Industrial Applications, Safety & Customization Insights
1. Is silica safe in food? Does it cause harmful side effects?
Synthetic amorphous silica powder is officially certified safe and non-toxic, and will not produce any chronic side effects when formulated in accordance with regulatory parameters. KOSNANO’s high-purity silica is 100% compliant with FDA 21 CFR 172.480 regulations, with heavy metal impurities well below 10 ppm. When added to food bases or vitamin supplements at a strict addition rate of 0.1% to 1.0%, it provides optimal anti-caking properties while ensuring optimal powder flowability.
2. How can surface-treated silica powder optimize its dispersibility in cosmetics and skincare products?
To eliminate the industrial bottleneck of powder agglomeration, we employ advanced organic surface treatment technology to create highly hydrophobic and oleophilic silica powders to meet the needs of diverse customers. Our nano-engineered silica particles, with an average particle size of 10 to 40 nanometers, blend perfectly with the oil phase, preventing your cosmetics from leaving white residue or clogging skin pores. For high-end cosmetics and sunscreens, we typically recommend adding 1.5% to 3.0% modified silica powder, which imparts a silky smooth feel and enhances the overall stability of the emulsion.
3. Why choose our high-purity fumed silica and precipitated silica for industrial reinforcement?
KOSNANO’s fumed silica forms a strong triple-bonded hydrogen network, increasing the scratch resistance and hardness of industrial coatings by up to 15%. For elastomer compounds and green automotive tire manufacturing, our highly dispersible precipitated silica, with a DBP oil absorption value of up to 2.5 cm³/g, effectively reinforces the rubber matrix. This technological advantage can reduce tire rolling resistance by 20% to 30%, directly translating to a 3% to 8% improvement in fuel efficiency for commercial vehicles.
