Activated BLeaching earth:

Activated Bleaching Earths are used to adsorb colored pigments (carotenoids, chlorophyll) and colorless pigments (phospholipids) from edible and inedible oils. This process is called "bleaching" and thus serves both cosmetic and chemical purposes.

Bleaching reduces color, whereby very clear, almost water white oils are produced that meet with consumer expectations. Bleaching also stabilizes the oil by removing colored and colorless pigments which tend to "destabilize" the oil, resulting in oils that rancidify more easily if they are not removed.

The current and expected long term trend favors the use of highest possible bleaching efficiency clays with this process because:
i) The smaller amounts of the high activity wash clay is needed to produce desired refined oil properties meaning that lower inventories can be maintained by the oil refiner.
ii) Refined oil losses depend somewhat on the amount of clay used because less high activity clay needs to be used and therefore oil losses are lower.
iii) High Activity wash clays lowers residual acidity ensures no reversions of colours in oil after treatment.
