Guangdong cosmetic use of high purity nano-spherical price

First, the cosmetic nanoscale spherical high purity silica powder Overview: cosmetics nanoscale spherical high purity silica powder refined by advanced technology, an innovative method, capable of obtaining a stable and amplitude narrow particle size distribution, large surface area. Because of the spherical silica powder application play was suspended and re-dispersible in the liquid phase; the liquid can play a thickening and thixotropic; powdered products such as powder can improve the fluidity and storage stability and thus play an anti- the role of agglomeration. Because of its high specific surface area characteristic also the role as adsorbents and carrier can absorb gases, liquids, solids. Applied lipstick, face powder, foundation cream and other formulations have the following characteristics: good hydrophobicity, can enhance long-lasting property; the skin has a good affinity; good dispersion and compatibility of the oil phase. A world-class innovation and advanced technology refined spherical quartz powder used in lipstick, powder, foundation cream and other makeup products that have unique properties as follows: 1: smaller average particle size to determine its good smoothness; 2: greater than the volume of its cosmetic formulations more economical decision; 3: a narrow particle size distribution to determine its good flowability and feel; 4: large surface area so that it has good absorption of sweat, spices, nutrients and protective chemicals . Second, the nanoscale spherical high purity silica powder characteristics and applications Description: nanoscale spherical high purity silica powder is an important functional inorganic materials, with chemical stability, acid and alkali, the specific surface area is huge, gap developed, surfactants Large, high oil absorption, thickening and strong, high temperature, electrical insulation, anti-UV properties, because of its special spherical structure, so that synthetic materials with traditional materials do not have the physical and chemical properties, the use of these features , both improvement of traditional materials, but also to generate new material. For example, high-strength, super-hard, high toughness, superplastic materials and insulating materials, electrode materials and superconducting materials, special low-temperature sintering refractories, heat exchange materials, high-tech and new materials. For this reason, make nanoscale spherical high purity silica powder becomes wide range of applications, the growing market demand of powder materials. Now widely used in rubber, paints and coatings, electronic packaging materials, silicon substrate, functional chemical fiber, functional plastics, advanced ceramics, special refractories, sealants, adhesives and chemicals, pharmaceuticals and pesticides. Third, the nanoscale spherical high purity silica powder Specifications: Product Name nanoscale spherical high purity silica powder whiteness 96 ± 1 X-ray melt type high specific surface area 25m2 / g electron microscope more than 95% 0.2-1μm spherical particle accumulation rate Density 0.5 refractive index 1.46 relations with hydrophilic water softening point 1200 ℃ -1500 ℃ gravity 2.1 nanometer spherical silica powder Chemical Composition SiO2 99.9% Na <200ppm Al <50ppm Fe <20 ppm Mg <10 ppm PH value of 5 water rate <3ppm U (ppb) <0.5 Fourth, conventional spherical silica powder of high purity nano-scale basic technical parameters: spherical silica powder XCN-02 XCN-05 XCN-10 XCN-15 particle size (μm) 0.2-0.3 0.4-0.6 0.8 -1.2 1.3-2.0 specific surface area (m2 / g) 15 - 25 5 - 9 3 - 6 2 - 5 bulk density (g / cc) Loose 0.1-0.2 0.2-0.4 0.4-0.5 0.3-0.5 Tapped 0.2-0.3 0.5- 0.8 0.8-1.0 0.7-0.9 V. cosmetic nanoscale spherical high purity silica powder Features: 1, high purity: innovative purification technology to ensure the purity of our products according to different requirements by up to 99.9% were to meet the high-tech applications , silica powder of high purity requirements; 2, nanometer particle size control technology can control: Application sector size to meet the miniaturization and density deployment of technical requirements, particle size 0.2μm-2μm controllable; 3, superb ball Technology: mature, stable and reliable ball technology, so that the spherical silica powder rate jumped to 95%, and the smooth surface morphology rules; 4, low emissivity: uranium content <0.5ppb. VI Application of Guangdong Xin River Mining nanoscale spherical silica powder in the cosmetic field: we all know, for cosmetics, the requirements for ultraviolet shielding ability, the best protection is both wave ultraviolet (UVB) on the human body, also Can long-wave ultraviolet (UVA) from the protective effect. UV-shielding comprises essentially two aspects, one in front of the UV absorption, on the other hand is a reflection of ultraviolet rays. In the past, many sunscreen products use organic compounds as UV absorbers, but there are as much as possible in order to protect the skin after exposure to ultraviolet light and does not increase the amount of, will increase the incidence of skin cancer and chemical allergies and other issues, and nano-scale high-purity spherical Silica is an inorganic component, easy compatibility with the other components of cosmetics, non-toxic, tasteless, these problems do not exist, and itself is white, it may simply be colored, especially valuable is its ability to reflect ultraviolet, good stability, is After UV irradiation does not decompose, not color, it will not react chemically with other components of the formulation, the salient features of sunscreen cosmetic upgrading has laid a good foundation.
