Introduction

Galleon Earth is the registered trade name of activated bleaching earth manufactured by Mizusawa Industrial Chemicals Ltd., Japan, and has been widely used as a refining agent for various animal and vegetable fats and oils, fatty acids, lubricating oils and waxes.

Galleon Earth

Galleon Earth is obtained by treating High Purity Montmorillonite Clay with mineral acid (sulphuric acid); as a result alumina, iron oxide, magnesia and calcium oxide are eluted partially. Thus obtained Galleon Earth is a porous aluminium silicate compound having an excellent adsorbability owing to a large pore diameter, a large pore volume and a large specific surface area. 

Properties of Galleon Earth

Generally speaking, strongly acid-treated product is suitable for refining at lower temperature and weakly acid-treated product is suitable for refining at higher temperature. Galleon Earth, because of its inherent properties, has a decided superiority for adsorbing coloring matters and impurities contained in various fats and oils, mineral oils, waxes and so on.

Grades of Galleon Earth

• V2 Super
  Bleaching earth of the highest bleachability and filterability for difficult-to-bleach oil fats and oils such as castor oil, palm oil, linseed oil, rapeseed oil, fish oil, soybean oil, cotton seed oil and oilve oil. It exhibits high performance in both chemical and physical refining for palm oil.

• V2
  High-quality special grade for difficult-to-bleach general fats and oils, in particular, castor oil, palm oil, soybean oil, rapeseed oil, linseed oil, rice bran oil, cotton seed oil, fish oil and beef tallow.
