Description
Calcium carbonate absorbs oil extremely well, so it can be found in cosmetics and skin care products as an oil control/mattifying ingredient. You’ll also find calcium carbonate in toothpastes as a mild abrasive.
Calcium carbonate can be hot or cold processed. As it is insoluble you can add it to either the heated oil or heated water phase of an emulsion—I’d probably choose the water phase as calcium carbonate is quite absorbent, so it seems wise to put it in the larger phase. In cosmetics, grind it in with everything else.
Stored somewhere cool, dark, and dry, calcium carbonate should last at least five years.
Very effective oil absorber/mattifying ingredient, inexpensive.
