Ascorbyl tetraisopalmitate (VC-IP) is a novel form of ascorbic acid characterized by reduced water solubility due to complete acylation with palmitate. This study investigated the potential cosmetic application of VC-IP when encapsulated in lyotropic liquid crystal nanoparticles (VC-IP LCNPs) by using a high-pressure homogenization (HPH) method. The particle size, zeta potential, and polydispersity index (PDI) of the obtained VC-IP LCNPs were determined as 158.

The behavior of water in concentrated ionic solutions, including supersaturated conditions, is crucial for numerous material and energy conversion processes and fundamental research. All electrolytes whether they "structure-make" or "structure-break" the water structure lead to slower water motion. This study investigates the structure and dynamics of aqueous NaCl solutions across a wide range of concentrations.

In this study an in situ forming gel for curcumin and piperine delivery is investigated as a long-lasting strategy in the local treatment of inflammatory and degenerative joint disease, such as osteoarthritis and rheumatoid arthritis. Particularly glyceryl monooleate, in association with phosphatidylcholine and ethanol, were employed. Different ratios between excipients were tested, with the aim to obtain a liquid form suitable for subcutaneous injection, gaining a semisolid consistency in contact with biological fluids.

The endosomal escape of lipid nanoparticles (LNPs) is crucial for efficient mRNA-based therapeutics. Here, we present a cationic polymeric micelle (cPM) as a safe and potent co-delivery system with enhanced endosomal escape capabilities. We synthesized a cationic and ampholytic di-block copolymer, poly (poly (ethylene glycol) methacrylate--hexyl methacrylate)--poly(butyl methacrylate--dimethylaminoethyl methacrylate--propyl acrylate) (p(PEGMA--HMA)--p(BMA--DMAEMA--PAA)), via reversible addition-fragmentation chain transfer polymerization.
