Description:

Calcium Carbonate (CaCO₃) is a high-purity, white, odorless powder with a minimum assay of 98.0%, conforming to ACS (American Chemical Society) standards. This stable and versatile compound widely to utilize across numerous industries for its buffering, whitening, and calcium-rich properties.

This product is extensively use in industries such as pharmaceuticals, food processing, cosmetics, and manufacturing. In pharmaceuticals, Calcium Carbonate serves as a calcium supplement and an effective antacid. In food applications is using as a firming agent, acidity regulator, and dietary calcium source. The compound is also use in cosmetics as a pigment extender and absorbent. Additionally, it plays a vital role in industrial processes like plastics, paints, and paper production due to its whitening and filling capabilities.

Application(s):

  • Calcium supplement in pharmaceutical formulations

  • Antacid for neutralizing stomach acid

  • Food additive (acidity regulator, firming agent, calcium enrichment)

  • Cosmetic ingredient (absorbent and pigment extender)

  • Filler and whitening agent in plastics, paints, and coatings

  • Paper industry (improves brightness and smoothness)

  • Laboratory reagent (due to ACS-grade purity)

  • Laboratory reagent (due to ACS-grade purity)

In pharmaceuticals, Calcium Carbonate is frequently use in chewable tablets and powders formulated to treat or prevent calcium deficiencies and manage acid-related digestive issues. It also plays a role in antacid formulations to neutralize stomach acids. In the food processing industry, it serves to fortify products with calcium and adjust acidity levels in items such as canned vegetables, baked goods, and beverages.

Within industrial and cosmetic applications, this compound plays a key role in enhancing texture, consistency, and visual appearance. It is also valuable in the production of paints and coatings due to its whiteness and opacity. Additionally, it is included in toothpaste and powders for its mild abrasiveness, which supports dental health. the Calcium Carbonate is widely used in agriculture as a soil conditioner to improve pH adjustment levels and promote better crop yields.
