Mineral makeup shimmers and glows, thanks to mica pigment powders. Many people mix their own mica powders because it is an all-natural, hypoallergenic and inexpensive alternative to store-bought makeup. Mica pigment powders provide the nontoxic color base and sparkle for eye shadow, blush, foundation and bath products. Using the correct ingredients, anyone from a casual hobbyist to the professional makeup artist can make a glittering palette of mica powders.
Add the titanium dioxide, magnesium stearate and bismuth oxychloride to the mortar. Using one hand to steady the mortar, grind the powders together with the pestle. This mixture provides the base for the mica powder.
Determine what color mica powder you want to create. Select and measure the iron oxides pigments that mix to make that color. Blend the sericite mica and half of the iron oxide pigments with the base powder. Add more pigment until the mixture is the desired shade.
Put 1 to 2 drops of jojoba oil in the powder and blend thoroughly. The oil acts as a binding agent and maintains the consistency of the mica powder.
Transfer the mica powder to the plastic jar and secure the lid tightly. Label the jar with the date. After six months, discard any unused powder.
