Lyophilized collagen mask and preparation method thereof

Abstract

The invention provides a lyophilized collagen mask. The lyophilized collagen mask is prepared from recombinant human-derived collagen, sodium hyaluronate, betaine, hydroxyethyl cellulose, a first nutrient, a second nutrient, a third nutrient, a lyophilizing adjuvant and deionized water. By reasonably proportioning collagen, nutrient substances and other components, the lyophilized collagen refreshing mask which is convenient to store, not easy to deteriorate, high in activity and easy to use can be prepared and can be used immediately after being dissolved, so that the safety of the raw materials can be kept, and the use convenience is improved. Hydroxyethylurea, tetrahydromethylpyrimidine carboxylic acid and nicotinamide are added into the formula, so that the stable state of human skin can be maintained, the epidermal repair speed is accelerated, and wound healing is promoted. Compared with the formula in the prior art, the product has the advantages of high safety, low irritation risk, rich composition, high effectiveness, high security, high bioactivity, good moisturizing effect, human body absorption improvement, epidermal repair speed acceleration and wound healing promotion.

Description

technical field [0001] The invention belongs to the technical field of medical supplies, and in particular relates to a freeze-dried collagen facial mask and a preparation method thereof. Background technique [0002] The common form of collagen mask is usually made in a wet method. The non-woven or elastic mask paper is soaked in the essence with beauty ingredients, and then sealed and packaged into a small package that can be carried around. When using it, take out the mask that is full of essence. Apply to face. However, the preservation of wet facial masks is not easy. Since the ingredients of the essence are mostly high-nutrient substances, the humid environment with high water activity can easily promote the growth of bacteria or mold. The storage period is short, and antimicrobial agents such as parabens must be added. Preserved with high-grade preservatives, it is easy to cause allergies, and then cause the suspicion of contact dermatitis, causing damage to users. ...

Problems solved by technology

However, the preservation of wet facial masks is not easy. Since the ingredients of the essence are mostly high-nutrient substances, the humid environment with high water activity can easily promote the growth of bacteria or mold. The storage period is short, and antimicrobial agents such as parabens must be added. Preserved with preservatives, it is easy to cause allergies, and then cause contact dermatitis, causing damage to users

[0003] In addition, most of the collagen used in existing facial masks is animal collagen, which has hidden dangers of immune response and virus. It needs to be transported and stored in a cold chain, otherwise it will lose its activity due to variability, and the activity of collagen after production is unstable. Many raw materials with high biological activity are used in facial masks. Systems with high water activity will attenuate and deteriorate easily, which is not conducive to preservation and exert its biological effects, and the preservation period is short and the preservation conditions are harsh

If the existing commercial formula is to be sterile, the product needs to be irradiated with Co 60, but irradiation will cause structural changes in some components, thereby losing their activity

The ingredients of the formula are relatively single, and other ingredients that help skin repair but are not resistant to radiation cannot be compounded
