Elevate your purification processes with our high-performance Bleaching Earth, also known as Activated Clay. This essential adsorbent is widely used for the refining and purification of various oils, fats, and liquids. Engineered for superior decolorization and contaminant removal, our Bleaching Earth ensures the highest quality end-products, enhanced stability, and extended shelf life for your valuable materials.
Our Bleaching Earth is derived from select natural bentonite and other clay minerals, meticulously processed and, for activated grades, acid-treated to significantly enhance its adsorptive capabilities. It is the go-factor for industries demanding exceptional clarity, purity, and minimal undesirable components.
Bleaching Earth operates through a powerful adsorption mechanism. Its unique porous structure and high surface area, especially in acid-activated forms, possess a strong affinity for polar compounds. When oils and fats come into contact with the Bleaching Earth, undesirable substances (pigments, gums, trace metals, etc.) are selectively adsorbed onto the clay's surface through physical and chemical interactions. This leaves behind a purer, lighter-colored product that meets stringent quality specifications.
Our Bleaching Earth is indispensable in a wide range of industries:

Note: Specific values and test methods will be provided in the product's Certificate of Analysis (CoA) and Technical Data Sheet (TDS).
Our Bleaching Earth is available in secure and durable packaging options to meet your logistical and storage requirements:
Store Bleaching Earth in a cool, dry place, away from direct sunlight, moisture, and strong oxidizing agents. Keep bags tightly sealed to prevent moisture absorption, which can reduce efficacy. Always use appropriate personal protective equipment (PPE), including dust masks and gloves, when handling the product, as it is a fine powder that can generate dust. Refer to the Material Safety Data Sheet (MSDS) for detailed safety information.
