Embodiment Construction

[0013] Preparation of carboxymethyl inulin:

[0014] Weigh 3g inulin (see figure 1 a and figure 2 ), add 30mL isopropanol, stir at room temperature for 20 minutes, then add 10mol·L -1 NaOH solution, 1.26 mL each time, continued to stir for 45 minutes, dissolved 3.6 g of monochloroacetic acid in isopropanol, added to the reaction solution in portions, and continued to react for 3 hours at room temperature. After the reaction, filter with suction, wash the precipitate with methanol for 3-4 times, and vacuum freeze-dry. The obtained product is a light yellow powdery solid which is easily soluble in water. (see figure 1 b and image 3 )Depend on figure 1 Schematic diagram of the structural formulas of inulin a and carboxymethyl inulin b shown, wherein, n=2-70; R=-CH 2 COO.

[0015] The application of the compound carboxymethyl inulin as a hygroscopic humectant:

[0016] 1) Determination of hygroscopic activity: Grind carboxymethyl inulin into fine powder, vacuum freeze-d...

Abstract

The invention relates to the daily chemical field and a medicine industry, in particular to application of carboxymethyl synanthrin compound. The carboxymethyl synanthrin compound can be used as a moisture absorption and retention agent. The carboxymethyl synanthrin has strong capacity of moisture absorption and retention, can be used as a substitute for expensive hyaluronic acid in a moisture retention agent of cosmetic, and substantially reduces cost.

Description

technical field [0001] The invention relates to the field of daily chemicals and the pharmaceutical industry, in particular to the application of a compound carboxymethyl inulin. Background technique [0002] Moisturizing agent is an indispensable and important ingredient in cosmetics, and it plays an important role in cosmetics: (1) Improve dry skin: Hygroscopic moisturizing agent can significantly increase the water content of the skin and increase skin elasticity. (2) Prevent skin damage and promote damaged skin repair. There are many kinds of humectants, among which hyaluronic acid (Hyaluronic acid, HA), a humectant derived from organisms, is an excellent humectant. HA has no irritation to human skin, and when applied in cosmetics, it has a moisturizing effect on the skin, making the skin elastic and smooth, and delaying skin aging. One source of hyaluronic acid is extracted from animal tissue, and the other is extracted from microbial fermentation broth. However, hya...
