Finest Mica Powder for Serums and Lotions

Based on the available options, the finest grade of mica powder is Mica Powder (9 Micron, Silane Coated). With a particle size of 9 microns, it is the most finely ground among the listed mica powders, making it highly suitable for use in serums and lotions where a smooth, non-gritty texture is desired.

Other fine grades that might also be considered for similar applications include:

• Mica Powder (13 Micron, Matte, Silane Coated)
• Mica Powder (20 Micron, Methicone Coated)
• Mica Powder (20 Micron, Silane Coated)

These finer grades disperse easily and spread evenly on the skin, providing softness, lightness, and natural skin coverage.
