Using Mica Powder in Soap Making

Yes, mica powder listed for cosmetic use can generally be used in soap making. The key difference between the sizes (A, B, C, D) lies in the visual effect they create in the soap.

• Smaller particle sizes (like Size A, around 30 microns, or even smaller like 9 microns): These tend to blend more smoothly into the soap base, providing a pearlescent or satin-like sheen rather than distinct sparkle.
• Medium particle sizes (like Size B, around 60-80 microns): These offer a noticeable shimmer or glitter effect.
• Larger particle sizes (like Size C, around 150-160 microns, and Size D, around 250-350 microns): These provide a more pronounced sparkle or glitter effect, with individual particles being more visible.

Therefore, you can use any size depending on whether you want a subtle shimmer or a strong sparkle in your soap. For example, products like Mica Powder (9 Micron, Silane Coated) would give a very smooth effect, while Bronze Gold Glitter Mica (Size B, 60 Micron), Silver Sparkle Mica (Size C, 160 Micron), or Silver Super Sparkle Mica (Size D, 300 Micron) would provide increasing levels of sparkle.

Always ensure the mica powder is cosmetic grade and suitable for use in rinse-off products like soap.
