"The love of beauty is universal". Since ancient times, humans have never stopped the pursuit of beauty. From the use of animal oils by people in primitive communes to the constant emergence of new makeup materials in the modern world, cosmetics science and technology have also been evolving with the tide of times.
In recent years, more and more nano materials are being introduced to the production of cosmetics. As a non-toxic, odorless, chemically inert and inorganic nano material that boasts good thickening, anti-settling, dispersion and anti-sagging properties, fumed silica (also known as pyrogenic silica, colloidal silicon dioxide) has become a material that is sought after by cosmetics manufacturers and widely used in the production of common cosmetic products such as eye creams, lipsticks, skin care products, nail polishes, mascara creams.  
In addition to significant thickening effects, adding fumed silica into ointment, gel and cream products also helps significantly increase the stability and thixotropy of the products. Other than having a three-dimensional "chain-like" structure (dendritic structure), fumed silica also has a large number of silicon hydroxyls on its surface. By virtue of such silicon hydroxyls, two types of hydrogen bonds can be formed within the fumed silica, one between silicon dioxides by which silicon dioxides jointly form a silica network, and the other between the silicon hydroxyls and substrates (such as polar liquids or polymer materials, etc.). Through the aforementioned effects, the silicon dioxides and the substrates jointly form an Intertwined network which enables the material to have better thickening properties.
Ointments, gels, creams with fumed silica are easier to apply evenly and smoothly without the sensation of dryness; adding hydrophobic silica soot to emulsion-type skin care products can significantly increase the products' viscosity and reduce the sense of greasy feeling, making users feel more refreshed.
Produced by ,HUBEI HUIFU NANOMATERIAL CO.,LTD. former company name : Yichang Huifu Silicon Material Co., Ltd., series products such as HL-150, HL-200 hydrophilic fumed silica and HB-151, HB-132 hydrophobic fumed silica have been widely used in many industries due to advantages including good transparency as well as better thickening, thixotropy, anti-settling and dispersion properties.
