About Bleaching Earth

Understanding the fundamentals of bleaching earth

Product Overview

The Powerful Decolorizing Clay

Bleaching Earth is an activated or natural adsorbent clay used primarily for purifying and decolorizing edible oils, fats, and industrial fluids.

Through acid activation, the clay's surface area and adsorption capacity are enhanced to remove pigments, phospholipids, soaps, and other impurities from oils.

02

What is acid activation?

Acid activation is a chemical treatment with mineral acids that increases the surface area and adsorption capacity of natural bentonite clay.

Chemical Enhanced Active
03

What is oil retention?

Oil retention is the amount of oil that remains in the spent clay after filtration. Lower oil retention (<30%) means less oil loss and better economics.

<30% Economic Efficient
04

What dosage rates are typical?

Typical dosage rates range from 0.5% to 4% depending on the oil type, color load, and desired final color.
