Therapeutic Goods (Listing) Notice 1999 (No. 4) Due to the small pore size, APIs can be stabilised in amorphous form within a polymer or lipid carrier. Thus, in the strictest sense, the term colloidal silica applies to stable dispersions (or sols) consisting of discrete particles of amorphous silica having sizes of between 5 and 100 nm. Silica in oral drugs as a possible sarcoidosis-inducing antigen The absence of adverse health effects is best summarized in the recommendations of the OECD SIDS Initial Assessment Report (OECD, 2004) which states Colloidal silicon dioxide is currently of low priority for further work due to the low exposure potential for humans. (2016) Amino acid-based anti-fouling functionalization of silica nanoparticles using divinyl sulfone. As a result, the synthesis produces only hydrochloric acid (which is easily removed) and silica in very high states of purity (typically > 99.9%). A low shear blender (gravity drop or mechanical mixers) is preferred to prevent the addition of excess energy into the blend. Purity and reliability of raw materials are just two of the many challenges you face as a manufacturer of pharmaceutical products. Soft Matter 10:71828.

A key feature of gels obtained with colloidal silica that makes them different from other types of gels (for instance, those obtained with hydrocolloid gums) is that their viscosities show little dependence on temperature. For convenience, the different forms of Silica can be divided into three main groups as shown in the chart below: At the fundamental level of Silicas chemical properties is the Silica tetrahedron (SiO4), which consists of a central Silicon cation covalently bonded to four oxygen atoms, arranged in the shape of a tetrahedron. Two-thousand year-old Roman cement contains amorphous silica from volcanic ash which helps give it high strength and durability. Dispersions containing large colloidal silica particles (> 50 nm) are normally white. Subtledifferences in particle morphology, particle size, and ionicspecies can make all the difference.

In addition, it has the widest ranging surface area, and its aggregate size can be as small as the actual size of the primary particle. 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. They do not cause silicosis. These are shown in the chart below: Synthetic amorphous silicon dioxides are further divided into three main types, namely: Even though they share the same chemical structure and synthetic origin, Synthetic silicas exhibit different properties, as briefly reviewed below: Pyrogenic silicon dioxide is produced using a high-temperature process in which silicon tetrachloride is vaporised in an oxygen-hydrogen atmosphere according to the following chemical reaction: The raw materials used in the silica production process are all inorganic and very pure.

Under these circumstances, interactions with silanol groups may occur, especially for substances having amine or hydroxyl groups. This temporal sequence strongly implicates anhydrous colloidal silica as the cause The method and conditions have been fine-tuned and now permit production of many types of synthetic silica that are structurally and characteristically different, including exhibiting internal pore volume/specific surface area, larger particle sizes, and water content.
