Description

Technical Field

[0001] This invention relates to the field of facial mask preparation technology, and in particular to a preparation process for a natural ingredient composite acne-removing collagen facial mask. Background Technology

[0002] Acne is a chronic inflammatory disease of the hair follicles and sebaceous glands. Most existing acne treatments contain chemical antibacterial agents (such as benzoyl peroxide), which can easily lead to skin irritation and barrier damage. Collagen has repairing effects, but a single ingredient cannot simultaneously address the needs for antibacterial, oil control, and soothing. Chitosan derivatives (such as carboxymethyl chitosan) have natural antibacterial properties, but their solubility and stability are poor. Therefore, developing an acne-reducing mask that combines natural ingredients for synergistic effects has significant market value. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a preparation process for a natural ingredient composite acne-removing collagen facial mask. The composite acne-removing collagen facial mask prepared using the present invention exhibits consistent product performance and excellent repair and acne-removing effects.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A preparation process for a natural ingredient complex acne-removing collagen facial mask includes the following specific steps:

[0006] S1. Dissolve recombinant collagen in deionized water to obtain a base solution; then add moisturizer, hydroxymethyl chitosan, medical preservative, and peppermint flavor to the base solution and stir well; then add triethanolamine to adjust the pH of the mixture, and finally add carbomer to adjust the viscosity of the mixture to obtain a skin care lotion for later use.

[0007] S2. Fold the non-woven fabric mask sheet and place it into the mask bag. At the same time, add the skin care essence into the mask bag, seal the mask bag, and then refrigerate it.

[0008] The recombinant collagen in this invention plays a repairing and regenerating role, promoting skin wound healing. Hydroxymethyl chitosan has antibacterial and anti-inflammatory effects. The moisturizer provides a humid environment for the face. The peppermint fragrance, extracted from peppermint, helps clear acne, relieve itching, and provides a cooling sensation in summer. This invention combines these four ingredients to synergistically exert antibacterial, anti-inflammatory, acne-reducing, and moisturizing effects. It also provides a comfortable, skin-adhering feel, and is not sticky or stuffy in summer. Specifically, the combined use of recombinant collagen and hydroxymethyl chitosan enhances the activity and stability of the recombinant collagen, thereby accelerating skin cell metabolism and aiding in tissue repair at the site of acne scars.

[0009] Preferably, the skin care lotion comprises the following ingredients by weight percentage: 0.05-3.0% recombinant collagen, 0.1-1.5% hydroxymethyl chitosan, 3-15% moisturizer, 0.1-0.6% medical preservative, 0.01-0.05% peppermint fragrance, 0.04-0.20% triethanolamine, 0.1-0.8% carbomer, with the balance being deionized water.

[0010] The above-shown range of raw material component proportions can be any of the specified precise digits in actual application.

[0011] For example, "recombinant collagen 0.5-3.0%" means that the weight percentage of recombinant collagen can be 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1.0%, 1.1%, 1.2%, 1.3%, 1.4%, 1.5%, 1.6%, 1.7%, 1.8%, 1.9%, 2.0%, 2.1%, 2.2%, 2.3%, 2.4%, 2.5%, 2.6%, 2.7%, 2.8%, 2.9%, or 3.0%, etc.

[0012] The phrase "5-15% humectant" refers to the fact that the weight percentage of the humectant can be 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, or 15%, etc.

[0013] The phrase "0.02-0.05% peppermint flavoring" refers to the fact that the weight percentage of peppermint flavoring can be 0.02%, 0.03%, 0.04%, or 0.05%.

[0014] This allows us to extrapolate the possible values ​​of other components in practical applications.

[0015] Preferably, the moisturizer is a combination of glycerin and propylene glycol, wherein the weight percentage of glycerin is 2-10% and the weight percentage of propylene glycol is 1-5%. In this invention, both glycerin and propylene glycol play a moisturizing and lubricating role, but excessive use of either can irritate the skin, causing stinging and redness. For acne-prone skin, the synergistic effect of glycerin and propylene glycol can enhance the absorption of recombinant collagen, hydroxymethyl chitosan and peppermint fragrance, thereby increasing the acne-removing effect.

[0016] Preferably, the medical preservative is either methylparaben or ethylparaben, or a combination thereof, both of which have excellent antibacterial effects.

[0017] Preferably, the refrigeration temperature is 4-8℃.

[0018] Preferably, after adding triethanolamine, the pH value of the mixture is adjusted to 5.0-7.0. The mixture can inhibit the reproduction of acne bacteria and achieve a stabilizing effect on acne.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] In this invention, recombinant collagen promotes skin wound healing, hydroxymethyl chitosan has antibacterial and anti-inflammatory effects, peppermint flavor clears skin acne and provides a cooling sensation, and moisturizers enhance penetration. All components work synergistically to exert antibacterial, anti-inflammatory, moisturizing, and acne-reducing effects, while also providing an excellent user experience. Furthermore, the preparation process provided by this invention is simple to operate, low in cost, and easy to scale up for industrial production. Detailed Implementation
