The seeds produced by several species of Shorea in Borneo contain an edible oil whose physical and chemical properties are remarkably similar to cocoa butter. These seeds are known commercially as "illipe nuts", and large quantities are collected and sold internationally to be used in the manufacture of chocolate, soap, candles, and cosmetics. West Kalimantan exports tens of thousands of tons of illipe nuts. [NOTE: The triglyceride fractions in illipe nut oil occur in similar proportions to those found in cocoa butter, and the oil can be blended with chocolate without altering the texture, gloss, or taste of the original confection. The higher melting point of illipe nut oil makes it especially useful as a chocolate hardener, i.e. so that it melts in your mouth, not in your hand].
