Composition having cooling effect for scrub or body-cleansing}

The present invention relates to scrubs and / or body cleansing products having a cold heat effect in use.

Sugar alcohols include erythritol, xylitol, sorbitol, mannitol, maltitol, hydrogenated starch hydrolysate, and functional saccharides having a molecular structure in which aldehyde groups of common sugars such as glucose, maltose and xylose are reduced with alcohol groups. It is currently being used as a substitute sweetener.

In general, sugar alcohols do not have free carbonyl groups and thus do not cause maillard degeneration, are more stable to heat than other monosaccharides and disaccharides, are not easily decomposed by microorganisms, and have high endothermic properties in solution. Such sugar alcohols are mainly used as an alternative sweetener of sugar in various fields such as hard tooth decay, low calorie functional foods and pharmaceuticals.

In particular, many studies have been conducted on applying sugar alcohols to foods, and there are many known functions for improving the degree of crystallization, shape retention, stability, viscosity, texture, solubility, shelf life, and water retention. In addition, the sugar alcohol has a high heat of dissolution has the effect of providing a cool refreshing feeling in the mouth.

In general, pack compositions that give skin a sense of warmth have been used in pack formulations or applied to scrub products. The thermal pack composition includes gypsum, anhydrous salt, or anhydrous oxide as an active ingredient that reacts with water to cause an exothermic reaction. Such a heat pack composition is treated on the skin to give a warm feeling to the skin to help promote blood circulation and effective skin penetration and contaminant removal.

In addition, in order to exhibit effects such as soothing the skin, shrinking pores, improving wrinkles, and soothing skin images by exposure to sunlight, it is necessary to impart a cooling effect to the skin.

The pasta or cosmetics conventionally used to give the skin a cool feeling contains a small amount of menthol, sorbitol, peppermint oil, etc., which gives a refreshing feeling to the skin, but does not lower the temperature of the actual skin, It is known to cause severe irritation.

Therefore, the technical problem to be achieved by the present invention is to provide a scrub and / or body cleansing products that not only have no skin irritation, but also provides a cooling effect on the skin.

In order to achieve the above technical problem, it provides a scrub or body cleaning composition having a cold heat effect characterized in that it comprises a sugar alcohol that causes an endothermic reaction when dissolved in water.

More preferably, the present invention provides a scrub or body cleansing composition having a cold heat effect, wherein the sugar alcohol is any one or more selected from the group consisting of erythritol, xylitol, sorbitol, mannitol, paratinose, maltitol and lactitol. .

More preferably, the present invention provides a scrub or body cleaning composition having a cold heat effect, wherein the sugar alcohol is included in an amount of 25 to 90% by weight based on the total weight of the composition.

According to the present invention, when a sugar alcohol is contained in a scrub and / or a cleaning product, the sugar alcohol is dissolved by water remaining in the skin when washing or showering to impart a more effective cooling effect, and at the same time, skin irritation and smell It is based on the surprising discovery that it is possible to provide a safe scrub and / or cleansing product to the skin without a back. The scrub and / or cleaning compositions according to the invention may be compositions of non-aqueous and / or general emulsion formulations with a cold effect.

Hereinafter, the scrub and / or cleaning composition of the present invention will be described in more detail.

The inventors of the present invention while researching a product that is safe for the skin and excellent in the effect of cooling, paying attention to the high heat of dissolution of sugar alcohol and applying the sugar alcohol to the cosmetics of various formulations, as a result, can effectively give the cooling effect, at the same time skin safety, Not only does the smell and the like have no problems, but also the surprising fact that the sugar alcohol particles are very effective in imparting a physical scrub effect, and the present invention has been completed based on this.

The scrub and / or cleaning product having a cold heat effect of the present invention is characterized by including a sugar alcohol as a coolant.

The sugar alcohols used in the present invention can be used as long as the functional saccharides having the molecular structure in which the aldehyde group of the general saccharide is reduced to the alcohol group. Specifically, the sugar alcohol may be erythritol, xylitol, sorbitol, mannitol, paratinose, maltitol, lactitol and the like, but is not limited thereto. In particular, it is preferable to apply erythritol, xylitol, sorbitol or mannitol with high heat of dissolution in order to give a strong cooling effect when applied to the skin. For reference, the heat of dissolution of the sugar alcohol is shown in Table 1 below.

Kinds Melting heat (Kcal / kg) Erythritol -42.9 Xylitol -36.6 Sorbitol -26.5 Mannitol -28.9 Paratinos -14.3 Maltitol -5.5 Lactitol -9.4

The sugar alcohol is preferably included 20 to 90% by weight, more preferably 30 to 70% by weight relative to the total weight of the cosmetic composition. If the content is less than 20% by weight, there is a problem in that the cooling effect is weak, when it exceeds 90% by weight there is a problem that the formulation and stabilization of the formulation as a cosmetic composition is difficult.

In general, the particle size of the commercially available sugar alcohol is 0.1 ~ 1.5mm can feel a proper scrub feeling, it can be slowly dissolved to provide a refreshing and cooling effect on the skin. In addition, when finely pulverized these particles to prepare and apply a powder of 10nm ~ 0.1mm, it is possible to obtain a high dissolution rate in accordance with the increase of the surface area can provide a higher refreshing feeling and cooling effect, while If the particle size is 0.7 ~ 1.5 mm has the advantage that the scrub effect is increased.

Therefore, the particle size of the sugar alcohol is preferably 0.7 ~ 1.5 mm in the case of products with more emphasis on the scrub effect, the particle size of the sugar alcohol is preferably 10nm ~ 0.1mm in the case of products with emphasis on cooling and cooling effect. . That is, the scrub effect and the degree of refreshing feeling can be differentiated by adjusting the blending ratio according to the total amount, particle size and particle size of these active ingredients. Therefore, in addition to the scrub composition, it is also possible to provide a human detergent containing only a finely ground sugar alcohol.

The scrub and / or cleaning composition of the present invention comprising the above-mentioned sugar alcohol as a coolant may further include an oil component, a dispersant, a fatty alcohol, a sunscreen, and the like, which are used in a conventional cosmetic composition in addition to the sugar alcohol, and may be necessary. According to the conventional cosmetic composition may further include additives such as perfumes, preservatives, surfactants.

It is preferable to commercialize the sugar alcohol in a non-hand-made form containing no water, in a powder form obtained by pulverizing the particles or these particles, or by mixing the sugar alcohol in a general formulation using water supersaturated with these sugar alcohols.

Accordingly, the present invention also includes a scrub or body cleansing composition having a cold heat effect, or a sugar alcohol particle or powder suspended in water supersaturated with sugar alcohol, characterized in that it comprises a non-hydrophilic cosmetic base containing sugar alcohol particles or powder. It provides a scrub or body cleansing composition having a cooling effect.

As shown in Table 4, the cold scrub products of Examples 1 to 8 according to the present invention can be seen that the temperature is lowered to 10 ℃. In particular, it was confirmed that the temperature reached a lower temperature than in the case of using the smaller particles of 0.3 to 0.7 mm ziitol and erythritol.

Experimental Example 2

The feeling of usability of the products of Examples 1 to 8 and Comparative Examples 1 and 2 was evaluated for 20 women aged 25 to 40 years. Each product was run on the treadmill for 20 minutes under the same conditions, and then showered with water at 35 ° C. for 3 minutes, and then 20g of the product was applied to the whole body for 1 minute to evaluate the feeling of use. Feeling was evaluated by repeating the method. The evaluation was conducted in three stages: strong refreshment, refreshing, and no refreshing. The results are shown in Table 5.

As shown in Table 5, the cold scrub products of Examples 1 to 8 according to the present invention showed a cool refreshing feeling in 85% or more of the test subjects. In addition, it was found that the side effects such as skin irritation and rash did not occur at all in the process of evaluating the products of Examples 1 to 8, which is a very safe composition.

On the other hand, it is possible to increase the amount of the cold heat effective ingredient or to provide a stronger refreshing feeling than when xylitol or erythritol, which is more finely powdered, is mixed with existing particles.

Experimental Example 3

The exfoliation effect was evaluated about the product of Examples 1-8 and Comparative Examples 1-2 as follows. Before applying the sample to 30 healthy men and women aged 20-40 years, the color inside the upper arm of the subject was measured with a color meter (Dhroma meter, CR-200, Minolta, Japan). Four 2 cm test sites were colored brown for 6 hours with 10% dihydroxy acetone (DHA). Each sample was then applied to the colored area and rubbed for 2 minutes with the same force, followed by washing the sample with water. After washing the colored area, the color of the colored part after 60 minutes was measured to determine the color difference from before the sample application. Thereafter, after squeezing and washing for 2 minutes by the same method of coating the sample once a day, the color was measured and measured by the colorimeter to measure the degree of discoloration every day, and the time taken to return to the original skin color was shown in Table 6 below. .

Stratum corneum regeneration Example 1 10.8 Example 2 14.6 Example 3 11.5 Example 4 14.8 Comparative Example 1 11.3 Example 5 10.5 Example 6 15.1 Example 7 11.6 Example 8 14.6 Comparative Example 2 12.5

As shown in Table 6, Examples 2, 4, 6, and 8 have a particle size of 0.3-0.7 mm of zithritol or erythritol, and the cold feeling effect is excellent, but the exfoliation effect is insignificant as a scrub. However, in the case of Examples 1, 3, 5 and 7, it can be seen that it shows a level of exfoliation effect similar to the existing sugar particles can be used as a scrub agent. In particular, when xylitol or erythritol particles having better solubility than sugar were used as a scrubbing agent, it was found that the test subjects felt low irritation compared to sugar because of low tingling feeling.

In the above experimental example it can be seen that it is possible to provide an effective cooling and scrubbing effect by adjusting the composition according to the content and particles of zithritol or erythritol.

As such, the scrub and / or body cleansing composition having a cooling effect according to the present invention can obtain a physical scrub effect due to the sugar alcohol particles contained in the use, and these components are dissolved in water to cause an endothermic reaction, resulting in a refreshing feeling in use. And a cooling effect, and even when used in large amounts, there is no skin irritation.
