The application of hydrated silica in the cosmetics industry is expanding from traditional thickeners to multifunctional additives. Its high specific surface area and adsorption properties make it an ideal controlled-release carrier, which can prolong drug efficacy and promote the absorption of active ingredients. For example, in sunscreen, gas-phase white carbon black can evenly disperse UV absorbers, increasing SPF value by more than 15%; In liquid foundation, its diffuse reflection property can achieve a natural matt effect, and at the same time, it can absorb excess oil and extend the makeup holding time.


In addition, hydrated silica can also be used as a friction agent in facial cleansing products. Nanoscale particles (particle size<100 nanometers) can gently remove dead skin cells, avoiding the irritation of traditional abrasives on the skin. Market data shows that the global market size of white carbon black for cosmetics will reach 520 million US dollars in 2024, with a compound annual growth rate of 8%. Among them, gas-phase products account for over 60%, mainly used in high-end skincare and makeup fields.
