Description

Method for manufacturing cosmetic composition using room-temperature emulsifying process}

The present invention relates to a cosmetic composition, and more particularly, to an environmentally friendly cosmetic composition manufacturing method using a room temperature emulsification process.

In cosmetics, emulsification technology is widely applied to lotions, creams, essences, massage creams, cleansing creams, makeup bases, foundations, eyeliners, mascaras, etc. In liquids such as water, oil-like liquids that are not mixed with each other are uniformly dispersed in the state of small particles of 0.1 to several tens of μm. Emulsion products look opaque and hazy, and are largely divided into macroemulsion, miniemulsion, and microemulsion according to the particle size of the emulsion.

A macroemulsion is a dispersed liquid-liquid with a particle size in the range of 1 to 100 μm. It is a thermodynamically unstable system that does not form spontaneously and effectively scatters light, so the droplets appear milky white because they are larger than the wavelength of light.

A miniemulsion is a specific type of emulsion obtained by shearing a mixture comprising two immiscible liquid phases, one or more surfactants and one or more cosurfactants (typical examples are hexadecane or cetyl alcohol). A microemulsion is a clear, thermodynamically stable, isotropic liquid mixture of oil, water and a surfactant, often in combination with a co-surfactant. The aqueous phase may contain salts and other components, and the "oil" may in fact be a complex mixture of different hydrocarbons. Physical and chemical methods include the hydrophilic-hydrophobic balance (HLB value) of the emulsifier, the concentration of the emulsifier, the emulsification temperature, and the method of adding the emulsifier. The physical method is a method of utilizing an emulsifying device that has a high shear force or can give a high pressure. The emulsification process is completed using a homo-mixer and a microfluidizer.

Emulsions are divided into oil-in-water (O/W) and water-in-oil (W/O) types depending on the form. In O/W type emulsion, oil is dispersed as particles in W/O type emulsion. The phase composed of particles is called "Internal Phase" or Dispersed Phase, and the phase in which particles are dispersed is called "Outer Phase" or Continuous Phase. Also, among W/O type emulsions, emulsions using silicone or silicone derivatives instead of oil as a continuous phase are referred to as W/S (Water in Silicone) emulsions.

Recently, silicone and silicone derivatives having unique physical properties and feeling of use are being used in basic cosmetics, makeup cosmetics, and hair products. Silicone has been used as an additive in a small amount in the cosmetic field in the early days, but it is used as a main raw material for products to the extent that the function or characteristics of silicone represent the main quality of cosmetics. The reason why silicone is widely used in cosmetics is, first, it has excellent lubricity and releasability (non-adhesiveness). Silicone has a lower surface tension than any hydrocarbon compound, so it is easy to diffuse into the skin or hair and serves to help the diffusion of other ingredients. In addition, compared to hydrocarbon-based raw materials, silicone has a relatively low stickiness and is comfortable to use. Second, the Si-O bond energy is large, so it has excellent thermal stability and oxidation stability, a high molecular weight, a small change in viscosity with respect to temperature change, and excellent permeability of oxygen or carbon dioxide, so it does not interfere with skin respiration. When used on hair, it gives continuous gloss and gloss. Third, it has excellent water repellency because it has no affinity for moisture. Since silicone has a large contact angle with water, when used as a raw material for cosmetics, it has excellent water resistance and oil resistance, preventing makeup from being easily erased by sweat or skin fat.

However, silicone has many excellent properties, but its compatibility with other raw materials is poor, so there are limitations in product application and formulation stabilization. In order to compensate for these drawbacks, silicone derivatives introducing various functional groups are being developed. Silicone derivatives are used as raw materials for cosmetics, such as oil, coating agents, surfactants, and powder treatment agents. Silicone as a coating agent is used for the purpose of maintaining the characteristics of cosmetics for a long time, and high-viscosity resinous or rubbery silicone is mainly used. Trimethylsiloxylic acid is used as resin-like silicone, and this type of silicone is formulated into skin care products or makeup products to improve makeup durability as a water- and oil-resistant coating agent.

Among various emulsification systems in the field of cosmetics, liquid crystal emulsification systems that are excellent in skin safety, improve the stability of emulsions, and control rheological properties are being applied. The liquid crystal emulsification system maintains the dispersed phase in the liquid crystal, and is used for the generation and stability of emulsion by increasing the strength of the structural interface film through the reduction of interfacial tension and the efficient arrangement of surfactant molecules. Liquid crystal is an intermediate state between a crystal and a liquid, and its molecular arrangement is not regular like a crystal, but it is not as irregular as a liquid, and exhibits fluidity and optical anisotropy intermediate between a solid and a liquid. Liquid crystal can also be used in a mixed system of surfactant, water, and oil, and has a structure in which water is dissolved in the hydrophilic group of the surfactant and oil is dissolved in the oleophilic group. It is not greatly affected by the manufacturing temperature and the type of oil phase component, can generate emulsified particles, and improves emulsion stability and water retention. Since this phenomenon is based on the interaction between amphiphilic molecules and water, it is possible to create emulsions with new functions and characteristics and to increase the emulsion stability of various emulsions by well controlling the formation conditions, structure, and physical properties of the multilayer structure.

However, general emulsifiers (eg, glyceryl stearate, cetearyl alcohol, etc.) are in a solid state and can be used only when heated to a high temperature. In addition, general thickeners (eg, carbomer, xanthan gum, etc.) are also not easily dissolved unless it is a high-temperature solvent. Because of this, the emulsification process is inevitably carried out in a state heated to a high temperature at which the emulsifier and the thickener can be dissolved, but there is a problem that is not environmentally friendly because carbon dioxide emissions increase due to high energy consumption. In addition, as it is performed in a heated state at a high temperature, there is a problem in that functional ingredients that are weak to heat cannot be mixed and emulsified together.

1 is a process chart of a cosmetic composition manufacturing method according to an embodiment of the present invention.

Hereinafter, embodiments of the present invention will be described in detail so that those skilled in the art can easily implement the present invention. This invention may be embodied in many different forms and is not limited to the embodiments set forth herein.

Referring to FIG. 1, the method for preparing a cosmetic composition according to an embodiment of the present invention includes a first step of preparing a first mixture in which a moisturizer containing at least one compound of diols and polyhydric alcohols and an aqueous phase part are mixed, a second step of preparing a second mixture in which a silicone derivative, an emulsifier, and a thickener are mixed, a third step of preparing a first emulsion by mixing the first mixture and the second mixture, and emulsification by mixing a solubilizing agent in the first emulsion It includes 4 steps to do, and as the steps 1 to 4 are performed at 20 to 40 ° C., energy consumption is small or little and is environmentally friendly.

First, as a first step of the present invention, a step of preparing a first mixture in which a moisturizer containing at least one compound of a diol and a polyhydric alcohol is mixed with an aqueous phase part is performed.

The diol and polyhydric alcohol may be known diols and polyhydric alcohols used as moisturizers in cosmetic compositions, and for example, the diol may be 1,2-hexanediol. In addition, the polyhydric alcohol may include at least one of butylene glycol, propylene glycol, dipropylene glycol, glycerin, and polyethylene glycol.

In addition, one or more compounds of the diol and polyhydric alcohol may be included in 20 to 50% by weight based on the total weight of the cosmetic composition, specifically preferably 5 to 15% by weight of glycerin, 10 to 20% by weight of butylene glycol, 1 to 10% by weight of polyethylene glycol, 5 to 20% by weight of propylene glycol, 5 to 20% by weight of dipropylene glycol, and 1,2-hexanediol to 10% by weight.

In addition, a known moisturizing component such as hyaluronic acid may be further included in addition to the diol and polyhydric alcohol, and the present invention is not particularly limited thereto.

In addition, the water phase part can be used without limitation in the case of a material forming the water phase of the cosmetic composition, and may be, for example, purified water. On the other hand, in the case of monohydric alcohol such as ethanol, it may rather dry the skin and inhibit long-term storage stability, so it may not be included. In addition, among polyhydric alcohols, diglycerin may also impair long-term storage stability, so it may not be included.

The first step may be performed using a known stirring device, and may be stirred using a homomixer, for example, and specific stirring conditions may appropriately be used for known conditions, so a special description thereof is omitted in the present invention.

On the other hand, in the first step, a hydrophilic skin improving component that is easily mixed or dissolved in the aqueous phase may be further mixed. The skin improving component may be a known cosmetic composition used for skin improvement, for example, various peptides such as copper tripeptide-1 and palmitoyl tripeptide-1, and natural extracts useful for the skin, such as evening primrose extract, japonica extract and camellia extract. The skin improving component may include, for example, 0.1 to 10.0% by weight of copper tripeptide-1, 0.1 to 10.0% by weight of palmitoyl tripeptide-1, 0.1 to 10.0% by weight of evening primrose extract, 0.1 to 10.0% by weight of primrose extract, and 0.1 to 10.0% by weight of camellia flower extract, based on the total weight of the cosmetic composition, but is not limited thereto.

Next, as a second step, a step of preparing a second mixture in which the silicone derivative, the emulsifier, and the thickener are mixed is performed. It should be noted that the second step is a step that is performed separately from the above-mentioned step 1, and there is no restriction on the order in which it is performed.

The second step is a step of mixing the silicone derivative, emulsifier, and thickener, and preferably can be homogenized and dissolved using an Agi-mixer. For example, step 2 may be performed at a speed of 3,000 to 5,000 rpm at 20 to 40 ° C using an aji-mixer, which may be advantageous to achieve the object of the present invention.

In addition, the silicone derivative may be used without limitation in the case of known silicone derivatives used in cosmetic compositions, and preferably may include at least one compound selected from the group consisting of cyclopentasiloxane/cyclohexasiloxane, cyclopentasiloxane, and dimethicone/vinyl dimethicone crosspolymer.

In addition, the thickener can be used without limitation in the case of known thickeners used in cosmetic compositions, preferably Ammonium Acryloyldimethyltaurate / VP Copolymer, Methacrylate crosspolymer, Dehydroxanthan Gum, Ammonium Acryloyldimethyltaurate / Beheneth-25 Methacrylate Cross It includes at least one compound selected from the group consisting of a polymer (Ammonium Acryloyldimethyltaurate/Beheneth-25 Methacrylate Crosspolymer) and an acrylate copolymer, and more preferably ammonium acryloyldimethyltaurate/VP copolymer (Ammonium Acryloyldimethyltaurate/VP Copolymer).

In addition, known emulsifiers used in cosmetic compositions can be used as the emulsifier without limitation, and preferably, Polyglyceryl-4 Caprate, Polyglyceryl-3 Polyricinoleate, PEG-10 Dimethicone, Cetyl PEG/PPG-10/1 Dimethicone 1 Dimethicone), at least one first emulsifier selected from the group consisting of Dimethicone/PEG-10/15 Crosspolymer, Dimethicone (Dimethicone/PEG-10/15 Crosspolymer, Dimethicone), and sodium acrylate/acryloyldimethyltaurate copolymer, cyclopentasiloxane, dimethicone/vinyldimethicone crosspolymer, and PEG/PPG-19/19di A second emulsifier, which is a silicone composite composed of methicone (Sodium Acrylate/Sodium Acryloyldimethyl Taurate Copolymer, Cyclopentasiloxane, Dimethicone/Vinyl Dimethicone Crosspolymer, PEG/PPG-19/19 Dimethicone), may be included.

As the second emulsifier, which is a silicone compound, is used in combination with the first emulsifier, it may be advantageous to further improve the emulsification of the silicone derivative and the stability in the cosmetic composition. In this case, preferably, the first emulsifier may include polyglyceryl-4 caprate and polyglyceryl-3 ricinoleate, and through this, a further increased effect on the emulsification and stability of the silicone derivative together with the second emulsifier, which is a silicone complex, can be expressed. If the first emulsifier contains components other than the above two components or does not include one of the two components, there is a concern that the above-mentioned synergistic effect will be insignificant. Further, more preferably, the first emulsifier may include polyglyceryl-4 caprate and polyglyceryl-3 ricinoleate in a weight ratio of 1: 1.5 to 2.0, which may be more advantageous in achieving the object of the present invention.

In addition, the first emulsifier and the second emulsifier may be included in a weight ratio of 1: 0.8 to 1.5, and through this, the above-described effects may be further expressed. If the weight of the second emulsifier is less than 0.8 times the weight of the first emulsifier, the above-mentioned effect through the second emulsifier may be insignificant. In addition, when the weight of the second emulsifier is more than 1.5 times, there is a concern that stability may be deteriorated, such as low-temperature and long-term stability in sunlight.

In addition, the silicone derivative is included in 5% by weight or more, more preferably 10% by weight or more, and even more preferably 15% to 25% by weight in the cosmetic composition, and despite the high content of the silicone derivative, excellent emulsification and high stability can be expressed due to proper mixing with the emulsifier and thickener. Meanwhile, the emulsifier may be included in 35 to 50 parts by weight based on 100 parts by weight of the silicone derivative, and the thickener may be included in 4 to 6 parts by weight based on 100 parts by weight of the silicone derivative, thereby achieving the object of the present invention. It may be advantageous.

On the other hand, in step 2, in addition to the above-mentioned components, a lipophilic component among skin-improving components useful for the skin may be mixed together. The lipophilic component may be a known lipophilic component used in cosmetic compositions and known to be useful for skin, and may be, for example, ceramide. The ceramide may be contained in 1 to 3% by weight based on the total weight of the cosmetic composition, but is not limited thereto.

Next, in the third step of the present invention, a third step of preparing a primary emulsion by mixing the first mixture and the second mixture is performed.

The first mixture and the second mixture may be mixed using a known stirrer, and may be emulsified using, for example, a homo-mixer. Mixing using the homomixer may be performed at a temperature of 20 to 40° C. at a speed of 1,000 to 2,000 rpm for 3 to 10 minutes, but is not limited thereto.

Next, as the fourth step of the present invention, a step of emulsifying by mixing the solubilizer with the primary emulsion is performed.

The solubilizer is a component that helps to improve stability by increasing the miscibility between the first mixture and the second mixture, and may be, for example, PEG 60 hydrogenated castor oil. In addition, in step 4, the primary emulsion may be secondaryly emulsified using a homomixer or a high-pressure microfluidizer. At this time, when using a homomixer, step 4 may be performed at a speed of 1,000 to 3,000 rpm at 20 to 40 ° C for 5 to 10 minutes, and when using a microfluidizer, step 4 may be performed at 950 to 1 It can be treated 2 to 3 times under a pressure condition of 200 bar.

In addition, after step 4, a defoaming process may be performed, and a finally stabilized water in silicone (W/S) emulsion may be obtained.

The cosmetic composition obtained through the above-described manufacturing method is a silicone derivative containing 5 to 15% by weight of cyclopentasiloxane / cyclohexasiloxane, 5 to 10% by weight of cyclopentasiloxane and 1 to 10% by weight of dimethicone / vinyldimethicone crosspolymer, a thickener containing 0.1 to 5.0% by weight of ammonium acryloyldimethyltaurate / Vpicopolymer, polyglyceryl-4 A first emulsifier containing 0.5 to 10 wt% of prate and 0.5 to 10 wt% of polyglyceryl-3 ricinoleate, 1 to 10 wt% of a second emulsifier that is a silicone complex composed of sodium acrylate/acryloyldimethyltaurate copolymer, cyclopentasiloxane, dimethicone/vinyl dimethicone crosspolymer, and PEG/PPG-19/19 dimethicone, A moisturizer containing 5 to 15 wt% of glycerin, 10 to 20 wt% of butylene glycol, 1 to 10 wt% of polyethylene glycol, 5 to 20 wt% of propylene glycol, 5 to 20 wt% of dipropylene glycol, and 1 to 10 wt% of 1,2-hexanediol, a solubilizer containing 0.1 to 2 wt% of PEG 60 hydrogenated castor oil, and It may include 1.5 to 53% by weight of skin improving ingredients.

In addition, the cosmetic composition obtained using the above-described room temperature emulsification process has an effect of improving skin moisturizing properties and improving skin texture, and is eco-friendly because energy consumption and carbon dioxide emission can be reduced as the manufacturing process is performed at room temperature.

In addition, cyclopentasiloxane, cyclopentasiloxane/cyclohexasiloxane, dimethicone/vinyldimethicone crosspolymer as a silicone derivative, ammonium acryloyldimethyltaurate/VP copolymer as a thickener, and ceramide as a skin improvement component were mixed with the oil phase emulsifier in the second step.
