Interference cosmetic pigment. This pigment does not appear to have much colour until it is placed over a background. It picks up various pearlescent shades of blue (light & dark) depending on either a dark or white background.
Beautiful shade of starlight blue.
Add it to soaps, lotions, lip gloss, cosmetics, etc. and you will see a fine shimmer and pearlescent colour.
Add it to clear soap (about 1/2-1 teaspoon per pound) with a drop of liquid dye (try green, blue or yellow) for outstanding colour! Absolutely brilliant!
