Background: Cosmetics are the products used to beautify the skin. Emulsion is a fine dispersion of two or more immiscible liquids. Sphaeranthus indicus is claimed to be used for skin beautification in folk medicine. Multiple emulsion was formulated containing the extract of S indicus flowers.
Aims: This research study indicates that extract of S indicus flowers contains sufficient amount of polyphenols and also possess good antioxidant activity with mushroom tyrosinase inhibition activity.
Method: Further, stable multiple emulsion was developed and stability testing was performed for 180 days by keeping the multiple emulsion at 8°C ± 1, 25°C ± 1, 40°C ± 1, and 40°C ± 1 with 75% ± 1 RH. Parameters checked were color change, phase distribution, viscosity, droplet size and size distribution, pH determination, and electrical conductivity. Sun protection factor (SPF) was determined which also showed promising results. Skin testing on human volunteers was done for 3 months after biosafety profiling of the most stable multiple emulsion.
Results: This also showed remarkable effects. Skin erythema, melanin, and sebum were reduced. Skin hydration and elasticity were increased. There was also reduction in the number of skin large and small skin pores. Skin spot area was also reduced by the use of multiple emulsion loaded with S indicus flower extract. ANOVA test showed that all the effects produced on skin were significant, ie, P ≤ .05.
Conclusion: A stable multiple emulsion was developed which produced significant cosmetic effects on human skin.

Skin inflammation represents a hallmark of many skin conditions, from psoriasis to eczema. Here, we present a novel microemulsion formulation for delivering a low dose of potent immunosuppressant, tacrolimus, to the skin for local inflammation control. The efficacy of topically delivered tacrolimus in controlling skin inflammation can be enhanced by packaging it into microemulsions.

In this study, the improvement mechanism of yeast proteins (YPs) with the ultrasonic and pH shifting treatment on the emulsion stability was investigated through the solubility, protein structure and interface behavior of YPs. Compared with only pH shifting or ultrasound treatment, the solubility of YPs with the combined treatment of ultrasonic and pH shifting was increased significantly. The soluble protein content of pH-U400 reached 85.

Large-amount encapsulation and subsequent expressing are common characteristics for many biomedical applications, such as cosmetic creams and medical ointments. Emulsion gels can accomplish that, but often undergo exclusive, complex, multiple synthesis steps, showing extremely laborious and non-universal. The method here is simple via precisely interfacial engineering in homogenizing a nanoparticle aqueous dispersion and a polymer oil solution, gaining interfacial 45° three-phase-contact-angle for the nanoparticle that can bridge across oil emulsions' interfaces and ultimately form interconnected macroscopic networks.

Background: To compare the impact of two different lipid emulsions, specifically a soybean oil-based emulsion and a multiple oil emulsion (soybean oil, medium-chain triglycerides, olive oil, and fish oil, SMOF), on serum metabolites of very low birth weight (VLBW) infants using untargeted metabolomics analysis.
Methods: A comparative study was conducted on 25 VLBW infants hospitalized in neonatal intensive care units (NICU) of Hangzhou Women's Hospital in 2023. The infants were divided into the SMOF group (13 cases) and the soybean oil group (12 cases) based on the type of lipid emulsion used during parenteral nutrition.

Bone, cartilage, and soft tissue regeneration is a complex process involving many cellular activities across various cell types. Autografts remain the "gold standard" for the regeneration of these tissues. However, the use of autografts is associated with many disadvantages, including donor scarcity, the requirement of multiple surgeries, and the risk of infection.
