In the cosmetics industry, its reflective and refractive properties make mica an important ingredient in blushes, eyeliner eye shadow, foundation, hair and body glitter, lipstick, lip gloss, mascara, moisturizing lotions, and nail polish.
The great part about using micas in CP is that they don’t clump at all. The colors are so smooth and wonderful to work with. The bummer part about using micas in CP is that they have a higher usage rate than pigments and natural colorants. They also do provide just a tinge of sheen in CP, and that looks sophisticated. Another bad thing about micas in CP, is that, since they are coated in FD&C, some of them are not stable in CP soap and do require testing.
