100046: Making Dihydroxyacetone (DHA) from Glycerol

Dihydroxyacetone (DHA) is used as an ingredient in sunless tanning products and in the food preparation industry. DHA’s skin coloring effect has also been examined to determine if it may benefit vitiligo patients (an uneven pigmentation of the skin); several DHA-containing products for this condition are now on the market. In recent years, the cosmetics...

060096: High Yield Glycerol to Propylene Glycol Conversion Process

The increased production of biodiesel has resulted in a concomitant increased availability of glycerol, a byproduct of the production process. As a result the price of glycerol has experienced a sharp downward spiral. Challenges have confronted biodiesel producers who have pursued Glycerol conversion to the Propylene Glycol, a more desirable and...

040081: Process for the Preparation of Lactic Acid and Glyceric Acid

Michigan State University’s invention is a process for making lactic and glyceric acid. Aqueous solutions of hexose and pentose sugars, typically glucose or fructose, are digested in the presence of strong anionic exchange resins that act as solid bases. Lactic and glyceric anions form but are bound to the ion exchange resins. The spent sugar solutions...
