Description

A convenient, mild and efficient no-wash makeup remover spray sponge aerosol and preparation method thereof

【Technical field】

The invention relates to a convenient, mild and high-efficiency no-wash makeup remover spray sponge aerosol and a preparation method thereof, belonging to the technical field of cosmetic preparation.

【Background technique】

Makeup removal is one of the most important parts of skin care. Proper use of makeup remover products will not only make the cleaning work more effective, but also benefit the skin.

With the rapid development of the domestic makeup industry, the market importance of makeup remover products has become more prominent. There are several major types of makeup remover products on the market: makeup remover oil, makeup remover water, makeup remover milk, makeup remover soap, makeup remover cream, and makeup remover cream . The above types are relatively mature products in the market, but the type of makeup remover spray on the market is still in the stage of development. The types of makeup remover described above all need to be cleaned or wiped with foreign objects. The whole process is relatively cumbersome, which is contrary to the fast pace of life of today's consumers.

Under such market environment, it is also necessary to develop a convenient, mild and efficient leave-in makeup remover product.

【Content of invention】

The purpose of the present invention is to make up for the deficiencies of the prior art and provide a spray sponge aerosol that is mild, comfortable, convenient and simple, and has a high-efficiency makeup-removing effect.

Another object of the present invention is to provide a method for preparing the above-mentioned convenient, mild and high-efficiency leave-on makeup remover spray sponge aerosol.

In order to achieve the above object, the present invention adopts the following technical solutions:

A convenient mild and high-efficiency non-cleaning makeup remover spray sponge aerosol is characterized in that it includes a material liquid component composed of the following weight ratio components:

The sum of weight percentages of each component of the feed liquid component satisfies 100%.

The mild and high-efficiency makeup remover component described therein is made up of following weight percentage components:

PEG-20 Glyceryl Isostearate 3.00～5.00%

PEG/PPG/polytetramethylene glycol-8/5/3 glycerin 3.00～5.00%

The present invention also includes a propellant, and the weight percentage ratio of the feed liquid component and the propellant is as follows: 30-40% of the feed liquid component and 60-70% of the propellant.

The propellant in the present invention is a low-melting liquefied gas with a melting point of -50-0°C, preferably a mixed gas of two or more of dimethyl ether, liquefied petroleum gas, propane and butane. Under the action of pressure, the gas will eject the material evenly. If there is less gas, the material will not be sprayed out and no sponge will be formed. But when the gas content is high, the sponge will agglomerate. In addition, the ratio of material to gas is the same Important, when the gas weight: material weight < 2:1, the sponge is prone to breakage, so usually the gas weight: material weight > 2:1 is more suitable.

The mixed emulsion of acrylate polymer (INCI name: ACRYLAMIDESCOLYMER) in the present invention has a solid content of 40-50%. Preferably, the mixed emulsion of acrylate polymer is acrylamide copolymer, acrylic crosslinked polymer, acrylate crosslinked polymer, acrylic/beheneth-25 methacrylate copolymer and A mixture of two or more of the Acrylates/Beheneth-25 Methacrylate Copolymer. If the amount of the mixed emulsion of the acrylate polymer is below 55%, the formed sponge has weak viscosity and poor skin-adherence; if the amount is more than 62%, linear substances will come out when spraying, and the sponge cannot be formed.

The lower saturated fatty acid in the present invention is one or a mixture of stearic acid, palmitic acid, myristic acid and stearic acid. Since the lower saturated fatty acid becomes solid at the lower critical solution temperature, the mixed emulsion of the acrylate polymer becomes hard and forms a sponge with a certain hardness. A hard sponge will break during wiping; if the amount of low-level saturated fatty acid is higher than 12%, it will form lumps or the sponge will be too hard to wipe the skin, and it may also cause damage to the skin tissue of the face. harm.

The polyhydric alcohol in the present invention is one or a mixture of glycerin, sorbitol, dipropylene glycol, and dipropylene glycol. Hydrogen bonding between water and polyols slows down film formation and prevents water out. If the amount of polyol is less than 6%, the hydrogen bond formed will be weak, and when the sponge is pressed, the amount of water will be too large, which will affect the use feeling of the product; if the amount of polyol is higher than 10%, the hydrogen bond formed will be strong, and when the sponge is pressed , the water is not easy to come out, and cannot fully penetrate and dissolve the ingredients that need to be removed.

The mild and efficient cleansing component in the present invention is a mixture of PEG-20 glycerin isostearate and PEG/PPG/polytetramethylene glycol-8/5/3 glycerin. PEG-20 Glyceryl Isostearate is a high-efficiency and mild surfactant, crystal clear, warm and soft to the skin, easy to clean without leaving greasy residue. It will bring new vitality to the skin, smooth and soft touch, while moisturizing and nourishing sebum, regulating and increasing skin elasticity. PEG/PPG/polytetramethylene glycol-8/5/3 glycerin is an alkylene oxide derivative of vegetable glycerin and has high moisturizing properties. It is a very mild cleanser. Due to its high oil compatibility, it can be compatible with most of the oils used in make-up products. At the same time, it can lock the lipid components, improve the softness of the skin, and give the skin a long-lasting and pleasant skin feeling. Improves the problem that the skin is easy to degrease after cleaning, and at the same time prevents the skin from shrinking. It is a new type of "water-based moisturizing oil". PEG/PPG/polytetramethylene glycol-8/5/3 glycerin can form "ultra-fine emulsion" with oily substances, so as to achieve the effect of makeup removal. If the makeup remover component is less than 6%, it will affect the makeup remover effect of the product; if the makeup remover component is more than 10%, it will make the material body gather into a ball.

The ether emulsifier in the present invention is one or a mixture of oleth-2, oleth-10 and oleth-20 phosphate. The addition of emulsifier is mainly to make the material body form a stable and uniform emulsion. If the amount of emulsifier is less than 0.1%, the formed emulsion will be layered. If the amount of emulsifier is less than 1%, the skin feeling of the material body will change. astringent.

Other components added to the product of the present invention are conventional cosmetic additives, including preservatives and/or fragrances.

A method for preparing the above-mentioned convenient, mild and high-efficiency no-wash makeup remover spray sponge aerosol, characterized in that the preparation steps are as follows:

a. First, mix water with low-level saturated fatty acid, polyol, ether emulsifier and mild and high-efficiency makeup remover components, heat to 80-85°C, emulsify for 5-10 minutes, and homogenize at 3000rpm/min for 3-5 minutes, then cool down;

b. Slowly add the mixed emulsion of acrylate polymer when the temperature is lowered to 60-65°C, keep warm at 50-53°C and homogenize at 3000rpm/min for 3-5min, then cool down to 40°C and add conventional cosmetic additives, stir for 3min, wait for temperature When the temperature drops below 35°C, the material can be discharged to obtain the material liquid component;

c. Pour the propellant and the feed liquid components into the aluminum can together through external pressure.

Compared with prior art, the present invention has following advantage:

The invention develops a makeup remover product that can be carried, is simple, and does not need external objects and cleaning. Allowing consumers to quickly remove makeup on any occasion. The principle of this product is that the material body in the aerosol tank is a mixed emulsion of acrylates, fatty acids, polyols, heating and high-efficiency makeup remover components, which are well mixed and dispersed to form a jelly, which is a solid in a gas in physical form. , there are micro-particle jelly in the liquid; in the aerosol tank, in addition to the above-mentioned materials, there are some low-melting-point gases as propellants. When spraying, the emulsion-type materials can be pushed out evenly. It is usually an aluminum can, and the material body and the propellant are put into the aluminum can by external pressure. After spraying out, the propellant with a low melting point is quickly vaporized, and the fatty acid hardens in the air, and hardens to form a sponge. The formed sponge and The skin adhesion is good and the skin feels comfortable. By wiping and extruding, the mild and efficient makeup remover components and a small amount of water in the sponge ball penetrate into the skin and fully dissolve the makeup ingredients. Since the sponge ball contains a mixed emulsion of acrylates, it can adhere to the dissolved makeup ingredients, so as to achieve a cleansing effect. washing effect. Because the sponge has a certain hardness, it has a massage effect during the wiping process, and at the same time relaxes the skin, enlarges the pores, and fully removes makeup.
