Description

[0001] Compositions for skin cooling and cleansing [

More particularly, the present invention relates to a composition for skin cooling and cleansing, which comprises 20 to 80% by weight of an aerosol stock solution and 20 to 80% by weight of an aerosol spray agent, wherein the aerosol stock solution contains alkanolamide as a cationic surfactant To 30% by weight of the composition and 0.1-0.5% by weight of the composition.

In general, products that show skin cooling and cooling effects contain menthol, its derivatives, or volatile components such as alcohol, so that many products can feel a refreshing feeling. In addition, there are some products that contain gas in the contents to give a cooling effect by the gas, and feel a refreshing feeling only after spraying in the form of spray. However, most of these products are non-washed skin products. For example, Korean Patent No. 100784238 discloses a cosmetic composition for skin cooling that gives a cooling sensation but is not a product to be cleansed by cleansing, but a product that absorbs skin, and can not simultaneously obtain a cooling function and a cleansing function. Korean Patent No. 100602144 discloses a cosmetic composition for skin moisturizing having a refreshing sensation containing talc and butane, but has a disadvantage in that it has a function of imparting a cooling sensation to the skin, but can not obtain a cleansing function at the same time.

In addition, in the case of an aerosol containing an injection gas, the use of the gas was limited due to the injection pressure of the gas, and the application to the cleanser was largely based on the above method. The cleaning components used for cleaning the foam were sprayed with the foam by the gas, which was not easy to obtain a feeling of cooling from the foam with a small amount of collected gas. Furthermore, there have been some developments in existing cleansers, but there has been no development of a cleansing cleanser, and there is a growing demand for these new products.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a slush composition such as snow, which is sprayed with a low boiling point spray agent and alkanolamide, The present invention provides a new cooling cleanser composition which can be foamed and cleansed while providing a cooling feeling and a pore-shrinking effect to the skin by the composition.

According to one aspect of the present invention, the present invention provides a cosmetic composition comprising 20-80% by weight of an aerosol stock solution and 20-80% by weight of an aerosol sprayer, wherein the aerosol stock solution comprises 1-30% by weight of alkanolamide which is a zwitterionic surfactant, And 0.1 to 0.5% by weight of an incrementing agent.

The composition of the present invention includes alkanolamide as an active ingredient for simultaneously imparting a cleansing effect together with skin cooling. Although it is known that the alkanolamides are one kind of zwitterionic surfactants, they have a property of bubbling. In the present invention, however, the function of collecting the injected gas is maximized while suppressing the generation of bubbles, So that a superior cooling effect is exhibited. Accordingly, the present invention was first discovered as a new function of the alkanolamide, that is, the effect of controlling the constellation during cooling and cooling effect, and the present invention was devised as a detergent for skin cooling.

Due to the above-mentioned effects, the composition of the present invention is advantageous in that it does not need to contain volatile components such as menthol and alcohols that have been used to counteract the conventional cooling feeling.

In the composition of the present invention, the alkanol amide is a compound obtained by a condensation reaction of a fatty acid and an alkanolamine, and has a structure represented by the following formula (1).

Here, RCO is a fatty acid group (fatty acid radical), X is a -CHR'CH ₂ OH group (R 'is H or Alkyl), Y is the same as H or Alkyl or Alkanol or X.

Suitable alkanolamides for use in the composition for both skin cooling and cleansing of the present invention are cocamide MEA (cocamide monoethanolamine), acetamide MEA, benenamide MEA, Aramide maei, lactamide maei, laura mide maei, linoleamide amaei, myristamide maei, octamide maei, oleamide maei, olive amide maei, palmamide maei, isosteara And the isomerase inhibitors of the present invention include, but are not limited to, the following compounds: milddehyde, almond amide dieh, apocotamide dieh, avocad amide dieh, cocamid dieh, behen amide dieh, This, Laura Maid, Deai, Miri And the like Tama Id di yieyi Num Ca Id di yieyi, oleic amide di yieyi, olive amide di yieyi, palm amide di yieyi. Preferably cocamide di-a, lauramide di-ai, or mixtures thereof. The alkanolamide is contained in an amount of 1-30% by weight based on the total weight of the aerosol stock solution contained in the composition, and when it is less than 1% by weight, it is foamed in a foam form instead of a sludge form, , The feeling of use and skin safety are deteriorated.

In the composition of the present invention, a liquefied gas commonly used in an aerosol container as the aerosol propellant can be selected and used. Specific examples thereof include liquefied petroleum gas (LPG), propane, n-butane, isobutane, and dimethyl ether May be used alone or in combination. The amount of the injecting agent used is 20-80% by weight, preferably 40-60% by weight based on the total weight of the composition. If it is less than 20% by weight, a desired effect can not be obtained. If it is more than 80% by weight, the injection pressure is too strong, resulting in fear of frostbite and contents.

In the composition of the present invention, the thickener is a component capable of increasing the viscosity of the stock solution, which improves the stability of the foam during mixing, and in particular, Stabilizing component. In order to achieve the above effect, the increment component may be contained in the range of 0.05-10.0 wt%, but it may be preferably 0.1-5.0 wt% in order to obtain the optimized effect. When the content is lower than the above-mentioned range, the viscosity of the mixture is low, so that it is difficult to stabilize the mixture of the content and the gas. When the content is higher than the above range, the content is difficult to produce.

The gradual ones that can be used in the composition of the present invention include everything classified as Gums, Hydrophilic Colloids and Derivatives, Synthetic Polymers in the Chemical Class of ICID (International Cosmetic Ingredient Dictionary). As a preferred example, the thickening agent may be selected from the group consisting of hydroxyethyl cellulose, carbomer, hydroxypropyl methylcellulose, hydroxypropyl cellulose, hydroxypropyl guar, and xanthan gum.

In addition, the composition of the present invention may contain optional ingredients known in the art such as ethylenediaminetetraacetate (EDTA), humectants, fatty substances, wetting agents The composition may further include ingredients conventionally used in the manufacture of skin cleansers such as substances, silicones, oils, fragrances, preservatives, transparent agents (sugar, alcohol), vitamins, proteins,

In addition, the composition of the present invention may also contain, in addition to the above components, an antioxidant, a skin conditioning component, a pH control component, a skin protective component, and an ultraviolet blocking component.

As described above, the present invention makes use of a low-boiling spraying agent and alkanolamide to form a cold composition upon spraying, which is effective in cleansing, cleansing, and removing makeup, It also has the effect of shrinking pores and calming the skin in summer.

As described above, the spray form and the usability of the detergent composition prepared according to Examples and Comparative Examples were confirmed.

As a result, as shown in FIG. 1, Examples 1 to 6, which were prepared with alkanolamide (cocoamide diether, Lauraidide), sprayed in a cold slush state at the time of spraying, A possible cooling detergent composition could be obtained. In particular, the compositions of Examples 1 and 2 containing only alkanolamide were sprayed in the coldest slush state, so that the cooling effect due to alkanolamide was excellent.

On the other hand, in Comparative Example 1, the cooling foam was not formed, and in Comparative Example 2, the injection pressure was too strong, so that the frost was caused by the gas, and the contents were blown and the usability was poor. In Comparative Examples 3 to 5, since the alkanolamide was not contained, the foam was foamed in a foam form rather than a slush form, the spraying gas could not be captured by the surfactant, and the cooling feeling was lowered. In Comparative Examples 6 to 7, when the content of the agglomerating agent was relatively large, a proper raw solution was not produced in the preparation of the aerosol stock solution, and in the case of no agglomerating agent, the undiluted solution and gas were not mixed, , And it was badly useless because of heavy swelling.

[ Experimental Example . skin Cooling  effect]

The skin cooling effect of the cooling detergent composition made according to Example 1 was tested. The subjects were 5 adults, pumped once, poured wide on the forearm of the test area, wiped off after massage, and skin temperature (℃) was measured at intervals of 1 minute (1m, 2m, 3m, 4m, 5m) Were measured. The results are shown in Table 3 and FIG.

Before use Immediately after use Immediately after polishing 1m 2m 3m 4m 5m Tester 1 32.03 0.30 20.15 21.30 26.60 27.90 29.70 30.90 Tester 2 32.77 6.45 25.40 28.80 29.60 30.30 30.43 30.90 Tester 3 31.00 -1.13 19.20 26.05 28.10 29.10 29.00 29.95 Tester 4 30.55 -7.60 21.17 24.90 28.30 28.05 28.85 29.33 Tester 5 32.15 -2.63 21.80 24.70 28.95 31.35 30.65 33.80

As a result, as shown in FIG. 2, the skin temperature dropped to almost 0 ° C or lower immediately after use, and was measured at an average temperature of 22 ° C after wiping after cleaning. When measured at intervals of 1 minute for 10 minutes, I could feel the coolness continuously for about 4 minutes.

[ Comparative Experimental Example . skin Cooling  effect]

The skin cooling effect was also tested for Comparative Examples 1 to 8 in the same manner as in the Experimental Example, and the results are shown in Table 4 below.
