Bleaching Earth
Bleaching Earth is a fine, highly adsorptive clay material derived primarily from bentonite or montmorillonite, and in some cases from attapulgite or sepiolite. It is typically activated using acid treatment to enhance its surface area and pore structure. It is widely used to remove color, contaminants, impurities, and odors from edible oils, fats, waxes, petroleum products, and various industrial fluids. Its high adsorption capacity, non-toxic nature, and effectiveness in filtration make it essential in food processing, chemical industries, cosmetics, and waste treatment applications.
Calcium Carbonate (Uncoated)
Calcium Carbonate (uncoated) is a naturally occurring mineral compound composed primarily of calcium, carbon, and oxygen with the chemical formula CaCO₃. It appears as a fine white powder or granules, widely used as a filler, pigment, and functional additive across various industries.
