Description

Technical Field

[0001] The present application relates to the technical field of skin care products, and in particular to a water-oil dual-compartment facial mask liquid and a preparation method and application thereof. Background Art

[0002] As consumers' demands for skin care products continue to change, the facial mask market is also developing. Among them, the antioxidant property of facial masks is a focus of attention. Facial masks usually contain a variety of ingredients, such as water, moisturizers, active ingredients, preservatives, etc. The effects of facial masks are diverse, including hydration, whitening and lightening, firming and lifting, etc.

[0003] Astaxanthin is a commonly used ingredient in facial masks. It belongs to the carotenoid class and has some of the same biosynthetic pathways as beta-carotene. They both have polyene chains that can quench free radicals. Astaxanthin is part of the lutein subgroup because its additional keto and hydroxyl groups are attached to the isoprene ring. This gives astaxanthin the ability to optimally locate hydrophilic and hydrophobic positions and provide excellent antioxidant protection for the lipid bilayer.

[0004] However, astaxanthin is easily oxidized when exposed to water during use, easily decomposed when exposed to light, loses its activity, and has poor stability, which greatly limits the application of astaxanthin.

[0005] Therefore, there is an urgent need for a method to improve the antioxidant activity and stability of facial masks containing astaxanthin. Summary of the invention

[0006] In order to solve the above technical problems, the present application provides a water-oil dual-compartment facial mask liquid and a preparation method and application thereof.

[0007] The present application provides a water-oil dual-compartment facial mask liquid, which is composed of an oil phase and a water phase in a weight ratio of 0.8-1.2:10; The oil phase comprises the following components in parts by weight: 86-116 parts of an emollient, 0.001-0.05 parts of astaxanthin, 0.05-0.5 parts of tocopherol, and 0.005-0.02 parts of a stabilizer; the stabilizer is composed of a mixture of chestnut peptide and disodium dihydrogen pyrophosphate in a weight ratio of 1:0.05-0.15; The aqueous phase comprises the following components in parts by weight: 80-95 parts of water, 0.05-0.25 parts of hydroxyethyl cellulose, 0.2-0.8 parts of sea cucumber extract, 0.01-0.3 parts of acrylic acid (ester) / C10-30 alkyl acrylate cross-linked polymer, 2.5-15.5 parts of moisturizer, 0.55-2.2 parts of anti-inflammatory and antibacterial agent, and 1.5-3.5 parts of 0.1-0.3wt% carnosine aqueous solution; The viscosity of the hydroxyethyl cellulose is 1500-2500 mpa.s; The preparation method of the sea cucumber extract comprises the following steps: evenly mixing 90-110 parts by weight of cleaned sea cucumbers and 1000 parts by weight of water, crushing the mixture, stirring the mixture evenly, adding 0.4-0.7 parts by weight of papain and 0.8-1.1 parts by weight of flavor protease into the slurry, stirring the mixture evenly, performing enzymolysis at a temperature of 38-42° C. for 40-80 minutes, filtering the mixture to obtain a filtrate, and concentrating and sterilizing the mixture to obtain the sea cucumber extract.

[0008] As a powerful antioxidant, astaxanthin can neutralize free radicals and reduce UV damage to the skin. In addition, astaxanthin helps improve skin elasticity, reduce the appearance of fine lines and wrinkles, and make the skin smoother and more delicate.

[0009] The present application adopts a compartment form, placing astaxanthin in combination with a moisturizer and tocopherol into the oil phase compartment, and at the same time placing a water-soluble component containing a specific amount of hydroxyethyl cellulose and sea cucumber extract into the water phase compartment. On the one hand, the contact between the oil phase and the water phase is avoided, which not only avoids the contact between astaxanthin and water, but also improves the antioxidant and stability of the facial mask liquid. On the other hand, a specific amount of astaxanthin combined with a moisturizer and tocopherol can effectively improve the antioxidant and stability of the facial mask liquid; and the facial mask liquid provided by the present application is beneficial to enhancing the moisture content of the skin.

[0010] In the technical solution of the present application, the chestnut peptide in the stabilizer is rich in bioactive ingredients, which can promote the regeneration and repair of skin cells, and has obvious effects on reducing skin damage and improving skin texture; its bioactive ingredients also help to resist the retention of free radicals in the mask liquid and improve its stability. The disodium dihydrogen pyrophosphate in the stabilizer is used in combination with the chestnut peptide, which has the effect of promoting the penetration of effective ingredients, can enhance the antioxidant effect, and resist the damage of free radicals; at the same time, it can improve the utilization rate of the chestnut peptide component, thereby further enhancing the stability effect of the mask liquid. During the experiment, the inventor found that the dosage ratio between chestnut peptide and disodium dihydrogen pyrophosphate and the dosage of the two mixed as a stabilizer in the oil phase have a great influence on the stability of the mask liquid. After many experiments, the optimal ratio was determined, thereby further enhancing the stability of the mask liquid.

[0011] In the technical solution of the present application, the olefinic acid (ester) / C10-30 alkyl acrylate cross-linked polymer in the aqueous phase can increase the viscosity density and stability of the product, and serve as an emulsion stabilizer, thickener and suspending agent. Carnosine has a strong antioxidant capacity, can remove free radicals in the body, and reduce the damage to the skin caused by oxidative stress; carnosine also has an anti-glycation effect, and can compete with sugars in the body to bind to proteins, thereby reducing the generation of glycation end products, protecting the skin's collagen and elastin from being destroyed by glycation, and maintaining the skin's elasticity and luster. Hydroxyethyl cellulose, as a high-quality water-soluble polymer, has excellent water-retaining properties.

[0012] Sea cucumber extract is designed by combining effective ingredients with other raw materials. The protein in sea cucumber can effectively improve skin sagging and fine lines, improve skin elasticity and firmness; and has a good moisturizing effect, can lock skin moisture and enhance the skin's barrier function; the saponin in sea cucumber has a certain antioxidant effect. In the process of preparing sea cucumber extract, the applicant found that when the content of sea cucumber polysaccharides is high or the content of sea cucumber saponins is low, the antioxidant stability of the mask liquid is extremely poor. Therefore, the effective ingredients in the sea cucumber extract provided by this application are controlled as follows: the weight content of protein is 22-28%, the weight content of sea cucumber polysaccharides is 1.9-2.5%, and the weight content of sea cucumber saponins is 0.09-0.15%.

[0013] The present application adds a suitable amount of olefinic acid (ester) / C10-30 alkyl acrylate cross-linked polymer and carnosine aqueous solution, sea cucumber extract, and hydroxyethyl cellulose of suitable viscosity to the aqueous phase of the facial mask liquid. When the aqueous phase and the oil phase are in contact during use of the facial mask, various active ingredients can be more fully integrated, which is beneficial to improving the antioxidant properties of the oil phase and the aqueous phase after mixing, effectively resisting the invasion of free radicals, delaying skin aging, and increasing the elasticity and glossiness of the skin; at the same time, it can help the skin resist the oxidative stress in the external environment; it also has good moisturizing properties, penetrates deep into the skin, locks in moisture, and provides a lasting moisturizing effect for the skin.

[0014] Preferably, the oil phase comprises the following components in parts by weight: 96-126 parts of emollient, 0.01-0.03 parts of astaxanthin, 0.1-0.3 parts of tocopherol, and 0.01-0.015 parts of stabilizer; the stabilizer is composed of a mixture of chestnut peptide and disodium dihydrogen pyrophosphate in a weight ratio of 1:0.08-0.12.

[0015] Preferably, the aqueous phase comprises the following components in parts by weight: 84-90 parts of water, 0.1-0.2 parts of hydroxyethyl cellulose, 0.4-0.6 parts of sea cucumber extract, 0.1-0.2 parts of acrylic acid (esters) / C10-30 alkyl acrylate cross-linked polymer, 5-10 parts of moisturizer, 1-1.5 parts of anti-inflammatory and antibacterial agent, and 2-3 parts of 0.1-0.3wt% carnosine aqueous solution.

[0016] Preferably, in the sea cucumber extract: the weight content of protein is 22-28%, the weight content of sea cucumber polysaccharide is 1.9-2.5%, and the weight content of sea cucumber saponin is 0.12-0.20%.

[0017] Furthermore, in the sea cucumber extract: the weight content of protein is 24-26%, the weight content of sea cucumber polysaccharide is 2.1-2.3%, and the weight content of sea cucumber saponin is 0.11-0.13%.

[0018] Preferably, the emollient is composed of a mixture of cetyl ethylhexanoate, squalane, jojoba seed oil, sorbitan polyether-30 tetraisostearate, and polyglyceryl-6 dicaprate in a weight ratio of 80-90:1-5:1-5:2-8:2-8.

[0019] Cetyl ethylhexanoate is a highly effective, waterproof, high-performance emollient that is miscible with oils and fats. It has the advantages of good air permeability, spreadability, dispersibility and moisturizing properties. After use, it can give the skin a moisturized, soft, non-greasy and pleasant skin feel. Squalane is a colorless, transparent oily liquid with good moisturizing and humectant properties. When added to cosmetics, it can help the skin stay hydrated, enhance the skin's barrier function, reduce water loss, and help improve skin dryness, roughness, peeling and other problems. In addition, squalane also has good permeability and spreadability, and can form a protective film on the skin surface to repair and moisturize the skin. Jojoba seed oil is mainly composed of long-chain monounsaturated hydrocarbons and a small amount of diunsaturated hydrocarbons. This ingredient makes it very similar to the sebum secreted by human skin, so it has good compatibility; jojoba seed oil can penetrate deep into the skin, provide moisture and hydration to the skin, while not leaving a greasy feeling; it also helps balance the skin's oil secretion. Sorbitol polyether-30 tetraisostearate is a nonionic surfactant, mainly used in cosmetics and personal care products. It has good emulsifying and dispersing properties, which can improve the stability and feel of the product. Polyglyceryl-6 dicaprate has excellent moisturizing and hydrating effects, which can help the skin retain moisture, provide a soft touch, and enhance the ductility and stability of the product.

[0020] The present application reasonably optimizes the ratio of the raw material components in the emollient, so that the prepared facial mask liquid has stronger antioxidant stability.

[0021] Preferably, the moisturizing agent is composed of a mixture of butylene glycol, glycerol, sodium hyaluronate and hydrolyzed sclerotium gum in a weight ratio of 1-10:1-5:0.03-0.3:0.05-0.2.

[0022] Butylene glycol and glycerin are often used as moisturizers in cosmetics to help the skin retain moisture, making the skin look fuller and smoother. In addition, butylene glycol can also help penetrate the stratum corneum on the surface of the skin and carry water-soluble small molecules into the skin to achieve better moisturizing effects. Sodium hyaluronate has good water retention properties and can effectively retain the moisture of the skin, keeping the skin moist and elastic, achieving anti-aging and beauty effects; sodium hyaluronate can also improve skin dryness and sagging wrinkles, soften the skin, increase luster, and provide comprehensive elastic repair and nourishment protection for the skin. Hydrolyzed sclerotium gum is a natural high-molecular moisturizing ingredient with good water retention, film-forming properties and stability.

[0023] Preferably, the anti-inflammatory and antibacterial agent is composed of a mixture of dipotassium glycyrrhizinate, 1,2-hexanediol and p-hydroxyacetophenone in a weight ratio of 0.05-0.2:0.3-1:0.2-1.

[0024] Dipotassium glycyrrhizinate is used as a skin conditioner to soothe and fight inflammation. 1,2-Hexanediol has excellent moisturizing and antibacterial properties, which can help cosmetics maintain product quality and has a certain preservative effect. Parahydroxyacetophenone has antioxidant and antibacterial properties, which can ensure the quality and safety of cosmetics and extend their service life.

[0025] In a second aspect, the present application provides a method for preparing the above-mentioned water-oil dual-compartment facial mask liquid, which specifically comprises the following steps: Put the raw materials of each component of the emollient into a vacuum emulsification tank according to the proportion, stir evenly, and add a stabilizer; then mix astaxanthin and tocopherol evenly, put them into the tank, stir until they are completely dissolved, and obtain an oil phase; Put acrylic acid (ester) / C10-30 alkyl acrylate cross-linked polymer, hydroxyethyl cellulose and sea cucumber extract into water and stir evenly; then add moisturizer and anti-inflammatory and antibacterial agent in turn, stir and heat to 75-85°C to dissolve, then cool to 40-45°C; then add carnosine aqueous solution, stir evenly, cool to 20-35°C to obtain a water phase.

[0026] In a third aspect, the present application provides a water-oil dual-compartment facial mask, which is prepared from a facial mask cloth and the above-mentioned water-oil dual-compartment facial mask liquid.

[0027] This application adopts the packaging form of ready-to-mix and ready-to-use (such as Figure 1 Astaxanthin can better exert its efficacy; when using, mix the oil phase and the water phase, shake well to emulsify, and apply to the face. The astaxanthin membrane cloth used in the mask cloth is made by mixing astaxanthin with natural fibers, combing, laying nets, water-spun reinforcement, and drying; thus, the membrane cloth also has certain antioxidant effects; the combination of the two has a synergistic effect.

[0028] In summary, the technical solution of this application has the following effects: The present application adopts a compartment form, placing astaxanthin, moisturizer and tocopherol into the oil phase compartment, and at the same time placing a water-soluble component containing a specific amount of hydroxyethyl cellulose and sea cucumber extract into the water phase compartment. This not only avoids the contact between astaxanthin and water, improves the antioxidant stability of the mask liquid, but also the mask liquid provided by the present application is beneficial to enhancing the moisture content of the skin.

[0082] Table 2 Performance test results of water-oil dual compartment facial mask liquid in examples and comparative examples Combined with the test results in Table 2, it can be seen that: in Comparative Example 1, no stabilizer was added to the oil phase, and the stability and water retention performance of the facial mask liquid were poor. In Comparative Example 2, no sea cucumber extract was added to the water phase, and the antioxidant, stability and water retention properties of the facial mask liquid were poor. In Comparative Example 3, the amount of stabilizer and sea cucumber extract did not match, and the antioxidant and stability properties of the facial mask liquid were poor. The preparation methods of sea cucumber extracts in Comparative Examples 4-7 did not match, and the antioxidant and stability properties of the facial mask liquid were poor; the reason for the analysis may be that the content of effective ingredients in the sea cucumber extracts did not match. The types of stabilizers in Comparative Examples 8-9 did not match, and the stability of the facial mask liquid was poor. The viscosity of hydroxyethyl cellulose in Comparative Example 10 did not meet the technical solution, and the stability and water retention properties of the prepared facial mask liquid were poor.

[0083] In contrast, the technical solution of the embodiment of the present application utilizes a mixture of chestnut peptide and disodium dihydrogen pyrophosphate in a weight ratio of 1:0.05-0.15 to form a stabilizer in the oil phase, and astaxanthin is placed in the oil phase compartment with an emollient, tocopherol, and a stabilizer. At the same time, a specific amount of hydroxyethyl cellulose, sea cucumber extract and other effective ingredients are placed in the water phase compartment, which not only avoids the contact between astaxanthin and water, but also improves the antioxidant and stability of the mask liquid; at the same time, the mask liquid provided by the present application is beneficial to enhancing the moisture content of the skin.

[0084] Although the present invention has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements may be made thereto based on the present invention.
