Problems solved by technology

[0004] Chitosan is non-toxic, tasteless, and has antibacterial effect. When it is mixed into cosmetics, it can improve the film-forming property of the product, and has antibacterial and moisturizing functions; however, chitosan has poor solubility in water, and it needs to adjust the medium when using it. It is acidic, which limits the application range of chitosan in daily chemicals

preparation example Construction

[0025] The preparation step of described quaternary ammonium salt modified chitosan comprises:

[0026] Weigh chitosan and dissolve in acetic acid, stir at 25-35°C for 1.5-2.5 hours; continue to cool down to 0-5°C, then add cyanuric chloride and tetrahydrofuran, stir and react for 6-10 hours; Raise the temperature to 25-35°C, add quaternary ammonium salt, and stir for 8-12 hours; separate the solid from the liquid, wash the solid product with deionized water for 5 times, and then vacuum dry the solid product at 60-90°C for 12-24 hours Hours, quaternary ammonium salt modified chitosan was obtained.

[0027] The mass ratio of cyanuric chloride to chitosan is (0.5-2):1, and the mass ratio of quaternary ammonium salt to chitosan is (1-2):1.

[0028] Further preferably, the quaternary ammonium salt is 2,3-epoxypropyltrimethylammonium chloride and (2,3-epoxypropyl) ethyl bis (2-hydroxyethyl) ammonium chloride, 2, The weight ratio of 3-epoxypropyltrimethylammonium chloride to (2,3-...

Embodiment 1

[0051] This embodiment provides a functional facial mask containing medical ingredients. In parts by weight, its raw materials include 2 parts of chitosan, 10 parts of gelatin, 3 parts of collagen, 6 parts of glycerin, 0.3 parts of allantoin, lemon 1 part acid, 56 parts deionized water.

[0052] The chitosan is quaternary ammonium salt modified chitosan. The preparation step of quaternary ammonium salt modified chitosan comprises:

[0053] Weigh chitosan and dissolve it in acetic acid, stir at 30°C for 2 hours; continue to cool down to 0°C, then add cyanuric chloride and tetrahydrofuran, stir and react for 8 hours; raise the temperature of the reaction system to 30°C, add quaternary ammonium salt, stirred and reacted for 8 hours; the obtained product was separated from solid and liquid, and the solid product was washed 5 times with deionized water, and then the solid product was vacuum-dried at 85° C. for 20 hours to obtain quaternary ammonium salt modified chitosan.

Abstract

The invention relates to the field of cosmetics, in particular to a functional mask containing medical components and a preparation method thereof. The functional mask is prepared from, by weight, 1-5parts of chitosan, 5-25 parts of gelatin, 0.5-15 parts of collagen, 4-10 parts of glycerol, 0.1-0.5 part of allantoin, 0.8-1.6 parts of citric acid and 50-82 parts of deionized water. The antibacterial functional mask with an efficient and lasting moisturizing effect is prepared according to the formula, and the mask has the effects of rapidly moisturizing the skin and promoting absorption, can maintain the skin moist for a long time and relieve the tight and dry itching state of the skin, is mild and free of irritation, and brings excellent sensory experience; and meanwhile, the mask is simple in preparation process and high in practicability, and has a wide application prospect.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a functional mask containing medical ingredients and a preparation method thereof. Background technique [0002] Chitosan is the product of natural polysaccharide chitin by removing part of the acetyl group. It has various physiological functions such as biodegradability, biocompatibility, non-toxicity, antibacterial, anticancer, lipid-lowering, and immune enhancement. It is widely used in food Additives, textiles, agriculture, environmental protection, beauty care, cosmetics, antibacterial agents, medical fibers, medical dressings, artificial tissue materials, drug sustained-release materials, gene transduction carriers, biomedical fields, medical absorbable materials, tissue engineering carrier materials, Many fields such as medical treatment and drug development and other daily chemical industries. The solubility of chitosan is related to the degree of deacetylation, relative molecul...
