5 FAQs of SiO2 Nano Silica dioxide Powder/fumed silica for /hydrophilic fumed silica cas 14808-60-7

**1. What is hydrophilic fumed silica (SiO₂)?**
Hydrophilic fumed silica, or silicon dioxide (CAS 14808-60-7), is a synthetic amorphous powder produced by vapor-phase hydrolysis of silicon tetrachloride in a flame. It features a high surface area, low density, and strong hygroscopicity, making it ideal for applications requiring water absorption, thickening, or anti-settling properties. Its nano-sized particles form three-dimensional networks, enhancing stability in liquid systems.

**2. What are the primary applications of hydrophilic fumed silica?**
It is widely used as a rheology modifier, thickener, or anti-caking agent in adhesives, coatings, pharmaceuticals, cosmetics, and food. In paints, it prevents sagging; in pharmaceuticals, it improves powder flow; in personal care products, it stabilizes emulsions. Its ability to absorb moisture also makes it useful in desiccants and battery gel electrolytes.

**3. Is hydrophilic fumed silica safe to handle?**
While non-toxic, inhalation of fine particles may irritate the respiratory system. Use PPE (gloves, masks, goggles) during handling. Avoid dust generation and ensure proper ventilation. It is chemically inert but may cause dryness on skin contact. Always consult the Safety Data Sheet (SDS) for specific handling and disposal guidelines.

**4. How should hydrophilic fumed silica be stored?**
Store in a cool, dry, well-ventilated area in tightly sealed containers to prevent moisture absorption. Exposure to humidity can cause clumping, reducing dispersibility. Keep away from incompatible materials like strong acids or bases. Shelf life is typically 2+ years if stored correctly.

**5. How does hydrophilic fumed silica differ from hydrophobic variants?**
Hydrophilic fumed silica has unmodified -OH groups on its surface, attracting water and forming hydrogen bonds. Hydrophobic fumed silica is surface-treated with silanes to repel water, ideal for non-polar systems (e.g., silicone rubber). Choose hydrophilic grades for water-based applications and hydrophobic for moisture-resistant or organic solvent-based formulations.
