Various solubilization techniques have been developed to enhance the bioavailability of hydrophobic drugs. One of the solubilization techniques is preparation of microemulsion. Microemulsion is a potential carrier in drug delivery system because it has many advantageous characteristics. In this research, hydrophobic drug was made in a dosage form of oil in water (O/W) microemulsion using ketoprofen as a model and investigated the influence of adding starch hydrolisates with dextrose equivalent (DE) 35-40 in variety concentrations (0,0%; 1,5%; 2,0%; 2,5%) to the stability of this microemulsion system. This microemulsion consisted of isopropyl miritate as oil phase, tween 80 and lechitin as surfactants, ethanol as cosurfactant, propylene glycol as cosolvent, starch hydrolisates DE 35–40 as stabilizer, and water as external phase. The evaluation was stability test both phisically and chemically. The result showed that the stability of microemulsion system increased significantly by adding starch hydrolisates DE 35-40 at 2,5%.

Lycopene and resveratrol are well-known for their high bioactivity, anti-inflammatory effects, and strong antioxidant properties. The combination of lycopene and resveratrol was synergistic in the potentializing immunity of the mammal body. In this study, the scalable co-encapsulation of lycopene and resveratrol into polymeric nanoparticles was performed using lycopene extracted from ripe gac fruit. These nanoparticles exhibited excellent water dispersion and spherical morphology with average particle diameters of 66.102 nm. The particle size was proportional to the lycopene/resveratrol ratio. The combinative use of lecithin and Tween® as surfactants and the use of a polylactide-polyethylene glycol copolymer as an encapsulation agent generated well-defined lycopene/resveratrol nanoparticles although the total content of these active compounds reached 12%. The stability of lycopene was enhanced when combined with resveratrol and antioxidants such as vitamin E and butylated hydroxytoluene. After 3 months of storage at −16 °C, the lycopene content in the lycopene/resveratrol nanopowder remained at ∼95%.

Solar UV radiation damages human skin by affecting skin tone and resiliency and leads to premature aging (photoaging). The skin damage is caused by the activation of the AP-1 transcription factor, which increases matrix metalloproteinase (MMP) expression and collagen degradation. An increase of interleukin (IL)-6 is also correlated with the activation of MMP-1 expression. β-thujaplicin has shown both acaricidal and antimicrobial activities. Also, β-thujaplicin has been shown to be protective against apoptosis due to the oxidative effects of UV irradiation. However, the effect of β-thujaplicin on UVB-induced MMPs had not been investigated. In this study, after UVB exposure, MMP-1 and IL-6 production in human skin fibroblasts was examined in the presence of β-thujaplicin, vitamin C, and vitamin E. The expression of MMP-1, MMP-3, tissue inhibitor of metalloproteinase (TIMP-1, TIMP-3) and procollagen mRNA was also investigated. Results showed that UVB-induced MMP-1 production was suppressed by the β-thujaplicin treatment in a dose-dependent manner, but not by vitamin C and vitamin E. β-thujaplicin also prevented the up-regulation of MMP-1 and MMP-3 mRNA. Moreover, the UVB-suppressed procollagen gene expression was restored to normal by β-thujaplicin. Neither UVB nor β-thujaplicin affected the mRNA expression of TIMP-1 and TIMP-3. The IL-6 production induced by UVB was lower in β-thujaplicin treated fibroblasts than in the controls. In conclusion, this study shows the capability of β-thujaplicin in preventing MMP-1 production due to UVB irradiation via inhibition of MMP gene expression. Importantly, the UVB-suppressed procollagen gene expression can be restored to normal by β-thujaplicin. These findings indicate that β-thujaplicin is a promising and potent agent to inhibit UVB-induced MMP-1 and MMP-3 gene expression in skin fibroblasts.

There is an upsurge of interest in improving the stability and prolong the scent holding time of fragrances in cosmetic industry. In this study, to encapsulate the orange essential oils (OEO), nanoethosomes were constructed with optimized proportions of ethanol, water, soybean phosphatidylcholine (SPC), Tween 80, and palm oil sucrose esters (PSE). The controlled-release behavior of nanoethosomes was then studied concerning physicochemical stability, microstructure, and olfactory sensation. The sustained-release effectiveness of the nanoethosomal fragrances was influenced by particle size and OEO amount of specific formula. Herein, there was a positive correlation between particle size and sustained-release effectiveness. In particular, the mean diameter of nanoethosomal orange fragrances (nano-OFs)–prepared by EO-ethanol-water-SPC-Tween 80-PSE (3–7:25:72–68:2:1.0:0.1) and 3%, 5%, and 7% OEO–was 68.6±3.6, 79.5±4.5 and 87.3±6.9 nm, respectively. The results of olfactory sensation and GC-MS analysis showed that these fragrances could sustainedly release the aromatic compounds to yield satisfactory smell longer than that of the conventional orange fragrance. Furthermore, the nano-OF made of 5% EO yield a satisfactory smell more than 3 h, which was 3 times of that of the conventional orange fragrance. This fragrance was stable when stored at 4 °C (>1 year) and 25 °C (>10 months). The knowledge gained from this study will be helpful to develop nanoethosomal fragrances or perfumes for commercial use.

In this study, a proniosome-based transdermal drug delivery system of lovastatin was developed by coacervation phase separation method. On the basis of the pilot trials, a 3-factor, 3-level Box–Behnken design was employed to characterize the effect of Cholesterol, soya lecithin and Tween 80 on dependent variables (particle size, entrapment efficiency, and drug release). TEM analysis of optimized formulation has demonstrated the presence of individual Proniosomes in spherical shape. Lovastatin optimized proniosomal formulation F1 shown better particle size and percentage entrapment efficiency and drug release of 99.49% within 24h in slow and controlled manner when compared with control. Kinetic analysis of drug release profiles showed that the systems predominantly released Lovastatin in a zero-order manner with a strong correlation coefficient (R2= 0.9990). The particle size and Zeta potential of the optimized lovastatin proniosomal gel was found to be 138.82 nm and -11.4 mV respectively. Optimized batch of Proniosomes was used for the preparation of Lovastatin - based proniosomal hydrogel by incorporating hydrated Proniosomes to Carbopol matrix to enhance the stability and viscosity of the system. The enhanced skin permeation for prolonged time may lead to improved efficacy and better patient compliance.
