Problems solved by technology

[0005] The existing anti-aging liposome products developed by a single mechanism, the liposomes are easy to adhere to the inside of the keratinocyte wall, destroy the lipid bilayer structure, and cause drug leakage, so liposomes have difficulties in drug transport, and Anti-aging liposome products can only exert a certain anti-aging effect, and the effect is relatively single and not obvious

Abstract

The invention discloses a polypeptide liposome containing fatty acid, and a preparation method thereof. The polypeptide liposome comprises an oil phase and a water phase, and the oil phase comprises hydrogenated lecithin, palmitic acid, stearic acid, behenic acid and caprylic / capric triglyceride; and the water phase contains, by weight, acetyl hexapeptide-8, acetyl dipeptide-1 cetyl ester, palmitoyl tripeptide-5, tetradecyl aminobutyryl valamido urea butyrate trifluoroacetate, glycerol, butanediol and water. The preparation method of the polypeptide liposome comprises the following steps: mixing, heating and melting the oil-phase raw materials to obtain the oil phase, mixing, heating and melting the water-phase raw materials to obtain the water phase, and then mixing and homogenizing the oil phase and the water phase to obtain the fatty acid-containing polypeptide liposome. The preparation method has the characteristics that the skin infiltration capacity of the liposome is improved, and all-around synergistic interaction is realized.

Description

technical field [0001] The invention relates to a polypeptide liposome, in particular to a fatty acid-containing polypeptide liposome and a preparation method thereof. Background technique [0002] Skin wrinkles are caused by the joint action of endogenous and exogenous factors. Among them, exogenous factors include ultraviolet radiation, smoke and harmful chemicals, etc., and the reactive oxygen species (ROS) generated by their contact with the skin will directly damage the DNA of skin cells and the collagen, elastin or mucopolysaccharide molecules of the extracellular matrix , so that the skin becomes thinner, the basement membrane of the epidermis and dermis is damaged, the number of cells and the number of blood vessels decrease, resulting in the generation of skin wrinkles; Decreased, decreased skin hydration capacity, decreased concentration of proteoglycan and hyaluronic acid in the skin, decreased moisture in the dermis, decreased activity of dermal fibroblasts, and...
