Preparation method of vitamin C-loaded silk fibroin/hyaluronic acid composite nanofibers

The invention provides a preparation method of vitamin C-loaded silk fibroin / hyaluronic acid composite nanofibers. The preparation method comprises following steps: silk fibroin is dissolved in deionized water, and is stirred at room temperature until silk fibroin is dissolved completely so as to obtain a silk fibroin solution with a mass concentration of 30 to 35%; hyaluronic acid is dissolved in deionized water, and is stirred at room temperature until hyaluronic acid is dissolved completely so as to obtain a hyaluronic acid solution with a mass concentration of 2 to 4%; the silk fibroin solution and the hyaluronic acid solution are mixed so as to obtain a silk fibroin / hyaluronic acid mixed solution; sodium L-ascorbyl-2-phosphate is dissolved in the silk fibroin / hyaluronic acid mixed solution, and the mixture is stirred uniformly so as to obtain a mixed electrospinning solution; and the mixed electrospinning solution is subjected to electrospinning so as to obtain the vitamin C-loaded silk fibroin / hyaluronic acid composite nanofibers. The vitamin C-loaded silk fibroin / hyaluronic acid composite nanofibers are capable of simulating the components of extracellular matrix in composition, and the preparation method is capable of endowing the vitamin C-loaded silk fibroin / hyaluronic acid composite nanofibers with excellent physiological properties.

Skin softener containing cannabidiol nano liposomes and preparation method thereof

The invention discloses a skin softener containing cannabidiol nano liposomes and a preparation method thereof; the skin softener is characterized by comprising, by mass, 0.1-1% of cannabidiol nano liposomes, 5-10% of glycerol, 0.5-3% of hyaluronic acid, 0.1-1% of ceramide, 1-5% of trehalose, 0.001-0.01% of phenoxyethanol, and deionized water. Cannabidiol (CBD) has many physiological effects, suchas antibacterial and anti-inflammatory effects, anti-acne effect and anti-oxidation effect, but is insoluble in water, which limits its application and bioavailability. The fat-soluble CBD is made into the nano cannabidiol liposomes, so that the water solubility and stability of the CBD are improved, the transdermal absorption effect of the CBD is promoted, the CBD penetrates the skin surface quickly and effectively and reaches the deep layer of the skin to slowly release, and the efficacy of the CBD is longer. The skin softener according to the invention is clear and transparent in appearance, free of precipitation or CBD crystal precipitation and free of alcohol, hormone, pigment, essence and other components, has a soft and safe formulation, and has the multiple effects of efficient moisture preservation, antibiosis and anti-inflammation, acne relief, oxidation resistance and the like.
