Abstract:

We present a simple method that produces visible solid lipid microparticles (SLMs) encapsulating biogel particles for cosmetics. Biogel particles are prepared via W/O/W emulsification, and then SLMs encapsulating biogel particles are produced through continuous W/O/W multiple emulsification. We find that the presence of solid lipid affects the appearance, size, structure, crystallization properties, and physical protection of multiple emulsions, as observed through particle size analysis, fluorescence microscopy, polarized light imaging, and differential scanning calorimetry (DSC). This multiple emulsification method provides significant guidance for encapsulating various hydrophilic and lipophilic active ingredients in biogel particles and SLMs, respectively.

Micelles

Micelle formation is an intricate process that hinges on the properties of amphiphilic or amphipathic molecules and the conditions of the system in which they are found. Amphiphilic molecules, which have both hydrophilic (water-attracting) and hydrophobic (water-repelling) parts, play a critical role in this process.In aqueous environments, these molecules arrange themselves such that their hydrophilic heads are turned towards the water phase, while their hydrophobic tails are oriented away...
