Problems solved by technology

At present, the beauty and skin care masks on the market are basically made of chemical synthetic fiber non-woven fabrics or man-made fiber non-woven fabrics through folding, bagging, injection of soaking liquid, sealing and other processes. It has a certain beauty and skin care effect, but there are also shortcomings, such as: there is a degradation problem, and it cannot be recycled; long-term immersion in the soaking solution will cause the fibers and adhesives of the non-woven fabric to partially dissolve, reducing the use of the mask. Effect, and It is easy to cause allergies to consumers; the use of polymer synthetic resin as a thickener will make consumers feel tight after use

preparation example Construction

[0026] The invention provides a preparation method of whitening and moisturizing alginate facial mask, which comprises the following steps:

[0027] S1: Synthesis of alginic acid chloride: Dispersing and dissolving alginic acid powder in CCl 4 Solution, obtain alginic acid solution, add PCl dropwise in described alginic acid solution 3 , control the temperature at 50-55°C, react for 4-8 hours, then raise the temperature to 60-70°C, and react for 1-1.5 hours to obtain alginate chloride;

[0028] S2: Synthesis of ternary compound alginate: disperse and dissolve octacosanol, kojic acid, and arbutin in a solvent to obtain a mixed solution, add dropwise the alginic acid chloride prepared in step S1 to the mixed solution, and store at room temperature The following reaction, to get ternary compound alginate;

[0029] S3: Preparation of alginate mask: completely dissolve the ternary compound alginate prepared in step S2 in acetone solution, stir evenly to obtain a spinning solution...

Embodiment 1

[0043] S1: The alginic acid powder is subjected to plasma treatment, the conditions are: the gas uses oxygen, the treatment power is 280W, the pressure is 55Pa, and the treatment time is 12min; 1.5g of the plasma-treated alginic acid powder is added to the three-necked flask, and 100ml of CCl 4 Dispersed and dissolved, 12g PCl 3 Use a dropping funnel to slowly drop into a three-necked flask, the reaction temperature is 55°C, the reaction time is 6h, then the temperature is raised to 60°C, and the reaction is continued for 1h, and the reaction is stopped to obtain alginate chloride;

[0044] S2: Add 0.8g of octacosanol, 0.4g of kojic acid, and 0.2g of arbutin into a three-necked flask, disperse and dissolve them with 40ml of acetone and 8ml of pyridine solution, and then slowly drop 15ml of alginate chloride into In a three-necked flask, react at room temperature. After reacting for 4 hours, the product obtained by the reaction was washed with an appropriate amount of ice etha...

Embodiment 2

[0047] S1: The alginic acid powder is subjected to plasma treatment, the conditions are: the gas is nitrogen, the treatment power is 250W, the pressure is 50Pa, and the treatment time is 10min; 4 Dispersed and dissolved, 2.5g PCl 3 Use a dropping funnel to slowly drop into a three-necked flask, the reaction temperature is 55°C, the reaction time is 4h, then the temperature is raised to 60°C, and the reaction is continued for 1h, and the reaction is stopped to obtain seaweed chloride;

[0048] S2: Add 0.5g of octacosanol, 0.2g of kojic acid, and 0.1g of arbutin into a three-necked flask, disperse and dissolve it with 20ml of acetone and 5ml of pyridine solution, and then slowly drop 8ml of alginate chloride into it with a dropping funnel In a three-necked flask, react at room temperature. After reacting for 2 hours, the product was washed with an appropriate amount of ice ethanol, suction-filtered on a Buchner funnel, washed repeatedly for at least 3 times, and dried to obtain...

Abstract

The invention discloses a preparation method of a whitening and moisturizing alginate facial mask. The preparation method comprises the following steps of (1) carrying out plasma treatment on alginicacid, and carrying out acylating chlorination to obtain acyl chloride alginate; (2) carrying out esterification grafting reaction on octacosanol, kojic acid, arbutin and the acyl chloride alginate toobtain octacosanol, kojic acid and arbutin mixed ester (ternary composite alginate) of the alginic acid; (3) completely dissolving the ternary composite alginate in a 10% ammonia water solution, and carrying out uniform stirring to obtain a spinning solution; and (4) carrying out electrostatic spinning by adopting the spinning solution to obtain the ternary composite alginate facial mask. Preparednanofibers have efficient whitening and moisturizing activation effects on the skin.

Description

technical field [0001] The invention relates to the fields of biochemical industry and cosmetics, in particular to a whitening and moisturizing alginate mask and a preparation method thereof. Background technique [0002] Mask is a carrier of beauty care products. When the mask is applied on the face, the moisture and nutrients in the mask can tighten the skin, allowing the water to fully penetrate into the stratum corneum of the skin epidermis. At the same time, the nutritional or functional substances It will fully penetrate into the deep layer of the skin, soften the skin, enhance skin elasticity, promote capillary expansion, remove dust, chemical pollutants, bacteria and grease from pores, accelerate blood microcirculation in deep skin, and enhance the vitality of cells in each layer of the epidermis. Eliminate skin fatigue, aging, and maintain youthfulness. At present, the beauty and skin care masks on the market are basically made of chemical synthetic fiber non-woven...
