To get the effective results it is advised to select the bleaching earth that is manufactured under rigorous quality control. Some of the best properties that a high quality bleaching earth must posses are that they are absorbent, initiate the chemical reaction and support it like an effective catalyst; it is acidic in nature and has homogenized particle distribution within its chemical structure.
The area of application of the bleaching earth is very broad and is highly used at industrial level. Some of the functions and application areas that are highly benefited due to usage of bleaching earth are that it decolorizes the color pigments within the vegetable and mineral oil. Some of the pigments up on which this agent is effective are: pheophytine, carotenoids and chlorophyll.

Usually the woven bags that are lined inside with the poly ethylene are used to store this agent. It would be best that the bag sizes should be twenty five and fifty kilogram in weight only. If larger packs are required make sure that they do not weigh more than six hundred to thousand kilograms. The effectiveness and efficiency of bleaching earth can be reduced if it is stored in place that has moisture so, make sure that you are storing the bags at cool dry place with minimal moisture present in the area around. The more precautionary measures you take the more efficient your product will perform.
