Fuller's Earth also called Multani Mitti is basically a chemical auxiliary factor. This tasteless and odorless clay is offered in gray or white or slightly pink color. This clay material is reckoned for its excellent decolorizing properties and good adsorption level. Multani Mitti's physical properties can be defined by Van Der Waalâs forces. This naturally found mined clay is inert when it comes in contact with chemicals. This clay consists of magnesia, lime, iron oxide, alkali and high amount of water. This non swelling type clay has excellent bleaching attributes. It is excavated from mines.
