Abstract

Background: Hydrolyzed collagen is a protein obtained from enzymatic denaturation of collagen with a molecular weight of about 10 kDa, and it has been reported to produce anti-aging properties. Delivering hydrolyzed collagen into the dermis becomes a great challenge due to its large molecular weight, so glycerosome, a deformable vesicle containing glycerol as the edge activator, was developed to carry it into the dermis layer. Objective: The study aimed to determine the effect of increasing the concentration of glycerol and hydrolyzed collagen on the characteristics and stability of hydrolyzed collagen glycerosomes. Methods: Glycerosomes were composed of soy lecithin and prepared using a thin film lipid method. The lipid film was hydrated with phosphate-buffered saline pH 5 containing different glycerol concentrations (20% and 40%) and hydrolyzed collagen (2.5% and 5%). Then, characteristic tests and stability tests were carried out. Results: Hydrolyzed collagen glycerosomes had vesicle sizes of 170-180 nm, polydispersity index of 0.253-0.279, zeta potential values of -23.70 to -26.50 mV with deformability indexes of 2.25-3.49. The highest percentage of entrapment efficiency was 85.72%, achieved with a glycerol concentration of 40%. During the stability test at 25°C for 12 weeks, the hydrolyzed collagen glycerosomes did not experience pH and entrapment efficiency changes, but it increased the vesicle size. Conclusion: The use of 40% glycerol produced more deformable vesicles than 20% glycerol in hydrolyzed collagen glycerosomes; however, a formula improvement is required to improve the stability of glycerosomes.

Abstract

Background: The success of nanoemulsion preparation is characterized by characteristics such as small droplet size, polydispersity index (PDI), and % transmittance, which are close to 100%. One of these factors is the type of oil component used. The Simplex Lattice Design (SLD) method can be used to determine the ratio of oil combinations to obtain an optimal nanoemulsion formula. Objective: The application of the Simplex Lattice Design (SLD) method can help researchers speed up the acquisition of optimal formulas without trial and error so that nanoemulsion formulas that meet specifications can be obtained. Methods: This research uses the Simplex Lattice Design (SLD) method with Design of Expert Version 13 software, with an upper limit value for oil (VCO and Palm Oil) of 2.66% and a lower limit value for oil (VCO and Palm Oil) of 0, which then The results of several formulas come out and characterization testing is carried out to get the best formula from the recommendations produced by the software. Results: The results of the Simplex Lattice Design (SLD) showed that oil affected the droplet size and PDI (p <0.05). Six optimal formulas were obtained, and after testing in the laboratory, there was no significant difference between the results of the SLD program and those of the laboratory (Sig. <0.05). Conclusion: This study shows that the Simplex Lattice Design (SLD) method is very effective.

Abstract

Astaxanthin is a potent antioxidant belonging to carotenoid compounds that is mainly produced from green microalgae Haematococcus pluvialis. Astaxanthin is beneficial for skin health as antiaging agent, but has limitations in its delivery through the skin. Astaxanthin could be formulated in nanostructured lipid carriers to improve its efficacy. The purpose of this study was to evaluate the stability and antiaging effectiveness of astaxanthin-loaded nanostructured lipid carriers (ASX-NLCs) with cetyl palmitate and soybean oil as lipid combinations at several ratios of 100:0, 90:10, 80:20, and 70:30. ASX-NLCs were synthesized using a high-shear homogenization technique. ASX-NLCs were characterized and stability evaluated after storage for 90 days. The antiaging effectiveness of ASX-NLCs was evaluated by in vitro release test using dialysis bag for 8 hours, as well as collagen density and fibroblast count evaluation on UV-induced skin aging mice for 28 days. After storage, all ASX-NLCs did not change significantly in organoleptic, pH, and particle size. However, other parameters including polydispersity index, viscosity, and entrapment efficiency experienced significant changes in some formulas. The release test showed that F4 (70:30) gave the highest cumulative release and was significantly different from F1 (100:0). The collagen density of the groups treated with ASX-NLC F3 (80:20) and F4 (70:30) increased significantly compared to the UVB control group, while the fibroblast count did not differ significantly in all groups. Overall, ASX-NLCs containing cetyl palmitate and soybean oil at ratios of 80:20 and 70:30 could improve the antiaging effect of astaxanthin which might be influenced by its better stability and release.

Abstract

Quercetin is a flavonoid compound that exhibits skin-brightening activity by inhibiting tyrosinase. However, its topical application is limited because of its low solubility. A Nanostructured Lipid Carrier (NLC) was selected as the delivery system to enhance the stability and topical efficacy of quercetin. This study aimed to optimize the combination ratio of oleic acid and Virgin Coconut Oil (VCO) as the liquid lipid phase in the NLC Blank Formulation using the Simplex Lattice Design (SLD) method. Eight blank NLC formulations were prepared using the high-shear homogenization method and were evaluated based on organoleptic properties, particle size, polydispersity index (PDI), pH, and real-time stability over 30 days. Eight blank NLC Blank Formulations showed that a balanced VCO to oleic acid ratio (5.5:4.5) produced small particle sizes (<160 nm), low polydispersity index (PDI <0.25), and good physical stability. Blank Formulations dominated by either VCO or oleic acid tended to have larger particles and lower stability, indicating that the liquid lipid ratio influenced the NLC characteristics. Optimization using the Simplex Lattice Design (SLD) method identified three optimal lipid ratios: B1 (4.86:5.31), B2 (2:8), and B3 (9:1), each with desirability values near 1. The model was validated by comparing the predicted (dry lab) and experimental (wet lab) data, which showed no significant differences in key parameters (p > 0.05), confirming the reliability of the SLD model. This approach effectively optimized quercetin-loaded NLC Blank Formulations, and the three selected Blank Formulas serve as a strong basis for developing topical quercetin NLC products.
