The drug release percentages at 10, 30, 60, and 90 min were selected as responses. The independent factors were the components of oil-based capsule including beeswax (X 1), hydrogenated coconut oil (X 2), and soybean oil (X 3). A three-factor-constrained mixture design was used to prepare the systemic model formulations. The purpose of this study was to develop and optimize an isotretinoin oil-based capsule with specific dissolution pattern. Tsai, Pi-Ju Huang, Chi-Te Lee, Chen-Chou Li, Chi-Lin Huang, Yaw-Bin Tsai, Yi-Hung Wu, Pao-Chu Isotretinoin Oil-Based Capsule Formulation Optimization The IL-ZDDP formulation consistently outperforms the ZDDP-only formulation in friction reduction and wear protection, and results from the bench and engine tests are well correlated.« less Results were benchmarked against those of another experimental engine oil with almost the same formulation except using ZDDP only without the IL (similar total phosphorus content). In addition, the forthcoming standardmore » Sequence VIE engine dynamometer test was then conducted to demonstrate improved fuel economy. The prototype engine oil was first evaluated using tribological bench tests: AW performance in boundary lubrication (BL) and friction behavior (Stribeck curves) in elastohydrodynamic, mixed, and BL. An experimental SAE 0W-16 engine oil was generated containing a combination of IL and ZDDP with equal phosphorus contribution. In this research, we investigated whether this synergy manifests in formulated engine oils. We have previously reported an oil-miscible phosphonium-organophosphate ionic liquid (IL) with an effective anti-wear (AW) functionality when added to a base oil by itself or combined with a conventional zinc dialkyldithiophosphate (ZDDP) for a synergistic effect.
