2012 Annual Report
Specific examples of significant developments in FY12 include the following: • Vegetable oil was biocatalytically modified with the antioxidants lipoic acid and dihydrolipoic acid to prepare new skin care products. An antioxidant plant phenol (ferulic acid) was biocatalytically esterified to polyunsaturated vegetable oils to confer high oxidation resistance, thereby allowing the vegetable oil to be utilized in skin care products. • Microbes were recently shown to be effective in oxygenating vegetable oil. This process will provide a convenient route to make high-value polymers from commodity vegetable oils. • A plant phenol (ferulic acid) was attached to milkweed oil and its antioxidant capacity in phospholipid vesicles was determined. This new molecule has potential in cosmeceutical applications. The interaction behavior of phospholipid vesicles with nano-size polymers was investigated. It was established that this new binary system can be used for topical delivery of cosmetic and pharmaceutical materials. • A catalytic method for producing an insect repellent from cuphea oil was developed. This process will provide a new market for cuphea oil. A catalyst was developed for the stabilization of the liquid product of biomass thermochemical conversion. This will allow the liquid fraction to be used to produce industrial chemicals.
