Calcium Carbonate 1 kg

A mineral whose real job happens far beyond the makeup counter

Calcium carbonate is mined from chalk, limestone and marble deposits, then ground into a fine powder used across dozens of industries worldwide. The largest global demand for this raw material comes from construction chemistry, plastics and rubber manufacturing, pulp and paper production, agriculture, food processing and pharmaceuticals, while the cosmetic industry uses it in smaller but steady volumes as a base component of the Mineral fillers section.

In construction chemistry, calcium carbonate serves as a filler in putties, plasters, paints and sealants, reducing the amount of costly binders needed without compromising the strength of the final mix. In plastics and rubber manufacturing it is introduced into the polymer matrix as a functional filler that increases rigidity and lowers raw material cost. The paper industry relies on finely ground calcium carbonate both as a bulk filler for the sheet and as a coating pigment, producing a denser and smoother surface.

Agriculture uses this mineral for soil liming, since applying the powder reduces soil acidity and improves the uptake of nitrogen and phosphorus by plants, and also as a feed supplement for livestock and poultry to compensate for calcium deficiency in the diet. In food production, calcium carbonate is recognized as additive E170, used to fortify flour, baked goods, dairy and soy products with mineral calcium. Pharmaceutical manufacturers rely on it as a component of antacid formulas and as an inert tablet filler that gives the dosage unit its required volume and shape.

In cosmetic manufacturing the powder is valued for its ability to absorb excess sebum and give dry blends an even, dense texture. It is introduced into formulas for mineral powders, eyeshadows, dry deodorants and tooth powders as an absorbent and bulking agent. It pairs well with Mika Sericite with Carnauba Wax, 1 kg, which adds slip and easy blendability to a blend, and with Mineral makeup base matt, 100 g when a dense matte pressed texture is needed. For compressed formats, a small amount of Magnesium Stearate, 5 g is often added alongside calcium carbonate, acting as a binder that keeps a pressed powder from crumbling.

In dry cosmetic blends calcium carbonate typically makes up between 10 and 40 percent of the formula by weight, and it is added during the dry mixing stage without heating, since the material is thermally stable and requires no special temperature control. Store the powder in a tightly sealed container in a dry place away from direct moisture, as the mineral is hygroscopic and can clump if exposed to water vapor. The 1 kg package size fits small-batch studio production of mineral makeup lines and lab-scale test formulas before moving to larger production runs.
