Product Overview


Product Description

What is bleaching earth?

Bleaching earth, also known as activated clay or fuller’s earth, is a highly versatile and widely used industrial material. It is primarily used in the refining and purification processes of various oils, fats, and waxes.

Bleaching earth is a type of clay that is highly adsorbent, meaning it has the ability to attract and hold onto impurities. The
most common source of bleaching earth is bentonite, a clay made from volcanic ash. However, other types of clays, such as montmorillonite, attapulgite, and kaolin, can also be used.

The main purpose of bleaching earth is to remove color pigments, unwanted odors, and other impurities from oils and fats. Itaccomplishes this through a process called adsorption, where the clay particles attract and bind with these undesirable substances. Additionally, bleaching earth can remove or reduce trace metals, free fatty acids, and peroxides, improving the quality and stability of the refined products.

Advantages of Bleaching Earth

***Effective Color Removal: Bleaching earth has excellent adsorption properties, enabling it to effectively remove color pigments and unwanted hues from oils, fats, and waxes. It helps enhance the visual appeal of refined products by producing lighter and clearer end results.

***Odor and Flavor Improvement: In addition to removing color, bleaching earth also aids in the removal of undesirable odors and flavors. It can eliminate rancid or off-notes, improving the overall sensory qualities of the refined products.
***Adsorption of Impurities: Bleaching earth has a high adsorption capacity, allowing it to attract and bind with a wide range of impurities. It effectively removes contaminants such as chlorophyll, carotenoids, residual soap, free fatty acids, peroxides, sulfur compounds, and heavy metals, to name a few.

***Versatility and Compatibility: Bleaching earth can be used in the refining processes of various oils, fats, and waxes, making it highly versatile. It is compatible with different types of clays, which enables manufacturers to choose the most suitable material for their specific applications.
***Cost-Effectiveness: Bleaching earth is a cost-effective solution for refining processes. It offers an efficient and economical method of purifying oils, fats, and waxes, as it helps reduce the need for additional processing steps and equipment.
***Shelf Life Extension: By removing impurities and stabilizing the refined products, bleaching earth contributes to an extended shelf life. It helps prevent oxidation and degradation, ensuring that the products maintain their quality and freshness over a longer period.
***Sustainability: Bleaching earth is a naturally occurring material, primarily derived from clay sources. It is non-toxic and
environmentally friendly. Additionally, it can be regenerated and reused for multiple cycles, reducing waste and minimizing the environmental impact.
