  • Pharmaceutical and food compositions containing" wood alcohols" or" wood sterols" useful for lowering serum cholesterol
    Publication number: 20020183298
    Abstract: Dietary utilization of mixtures containing fatty alcohols of less than 26 carbon atoms per molecule and/or wood sterols derived from non-saponifiable compounds contained in black liquor soaps or tall oil pitch useful for lowering serum cholesterol. Food and pharmaceutical compositions containing these fatty alcohols or sterols or sterol esters are provided.

  • Fractionation process for the unsaponifiable material derived from black-liquor soaps
    Patent number: 6462210
    Abstract: The present invention relates to a fractionation process of the unsaponifiable material derived from black-liquor soaps of the cellulose industry. Through this procedure fractions that essentially contain free sterols, fatty alcohols, sterol esters and fatty alcohol esters respectively are separated. Fractions containing sterols or fatty alcohols can be used as such in the alimentary, cosmetic and pharmaceutical industries or they can be used as raw materials for transforming into other useful products.

  • Process for obtaining unsaponifiable compounds from black-liquor soaps, tall oil and their by-products
    Patent number: 6297353
    Abstract: A method for obtaining neutral compounds from black-liquor soaps, tall oil and tall oil by-products is disclosed. The method includes the steps of: (1) dehydrating black liquor soaps, neutralized tall oil, or neutralized tall oil by-products to form a dehydrated current; (2) distilling the dehydrated current in a distillation column; (3) collecting an essentially soap free distillate; and (4) collecting an essentially neutral compound free residue. Also disclosed is a method for obtaining a sterol concentrate from black-liquor soap solutions, neutralized tall oil, or neutralized tall oil by-products. In this method, a distillation operation is repeated until a current of sterols with the desired purity is obtained. The method yields a sterol concentrate with a level of purity over 96%.
