The nicotinamide-salicylic acid cocrystal comprises nicotinamide and salicylic acid molecules, and the molecular formula of the nicotinamide-salicylic acid is C0. 13 H 12 N2O4, wherein the molar ratio of nicotinamide to salicylic acid is 1:1; the eutectic is monoclinic, space group P21 / n, with cell parameters a=11.080(2)Å, b=5.0000(10)Å, c=22.820(5)Å, α=90°, β=97.60(3)°, γ=90°, V=1253.1(4)Å. 3 The differential scanning calorimetry (DSC) spectrum of the eutectic showed a characteristic endothermic peak around 142.4 ± 2 °C. This invention addresses the problems of poor stability of nicotinamide, low solubility of salicylic acid, and strong irritation in existing technologies by optimizing intermolecular interactions to form a specific crystal form, thus providing a novel raw material with superior performance for the cosmetics industry. This is achieved through the preparation of a structurally stable, simple, and chemically superior nicotinamide-salicylic acid eutectic with excellent physicochemical properties.

The present invention relates to a novel liposomal system for incorporating nano-sized edible gold particles into olive oil. This system utilizes liposomes composed of phospholipids and, optionally, cholesterol to encapsulate gold particles within the olive oil, ensuring uniform dispersion and preventing clumping or sedimentation. The liposomal formulation enhances the aesthetic appeal of the oil by maintaining a shimmering effect, and it can be further stabilized with antioxidants to prevent oxidation and prolong shelf life. The invention provides a stable, visually appealing product suitable for use in premium food items, cosmetics, and luxury gift products. Methods for preparing the liposomal system include thin-film hydration, reverse-phase evaporation, and emulsification, each ensuring effective encapsulation of the gold particles. The system is biodegradable and free from synthetic surfactants, aligning with growing demands for natural and sustainable products in the food and cosmetic industries.
