A kind of phospholipid surfactant multi-structure liposome and preparation method thereof

Abstract

The invention discloses a phospholipid surfactant multi-structure liposome. The phospholipid surfactant multi-structure liposome comprises, by weight, 0.1-20% of phospholipid, 0.01-10% of co-emulsifiers, 0.1-10% of liquid grease, 0.05-5% of additives and the balance deionized water. The invention further provides a preparation method of the phospholipid surfactant multi-structure liposome. The preparation method includes mixing the phospholipid with the co-emulsifiers, the liquid grease and the organic additives, and heating the mixture to obtain an oil-phase component; mixing the inorganic additives with the deionized water, heating the mixture to obtain an aqueous-phase component, and adding the oil-phase component into the aqueous-phase component for homogenization; stirring and cooling at a high speed until the temperature is lowered to the room temperature, adding preservatives, and continuing to stir to obtain the phospholipid surfactant multi-structure liposome. The phospholipid surfactant multi-structure liposome has the advantages that a multi-structure can be formed by phospholipid surfactant, namely lecithin, applied in the preparation method through self-assembly, simplicity in operation is achieved, high skin moisture retention and penetrability are realized, and cosmetics made from the phospholipid surfactant multi-structure liposome are more safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and relates to a phospholipid surfactant multi-structure liposome and a preparation method thereof. Background technique [0002] The multiple structure system is a composite system in which the oil-in-water (O / W) type and the water-in-oil (W / O) type coexist. The defect of greasy feeling has both the advantages of both. In the development process of new cosmetics, multiple structure system can be said to be one of the most promising ideal systems, but due to its special structure, the general preparation method of multiple structure is a two-step method, and the operation is complicated. [0003] At present, there have been many studies on multi-structure liposomes, but the multi-structure liposomes of phospholipid surfactants have not been disclosed yet. Contents of the invention [0004] For the above-mentioned technical problems in the prior art, the invention provides a kind of phosphol...
