Embodiment

[0041] A hyaluronic acid freeze-dried microcapsule powder prepared from the following raw materials: 6 g of small molecule hyaluronic acid, 150 g of glucomannan, 100 g of polylaurolactam, and 4000 ml of water.

[0042] The molecular weight of the small molecule hyaluronic acid is <50KDa.

[0043] The preparation method of above-mentioned hyaluronic acid freeze-dried microcapsule powder (as figure 1 Shown, the hyaluronic acid freeze-dried microcapsule powder forms the schematic diagram), comprises the following steps:

[0044] Dissolve small molecule hyaluronic acid in water, then adjust the pH value to 7-7.5 with ammonia water, then add glucomannan and stir until dissolved, control the temperature at 37.5°C, and cross-link for 8 hours;

[0045] Then add polylaurolactam, and the homogenizer is homogenized at 3000r / min for 5 minutes;

[0046] The homogenized mixed solution was frozen at -70°C for 24 hours, and freeze-dried at -48°C for 24 hours to obtain the hyaluronic acid fr...

Abstract

The invention relates to hyaluronic acid freeze-dried microcapsule powder and a preparation method and application thereof. The hyaluronic acid freeze-dried microcapsule powder is prepared from the following raw material ingredients in parts by weight: 5 to 7 parts of micro-molecule hyaluronic acid, 130 to 170 parts of gulcomannan, 90 to 110 parts of poly-laurolactam and 3800 to 4200 parts of water. According to the hyaluronic acid freeze-dried microcapsule powder disclosed by the invention, micro-molecule hyaluronic acid with a molecular weight range of being less than50kDa is shrunk into microballoon through a freeze-drying technology, so that skin seepage force is greatly improved; when being applied to lip nursing products, the hyaluronic acid freeze-dried microcapsule powder can enter lip skin; volume can expand when meeting water to soften skin and smooth wrinkles, so that an effect of plumping lip is achieved.

Description

technical field [0001] The invention relates to the technical field of skin care products, in particular to a hyaluronic acid freeze-dried microcapsule powder and its preparation method and application. Background technique [0002] The scientific name of hyaluronic acid is hyaluronic acid (Hyaluronic acid, HA for short) or uronic acid, which is a naturally occurring substance in human tissues. It plays an important role as a matrix in the dermis of human skin, filling the space between cells and collagen fibers in the human body in large quantities. Hyaluronic acid exists in large quantities in the connective tissue and dermis of the human body. It is a transparent jelly-like substance that is full of water. 1 gram of hyaluronic acid can absorb 500C.C of water, which is equivalent to 500 times the water absorption capacity. [0003] Hyaluronic acid has been widely used in cosmetic surgery and skin care. Hyaluronic acid injection fillers and hyaluronic acid stock solutions ...
