Description

TECHNICAL FIELD The cosmetic composition having increased texture and shape restoration ability, and its manufacturing method TECHNICAL FIELD

The present invention relates to a cosmetic composition having an increased texture and shape restoration ability, and a method for manufacturing the same, and more particularly, it has an increased texture, so that the effect of improving elasticity can be intuitively recognized by the user, and has shape restoration ability on the skin. It relates to a cosmetic composition having an immediate anti-wrinkle effect when applied and a method of manufacturing the same.

The skin system, an organ covering the outside of the body, consists of three layers from the outside: the epidermis, the dermis, and the subcutaneous fat layer. Since the skin is in direct contact with the external environment, it acts as a barrier against harmful external stimuli such as temperature, humidity, and ultraviolet rays, and also prevents the leakage of moisture and electrolytes in the body, and regulates body temperature, touch, pressure, pain, And it is responsible for various functions such as performing sensory functions for temperature stimulation, performing immune functions, synthesizing vitamin D, and expressing abnormalities in internal organs.

However, as we age, the secretion of various hormones that regulate metabolism internally decreases, the function of immune cells and the activity of cells decrease, and externally, various kinds of ultraviolet rays caused by the sun's rays or environmental pollution increase. Skin cells are damaged due to excessive physical and chemical irritation due to exposure to contaminants, and the normal function of the skin is deteriorated due to poor cell proliferation, spots caused by melanin deposition, freckles, wrinkles, loss of elasticity, keratinization, etc. Aging phenomenon occurs.

In order to prevent skin aging and damage caused by such internal and external factors, and to maintain healthier and more beautiful skin, physiologically active substances obtained from various animals, plants, microorganisms, etc. are used in addition to cosmetics to maintain the skin's own function. Efforts to maintain skin health by activating skin cells and promoting skin metabolism are continuing, and cosmetics and external preparations for skin with such functions are being developed.

In particular, as an anti-aging cosmetic composition with such a function, various skin protective ingredients such as retinol, vitamin X, flavonoids, and tocopherol, which have the function of preventing skin aging or slowing the progression rate by inhibiting the generation of reactive oxygen species, are contained. Although contained cosmetics or skin external preparations have been developed, such cosmetics or skin external preparations have a problem in that their potency is low in the final formulation, and their efficacy is mild and skin irritation is severe.

Accordingly, cosmetic compositions and skin external preparations that prevent skin aging by adding natural extracts have been developed, but the effect of preventing skin aging due to natural extracts is substantially insignificant, and ingredients other than the active ingredients contained in natural extracts are being developed. As a result, side effects such as unpredicted rash and erythema may occur, so the use of natural extracts is cautious.

In addition, the anti-aging effects of these products are visible only when the cosmetic composition is used for a long period of time, but recent consumers want products that can be effective in a short period of time, so they immediately improve skin wrinkles and elasticity. There is a trend of increasing preference for formulations that can be effective.

The step of preparing the second aqueous phase component includes sodium polyacrylate, ammonium acryloyldimethyltaurate/VP copolymer (Ammonium acryloyldimethyltaurate/VP copolymer), and hydroxypropylmethylcellulose in the first aqueous phase component. ) May be a step of sequentially mixing.

The cosmetic composition of the present invention has the ability to restore shape and has an immediate wrinkle improvement effect when applied to the skin, and after using the cosmetic composition using a tool such as a spatula, the cosmetic composition contained in the container returns to its original shape. It has the advantage of being able to use it neatly without any traces of use.

In addition, the elasticity improvement effect can be intuitively recognized by the user due to the increased texture.

In addition, according to the manufacturing method of the cosmetic composition of the present invention, the component having the shape restoration ability contained in the cosmetic composition is more uniformly and stably mixed, and there is an effect of improving the shape restoration ability.

Before describing in detail through preferred embodiments of the present invention, terms or words used in the present specification and claims should not be construed as being limited to a conventional or dictionary meaning, but a meaning consistent with the technical idea of the present invention. And should be interpreted as a concept.

Throughout this specification, when a certain part "includes" a certain component, it means that other components may be further included rather than excluding other components unless otherwise stated.

In general, a surfactant having a hydrophilic group and a lipophilic group in the molecular structure is used as an emulsifier in order to mix the oily component and the water phase component constituting the cosmetic composition. The shape included in the cosmetic composition having the increased texture and shape restoration ability of the present invention When a general emulsifier is used as a restoring agent or a functional ingredient, the oil phase component and the aqueous phase component are unstablely mixed, and the function thereof is deteriorated.

In other words, unstable phenomena such as a shape restorer and a functional component are mixed unevenly with other aqueous or oily components, a layer is formed, or a component forming a micelle is aggregated with each other, or the functional component is separated. There was a problem that the stretched texture and shape restoration function were not sufficiently expressed.

In the present invention, an emulsifier capable of emulsifying a shape restorer and a functional ingredient most preferably is used to prevent such incomplete emulsification and to enable a uniform, long-term stable emulsification, and emulsify in multiple stages in the manufacturing step. By using the method to achieve the above object.

First, the present invention relates to a cosmetic composition having an increased texture and shape restoration ability, and has an elongated texture such as a snail cream, so that the user can intuitively recognize the elasticity improvement effect to the user, and has a shape restoration ability to make the skin uneven Even if applied properly, the cosmetic composition is uniformly dispersed by the shape restoration ability, and during this process, the skin wrinkles are immediately spread out and elasticity is provided to the skin.

In addition, after taking the cosmetic composition contained in the container using a spatula or hand, the surface of the cosmetic composition changes flat by the shape restoration function after a predetermined period of time, so that even if it is used several times, there is an advantage that it can be used neatly without becoming messy. .

The cosmetic composition having such an elongated texture and shape restoration ability includes 5 to 30% by weight of a moisturizing agent, 0.04 to 5.25% by weight of an additive including an oil-soluble additive and/or a water-soluble additive, 0.5 to 5.1% by weight of an emulsifier, and 0.3 to 3.1 of a shape restoration agent. % By weight, 0.1 to 1.9% by weight of a thickener, and the remaining amount of purified water.

The moisturizing agent is added to provide moisture and oil to the skin, and to form a film on the skin surface to prevent moisture loss to the outside and inflow of foreign substances from the outside.Polyol may be included as such a moisturizing agent, preferably polyol and It can contain all oil-soluble moisturizers. At this time, the oil-soluble moisturizing agent may include silicone oil, synthetic oil, and vegetable oil.

In particular, polyols not only function as a moisturizing agent, but also function as a solvent for uniformly dissolving the shape restorer, so it is preferable to be used as a moisturizing agent in the cosmetic composition of the present invention, and silicone oil is added to obtain an effect of improving application properties. It is desirable.

In this case, as a moisturizer, polyol and silicone oil may be mixed and used in a weight ratio of 1:0.1 to 0.3, and if the content of polyol is insufficient, the shape restoration ability to be described later is not uniformly dissolved and the shape restoration ability decreases. When the content of is insufficient, it is difficult to obtain an effect of improving application properties, and when the content of silicone oil is included in an excessive amount, a problem of lowering the feeling of use due to stickiness occurs, so it is preferable to use a moisturizing agent mixture mixed in the above-described weight ratio.

On the other hand, the moisturizing agent may be included in an amount of 5 to 30% by weight, and when it is contained in less than 5% by weight, the moisturizing effect is insignificant, it is difficult to dissolve the shape restorer uniformly, and when it exceeds 30% by weight, excessive oil content As a result, problems such as increase in sebum and occurrence of trouble may occur, and the feeling of use may be poor due to stickiness, so it is preferable to be included within the above-described weight range.

Among the ingredients that can be used as a moisturizer, polyol is a polyhydric alcohol having two or more hydroxyl groups (-OH), which provides a moisturizing effect and is added to improve shape restoration ability by uniformly dissolving a shape restoration agent to be described later.

These polyols methyl Gluceth-20, Glycereth_26, Glycerine, Polyethyleneglycol, Propyleneglycol, Dipropyleneglycol, 1,3 -Butylene glycol (Butyleneglycol), hexylene glycol (Hexyleneglycol), sorbitol (Sorbitol), etc. may be used, preferably glycerin (Glycerine), dipropylene glycol (Dipropyleneglycol) and 1,3-butylene glycol (Butyleneglycol) Mixtures of can be used.

Glycerin has a moisturizing effect and gives viscosity to the cosmetic composition, so it can further maximize the moisturizing effect by lowering the content of additional thickeners. In addition, since it has a skin soothing effect, it can also be used by users with sensitive skin. have.

Like glycerin, 1,3-butylene glycol has moisturizing and viscosity increasing functions, and in addition, it has a conditioning effect that makes the skin soft and supple, and dipropylene glycol has an excellent moisturizing effect.

Therefore, when using a mixture of glycerin, 1,3-butylene glycol, and dipropylene glycol as a polyol, it is preferable to use a mixture thereof, since it is possible to obtain thickening, skin soothing and conditioning effects in addition to the moisturizing effect. In order to maximize the effect, it is more preferable to use a polyol mixture in which glycerin, 1,3-butylene glycol, and dipropylene glycol are mixed in a weight ratio of 1:8-12:3-6.

Silicone oil, which can be used as a moisturizer, is added to improve moisturizing power and improve spreadability.Since it plays a role of removing air bubbles, it also functions to improve skin adhesion by preventing the cosmetic composition from being pushed by micro-bubbles. Perform.

Silicone oils include methicone, dimethicone, cyclomethicone, diphenylsiloxy phenyl trimethicone, polydimethylsiloxane, methylphenyl polysiloxane, and Methylcyclo polysiloxane, Octamethylcyclo tetrasiloxane, Decamethylcyclo pentasiloxane, Dodecamethylcyclo hexasiloxane, tetradecamethyl hexasiloxane and Tecamethyl hexasiloxane Methyl trisiloxane (Octamethyltrisiloxane) or the like may be used.

Preferably, a silicone oil mixture in which diphenylsiloxyphenyltrimethicone and dimethicone are mixed in a weight ratio of 1:4 to 8 may be used, and in this case, a conditioning effect can be obtained in addition to the moisturizing power, spreadability, and antifoaming function. .

The additive is added to prevent aging and improve coloration and wrinkles due to aging, and may be used in an amount of 0.04 to 5.25% by weight, and when used in an amount less than 0.04% by weight, it is difficult to obtain the above effect, and 5.25% by weight When used in excess of, since skin irritation may occur due to excessive additives, it is preferably used within the above-described weight range.

The additive may include at least one or more of a water-soluble additive and an oil-soluble additive, and the water-soluble additive may include at least one or more of adenosine, arbutin, and niacinamide, and an oil-soluble additive Includes at least any one or more selected from the group consisting of retinol, retinyl palmitate, or mixtures thereof.

Among the water-soluble additives, arbutin should be included in at least 2 to 5% by weight to minimize skin irritation and exhibit a whitening effect. Therefore, when arbutin is used alone, it is preferably included in 2 to 5% by weight.

As such an additive, a mixture of adenosine and niacinamide is particularly preferably used, and the reason is as follows.

First, adenosine is a substance that is safe for the human body that exists in cells. It has the effect of improving skin troubles, conditioning effects and wrinkles due to the immune enhancing effect, and has excellent stability and lasting power when penetrating into the skin, and has strong resistance to oxygen or ultraviolet rays. It has the advantage of being able to use it without being restricted by the environment.

In addition, niacinamide improves oily troubled skin and promotes collagen secretion to prevent skin aging and has excellent whitening effect.

Therefore, when adenosine and niacinamide are used together, effects such as trouble skin improvement, conditioning, wrinkle improvement, whitening, and antioxidant can be obtained, and the resistance to oxygen or ultraviolet rays is strong, so that it can be used in various environments.

The emulsifier is added so that the water phase component and the oil phase component contained in the cosmetic composition can be mixed with each other. In particular, PEG-60 Hydrogenated Caster to stably and uniformly mix the shape restorer and the oil phase component in the water phase component. It is preferable to use a mixture of oil (PEG-60 hydrogenated caster oil) and polyglyceryl-3methtlglucose distearate in a weight ratio of 1:2.5-4.

The emulsifier is preferably used in a weight range of 0.5 to 5.1% by weight.If it is used in an amount of less than 0.5% by weight, the emulsification of the ingredients occurs unstable, and if it exceeds 5.1% by weight, skin troubles due to an excessive amount of emulsifier. , Allergies, etc. may occur.

On the other hand, the shape restorer is added to give the cosmetic composition the ability to restore the shape to return to the original shape even if the shape of the cosmetic composition changes due to external impact.The shape restorer is added to make the cosmetic composition unevenly on the skin. Even if applied, it is uniformly distributed due to its shape restoration ability, and in this process, the skin wrinkles are immediately spread out and elasticity can be given to the skin.

In addition, after taking the cosmetic composition contained in the container using a spatula or hand, the surface of the cosmetic composition changes flat by the shape restoration function after a predetermined period of time, so that even if it is used several times, it is possible to use it without being messy.

As such a shape restorer, PEG-240/HDI copolymer bis-decyltetradeceth-20ether is used. The shape restoration agent may be included in the cosmetic composition in an amount of 0.3 to 3.1% by weight.If it is used in an amount of less than 0.3% by weight, the above-described shape restoration performance is insignificant, and if it exceeds 3.1% by weight, the application property decreases due to excessive increase. This is because there is a problem that the emulsification of the shape restorer is uneven.

The thickener is added to increase the viscosity of the cosmetic composition to form a cosmetic formulation, improve spreadability, and improve adhesion, and may be used in an amount of 0.1 to 1.9% by weight. When the thickener is used in an amount of less than 0.1% by weight, it is difficult to obtain the above effect, and when it is used in excess of 1.9% by weight, there is a problem that the feeling of use is rather deteriorated due to excessive viscosity increase. It is desirable.

As such a thickener, it is preferable to use a mixture of sodium polyacrylate, hydroxypropylmethylcellulose, and ammonium acryloyldimethyltaurate/VP copolymer (Ammonium acryloyldimethyltaurate/VP copolymer).

Sodium polyacrylate not only increases the viscosity, but also gives the cosmetic composition an elongated texture, so that the user can intuitively recognize that the cosmetic composition is effective in enhancing skin elasticity. However, when sodium polyacrylate is used alone as a thickening agent, there is a problem that the expression of the texture that is stretched by the shape restorer is insignificant.

Accordingly, by stabilizing the emulsified state by using hydroxypropylmethylcellulose together, it is possible to improve the problem of decreasing the degree of elongation due to the shape restoration agent, and at the same time, the shape restoration function of the shape restoration agent may be maintained.

Ammonium acryloyldimethyltaurate/VP copolymer exerts an excellent effect in increasing the viscosity of the aqueous phase component, and acts to prevent the evaporation of moisture from the skin by inducing a film formation.

When using sodium polyacrylate, hydroxypropylmethylcellulose and ammonium acryloyldimethyltaurate/VP copolymer as a thickener, the weight ratio of each component is preferably 1:0.5 to 0.7:0.2 to 0.5.

In particular, when the weight ratio of hydroxypropylmethylcellulose to sodium polyacrylate is less than 0.5, there is a problem that the degree of elongation decreases due to the shape restorer, and if it exceeds 0.7, the shape is restored due to excessive hydroxypropylmethylcellulose. Since there is a problem that the emulsion state of the agent becomes unstable, it is preferable to mix and use each thickener to satisfy the weight ratio described above.

More preferably, it is preferable to use a thickener so that the weight ratio of the shape restorer and the thickener is 1:0.4 to 0.6, because in this case, the shape restoration ability can be maximized without deteriorating stickiness or adhesion.

In addition to the above-described components, the cosmetic composition of the present invention includes preservatives such as 1,2-hexanediol and phenoxyethanol, and sequestering agents such as disodium EDTA-2Na. , Flavors, pigments, and other additional components may be further included, and when these additional components are included, the total content of the preferred additional components is 1 to 4% by weight.

On the other hand, another embodiment of the present invention relates to a method of manufacturing a cosmetic composition having the above-described stretched texture and shape restoration function. Each component used here is the same as described above, and therefore, a duplicate description is omitted.

The manufacturing method of the cosmetic composition comprises: a first aqueous phase component manufacturing step of preparing a first aqueous phase component by mixing purified water, a shape restorer, and a polyol;

A second aqueous phase component manufacturing step of preparing a second aqueous phase component by mixing a thickener with the first aqueous phase component;

An oily component manufacturing step of mixing an emulsifier and an oil-soluble moisturizing agent to prepare an oily component; And

It includes; a cosmetic composition manufacturing step of mixing the second water phase component and the oil phase component.

The shape restorer used here is PEG-240/HDI copolymer bis-decyltetradeceth-20ether. When a substance is emulsified, the emulsification is unstable, or it is easily aggregated with other ingredients, so that the function of the cosmetic composition cannot be sufficiently expressed. Thus, in the present invention, this problem is solved by mixing the shape restorer using a multi-step method.

More specifically, the step of preparing the first aqueous phase component in which the shape restorer is mixed includes a first mixing step of mixing the polyol and the shape restorer at 50 to 80°C; A second mixing step of mixing the mixture prepared in the first mixing step and purified water; by mixing in the order of; the shape restorer is first uniformly dispersed in the polyol and then mixed with purified water, so that the shape restorer is uniform in the first aqueous phase component. It can be stably dispersed and emulsified.

When a water-soluble additive such as adenosine, arbutin, niacinamide is included in the cosmetic composition, a step of mixing a water-soluble additive may be performed between the first mixing step and the second mixing step, and the water-soluble additive is mixed in this order. Problems such as deterioration of stability and unevenness may not occur.

The second aqueous phase component manufacturing step is a step of mixing a thickener with the first aqueous phase component prepared through the first aqueous phase component manufacturing step, increasing the viscosity of the first aqueous phase component to form a formulation of the cosmetic composition, and It helps to maintain a uniformly dispersed state of water-soluble additives.

In particular, when the thickener is added before the polyol and the shape restorer are mixed or is added at the same time, the dispersion of the shape restorer is not uniformly performed, and the subsequent emulsification may occur unstable, so the mixture of the polyol and the shape restorer It is preferable that this is done first and then the thickener is added.

Thickeners used in the second aqueous phase component manufacturing step, sodium polyacrylate, hydroxypropylmethylcellulose, and ammonium acryloyldimethyltaurate/VP copolymer (Ammonium acryloyldimethyltaurate/VP copolymer) If they are added at the same time, it is difficult to stabilize, so sodium polyacrylate, ammonium acryloyldimethyltaurate/VP copolymer (Ammonium acryloyldimethyltaurate) in order to maintain the formulation stability of the cosmetic composition and mix uniformly /VP copolymer) and hydroxypropylmethylcellulose (Hydroxypropylmethylcellulose) are preferably mixed sequentially.

That is, sodium polyacrylate was added to the first aqueous phase component and stirred for a predetermined time, and ammonium acryloyldimethyltaurate/VP copolymer (Ammonium acryloyldimethyltaurate/VP copolymer) was added thereto for a predetermined time. After stirring, it may be carried out in the order of finally adding hydroxypropylmethylcellulose (Hydroxypropylmethylcellulose) and stirring for a predetermined time.

In particular, when sodium polyacrylate is added later than the other two types of thickeners or when hydroxypropylmethylcellulose is introduced first, long-term formulation stability is deteriorated, or shape restoration ability and increased texture are stable. Since it is not expressed, it is preferable to mix the thickener in the order described above.

Meanwhile, the step of preparing the oily component is a step of mixing the oily components included in the cosmetic composition, and is a step of mixing an emulsifier and an oil-soluble moisturizer. If the cosmetic composition contains an oil-soluble additive, the oil-soluble additive may be mixed in this step.

The cosmetic composition manufacturing step is a step of preparing a cosmetic composition having a single formulation by uniformly mixing the previously prepared second aqueous phase component and the oil phase component, and can be performed by slowly adding and stirring the oil phase component to the second aqueous phase component. have.

When materials such as sequestering agents, preservatives, pigments, and fragrances are additionally added, they may be mixed with the previously prepared cosmetic composition by adding and stirring them after the preparation of the cosmetic composition.

The cosmetic composition having an elongated texture and shape restoration function prepared through the above steps does not cause agglomeration or non-uniform dispersion of the shape restoration agent and additives, and because the emulsification is made stable, the cosmetic composition has excellent stability, It has an elongated texture and has the effect of uniform application and restoration of the shape of the cosmetic composition contained in the container to the original shape by the shape restoration function.

Hereinafter, an embodiment of the present invention will be described. However, the scope of the present invention is not limited to the following preferred embodiments, and those skilled in the art may implement various modified forms of the contents described in the present specification within the scope of the present invention.

The composition was prepared.

[ Experimental example One]

Cosmetic Composition Test

The emulsion stability, shape restoration ability, and degree of elongation of the cosmetic compositions prepared in Example 1 and Comparative Examples 1 to 3 were tested, and the results are written in Table 2.

Emulsion stability is to determine whether the prepared cosmetic composition is stored in a constant temperature bath (0°C, 45°C) and room temperature, and the emulsified state remains stable after 1 month, 2 months, 4 months, and 8 months and no phase separation or component separation occurs. It was observed with the naked eye, and it was checked whether the formulation with the elongated texture and shape restoration ability was maintained, and if it was stable and no phase separation or component separation occurred, and the elongated texture and shape restoration ability was maintained, it was good, unstable or phase separation, component separation. It was evaluated as a defect if the occurrence of or did not show the ability to restore the texture or shape.

The ability to restore shape is to fill 2/3 of the cosmetic composition in a container with a diameter of 6 cm and a depth of 3 cm, make the surface flat, take a part of the cosmetic composition using a spatula, and seal the container at room temperature for 2 hours. After leaving it to stand, observe the surface of the cosmetic composition contained in the container.If the surface is completely flat, O, △ if the spatula marks remain, and X if the spatula marks remain. And the shape restoration ability was measured.

As for the degree of stretching, 1 g of the cosmetic composition was placed on the thumb, and the length of the cosmetic composition was measured when the cosmetic composition was stretched using the middle finger, and the length of the cosmetic composition was not stretched, and the average value measured five times per each cosmetic composition is shown in Table 2.

Item Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Emulsion stability (0℃) 1 month Good Good Good Good Good 2 months Good Good Good Good Good 4 months Good Good Bad Good Good 8 months Good Good Bad Good Good Emulsion stability (45℃) 1 month Good Good Bad Good Good 2 months Good Good Bad Good Bad 4 months Good Bad Bad Bad Bad 8 months Good Bad Bad Bad Bad Emulsification stability (room temperature) 1 month Good Good Good Good Good 2 months Good Good Good Good Good 4 months Good Good Bad Good Good 8 months Good Bad Bad Good Bad Shape restoration ability O △ X △ O Increased length 6 cm 4 cm 3 cm 2 cm 4 cm

Referring to the experimental results in Table 2, in the case of Example 1, it was confirmed that the emulsion stability was consistently good regardless of temperature. In the case of Comparative Example 1, the stability at low temperature was good, but the emulsion was unstable at high temperature and room temperature, and thus long-term stability was poor.In the case of Comparative Example 2, only short-term stability at low temperature and room temperature was good, and long-term stability and The stability at high temperatures was found to be very poor.

In the case of Comparative Example 3, stability at low temperature and room temperature was found to be good, but when stored for a long time at high temperature, phase separation occurred, and even if re-emulsified through stirring, the property of stretching and shape restoration were not exhibited, so long-term stability at high temperature was achieved. It was found to be poor.

In the case of Comparative Example 4, stability at low temperature and short-term stability at room temperature were good, but when stored for a long time at room temperature and high temperature, phase separation did not occur, but long-term stability at high temperature and room temperature due to the fact that the stretching property and formation restoration ability were not expressed. It was found to be poor.

In terms of shape restoration ability, in the case of Example 1 and Comparative Example 4, the spatula marks disappeared within 2 hours, but in the case of Comparative Example 2, the spatula marks remain as they are after 2 hours, indicating that the shape restoration ability is poor. This is considered to be a problem caused by the inability to achieve stable and uniform emulsification and dispersion of the shape restorer because each component included in the aqueous phase component was mixed and stirred at the same time when the aqueous phase component was prepared. In addition, for the same reason, it is judged that the elongated length of Comparative Example 2 was insignificant compared to other cosmetic compositions.

In the case of Comparative Example 1 and Comparative Example 3, although the shape restoration ability was shown, it was found to be insignificant compared to Example 1.

Therefore, stability, shape restoration ability, and expression of increased texture vary depending on the timing of injection of the shape restoration agent and the order of addition of the thickener, so short-term and long-term stability at low temperature, room temperature, and high temperature are excellent, and shape restoration ability is excellent. And, it was confirmed that it is most preferable to prepare a cosmetic composition using the method of Preparation Example 1 in order to prepare a cosmetic composition of a formulation in which the stretched texture is sufficiently expressed.

Sensory evaluation

After allowing 20 women aged 20 to 40 to use the cosmetic composition of Example 1 and Comparative Examples 1 to 4, the skin adhesion, stickiness, and immediate wrinkle improvement effect were evaluated at 5 points (excellent). A score between 0 points (defective) was given, and the results were summarized and shown in Table 3.

Item Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Skin fit 4.7 3.9 2.7 4.1 2.8 Stickiness 4.5 4.2 3.5 3.6 4.3 Immediate wrinkle improvement effect 4.8 3.7 2.2 4.0 3.9 Average 4.7 3.9 2.8 3.9 3.7

Looking at the experimental results in Table 3, it was found that the cosmetic composition of Example 1 received the highest score in the score and average score for each item. Comparative Example 1 was evaluated that the feeling of use was good because of low stickiness, but the wrinkle improvement effect and skin adhesion were somewhat insufficient, and Comparative Example 2 was evaluated that the feeling of adhesion was somewhat insufficient and the immediate wrinkle improvement effect was insignificant.

Comparative Example 3 was evaluated to have good skin adhesion and immediate wrinkle improvement effect to some extent, but it was evaluated that the stickiness was somewhat severe and the feeling of use was inferior, and Comparative Example 4 had little stickiness but was evaluated as having poor skin adhesion. .

From the result of the sensory evaluation, the cosmetic composition of Example 1 prepared using the method of Preparation Example 1 having an elongated texture and shape restoration ability has excellent feeling of use, excellent skin adhesion, and immediate wrinkle improvement with a non-sticky texture. It was confirmed that the effect was excellent.

[ Experimental example 2]

A cosmetic composition was prepared by using the same method as in Preparation Example 1, but the content ratio of the thickener to the shape restoration agent was changed as shown in Table 4 below. At this time, sodium polyacrylate, hydroxypropylmethylcellulose, and ammonium acryloyldimethyltaurate/VPCopolymer were used in a weight ratio of 3:2:1 as a thickener.

Thereafter, the shape restoration ability performed in Experimental Example 1 was measured using the prepared cosmetic composition, and sensory evaluation was performed on the skin adhesion, the degree of stickiness, and the immediate wrinkle improvement effect, and the results are also described in Table 4.

Referring to the experimental results in Table 4, Examples 2 to 4 were found to have excellent shape restoration ability, and as a result of sensory evaluation, it was evaluated that skin adhesion, stickiness, and immediate wrinkle improvement effect were excellent.

In the case of Comparative Example 5, it was evaluated that the shape restoration ability was excellent, but the viscosity was excessively low, and the skin adhesion was bad, and accordingly, it was evaluated that the immediate wrinkle improvement effect did not appear. In the case of Comparative Example 6 and Comparative Example 7, the shape restoration ability was also poor, and the sensory evaluation result in each item was not good, so it was confirmed that the user's preference was low.

Therefore, from the results of this experiment, when the shape restoration agent and the thickener are mixed so as to have a weight ratio of 1:0.4 to 0.6, a cosmetic composition having excellent shape restoration ability, excellent skin adhesion, no stickiness and excellent immediate wrinkle improvement effect is obtained. It could be confirmed that it could be.

[ Experimental example 3]

A cosmetic composition was prepared using the same method as in Preparation Example 1, but the contents of sodium polyacrylate, hydroxypropylmethylcellulose and ammonium acryloyldimethyltaurate/VPcopolymer used as thickeners were changed as shown in Table 5 below. A cosmetic composition was prepared, and the shape restoration ability and lengthened length of each cosmetic composition were measured and described together in Table 5.

Referring to the results of Table 5, as thickeners, sodium polyacrylate, hydroxypropylmethylcellulose, and ammonium acryloyldimethyltaurate/Vpicopolymer are included, and the weight ratio of sodium polyacrylate and hydroxypropylmethylcellulose is In the case of Examples 5 to 7 of 1:0.5 to 0.7, it was confirmed that the shape restoration ability was also excellent, and the increased length and emulsion stability at room temperature were good.

On the other hand, in Comparative Examples 8 to 10, it was confirmed that the elongated length of the cosmetic composition was insignificant, and the emulsion stability at room temperature was poor. Comparative Example 11 was found to have good elongated length but poor emulsion stability.

In the case of Comparative Example 8 and Comparative Example 9, it was judged as the result shown because only one thickener of sodium polyacrylate and hydroxypropylmethylcellulose was used, and in the case of Comparative Example 10, hydroxypropylmethyl for sodium polyacrylate It is judged as the result shown because the content of cellulose was too small to compensate for the decrease in the expression of the elongated properties of sodium polyacrylate by the shape restorer. In the case of Comparative Example 11, compared to sodium polyacrylate, hydroxypropylmethylcellulose It is judged as the result shown because the content was excessive and the emulsion stability was lowered.

Therefore, from the results of this experiment, sodium polyacrylate, hydroxypropylmethylcellulose, and ammonium acryloyldimethyltaurate/Vpicopolymer were used as thickeners, but the weight ratio of sodium polyacrylate and hydroxypropylmethylcellulose was 1 : When used so as to be 0.5 to 0.7, it was confirmed that the emulsion stability was excellent, and the stretching properties of sodium polyacrylate were fully expressed.
