Embodiment 1

[0027] Weigh 100 parts of dry collagen product and add it to 900 parts of water. After swelling at room temperature for 50 minutes, place it in a water bath at about 60°C and keep stirring for about 40 minutes to obtain a collagen solution with a mass fraction of about 10%. At the same time, 10 parts of caffeic acid were weighed and added to 990 parts of water, and stirred continuously at about 20° C. for about 12 hours to obtain a caffeic acid solution with a mass fraction of about 1%. At 50°C, blend according to the ratio of collagen to caffeic acid dry weight of 1000:1, use sodium carbonate and acetic acid solution to adjust the pH to 8, and add an appropriate amount of water to stir continuously for about 30 minutes to obtain the concentration of collagen About 5% caffeic acid-collagen complex solution by weight of dry product. Weigh 10 parts of auxiliary additives (blended according to the ratio of 1:1 dry weight ratio of propylene glycol and xylitol) to 990 parts of wate...

Embodiment 2

[0029] Weigh 20 parts of dry collagen and add it to 980 parts of water. After swelling at room temperature for 20 minutes, place it in a water bath at about 40°C and stir continuously for about 20 minutes to obtain a collagen solution with a mass fraction of about 2%. At the same time, weigh 5 parts of phenolic acids (blended according to the ratio of ferulic acid to isoferulic acid in a dry weight ratio of 2:1) and add them to 995 parts of water, and stir continuously at about 30°C for about 6 hours to obtain the mass fraction About 0.5% aqueous solution of phenolic acids. At 50°C, the dry weight ratio of collagen and phenolic acids was blended at 1000:1, the pH was adjusted to 8.5 with sodium carbonate and acetic acid solution, and an appropriate amount of water was added and stirred continuously for about 40 minutes to obtain a concentration of Collagen dry product weight meter is about 1% phenolic acid-collagen complex solution. Weigh 10 parts of xanthan gum and add it to...

Embodiment 3

[0031]Weigh 60 parts of dry collagen and add to 940 parts of water, swell at room temperature for 30 minutes, place in a water bath at about 30°C and stir continuously for about 40 minutes to obtain a collagen solution with a mass fraction of about 6%. At the same time, weigh 4 parts of phenolic acids (2 parts of catechin, 1 part of salicylic acid, and 1 part of gallic acid) and add them to 996 parts of water, and stir continuously at about 30°C for about 9 hours to obtain a mass fraction of about 0.4%. Aqueous solutions of phenolic acids. At 50°C, the dry weight ratio of collagen and phenolic acids was blended at 1500:1, the pH was adjusted to 7 with sodium carbonate and acetic acid solution, and an appropriate amount of water was added and stirred continuously for about 40 minutes to obtain a concentration of Collagen dry product weight meter is about 3% phenolic acid-collagen complex solution. Weigh 10 parts of auxiliary additives (6 parts of glycerin, 1 part of mannitol, ...

Abstract

The invention provides a phenolic acid modified collagen mask and a preparation method thereof. The method comprises the following steps of: firstly, mixing and stirring a collagen water solution (1-30% in mass fraction) and a phenolic acids water solution (0.1-3% in mass fraction) under the pH of 5-10 at the temperature of 20-60 DEG C for 20-60 minutes; then adding an auxiliary additive water solution (1-20% in mass fraction), continuously stirring at the temperature of 20-60 DEG C for 20-40 minutes; and pouring the mixed solution into a mold for forming, and drying at the temperature of 20-50 DEG C for 6-24 hours to obtain the collagen mask. The collagen mask product prepared in the invention is safe and effective without toxic side effects, has good thermal stability, toughness, ductility and adhesiveness, can be well applied to skin, and can play the efficacies of resisting wrinkles, whitening, moistening, cleaning and nourishing skin and the like by the aid of the phenolic acids; and the mask waste is degradable without causing environmental pollution.

Description

technical field [0001] The invention relates to beauty cosmetics and preparation technology thereof, in particular to a phenolic acid modified collagen facial mask and a preparation method thereof, belonging to the field of daily cosmetics. Background technique [0002] Humans have a long history of using facial masks as beauty tools, dating back to ancient Egypt and the Tang Dynasty in China. The facial mask is to apply a layer of dressings with different components on the face to block the contact between the skin and the air to achieve the purpose of beauty. When this layer of dressing is tightly attached to the skin, it will inhibit the secretion of sebum and the evaporation of sweat, making the temperature of the skin rise; when the temperature of the skin rises, it will promote blood circulation, so that the nutrients that penetrate into the skin will diffuse between cells. Deeper and wider. At the same time, the water that cannot evaporate on the skin surface will r...
