Problems solved by technology

However, liposomes are currently made into a freeze-dried state by freeze-drying technology. When two or more reagents are encapsulated at the same time, especially if the solubility characteristics of the reagents are different, the prepared freeze-dried liposomes have particle sizes Disadvantages such as inhomogeneity and poor stability

Abstract

The present invention relates to a preparation method of freeze-dried liposomes containing a hair growth composition, which is characterized in that the following steps are adopted: A. Weighing Suihua Shan double Flavonoids, quercetin-3-o-rutinoside, tetramethylpyrazine, and ricinoleic acid form a hair growth composition, and weigh hyaluronic acid oligosaccharides and sclerotin according to a mass ratio of 1:0.2-0.5 Composing a lyoprotectant; B, dissolving the hair growth composition, cholesterol and hydrogenated lecithin in ethanol, and removing the alcohol by rotary evaporation under reduced pressure after ultrasonic treatment, to obtain a lipid film containing the hair growth composition; C, adding the above lipid Add isotonic phosphate buffer solution to the membrane, sonicate and filter to obtain a liposome suspension; D, add a lyoprotectant to the above liposome suspension, freeze at -50~-10°C, vacuum for 36-72 h, the freeze-dried liposome containing the hair growth composition is obtained. The obtained freeze-dried liposome containing the hair growth composition has the advantages of uniform particle size, good stability, convenient use and good hair growth effect.

Description

technical field [0001] The invention relates to the technical field of liposome preparation, in particular to a preparation method of freeze-dried liposome containing hair growth composition. Background technique [0002] The causes of hair loss mainly include the following aspects, (1) seborrheic alopecia caused by excessive oil secretion due to low physiological function of hair follicles, hair bulbs and hair; (2) local blood circulation disorder and nutritional deficiency caused by scalp tension, resulting in Hair loss; (3) Androgenetic alopecia caused by excessive androgen acting on hair follicles and dermal papilla, resulting in slowing down of dermal papilla division; (4) Bacterial infection, genetic factors, pathological factors, injury factors, mental factors and other causes . [0003] There are a wide variety of hair growth and development products sold on the market, and their modes of action are mainly divided into two categories. One is chemical interference h...
