Sorbitol Special® plasticizers are sorbitan-sorbitol based soft gel plasticizers. They enhance the capsule finish gloss for a premium appearance, help to prevent leakage, provide consistent pharmaceutical quality, and extend shelf life by maintaining a proper moisture balance within the capsule shell. Sorbitol special MDF 85 is designed for PEG fill systems. It is ideal for APIs that are incompatible with Water and Glycerin (ex. Ibuprofen, Diphenhydramine).
