Sunscreen cream containing cannabidiol lipidosome and preparation method

Abstract

The invention discloses a sunscreen cream containing a cannabidiol lipidosome and a preparation method. The sunscreen cream is prepared from the following components in percentage by weight: 0.5 to 2percent of cannabidiol lipidosome, 0.5 to 8 percent of titanium dioxide, 1 to 8 percent of diethylamino hydroxy benzoyl hexyl benzoate, 0.5 to 10 percent of isoamyl 4-methoxycinnamate, 1 to 5 percentof ethylhexyl salicylate, 0.5 to 1.5 percent of ethylhexyl palmitate, 2 to 6 percent of glycerin monostearate, 0.5 to 2.5 percent of cetostearyl alcohol, 1 to 10 percent of glycerinum, 1 to 5 percentof butanediol, 0.1 to 1 percent of allantoin, 0.1 to 2 percent of tocopheryl acetate, 0.01 to 0.5 percent of xanthan gum, 0.01 to 0.2 percent of EDTA-2Na, 0.01 to 0.1 percent of preservative, and thebalance deionized water. According to the sunscreen cream containing the cannabidiol lipidosome and the preparation method provided by the invention, the nanoscale cannabidiol lipidosome is prepared by adopting a lipidosome embedding technique, so that the water solubility and the stability of cannabidiol (CBD) are improved, meanwhile, a transdermal absorption effect of the CBD is effectively promoted, the CBD can quickly penetrate through a skin surface layer, directly arrives at a skin deep layer and is slowly released, and the efficacy is durable. The sunscreen cream containing the nanoscale cannabidiol lipidosome provided by the invention has a better sunscreen effect and is capable of effectively scavenging free radicals and delaying skin aging, and the skin is fresh and cool withoutgreasy feeling after being applied with the sunscreen cream.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a sunscreen containing cannabidiol liposome and a preparation method thereof. Background technique [0002] Human skin, especially the facial skin, will damage the epidermal cells after excessive exposure to ultraviolet rays. After ultraviolet rays penetrate into the skin, harmful free radicals will be produced. These free radicals will damage the elastic fibers of the skin, cause skin relaxation, accelerate aging, and stimulate melanin. Increased secretion of cells, resulting in increased synthesis of melanin, resulting in pigmentation, such as dark spots, freckles, chloasma and other spots that increase, increase, and darken; under strong exposure, it can also cause skin inflammation, burns, and severe It can cause skin relaxation, roughness and wrinkle formation, telangiectasia, and erythema; it can also reduce skin immune function and form skin cancer or precanc...

Problems solved by technology

[0005] One object of the present invention is to use liposome technology to prepare nano-sized cannabidiol, solve the problem of cannabidiol being insoluble in water, and increase the transdermal absorption effect of cannabidiol while improving its water solubility and stability. It allows CBD to quickly and effectively penetrate the surface of the skin, reach the deep layer of the skin and release CBD slowly, and the effect is obviously longer
