311944. 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. https://doi.org/10.1016/S0001-8686(99)00008-1, Sonnefeld J, Lbbus M, Vogelsberger W (2001) Determination of electric double layer parameters for spherical silica particles under application of the triple layer model using surface charge density data and results of electrokinetic sonic amplitude measurements. If you have difficulty swallowing tablets, the tablets may be crushed or broken and added to food or a smoothie. Acc Chem Res 46:792801.

Colloidal silicon dioxide is an effective excipient for stabilizing dispersions of solids in liquids and preventing the formation of hard sediments in liquid suspensions and aerosol formulations intended for topical (rather than inhalation) use. https://doi.org/10.1039/c6tb02817a, Jia G, Cao Z, Xue H et al.

The optimum of flowability for the mixture composition was found, to correspond to empirical findings known from general literature.

Conversely, dispersions with larger average diameters have lower overall specific surface areas and are available in more concentrated dispersions. (2021) Curcumin-loaded mesoporous silica nanoparticles with dual-imaging and temperature control inhibits the infection of Zika virus. In this regard, the recommended levels of Colloidal silicon dioxide for use in coating build-up are 10 to 15% w/w, while the levels for aiding pigment suspension are 0.5 to 2.0% w/w.
