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

Hydrophilic fumed silica (SiO₂, CAS 14808-60-7) is a high-purity, amorphous silicon dioxide powder produced via flame pyrolysis. With a nanometer-scale particle size and large surface area, it is widely used as a thickening agent, anti-settling additive, and rheology modifier. Below are five frequently asked questions about this material:

**1. What is hydrophilic fumed silica used for?**
Hydrophilic fumed silica is a versatile additive in industries like coatings, adhesives, sealants, pharmaceuticals, and cosmetics. It improves viscosity, prevents sagging in paints, enhances texture in creams, and acts as a free-flow agent in powders. Its high surface area and hydroxyl groups enable strong interactions with polar substances like water.

**2. How does hydrophilic differ from hydrophobic fumed silica?**
Hydrophilic fumed silica has unmodified surface hydroxyl (-OH) groups, making it water-attracting. Hydrophobic variants are surface-treated with silanes to repel water. The choice depends on the application: hydrophilic grades suit water-based systems, while hydrophobic grades are ideal for non-polar matrices like oils or solvents.

**3. Is hydrophilic fumed silica safe to handle?**
While amorphous silica (CAS 14808-60-7) is generally recognized as safe, prolonged inhalation of fine dust may cause respiratory irritation. Always use PPE (masks, gloves) and ensure proper ventilation. It is non-toxic but classified as a nuisance dust; comply with OSHA guidelines for airborne particulates. Note that crystalline silica (e.g., quartz) is carcinogenic, but fumed silica is amorphous and not classified as such.

**4. How does particle size affect performance?**
Smaller primary particles (7–40 nm) increase surface area (50–400 m²/g), enhancing thickening and reinforcement. Finer grades provide higher viscosity control, while coarser particles offer better flowability. Performance depends on dispersion quality—proper mixing ensures optimal particle interaction.

**5. Can hydrophilic fumed silica be dispersed in water?**
Yes, it disperses readily in polar liquids like water due to its hydrophilic nature. Pre-mixing with a high-shear mixer or ultrasonication ensures uniform distribution. Over time, reagglomeration may occur, so stabilizing agents or continuous agitation are recommended for long-term suspensions.

Hydrophilic fumed silica’s adaptability and performance make it indispensable in formulations requiring precise rheology control and stability. Always consult technical datasheets for grade-specific properties.
