The oil bleaching process. Typically bleaching is a process which contains oil mixing with bleaching agent followed by separation using filters. Upon saturation, the filters shift to regeneration while fresh filters take on the filtration duty. Saturated filters contain clay (a bleaching agent) which still has some bleaching power.

At the start of the 19th century, American companies continued an ancient tradition from the Middle East of using clay to clarify olive oil. The method included the use of fuller's earth — a bleaching earth, or clay, primarily composed of montmorillonite, a type of layered silicate — to bleach vegetable oils.

Clay bleaching is a process where we use natural mineral rich clay to bleach fibres or yarns. The process uses significantly less water than traditional chlorine-based bleaching and we recycle 90% of the water in the process. In addition, the bleached fibres and yarns are free from hypochlorous acids and other hazardous chemicals. The IndiDye ...

Animal fats and cold-pressed vegetable oils hardly need bleaching but when vegetable oils started to be produced by solvent extraction, the resulting oils were too dark to sell as such. That also holds for palm oil. Bleaching these oils with bleaching clay solved their color problems but led to the problem of spent earth disposal.

Bentonite clay is widely used in the bleaching process which is made by processing bentonite lumps and this clay is known as bleaching clay or bleaching earth. Clay that has been activated by acid has an extremely high absorption capacity, which helps eliminate impurities by binding to the surface of the clay because of its large surface area.
