Description

Technical Field

[0001] The invention belongs to the technical field of cosmetic preparation, and in particular relates to a long-lasting hydrating film-forming liquid foundation and a preparation method thereof. Background Art

[0002] Liquid foundation, as one of the key categories of facial beauty cosmetics, is an emulsion-like product that combines powder with liquid foundation. It aims to even out skin tone and play a modifying and concealing role in the makeup process. Its form is mainly in the form of oil-in-water (O / W) or water-in-oil (W / O) powder.

[0003] With the continuous improvement of aesthetic standards, consumers have put forward more stringent requirements for the coverage, color performance, glossiness and long-lasting makeup effect of liquid foundation. In this context, various natural active extracts with distinctive characteristics are widely used in liquid foundation, injecting a new trend of advocating nature into the cosmetics market. These ingredients derived from nature, with their natural and pure properties, well meet the dual needs of modern consumers for health and environmental protection. The diverse biological activities of natural active extracts bring diversified effects to foundation products, covering from basic moisturizing and hydrating to advanced antioxidants, and then to anti-inflammatory and calming, whitening and spot removal, etc., which not only improves the health of the skin, but also significantly enhances the skin care effect of liquid foundation. At the same time, the mild characteristics of these ingredients and their good affinity with the physiological structure of the human body effectively reduce the risk of skin allergies and irritation, making foundation products safer and more reliable.

[0004] However, there are also a series of challenges when applying natural active extracts to liquid foundation: ① Natural active extracts often contain ingredients that are easily oxidized, which causes some plant extracts to oxidize prematurely after the liquid foundation is applied to the skin, affecting the durability of the liquid foundation.

[0005] ② The volatile components in the natural active extracts. During the preparation of the liquid foundation, the natural active extracts cannot be fully dissolved in the liquid foundation due to volatilization, resulting in waste, which reduces the utilization rate of the natural active extracts.

[0006] ③ After the liquid foundation is applied to the skin, due to volatilization, the content of effective natural active extracts that the skin can absorb is limited, thus limiting the use effect of the liquid foundation containing natural active extracts.

[0007] In order to make up for these deficiencies, a common strategy is to increase the content of natural active extracts in liquid foundation, but this approach also has many problems: ① Due to the high cost of natural active extracts, increasing their content will directly lead to an increase in the production cost of liquid foundation.

[0008] ② Liquid foundation has strict requirements on color and texture. Increasing the content of natural active extracts means that the content of other components needs to be reduced accordingly, which may have an adverse effect on the color and texture of the final liquid foundation product.

[0009] ③ After the liquid foundation is applied to the skin, the natural active extracts are more easily oxidized. The oxidized natural active extracts will be reduced in color, texture, and efficacy, resulting in significant changes in the color and texture of the liquid foundation. Especially when the content of natural active extracts increases, the content of oxidized ingredients increases, making the color and texture changes of the liquid foundation more obvious.

[0010] ④ Most natural active extracts have odor. Increasing the content of natural active extracts will cause the odor of the liquid foundation to become stronger, which can easily cause discomfort to consumers.

[0011] ⑤ Natural active extracts contain macromolecules and polyols. Macromolecules will increase the slipperiness of the liquid foundation, polyols will affect the drying speed of the film-forming agent, and macromolecules and polyols will reduce the speed of setting makeup.

[0012] There is also a practice in the market to extend the duration of natural active extracts by adding antioxidants to liquid foundation, but this practice also has the following disadvantages: ① Due to their high activity, antioxidants easily lose their activity when exposed to air, heat, light and alkaline substances, resulting in a short duration of antioxidant effect after the foundation is applied to the skin.

[0013] ② Antioxidants need to maintain good compatibility with other ingredients in liquid foundation (such as color powder, emulsifier, etc.). However, due to their high activity, antioxidants are prone to react with other ingredients in liquid foundation.

[0014] ③ In order to prevent antioxidants from oxidizing during storage, it may be necessary to use opaque packaging materials, which not only increases the cost of the product, but may also adversely affect the aesthetics and portability of the product.

[0015] ④ The use of antioxidants, especially those of natural origin, tends to increase the production cost of liquid foundation because these ingredients are usually more expensive. Summary of the invention

[0016] In view of the deficiencies in the prior art, the object of the present invention is to provide a long-lasting hydrating film-forming foundation liquid and a preparation method thereof.

[0017] In order to achieve the above-mentioned invention object, the technical solution adopted by the present invention includes: In one aspect, a long-lasting hydrating film-forming liquid foundation in the form of a water-in-oil type powder comprises: Grease, the grease comprising volatile silicone grease, diisostearyl malate, dipentaerythritol tri-polyhydroxystearate and polydimethylsiloxane; Film-forming agent A, the film-forming agent A is a silicone resin film-forming agent; Film-forming agent B, wherein the film-forming agent B comprises an organosilicon-modified polysaccharide film-forming agent, and the mass ratio of the film-forming agent B to the film-forming agent A is (1-30):100; The natural active extract has an antioxidant effect.

[0018] In the present invention, dipentaerythritol tri-polyhydroxystearate (DPT) has a molecular structure similar to the lipid structure of the skin, so it can be compatible with the lipids on the surface of the skin and reduce irritation to the skin; at the same time, dipentaerythritol tri-polyhydroxystearate has good stability and has a certain antioxidant capacity. In addition, since dipentaerythritol tri-polyhydroxystearate contains multiple hydroxyl groups in its molecular structure, dipentaerythritol tri-polyhydroxystearate can interact with polar components in natural active extracts, thereby having good solubility for natural active extracts.

[0019] Micelles are ordered, thermodynamically stable colloidal aggregates formed by self-assembly of molecules in aqueous solution. The micellar capacity of molecules can solubilize solutes and improve solute stability.

[0020] In the present invention, diisostearyl malate has two carbon chains, so that diisostearyl malate has a lower critical micelle concentration, which means that diisostearyl malate can form micelles at a lower concentration. The two carbon chains of diisostearyl malate enhance the association of diisostearyl malate with the natural active extract, thereby improving the solubility of diisostearyl malate with the natural active extract.

[0021] At the same time, diisostearyl malate has good chemical stability and is not easily oxidized. The micelles formed by diisostearyl malate have good chemical stability, which helps to maintain the stability of the natural active extracts encapsulated in the micelles and extend the shelf life of the product.

[0022] In the present invention, dipentaerythritol tri-polyhydroxystearate and diisostearyl malate have a synergistic effect after compounding. When dipentaerythritol tri-polyhydroxystearate and diisostearyl malate are compounded, as the proportion of diisostearyl malate increases, compounded micelles are easier to form and the solubilization effect is better. Therefore, the compounding of dipentaerythritol tri-polyhydroxystearate and diisostearyl malate can enhance the solubility of natural active extracts.

[0023] In the present invention, polydimethylsiloxane (PDMS) can form a protective film on the skin surface after film formation. This protective film can isolate oxygen and reduce the contact between the natural active extract and oxygen in the air, thereby reducing the possibility of oxidation reaction; at the same time, the silicon-oxygen bond in the molecular structure is very stable and can provide antioxidant protection for a long time.

[0024] In the present invention, after polydimethylsiloxane, dipentaerythritol tri-polyhydroxystearate and diisostearyl malate are compounded, they have good solubility for natural active extracts, the natural active extracts can stay in the compounded system for a long time, and the film formed by the compounded system can isolate oxygen for a long time.

[0025] In the present invention, compared with the organosilicon modified polysaccharide film-forming agent, the film formed by the organosilicon resin film-forming agent generally has higher hardness, tensile strength, and impact resistance, but poorer flexibility and relatively lower elongation, while the film formed by the organosilicon modified polysaccharide film-forming agent has higher elongation and better flexibility, and can provide better protection and durability. The compound use of the organosilicon resin film-forming agent and the organosilicon modified polysaccharide film-forming agent can take into account the mechanical strength, flexibility, breathability and comfort of the film, thereby increasing the makeup-lasting time of the liquid foundation while maintaining the breathability and comfort of the liquid foundation.

[0026] In the present invention, the solubility of the organosilicon-modified polysaccharide film-forming agent molecules is poor, and dipentaerythritol tri-polyhydroxystearate and diisostearyl malate have good solubility for the organosilicon-modified polysaccharide film-forming agent after compounding. Film-forming agent A and the organosilicon-modified polysaccharide film-forming agent are simultaneously dissolved in the compounding system of polydimethylsiloxane, dipentaerythritol tri-polyhydroxystearate and diisostearyl malate, and the film-forming agent A and the organosilicon-modified polysaccharide film-forming agent can cooperate with each other, so that the liquid foundation forms a film on the skin surface that takes into account mechanical strength, flexibility, breathability and comfort.

[0027] Preferably, the weight percentage of each component is as follows: 25-40 parts of water, 5-30 parts of volatile silicone oil, 0.1 to 1.5 parts of diisostearyl malate, 0.1 to 1.5 parts of dipentaerythritol tri-polyhydroxystearate, 0.1 to 5 parts of polydimethylsiloxane, Film-forming agent A5-10 parts, Film-forming agent B 0.1~1.5 parts, 0.1-2 parts of natural active extract.

[0028] Preferably, the volatile silicone oil includes one or more of cyclopentasiloxane, cyclohexasiloxane, and polymethylphenylsiloxane.

[0029] In the present invention, the volatile silicone oil is specifically selected from pentamethicone.

[0031] In the present invention, the film-forming agent A is specifically selected from trimethylsiloxysilicate.

[0032] Preferably, the film-forming agent B includes one or more of trimethylsiloxysilylcarbamoyl pullulan, budding pullulan polysaccharide, chitosan-modified water-based silicone polyurethane / acrylate, and carboxymethyl deacetylated chitosan.

[0033] In the present invention, the film-forming agent B is specifically selected from trimethylsiloxysilylcarbamoyl pullulan.

[0034] Preferably, the natural active extracts include one or more of rice yeast fermentation product filtrate, bitter orange flower oil, sturgeon caviar extract, astragalus membranaceus root extract, siler root extract, calendula flower extract, gastrodia elata root extract, and albizzia julibrissin flower extract.

[0035] Preferably, it also includes one or more of an emulsifier, a humectant, a color powder, and a dispersant.

[0036] Preferably, the emulsifier includes one or more of sorbitan sesquioleate, lauryl PEG-10 tris(trimethylsiloxy)silylethyl polydimethylsiloxane, and cetyl PEG / PPG-10 / 1 polydimethylsiloxane.

[0037] Preferably, the moisturizer includes one or more of 1,3-propylene glycol, butylene glycol, and ethylhexylglycerin.

[0038] In the present invention, the butanediol is selected from one or more of 1,2-butanediol, 1,3-butanediol, 1,4-butanediol and 2,3-butanediol.

[0039] In the present invention, the butanediol is specifically selected from 1,3-butanediol.

[0040] Preferably, the toner includes one or more of titanium dioxide, pigment yellow 42, pigment yellow 43, pigment red 101, pigment red 102, and zinc oxide.

[0041] Preferably, the dispersant includes one or more of polyglyceryl-3 polydimethylsiloxyethyl polydimethylsiloxane, polyhydroxystearic acid, octyldodecanol stearyloxy stearate, isocetyl stearyloxy stearate, triisostearin, and pentaerythritol tetraisostearate.

[0042] In the present invention, the dispersant is specifically selected from polyglyceryl-3 polydimethylsilyl hydroxyethyl polydimethylsiloxane.

[0043] Preferably, the volatile silicone oil is cleaned with an aqueous solution of ammonium sulfate.

[0044] Preferably, the polydimethylsiloxane is cleaned with an aqueous solution of ammonium sulfate.

[0045] In the present invention, the aqueous solution of ammonium sulfate can elute free impurities in volatile silicone oils and polydimethylsiloxane, which is beneficial to improving the purity of volatile silicone oils and polydimethylsiloxane, improving the quality of liquid foundation, and thus helping to prolong the lasting effect of the natural active extract.

[0046] On the other hand, a method for preparing a long-lasting moist film-forming liquid foundation comprises the following steps: Prepare the oil phase: stir and mix the oil, film-forming agent A, film-forming agent B and powder, and then cool to 0-4°C to obtain the oil phase; Preparation of water phase: Mix water and natural active extracts evenly at 0-4°C, and continue to cool to -8--3°C. Stir continuously during the cooling process to obtain crushed ice-like substances, which is the water phase; Blending degassing: At 0-4°C, mix the water phase and oil phase evenly, then slowly heat up to 8-10°C, stirring continuously during the heating process, and then let it stand until the temperature returns to room temperature to produce a long-lasting, hydrating, film-forming liquid foundation.

[0047] In the present invention, mixing water and the natural active extract at 0-4° C. is beneficial to reducing the volatilization of the natural active extract, thereby improving the utilization rate of the natural active extract.

[0048] In the present invention, the temperature of the crushed ice-like water phase particles is lower than that of the oil phase. When the oil phase encounters the crushed ice-like water phase particles, the temperature decreases and the fluidity decreases, forming a structure of oil-in-water phase particles. The oil phase forms a coating and protection for the water phase particles. In the subsequent heating process of the blending and degassing step, the water phase particles gradually melt. Due to the coating of the oil phase, the natural active extract dissolved in the water phase is not easy to escape and is retained in the liquid foundation system, thereby reducing the waste of the natural active extract due to volatilization and improving the utilization rate of the natural active extract.

[0049] In the present invention, the water-in-oil phase particles will automatically split into smaller droplets during the heating and stirring process in the subsequent blending and degassing step.

[0050] Preferably, in the step of preparing the aqueous phase, water and the natural active extract are mixed uniformly in an oxygen-free atmosphere.

[0051] In the present invention, the natural active extract is mixed with water in an oxygen-free atmosphere, which is beneficial to avoid oxidation of the natural active extract, thereby improving the utilization rate of the natural active extract.

[0052] Preferably, in the step of preparing the aqueous phase, the crushed ice-like substance is placed in a crusher at -10 to -8°C and crushed to uniform particle size.

[0053] In the present invention, after the crushed ice-like material is crushed, the uniformity of mixing the crushed ice-like water phase and the oil phase can be improved.

[0054] Preferably, in the blending and degassing step, after slowly heating to 8-10° C., degassing is first performed at 0.3-0.5 MPa, and the degassing process is continuously stirred, and then allowed to stand.

[0055] In the present invention, degassing is specifically performed at 0.5 MPa.

[0056] Preferably, in the blending and degassing step, the mixture is allowed to stand at room temperature.

[0057] In the present invention, during the process of standing and warming up at room temperature in the blending and degassing step, some substances in the natural active extract in the water phase gradually dissolve into the oil phase, and the standing and warming up process is conducive to the full association of diisostearyl malate with the natural active extract, thereby helping to increase the lasting effect of the natural active extract.

[0058] The materials involved in the present invention are introduced as follows: Pentamethicone (D5): Pentamethicone can provide lubrication and silky touch to liquid foundation, making it easy to apply evenly during use, thus improving the user experience. At the same time, due to its certain volatility, pentamethicone can dry quickly on the skin, thus helping the liquid foundation to set quickly.

[0059] Trimethylsiloxysilicate: ① Trimethylsiloxysilicate has good film-forming properties and can form a uniform thin film on the skin surface. The film formed by trimethylsiloxysilicate can reduce the migration of pigment particles, prevent uneven distribution of foundation color on the face, and help improve the uniformity, durability and anti-transfer properties of the foundation.

[0060] ② Trimethylsiloxysilicate is compatible with a variety of organic oils and silicone oils. The film formed has excellent waterproof and oil-proof properties, allowing the liquid foundation to maintain the integrity of the makeup even when sweating or with high oil secretion.

[0061] ③Trimethylsiloxysilicate can improve the adhesion of liquid foundation and provide a silky skin feel, enhancing the user experience.

[0062] Trimethylsiloxysilylcarbamoyl pullulan: ① Trimethylsiloxysilylcarbamoyl pullulan has good film-forming properties and can form a uniform thin film on the skin surface. The film formed by trimethylsiloxysilylcarbamoyl pullulan has excellent waterproof and oil-proof properties, which enables the liquid foundation to maintain the integrity of the makeup even when sweating or oil secretion is high, and helps to improve the durability and anti-transfer properties of the liquid foundation.

[0063] ②Trimethylsiloxysilylcarbamoyl branched starch is compatible with a variety of organic oils and silicone oils, which is beneficial to improve the adhesion of liquid foundation, making it adhere better to the skin, facilitating formula design and improving product stability.

[0064] Compared with the prior art, the advantages of the present invention include: (1) The present invention provides a long-lasting moist film-forming liquid foundation. After polydimethylsiloxane, dipentaerythritol tri-polyhydroxystearate and diisostearyl malate are compounded, the natural active extract can stay in the compound system for a long time, and the film formed by the compound system can isolate oxygen for a long time, thereby extending the duration of the natural active extract in the liquid foundation; (2) The present invention provides a long-lasting moist film-forming liquid foundation, in which dipentaerythritol tri-polyhydroxystearate and diisostearyl malate are compounded to have good solubility for organosilicon-modified polysaccharide film-forming agents, thereby helping to reduce the volatility of natural active extracts, protect natural active extracts, and dissolve organosilicon-modified polysaccharide film-forming agents; (3) The present invention provides a long-lasting hydrating film-forming liquid foundation, which prolongs the duration of the effect of the natural active extract in the liquid foundation, improves the utilization rate of the natural active extract, and is beneficial to reducing the amount of the natural active extract used, thereby helping to reduce the preparation cost of the liquid foundation.
