What is silica microspheres used for?

What is silica microspheres used for?

The spherical particle shape scatters light helping to blur the look of fine lines and wrinkles, it is also oil absorbent. Used in high quality mineral foundations, blushers, bronzers, eye shadows and skin prep creams and lotions.

What is silica spheres?

Silica spheres are manufactured using proprietary technologies which allow the essential properties of amorphous silica to be maintained while simultaneously achieving controlled spherical shape and uniform particle size. Untreated silica spheres are typically hydrophilic and negatively charged.

What is silica microspheres?

Silica microspheres and nanospheres are composed of synthetic amorphous silica made in a laboratory batch environment. Additional advantage of silica microspheres is glass transition temperature of over 1000 degrees Celsius, which makes them suitable for high temperature applications.

How microspheres are formed?

Commonly, microspheres have been formed by coagulating the alginate solution in the form of fine droplets using calcium chloride solution (Martinsen et al. Non-aggregated alginate microspheres with an average diameter of 8 µm have been produced via an emulsification process (see Fig. 15b) by Lemoine et al. (1998).

How big is a monodisperse silica microsphere?

Monodisperse silica microspheres in dry form. Available in nominal diameters ranging from: 0.3 – 6.0µm. Inorganic supports such as silica microspheres have become increasingly important for a variety of applications, including isolation of nucleic acids, cell separation, and immuno- and DNA-based assays.

What are the uses of silica microspheres?

Inorganic supports such as silica microspheres have become increasingly important for a variety of applications, including isolation of nucleic acids, cell separation, and immuno- and DNA-based assays.

How big are the microspheres of polysciences?

Polysciences offers uniform, non-porous silica (SiO 2) microspheres available in nominal diameters of ~150nm -5µm. These particles typically have size CVs of 10-15%.
