The white knight we’d like to talk about today is fumed silica. Whether you are a baby, a woman or any other roles, you are connected with fumed silica to a certain degree.
The three most common-used items for baby are feeding-bottles, diapers and skin care products. Baby has intimate contact with feeding-bottles everyday as they bite the nipples to drink milk, and in the nipples there is fumed silica to increase tear-resistance property. Diapers offer comfort to baby and convenience to parents, but do you know that fumed silica plays an important role in production process of diapers? Besides, fumed silica is added to many skin care products too.
There are no ugly women,only lazy ones. During hot summer, sunlight burns, if you wear sunscreen cream in which there added fumed silica,it can protect you from UVA and UVB; Nail polish meets the needs of woman’s pursue for beauty, and fumed silica helps to increase shinning property and uniform dispersion. And fumed silica is also added into makeup powders, lipsticks and creams as ingredient.

And now , you may wonder what exactly fumed silica is. Let me explain to you.
Fumed silica, also known as colloidal silicon dioxide because it is produced in a flame, consists of microscopic droplets of amorphous silica fused into branched, chainlike, three-dimensional secondary particles which then agglomerate into tertiary particles. The resulting powder has an extremely low bulk density and high surface area. Its structure results in viscosity-increasing,thixotropic behavior and excellent dispersion property. And Fumed silica is used in many fields like rubber, plastics, coatings, adhesives, food and drugs, CMP, heat- insulation materials and so on.
After all these you must have a good understanding about fumed silica now, it seems far away, but actually around us in many ways, let’s remember this white knight.
