Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic composition for improving skin elasticity and improving skin wrinkles in a short time,

The present invention relates to a cosmetic composition for enhancing skin elasticity and improving wrinkles of skin comprising modified natural corn starch derived from natural and safe skin, and more particularly to a cosmetic composition for enhancing skin elasticity and skin wrinkle of the present invention Include betaine, ethanol, phenoxyethanol, ethylhexyl glycerin, solubilizing agent, grapefruit extract, horsetail extract and safflower extract.

It gives the elasticity to the stretched skin by filling the fine wrinkles on the skin and gives strong skin shrinking effect, and its physical elasticity leads to the effect of improving wrinkles. And skin wrinkle-improving effect.

In the cosmetics industry, efforts have been made to prevent and improve symptoms that interfere with people seeking extrovert beauty, such as dryness, loss of elasticity, wrinkles, spots and freckles. The causes of these symptoms can be divided into three main causes, which are affected by genes inherited from parents as a genetic factor. The second is the movement of the muscles according to the facial expressions, which occurs naturally when humans laugh or frown, and can result in the generation of wrinkles by constantly applying certain forces over time. The third cause is wrinkles and skin burns caused by an increase in collagen, elastin, and matrix metalloproteinases (MMPs), which account for most of the skin's dermis. The main reason for the increase in the amount of MMP is due to UV. Ironically, humans are always exposed to UV. This causes the wrinkles to increase continuously and the elasticity of the skin to gradually decrease. Humans have turned to functional cosmetics to improve their wrinkles and elasticity, and there is already a big market around the world. Research and development of cosmetics capable of improving skin wrinkles and improving skin elasticity have been continuously carried out. Functional cosmetics for improving skin wrinkles containing a phosphorus-containing substance as an active ingredient No. 10-2011-0138116), a functional cosmetic for improving skin wrinkles (Korean Patent Laid-Open No. 10-2011-0131822) containing a phosphoric acid contained in a fermented green tea extract as an active ingredient, and a peppermint extract (Korean Patent Laid-Open Publication No. 10-2011-0131820), a cosmetic composition for improving skin wrinkles containing an active ingredient of processed ginseng extract (Korean Patent Laid- 10-2011-0131784), a composition for improving skin condition comprising human placental lactogene as an active ingredient Cosmetics such as skin moisturizing and elasticity cosmetic composition containing kelp extract, seaweed extract and tea extract (Korean Patent Laid-Open Publication No. 10-2011-0118497) have been steadily developed There is a trend.

However, in the case of the cosmetic compositions disclosed in the above-mentioned patent publications, a visible effect is obtained only when the product is used for at least 3 months in order to see the effect of improving the wrinkle and elasticity. On the contrary, . In order to satisfy these consumers, there is a market for elasticity and wrinkle improvement products that can be used in a short period of time by using silicone or synthetic polymer. However, as a cosmetic composition utilizing raw materials derived from nature, Products are difficult to find.

Example

Example 1: Cosmetic composition for improving skin elasticity and improving skin wrinkles

Example 1-1: Preparation of cosmetic composition containing skin shrinkage-modified corn starch

The present invention relates to a cosmetic composition for enhancing skin elasticity and improving wrinkles of skin, comprising a skin-shrinkage-modified corn starch derived from natural, skin-safe natural skin to form a film on the skin to improve skin elasticity and improve skin wrinkles,

40 to 98.49% by weight of a skin shrinkage-modified corn starch dissection comprising 0.5 to 10% by weight of the skin shrinkage-modified corn starch; 0.5 to 10% by weight; 0.5 to 25% by weight of the solubilized portion; And a physiologically active portion of 0.01 to 25% by weight; .

When the cosmetic composition for skin elasticity enhancement and skin wrinkle improvement is applied to the skin, the viscous gel fills the deep wrinkles of the skin, forms a film on the skin surface, and pulls the wrinkles between the skin by strong shrinkage. This phenomenon occurs very quickly, usually between one and two minutes after application of the skin, and lasts for two to three hours.

Herein, the cosmetic composition for enhancing skin elasticity and improving skin wrinkles forms a film within a short period of time upon application to the skin to maximize physical elasticity, thereby enhancing skin elasticity and improving skin wrinkles. Using corn starch, solubilizing agent and physiologically active ingredient, it increases the duration of physical force, and it is felt tactile after application to the skin, and the duration is maintained for a long time to improve the deep wrinkles of the skin and restore skin elasticity .

In the present invention, the present inventors developed a product having an effect of improving skin elasticity and wrinkle through physical pulling effect immediately upon application. The biggest disadvantage of many products for conventional elasticity enhancement and wrinkle improvement is that they should be used on a daily basis and their use is at least 3 to 6 months old. This can be interpreted as a long period of time for the material to be effective since the materials used for wrinkle and elasticity improvement were mostly physiochemical. The problem, however, is that the majority of consumers are hoping that if they apply cosmetics, their effects will be visible in a short period of time. In order to obtain the effect in a short period of time after using the cosmetic material, a physical force other than a physiochemical substance is required. In the present invention, the physical force is used as the most important technique. Usually, the physiological chemical substances used in cosmetics for improving elasticity and wrinkles cause various reactions when they penetrate into the skin. However, the skin shrinkage-modified corn starch used in the present invention is a film which, when applied to the skin, And it has an effect of pulling the creases between the skin by strong contraction. This occurs very quickly, usually between 1 and 2 minutes after application to the skin, and lasts for 2 to 3 hours. Therefore, the present invention can achieve a visible effect within a short period of time by using a physical force which was not seen in many products which had a conventional elasticity and skin improving effect, and can meet the desire of a consumer who wants a quick effect.

The cosmetic composition for enhancing skin elasticity and improving skin wrinkles maintains a gel phase at room temperature and low temperature, and is viscous. Therefore, it can be applied evenly on skin without flowing when used. After applying the skin, the viscous gel fills deep wrinkles and forms a film on the skin in a short time, resulting in a physical pulling effect. The film imparts elasticity to the stretched skin and has strong skin shrinking effect, Leading to improvement.

In addition, the cosmetic composition for enhancing skin elasticity and improving skin wrinkles quickly forms a film having excellent relaxation skin contracting power due to binding force of starch by hydrogen bonding, and the drying speed of the film is controlled by a water-soluble humectant, And by this, the physical force generated thereby exhibits a quick skin elasticity enhancement and wrinkle improvement effect.

At this time, the skin shrinkage-modified corn starch may be selected from the group consisting of sodium magnesium silicate, xanthan gum, hydroxypropyl starch phosphate, polyurethane-2, (Polymethyl Methacrylate), PVP polymer, or a mixture of two or more thereof.

When the skin shrinkage-modified corn starch is applied on the skin, a film is formed on the skin, resulting in a skin elasticity effect within a short time, and is very effective for alleviating a wide and deep wrinkles.

When the content of the skin shrinkage-modified corn starch is less than the above range, it is difficult to form a shrink film when it is applied onto the skin. When the content of the skin shrinkage-modified corn starch exceeds the above range, it is difficult to dissolve properly, But after a certain period of time, dense corn starch aggregation occurs.

In addition, the solubilizing portion includes ethanol, phenoxyethanol, ethylhexyl glycerin, preservative or perfume.

The ethanol is used as a solvent for homogenizing preservatives and perfumes that are not soluble in water, such as phenoxyethanol and ethylhexyl glycerin. When the content of ethanol, phenoxyethanol, and ethylhexyl glycerin is less than the above range, it is difficult to uniformly blend the preservative and the fragrance. When the content of ethanol, phenoxyethanol, and ethylhexyl glycerin exceeds the above range, There arises a problem that the solubility of corn starch is lowered and the film formation is hindered.

The physiologically active portion may be selected from the group consisting of plant extracts including aloe extract, grapefruit peel extract, march extract, chamomile extract, safflower extract, jelly mulberry seed extract, elm root extract, pipermetic stercible / root / stem extract, , Arbutin, vitamin B3, vitamin B5, vitamin B9, vitamin C, soluble vitamins and derivatives of vitamin H, acetylglutamine, acetylglucosamine, Centella asiatica extract including maddicoside, carnosine or various Peptide components, or a mixture of two or more thereof.

The physiologically active ingredient constituting the physiologically active part is mainly a liquid or a water-soluble powder ingredient, and is composed of materials having excellent skin-improving effect.

When the content of the physiologically active moiety is less than the above range, substantial skin improving effect is insufficient. When the content of the physiologically active moiety exceeds the above range, the skin-shrinkage-modified corn There arises a problem that the solubility of the starch is lowered.

The cosmetic composition for enhancing skin elasticity and improving skin wrinkles may further comprise 0.5 to 30 parts by weight of a moisturizing component based on 100 parts by weight of the cosmetic composition for enhancing skin elasticity and improving skin wrinkles.

The moisturizing component may be any one of glycerin, butylene glycol, propylene glycol, sorbitol, hexylene glycol, dipropylene glycol, diglycerin, 1,2-hexanediol, panthenol, betaine or hydrolized wheat proteins, Two or more mixtures.

If the content of the moisturizing moiety is less than the above range, the skin may become dry. If the content of the moisturizing moiety exceeds the above range, film formation is difficult or shrinkage is delayed.

At this time, the cosmetic composition for improving skin elasticity and wrinkles of skin is composed of modified corn starch having a physical skin shrinking effect and a physiological active part which is a natural moisturizing factor maximizing its effect, a solubilizing part and a moisturizing part for maintaining the moisturizing power Thus, skin elasticity effect and wrinkle improvement effect are exhibited within a short time.

The cosmetic composition for enhancing skin elasticity and improving skin wrinkles may be an ointment, a cream, a lotion, a pack, and a spray or mist formulation having a low viscosity.

The present invention also relates to a cosmetic composition for improving skin elasticity and improving skin wrinkles, which comprises a skin-shrinkage-modified corn starch derived from natural, In the production method,

The method for manufacturing a cosmetic composition for enhancing skin elasticity and improving skin wrinkles,

Herein, the method for manufacturing a cosmetic composition for enhancing skin elasticity and improving skin wrinkles includes a method of uniformly dissolving the skin shrinkage-modified corn starch having physical skin shrinking effect and a physiologically active portion that is a natural moisturizing factor maximizing its effect, , It forms a film on the skin in a short time during the application of the skin to maximize the physical elasticity, thereby exhibiting a strong skin shrinking effect that promotes skin elasticity and improvement of skin wrinkles, thereby exhibiting skin elasticity effect and wrinkle improvement effect in a short time.

At this time, the method of manufacturing a cosmetic composition for enhancing skin elasticity and improving skin wrinkles is characterized in that the skin shrinkage-modified corn starch is completely dissolved in purified water to form a skin shrinkage-modified corn starch dissolution part, and the skin shrinkage- To disperse and dissolve the thickening agent so as to form viscous gel phase of the skin shrinkage-modified corn starch-dissolving part. The thickener may be selected from the group consisting of sodium magnesium silicate, xanthan gum, hydroxypropyl starch phosphate, polyurethane-2, polymethyl methacrylate ), PVP polymer, or a mixture of two or more thereof.

Next, phenoxyethanol and ethylhexyl glycerin were added to the viscous gel by dissolving the preservative and fragrance in ethanol.

From the analysis results of Table 1, the following facts were confirmed.

In the case of Examples 1 and 2, the AGI process was performed at about 35 ° C to 45 ° C so that it was very well dissolved and homogenized.

As shown in Table 1, up to 10% by weight of the skin shrinkage-modified corn starch was easily dissolved and homogenized, and the physical strength to be pulled on the skin was appropriate.

However, if the content of the skin shrinkage polymer exceeds 10% by weight as in Comparative Example 6, there arises a serious problem in dissolution and stabilization. It takes much time to dissolve even at a temperature of 45 ° C or higher, After one week, the skin-shrinkage-modified corn starch did not dissolve completely, resulting in uneven texture and unstable texture. When applied to the skin, the film was rapidly formed on the skin and hardened to hard to use as cosmetics.

In Comparative Example 4, after the application of the cosmetic material, the content of alcohol used to increase the rate of shrinkage of the skin shrinkage-modified corn starch by increasing the volatilization rate of the cosmetic material was 30.0% by weight and the adverse effect was adversely effected and the solubility was very poor. The precipitation of degenerated corn starch has caused a lingering phenomenon. In addition, the viscosity-forming ability of the thickening agent was remarkably decreased, so that a stable gel phase could not be formed.

In Comparative Example 5, a physiologically active ingredient was applied in a high content of 30% or more. In this case, the water in the water portion was sharply reduced, and it was difficult to dissolve the skin shrinkage-modified corn starch.

In order to examine the effect as a practical cosmetic, the cosmetic obtained from Example 2 was applied on the skin and the eye area was measured using a digital camera (NIKKON DS-350) to confirm the visual effect. The application area was observed to spread from about 90 seconds after the application, and the pulling of the deep wrinkle was also shown in FIG.

Example 2 The skin elasticity was measured before applying with the cosmetic composition obtained from the composition of Comparative Example 1 as a control group and after 30 minutes of application using a cutometer (Model: MPA 580, CK Electronic, Germany) 2. The elasticity of the skin is expressed as the skin elasticity is better when the device is pulled back and forth, and when it is repeated, the skin elasticity is better when the value is closer to '1', and the skin elasticity is worse when it is closer to '0'. As shown in FIG. 2, the elasticity values before use were 0.64 / 0.60, respectively. When the cosmetic obtained from Example 1 was used, it was 0.86 immediately after use and increased by about 30.4%. In Comparative Example 1, As described above, it has been found that a film is formed on the skin to give a strong pulling effect to the skin, and an excellent skin elasticity is improved in a short time.

The wrinkle depth and width were also measured using a Visiometer (Model MPA 580, CK Electronic, Germany) to evaluate the effect of wrinkles. This method of measuring the replica of the skin allows the light to pass through the device, which can be calculated by the equation to calculate the depth and width of the wrinkle freely within the range specified by the user. The measured value is measured by the distance value R2 between the highest point and the lowest point when dividing the measurement part into five parts, so that the change of the wrinkle can be confirmed numerically.

For the two subjects, the application of the cosmetic material obtained from Example 1 was performed on the right and left eyes, and the wrinkles before application and after 90 seconds of application were measured using a Violet meter. As shown in FIG. 3, the wrinkle measurement R2 value before use was 97.48 on the left side and 99.78 on the right side for the subject 1, and 113.7 and 70.92 on the left side for the subject 2, respectively. After the cosmetic obtained from Example 1 was applied to both eyes of two subjects, the eye wrinkles were re-measured after 90 seconds. As a result, the R2 value was 44.09 on the left side and 37.08 on the right side for the subject 1, and 44.71 and 67.02 on the left side for the subject 2. Thus, the cosmetic obtained from Example 1 showed a significant mitigation effect of about 49.5% in 90 seconds of use.

Accordingly, the present invention is a cosmetic product using skin-shrinkage-modified corn starch which is safe for skin forming a film on the skin and has a very excellent effect for alleviating deep skin elasticity effect and deep wrinkle in a short time within 2 minutes .
