Attempts in part I of the dissertation were to develop microemulsion systems using medium chain triglyceride, Captex 300, deionized water (H2O), and TPGS as surfactant for the oral delivery of protein drugs or poorly water soluble drugs. Pseudo-ternary phase diagrams were constructed to elucidate the phase behavior of systems composed of medium-chain triglyceride and water with TPGS as main surfactant, polysorbates (Tween 20, Tween 40, Tween 60 and Tween 80) as adjuvant surfactants, and polyethylene glycols (PEG 400 and PEG 600) and polyols (ethanediol, 1,2-propanediol, 1,3-propanediol, 1,3-butanediol, 1,4-butanediol and glycerin) as cosurfactants.

The effects of different of categories surfactants, the proportion of surfactant and cosurfactant , the chain lengths of alcohol and alkane, temperatures and pH values on the W/O microemulsion phase areas are systematically studied in the dissertation. SEM and laser scatting techniques are used to verify particles'sizes of W/O microemulsion. Consequently, a system TritonX-100/n-C〓H〓OH (weight ratio 1: 1)/C〓H〓/H〓O is obtained which is a stable system with relatively large W/O microemulsion phase area.
