Embodiment 1

[0040] In this example, the target compound hydroxypropyltrimethylammonium chloride chitosan-carboxypolysaccharide complex salt was synthesized according to the above synthetic route.

[0041] 1) Preparation of hydroxypropyltrimethylammonium chloride chitosan: Weigh 4.83 g chitosan and disperse it in 20mL isopropanol to swell at room temperature, add 2,3-epoxypropyltrimethylammonium chloride 13.59 g, reacted at 55-65°C for 9 hours; then added 60mL of methanol for alcohol precipitation, the resulting precipitate was washed with 85% ethanol and suction filtered to obtain a filter cake, and dried to constant weight to obtain hydroxypropyltrimethyl chloride ammonium chitosan;

[0042]2) Preparation of hydroxypropyltrimethylammonium chloride chitosan-carboxymethyl chitosan salt: 3.42 g of hydroxypropyltrimethylammonium chloride chitosan obtained above was dissolved in 20 mL of deionized water, and then Weigh 3.72 g carboxymethyl chitosan and dissolve it in 74 mL deionized water, t...

Embodiment 2

[0044] The difference from Example 1 is:

[0045] 1) Preparation of hydroxypropyltrimethylammonium chloride chitosan: Weigh 4.83 g chitosan and disperse it in 30mL isopropanol to swell at room temperature, add 2,3-epoxypropyltrimethylammonium chloride 19.32 g, reacted at 55-65°C for 12 hours; then added 70mL of methanol for alcohol precipitation, the resulting precipitate was washed with 85% ethanol and suction filtered to obtain a filter cake, and dried to constant weight to obtain hydroxypropyltrimethyl chloride ammonium chitosan;

[0046] 2) Preparation of hydroxypropyltrimethylammonium chloride chitosan-carboxymethyl inulin salt: 3.42 g of hydroxypropyltrimethylammonium chloride chitosan obtained above was dissolved in 30 mL deionized water, and weighed Take 3.73 g carboxymethyl inulin and dissolve it in 37 mL of deionized water, then slowly add carboxymethyl inulin aqueous solution to the former, react at room temperature for 18 hours, then transfer the mixed solution to...

Embodiment 3

[0048] The difference from Example 1 is:

[0049] 1) Preparation of hydroxypropyltrimethylammonium chloride chitosan: Weigh 4.83 g chitosan and disperse it in 40mL isopropanol to swell at room temperature, add 2,3-epoxypropyltrimethylammonium chloride 24.15 g, reacted at 55-65°C for 12 hours; then added 80mL of methanol for alcohol precipitation, the resulting precipitate was washed with 85% ethanol and suction filtered to obtain a filter cake, and dried to constant weight to obtain hydroxypropyltrimethyl chloride ammonium chitosan;

[0050] 2) Preparation of hydroxypropyltrimethylammonium chloride chitosan-hyaluronic acid sodium salt: Dissolve 3.42 g of hydroxypropyltrimethylammonium chloride chitosan obtained above in 40 mL of deionized water, and then weigh 4.08 g of sodium hyaluronate was dissolved in 27 mL of deionized water, and then the sodium hyaluronate aqueous solution was slowly added dropwise to the former at room temperature to react for 24 hours, and then the mi...

Description

technical field [0001] The invention relates to food and biomedicine industries, in particular to a hydroxypropyltrimethylammonium chloride chitosan-carboxypolysaccharide compound salt and a preparation method and application thereof. Background technique [0002] Hygroscopic humectants are a class of hygroscopic compounds that can absorb moisture from humid air, and achieve moisturizing, moisturizing and other effects by absorbing and retaining moisture. Hygroscopic moisturizers are mainly used in food and daily chemical fields. Moisturizer is an indispensable and important ingredient in cosmetics. Hyaluronic acid derived from organisms is an excellent moisturizer. It is used in high-end cosmetics to make the skin elastic and smooth, and delay skin aging. However, its raw materials are limited, the preparation process is complicated, and the cost is high, which restricts the wide application of hyaluronic acid. For this reason, people continue to research and develop the ...
