Sorbitol

Definition and Structure Mannitol, Sorbitol, and Xylitol are organic compounds that are typically derived from a sugar by reduction.7 These ingredients occur naturally, however, they are most commonly obtained industrially by the hydrogenation of sugars. The ingredients in this group are all simple sugar alcohols and are in that way, structurally similar. The definitions of the ingredients included in this review, as given in the Dictionary, are provided in Table 1. Mannitol and Sorbitol are differentiated solely by the relative orientation of their hydroxyl groups, while Xylitol differs in chain length (Figure 1). Figure 1. Mannitol, Sorbitol, and Xylitol Physical and Chemical Properties Mannitol, Sorbitol, and Xylitol are white, water-soluble powders or granules (Table 2).8-10 Although Mannitol and Sorbitol are stereoisomers, the two sugar alcohols differ in melting points and water solubility.  Distributed for Comment Only -- Do Not Cite or Quote Method of Manufacture The methods below are general to the production and purification of Mannitol, Sorbitol, and Xylitol; no methods specific to cosmetic ingredient manufacture were found in the literature or submitted as unpublished data. Traditional synthesis of Mannitol and Sorbitol involves the high-pressure hydrogenation of fructose/galactose mixtures in an aqueous solution.7 When using this method, Raney nickel is used as a catalyst. Alpha-fructose is converted to Mannitol, and beta-fructose and glucose are converted to Sorbitol. The hydrogenation of a 50:50 fructose/galactose mixture generally results in a 25:75 mixture of Mannitol and Sorbitol. Sorbitol itself can also be produced via similar glucose hydrogenation methods.11 Glucose from wet milling plants is used as the feedstock for the Sorbitol production. The glucose solution is … [kırpıldı - bölüm toplam 17323 karakter]
