Silica Microspheres are cosmetic-grade spherical silica particles used to improve texture, oil absorption, and light diffusion in formulations. They provide a soft, silky feel and mattifying effect, enhancing both skincare and makeup products.
Absorbent, texture enhancer, mattifying agent, light diffuser, bulking agent
Product Type(s):
Typical Usage Range:
1–15% in powders; 0.5–5% in emulsions and creams
Provides a soft-focus effect to reduce the appearance of fine lines and pores, improves slip and spreadability in powders and creams, absorbs excess oil for a matte finish; widely used in color cosmetics and skincare for a silky texture
Primary Components:
Amorphous silicon dioxide (SiO₂) microspheres
Generally recognized as safe; avoid inhalation of fine silica dust; non-crystalline cosmetic-grade silica is considered non-toxic
Preferred Extraction Method:
Synthetic amorphous silica (precipitated or fumed) formed via controlled hydrolysis of silicates
Use only cosmetic-grade amorphous silica (not crystalline quartz); microsphere grades provide better texture and light-diffusing properties
