Product Name: OSA-Vitamin C
Synonyms: Octenyl succinic anhydride–Vitamin C,
Description: Starches modified with octenyl succinic anhydride (OSA) have been used in a range of industrial applications, particularly as a food additive, for more than half a century. Interest in these products has grown in recent years as a result of new methods and applications becoming available. Due to a combination of OSA’s hydrophobic and steric contribution and starch’s peculiar highly branched macromolecular structure, these starch derivatives display useful stabilizing, encapsulating, interfacial, thermal, nutritional and rheological properties. Vitamin C (L-ascorbic acid), a known enhancer of collagen deposition, has also been identified as an inhibitor of elastogenesis. SA, applied in 50-200 μM concentrations, stimulates production of both collagen and elastic fibers in all tested cultures. They also encourage inclusion of SA into therapeutic combinations with collagenogenesis inhibitors to prevent formation of dermal scars and keloids.
