Hereinafter, preferred embodiments of the present invention will be described. However, embodiments of the present invention may be modified in various other forms, and the scope of the present invention is not limited to the embodiments described below. In addition, embodiments of the present invention are provided in order to more completely explain the present invention to those with average knowledge in the art.

The inventors of the present invention have conducted a long study to find a manufacturing method for the natural plant to maintain its shape in cosmetics and melt on the epidermis of the skin only when the user uses it so that the ingredients of the natural plant penetrate into the skin. Was completed.

Meanwhile, in the present specification, the term "softening" is used, but as another example, the softening may be interpreted as a meaning of softening, softening, appropriately decomposing a tissue, etc., and for convenience, the term softening is used in the present specification. However, it is assumed that the above meanings can be included.

The cosmetic according to an embodiment of the present invention comprises a natural plant cosmetic composition comprising a softened natural plant and purified water, and the hardness of the softened natural plant is in the range of 　10ｇ to 　100ｇ in units of gravity. do. In addition, preferably, the hardness of the softened natural plant may be characterized in that it is in the range of 15g to 70g in units of gravity. Natural plants softened in the above range may be more effectively and appropriately softened.

The softened natural plant that satisfies the hardness range of the softened natural plant maintains its shape (or shape) before the user uses the softened natural plant in cosmetics, but the user puts the softened natural plant on the skin, If rubbed with an appropriate force, it is completely decomposed and most of the active ingredients of natural plants can penetrate into the user's skin. Therefore, it prevents the loss of the original active ingredients of natural plants so that most of the active ingredients are dissolved in the user's skin, while maintaining its shape in the cosmetic product before use, so that it has a very good visual effect and can have very excellent marketability. have.

The hardness of the softened natural plant is measured by a Texture Analyser (Model TAXT Express: Lamy rheology, France), a measurement speed of 1 mm/sec, and a distance of 5 mm between the probe of the Texture Analyzer and the sample. While maintaining the probe NO. It may be characterized in that it is performed by using a P/2 θ (diameter) 2 mm rod. In addition, the range of the gravitational unit described above may be characterized in that it is an average value of the result obtained by measuring the natural plant 10 or more times. This is to reduce the measurement error, and the error can be reduced by more accurately measuring the desired hardness in the present invention. Meanwhile, 1g of the gravity unit here means ^{9.8m/s 2.}

The hardness can be defined as the force required to reach the desired deformation, and in the case of the present invention, by going through a process of softening in an aqueous solution containing an acid, the hardness becomes an appropriate level and satisfies the above range. As described above, the softened natural plant can be completely decomposed and dissolved in the user's skin while maintaining its shape before use, as described above.

On the other hand, the water content of the softened natural plant may be characterized in that the range of 120% to 600% compared to the initially dried natural plant. The moisture content can be measured by weighing the softened plant increased compared to the dried natural plant using a scale by gravimetric method.

By satisfying the moisture content range, natural plants can be softened and exist in cosmetics while maintaining their shape. As a result, cosmetic users can visually feel excellent effects. In other words, consumers can visually feel that natural plants exist in actual cosmetics. In other words, in the conventional case, even if natural plants were used as a material for cosmetics, they were used as extracts, and its shape was difficult to see, or the shape was pulverized so that the shape could not be recognized, but satisfies the above range of moisture content change. The natural plant body is softened and exists in the cosmetic product and maintains its shape to the extent that it is possible to visually observe what kind of natural plant it is.

On the other hand, the tensile strength of the softened natural plant may be characterized in that 25% to 80% compared to the initially dried natural plant. The tensile strength may be performed by a standardized tensile strength measurement method, and a specimen may be prepared and measured in a tensile strength meter. On the other hand, the initial tensile strength may be partially different depending on the type of natural plant used, but the tensile strength after softening satisfies 25% to 80% compared to the tensile strength of the initial natural plant. You can pay. That is, by satisfying the range of change in the tensile strength, the natural plant body softened at the beginning can be easily decomposed during use while maintaining its shape.

In other words, by satisfying the above tensile strength range, natural plants are softened and exist in cosmetics while maintaining their shape, and when users rub softened natural plants in cosmetics on the skin, they are easily decomposed, thereby providing excellent visual effects. Even though it has, most of the active ingredients can be easily used by simply rubbing. In other words, consumers can easily utilize most of the active ingredients while visually feeling that natural plants exist in actual cosmetics.

Meanwhile, the cosmetic may include a moisturizing agent, a thickener, and an additive. The moisturizer is for preventing dryness of the skin, supplies moisture to the skin, prevents moisture loss to the outside, and has an effect of increasing the flexibility and elasticity of the skin. The moisturizing agent may include glycerin, butylene glycol, propylene glycol, methylpropanediol, xylitol, betaine, or oligopolysaccharide, but is not limited thereto. The thickener is for imparting viscosity to cosmetics to some extent, and includes xanthan gum, hydroxyethyl cellulose, carbomer, acrylate/C10-30 alkyl acrylate crosspolymer, sodium polyacrylate or acrylate copolymer It can be, but is not limited thereto. In addition, the cosmetic of the present invention may include some additives, and the additive may include at least one or more of a preservative, a solubilizing agent, a pH adjusting agent, a fragrance, and a coloring agent. The preservative may include methylparaben, propylparaben, phenoxyethanol, sodium benzoate, potassium sorbate or chlorophenesin, and may prevent the components of cosmetics from being spoiled. In addition, the solubilizing agent may be for dissolving a component containing a fat component in an aqueous solution during the manufacturing process, and polysorbate 20, polysorbate 60, PEG-40 hydrogenated castor oil or PEG-6 Caprylic/capric glycerides. The pH adjusting agent may be for adjusting the cosmetic product to a level that is not harmful to the human body, and may include citric acid, lactic acid, glycolic acid, or sodium citrate. The fragrance and colorant are for a user's sense of smell or visual effect, and may include fragrances, essential oils, organic pigments, etc., but are not limited thereto.

Meanwhile, the cosmetic may include 1 to 40% by weight of the natural plant cosmetic composition, 0.1 to 70% by weight of the moisturizer, 0.001 to 10% by weight of the thickener, and 0.1 to 30% by weight of the additive.

By satisfying the range of the natural plant cosmetic composition, it is possible to enjoy the effect of the softened natural plant desired in the present invention. In addition, by satisfying the range of moisturizers, the effect of the softened natural plant desired in the present invention and appropriate viscosity while enjoying the effect of supplying moisture to the skin, preventing moisture loss to the outside, and increasing the flexibility and elasticity of the skin. Etc. can produce the same effect. In addition, by satisfying the range of the thickener, the viscosity can be adjusted to a level that is convenient for the user, while appropriate mixing with other ingredients is possible.

In the natural plant cosmetic composition, the mixing ratio of the softened natural plant and the purified water may be mixed at a weight ratio of 1:1 to 1:10. The natural plant softened in the composition range is to be described later. During the process, excessive decomposition in the process of being added to the cosmetic composition can be prevented, and decomposition in the process of removing purified water and natural plants softened during storage can be prevented from becoming hard again.

Hereinafter, a cosmetic manufacturing method for manufacturing the cosmetic will be described.

A cosmetic manufacturing method according to an embodiment of the present invention includes preparing a dried natural plant, impregnating the dried natural plant with an aqueous solution containing acid and purified water, and adding the aqueous solution to 40°C to 95°C. Preparing a natural plant softened by the step of softening for a time of 30 minutes to 240 minutes at a temperature in the range, and washing the natural plant softened by the softening step using purified water, the softened natural Preparing a softened natural plant cosmetic composition by mixing purified water with a plant, dissolving a moisturizing agent in the first reaction tank, adding a thickener to the first reaction tank, mixing and dissolving purified water and a pH adjusting agent 1 Injecting into the reaction tank, mixing an additive including a preservative, solubilizing agent, flavoring or coloring agent into the first reaction tank, and introducing the softened natural plant cosmetic composition into the first reaction tank do.

Preparing the softened natural plant includes preparing a dried natural plant, impregnating the dried natural plant with an aqueous solution containing acid and purified water, and adding the aqueous solution in the range of 40°C to 95°C. It includes the step of softening at a temperature for a time of 30 to 240 minutes, and washing the natural plant softened by the softening step using purified water.

On the other hand, the dried natural plant may be any natural plant that exists in nature, for example, rose, sunflower, chrysanthemum, calendula, cornflower, chamomile, morning glory, chamomile, balsam, cherry tree, green tea, hibiscus, peppermint , Centella asiatica, machihyeon, mugwort, Yeobasanta, dandelion, plantain, Eoseongcho, aloe, cheonnyeoncho, white willow, or centennial herb.

For example, rose petals contain a large amount of polyphenols and their derivatives, which have excellent antioxidant effects, and contain large amounts of essential oils, so when used on human skin, they are used to maintain skin elasticity and maintain health. The effect is very good. In addition, in the case of the present invention, since most of the above active ingredients are preserved in the rose petals and are present in the cosmetic composition and cosmetics containing the same, the visual effect is excellent, as well as the utilization of the active ingredient is maximized. can do

Next, the dried natural plant is impregnated with an aqueous solution containing an acid and purified water. As a non-limiting example, the dried natural plant may be impregnated to completely wet the aqueous solution containing the acid and purified water.

Meanwhile, the acid may include a carboxyl group or a functional group of sulfonic acid. The acid may include, for example, an organic acid or an inorganic acid. As a specific example, the acid is an organic acid containing at least one or more of citric acid, tartaric acid, lactic acid, glycolic acid, formic acid, malic acid, oxalic acid, salicylic acid, ascorbic acid, citric acid, and gluconodeltalactone, or It may contain inorganic acids including at least one or more of phosphoric acid and carbonic acid. However, it is not limited thereto.

The acid can soften natural plants by partially cutting the bonds between celluloses present in natural plants by acidic functional groups such as carboxyl groups or sulfonic acids. I can. As a result, natural plants are softened while maintaining their shape, and when a user uses cosmetics, it is possible to disintegrate cellulose with only the force of rubbing with a finger. As a result, while maintaining the shape of the natural plant in a softened state, when the user uses it, it is completely disintegrated with little force, and most of the active ingredients of the natural plant can penetrate into the user's skin.

In the case of cosmetics using natural plants, the method was to heat, press, distill, or extract the plants, or to contain only finely pulverized natural plants inside the cosmetics.In the case of the first method, the required active ingredients There was a problem that it was extracted only in a very small amount and was simply used in the form of an extract, and in the case of the second method, it was impossible to use a separate visual effect or the active ingredient contained in the plant except that it was added even though it contains natural plants. There was a problem.

However, according to the cosmetic manufacturing method according to the present invention, the natural plant body maintains its shape even in the final product, so the visual effect is excellent, and the user leaves the natural plant body with the remaining shape on his or her skin slightly. The effect is very excellent because most of the active ingredients remaining in the natural plant can be absorbed into the user's skin because it is completely disintegrated when only the force of is applied.

Next, the natural plant is subjected to a step of softening the aqueous solution impregnated with purified water and acid at a temperature ranging from 40°C to 95°C for a period of 30 minutes to 240 minutes. The softening step is a non-limiting example, by impregnating a natural plant body in an aqueous solution mixed with purified water and an acid prepared in advance to satisfy the temperature range and then performing the step of softening for the amount of time, or impregnating the natural plant body in the aqueous solution at the temperature. After raising the temperature to the range, it may be subjected to a step of softening for the above time. Meanwhile, in the present specification, the term "softening" is used, but as another example, the softening may be interpreted as a meaning of softening, softening, appropriately decomposing a tissue, etc., and for convenience, the term softening is used in the present specification. However, it is assumed that the above meanings can be included.

When the temperature of the aqueous solution is less than 40° C., the effect of the softening process is insignificant, and the softening degree may be reduced, and thus, complete decomposition may not be performed in the process of use by the user. In addition, when the temperature of the aqueous solution exceeds 95° C., the natural plant may be completely decomposed and the shape may not remain. In addition, when the softening step is performed in the above temperature range for less than 30 minutes, the degree of softening is insignificant and when the user uses it, the natural plant may not be completely decomposed or broken, and if the softening process goes through the process of softening for more than 240 minutes , The natural plant may be completely decomposed so that its shape may not remain.

As a preferred example, the step of softening the aqueous solution may be characterized in that it is performed to soften for a time period of 60 minutes or more to 180 minutes or less at a temperature in the range of 70 ℃ or more to 90 ℃ or less. The natural plant softened in the above range can be prevented from being broken or decomposed, and when the user uses the softened natural plant, it can be easily decomposed.

In addition, the step of softening the aqueous solution may be characterized in that it is performed to soften for a time of 30 minutes or more to 150 minutes or less at a temperature in the range of more than 90 ℃ to 95 ℃ or less. The natural plant softened in the above range can be prevented from being broken or decomposed, and when the user uses the softened natural plant, it can be easily decomposed.

When the temperature range of the present invention and the softening time are exceeded, the shape of the softened natural plant to be obtained in the present invention is maintained, and the natural plant is completely decomposed when the user uses it, so that the active ingredient penetrates the user's skin. It may not be possible.

On the other hand, after the softening step, it may further include checking whether the natural plant is softened as desired. The step of confirming whether it is softened is a non-limiting example, and after the softening step, the softened natural plant is taken out, placed on the back of the hand, and rubbed with a certain force. Meanwhile, as a non-limiting example, when less softening is performed in the step of confirming, it may include repeatedly performing the softening step for a time in the range of 15 minutes or more to 45 minutes or less. That is, when the softening is less, the step of softening may be repeated and performed.

The step of confirming whether it is softened is a non-limiting example, and after the softening step, the softened natural plant is taken out, placed on the back of the hand, and rubbed with a certain force. In addition, it can be checked by comparing the tensile strength of dried natural plants using a tensile strength meter. As a non-limiting example, the tensile strength may vary depending on the type of natural plant to be used. Preferably, the tensile strength of the softened natural plant may be 25% to 80% compared to the initially dried natural plant.

In addition, the step of checking whether the natural plant has been softened may include the hardness, adhesiveness, springiness, cohesiveness, guminess, and chewiness of the natural plant that has undergone the softening step. And it may be characterized in that it is performed by selecting and measuring any one of the resilience (Resilience). In addition, the step of checking whether the natural plant has been softened may include the hardness, adhesiveness, springiness, cohesiveness, guminess, and chewiness of the natural plant that has undergone the softening step. And it may be characterized in that it is performed by selecting and measuring any one of the resilience (Resilience). The hardness may be characterized by checking whether it is within the range described above. For example, the hardness range may be in the range of 　10ｇ to 　100ｇ in the unit of gravity, for example, it may be characterized by checking whether the range is in the range of 15g to 70g in the unit of gravity.

In addition, the adhesiveness (Adhesiveness) may be in the range of -0.2 g.sec to 　-1.2 g.sec, for example, it is characterized by checking whether the range of -0.3 g.sec to 　-1.0 g.sec. I can.

In addition, the elastic force (Springiness) may be in the range of 　 0.03 to 　 0.22, for example, it may be characterized by checking whether it is in the range of 0.04 to 　 0.11.

In addition, the cohesiveness may be in the range of 　 0.2 to 　0.5, and for example, it may be characterized by checking whether the range is in the range of 0.35 to 0.45.

In addition, the guminess may be in the range of 　 1 to 　 100, and for example, it may be characterized by checking whether the range is in the range of 5 to 　 40.

In addition, the chewiness may be in the range of 　 0.1 to 　 4, and for example, it may be characterized by checking whether the range is in the range of 0.5 to 2.5 　.

In addition, the resilience may be in the range of 0.1 to 1.8, for example, it may be characterized by checking whether the range is in the range of 0.3 to 1.

The hardness (Hardness), adhesion (Adhesiveness), elasticity (Springiness), cohesiveness (Cohesiveness), guminess (Gumminess), chewiness (Chewiness) and recovery (Resilience) measurement of the Texture Analyser (Model TAXT Express: Lamy rheology, France) It is measured by the equipment, and the measurement speed is 1mm/sec, and the probe NO. It may be characterized in that it is performed by using a P/2 θ2mm rod. In addition, the range of the gravitational unit may be an average value of a result obtained by measuring the natural plant 10 or more times.

Meanwhile, as a non-limiting example, when less softening is performed in the step of confirming, it may include repeatedly performing the softening step for a time in the range of 15 minutes or more to 45 minutes or less. That is, when the softening is less, the step of softening may be repeated and performed.

Repeatedly performing the softening step may be performed while further heating to a temperature in the range of 5° C. or more to 10° C. or less compared to the temperature of the previous softening step, and is not limited thereto. It may be characterized in that it is performed while reducing the time in the range of minutes or less. Thereby, it is possible to more elaborately control the degree of softening of the natural plant.

Next, it goes through the step of washing the natural plant softened by the softening step using purified water. The regular washing step is to remove residual acid after the softening process is completed, and may prevent natural plants from being continuously softened by the residual acid. Meanwhile, as a non-limiting example, the washing step includes the purified water It may be characterized in that it is repeatedly performed about 3 to 6 times by using. This is to obtain the desired pH of the softened natural plant.

In addition, the washing step may be performed so that the pH of purified water, which has been washed by the washing step, is in the range of 2.5 or more to 4.5 or less. In other words, this is to remove the acid remaining in the natural plant, and when it is removed to some extent, the acid partially remaining in the softened natural plant is mixed with the purified water, and if the pH range of the purified water satisfies the above pH range, the softening The pH of the natural plant can be considered to be substantially the same as that of purified water. Therefore, if the pH of the softened natural plant is 2.5 or more to 4.5 or less, that is, the pH of the washed purified water is in the range of 2.5 or more to 4.5 or less, the washing step can be completed.

Meanwhile, as a non-limiting example, preparing the dried natural plant may further include pulverizing the natural plant to a size of 50 μm or more to 10,000 μm or less. This may be for softening the natural plant to a desired level appropriately in the present invention in cosmetics manufactured through the above manufacturing process.

Next, a step of preparing a softened natural plant cosmetic composition is performed by mixing purified water with the softened natural plant. The mixing ratio of the softened natural plant and the purified water may be mixed at a weight ratio of 1:1 to 1:10. As mentioned above, the natural plant softened in the composition range is in the process of manufacturing cosmetics, which will be described later. It can prevent excessive decomposition in the process of being added to the cosmetic composition, and can prevent decomposition in the process of removing purified water and the phenomenon that the natural plant softened during storage is dried and hardened again.

On the other hand, the cosmetic manufacturing method includes the step of dissolving a moisturizing agent in a first reaction tank. More specifically, the cosmetic composition containing the moisturizing agent may be added to a manufacturing kiln and stirred sufficiently to dissolve completely. The moisturizing agent may contain one or more of glycerin, butylene glycol, propylene glycol, methylpropanediol, xylitol, betaine, and oligopolysaccharide, or several moisturizing agents.

Next, it includes the step of injecting a thickener into the first reaction tank. The thickener is for imparting viscosity to cosmetics to some extent, and may include xanthan gum, hydroxyethyl cellulose, carbomer, acrylate/C10-30 alkyl acrylate crosspolymer, sodium polyacrylate or acrylate copolymer. After the thickener is added to the first reaction tank, it may be sufficiently stirred so that it is completely dispersed.

Next, it includes the step of mixing and dissolving purified water and a pH adjusting agent, and introducing them into the first reaction tank. The purified water and the pH adjusting agent may be mixed and dissolved in a separate reaction tank, and the dissolved purified water and the pH adjusting agent may be added to the first reaction tank and stirred sufficiently to be neutralized.

Next, it includes a step of mixing an additive including a preservative, a solubilizing agent, a flavoring agent, or a colorant, and introducing it into the first reaction tank. The additives may be mixed and dissolved in a separate reaction tank, introduced into the first reaction tank, and then stirred so that they are completely dispersed. The additive has already been described while describing the cosmetic of the present invention, and redundant descriptions will be omitted.

Meanwhile, as a non-limiting example, after the reaction of the first reaction tank is completed, the step of removing air bubbles remaining in the reactant may be performed, and this is widely known in the art, and a detailed description thereof will be omitted.

On the other hand, the softened natural plant cosmetic composition may be characterized in that it is included in the range of 0.1% to 20% by weight of the total cosmetics. By satisfying the above range, when the natural plant cosmetic composition is added in an amount of less than 0.1% by weight, the amount of the natural plant cosmetic composition is very insignificant compared to the content of the rest of the cosmetic composition, so that the meaning of containing the natural plant is lost.In severe cases, it may be mistaken as a foreign substance other than a natural plant. . When the natural plant cosmetic composition is added in an amount of 20% by weight or more, it contains too much natural plant compared to the content of the rest of the cosmetic composition, resulting in extremely poor feeling of use, and the effect that the cellulose of the natural plant affects the feeling and stability of the entire cosmetic product. Can occur.

Hereinafter, the present invention will be described in more detail through specific examples. However, the following examples are intended to help the understanding of the specification, and the following content does not limit the content of the present invention.

Experimental Examples 50 to 56

The results of Examples 41 to 49, Examples 53 to 61, and Examples 65 to 73 of Comparative Examples 14 to 16, Comparative Examples 18 to 20, and Comparative Examples 22 to 24 in which an acid is not separately added to the softened calendula petals Take out the phosphorus calendula petals and measure hardness, adhesiveness, springiness, cohesiveness, guminess, chewiness, and resilience, respectively, and sequentially in FIGS. 19 to 25 below. Represented by.

The measurement was measured by a Texture Analyzer (Model TAXT Express: Lamy Rheology, France), a measurement speed of 1 mm/sec, and a distance of 5 mm between the probe of the Texture Analyzer and the sample for a period of 5 sec. Probe NO. This was done by using a P/2 θ2mm rod. The measurement was performed 10 times each using calendula petals, which are the results obtained in each of the Examples and Comparative Examples in order to reduce errors and obtain more accurate information. On the other hand, while the measurement was performed, there were occasional cases where a sample with an excessively large error range was occasionally present, but this was determined as a problem of the material itself, a problem of the measurement method, and some error of the measuring equipment and was excluded from the data.

When explaining the process of Experimental Examples 50 to 56 in more detail, first, 10 or more of the calendula petals, each of which passed through the processes of Examples and Comparative Examples, were taken out with tweezers and overlapped with each other on a rectangular metal tray as shown in FIG. 4. It should be moved and listed. At this time, since the number of samples to be measured is large and drying at room temperature during the measurement time for other samples, an error of the sample may occur. The foil was covered as shown in FIG. 5 so as not to be dried. Next, as shown in FIG. 6, the probe of the texture analyzer was positioned in the middle of the petals, and each petal was measured. At this time, the probe was positioned in the middle of the petal sample.

Meanwhile, in the graphs of FIGS. 19 to 25, in the case of the comparative examples, the average value of all the results for each value of the comparative example was input, and in the case of the examples, the result of measuring 10 times of petal samples corresponding to each condition was measured. Input was averaged. In the graphs of Figs. 19 to 25, the leftmost part of the horizontal axis inputs the comparative example, and the rest of the conditions input temperature, time, and acid concentration from the bottom to the top. For example, the case described as 70.60.2CA means that the softening was performed for 60 minutes under the condition of 70°C, and the concentration of the acid was 2% by weight. In addition, the vertical axis sequentially inputs values of hardness, adhesiveness, springiness, cohesiveness, guminess, chewiness, and resilience for each of the drawings.

Its unit is the hardness (Hardness) means g in the unit of gravity, the adhesiveness (Adhesiveness) means g.sec, and the elasticity (Springiness) is the time from the second graph to the peak in the measuring device of the present invention. It is a value divided by the time from the origin to the peak of the graph, and the unit for this is a dimensionless unit, and cohesiveness is the force that maintains the object as it is, and the first bite (probe When the area created by the first press using) is called Area 1, and the area generated by the second bite (when pressed the second time using a probe) is called Area 2, it is calculated as Area 2/Area 1. The unit is a dimensionless unit, and gumminess refers to a property that makes a semi-solid sample in a swallowable state, and the unit can be called a dimensionless unit. (Chewiness) refers to the property of making a solid sample into a swallowable state. The unit can be called a dimensionless unit, and the unit of resilience can be called a dimensionless unit.

As shown in the result of Experimental Example 50, in the case of the softened petals in the cosmetic composition included in the cosmetic, it was confirmed that the hardness (Hardness) satisfies the range of 　10ｇ to 　100ｇ in the unit of gravity, and preferably 15g to 70g It was found that the range was satisfied.

Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and variations are possible without departing from the technical spirit of the present invention described in the claims. It will be obvious to those of ordinary skill in the field.
