description Product Description
Used as a filtration aid, especially in the food and beverage industry, to clarify liquids like beer, wine, and syrups by trapping fine particles. Commonly used in industrial processes to filter oils, chemicals, and pharmaceuticals. Acts as a carrier for active ingredients in pesticides and liquid fertilizers due to its high porosity and absorbency. Employed in the manufacturing of dynamite as a stabilizer to absorb nitroglycerin. Also found in some cosmetics and toothpastes as a mild abrasive. Used in laboratories for sample preparation and as a drying agent.
