Description

[0001] BASIC COSMETIC COMPOSITION CONTAINING POLYETHOXYLATED URETHANE DERIVATIVES [0002] The present invention relates to a cosmetic composition containing a polyethoxylated urethane derivative,

More specifically, the present invention relates to a cosmetic composition for basic cosmetics, which comprises a polyethoxylated urethane derivative and can remove color cosmetics with lukewarm water without a separate cleansing product, The present invention relates to a cosmetic composition for basic cosmetics which exhibits an excellent ultraviolet ray blocking effect.

In case of making a hue, generally after completing the basic make-up stage, the sunscreen is applied and then the hue is cremated. At this time, the color cosmetics to be applied to the skin are usually not cleansed with water, so cleansing products for erasing the color cosmetics are separately used.

However, cleansing products contain surfactants and oils. There is a problem such as physical stimulation to the skin by using the tissue off method in order to eliminate the skin irritation caused by the use of the surfactant, the residual feeling of the used oil, and the residual feeling of the oil. As a solution to this problem, there is a method of removing color makeup using only lukewarm water without using a cleansing product. However, there is a lack of research on the method of not using the cleansing product, and it is required to develop a product which can remove the makeup with lukewarm water without a separate cleansing product. In this case, when the color makeup is erased in the water at room temperature instead of the lukewarm water, there may be a problem that the color makeup is erased by the gargle, the rain, or the secretion such as sweat or tears.

Particularly, it is important to develop a separate product for removing color cosmetics with lukewarm water. However, in such a case, it may be cumbersome and economical to apply a separate product to the skin before makeup. Therefore, it is generally required to develop a technique that can be included in an ultraviolet (UV) blocking cosmetic composition to be used before making a hue, and that can eliminate the inconvenience and inconvenience of cleaning.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The foundation cosmetic composition according to the embodiment of the present invention may include a polyethoxylated urethane derivative.

At this time, the polyethoxylated urethane derivative serves as a temperature-sensitive polymer. When the foundation cosmetic composition is applied to the skin, the polyethoxylated urethane derivative contained in the cosmetic composition for foundation cosmetic can form a molecular arrangement, wherein the molecular arrangement is such that the hydrophilic group is arranged in the skin direction , And the lipophilic group may be arranged in the outward direction of the skin. In addition, because of the nitrogen that can bind hydrogen and water in the molecule, it is dissolved in water and hydrogen bond at low temperature. However, when temperature rises, the hydrogen bond weakens and gelling phenomenon appears. Therefore, when it is applied to the skin, it can exist in a state of being combined with water at a low temperature, that is, in a dissolved state, so that a foreign body feeling is not felt unlike a general film forming agent. In the lukewarm water, the hydrogen bonding with water is weakened due to the rise in temperature, so that the lipophilic parts are bundled together to minimize the part in contact with water, and the polyethoxylated urethane derivative is easily removed by this gelling phenomenon. The color makeup formed thereon can be easily removed together. The cosmetic composition for basic cosmetics containing the composition is excellent in feeling and skin stability and can be easily washed with lukewarm water.

In the present invention, polyethoxylated urethane derivatives are formed by the reaction of an ethoxylated fatty alcohol and an aliphatic diisocyanate.

At this time, the aliphatic diisocyanate is one of hexamethylene diisocyanate, trimethylhexamethylene diisocyanate, methylene dicyclohexyl diisocyanate, and isophorone diisocyanate . Are the compounds represented by the following formulas (1) to (4), respectively.

Hexamethylene diisocyanate

Trimethyl hexamethylene diisocyanate

Methylenedicyclohexyl diisocyanate

Isophorone diisocyanate

And the ethoxylated fatty alcohol is a compound represented by the following formula (5).

Ethoxylated fatty alcohol

The polyethoxylated urethane derivative represented by the following general formula (6) can be derived.

In the general formula (6), m and n are integers, each independently an integer of 50 to 200. When m and n are 49 or less, there is a problem that they are not dissolved well in water. When m and n are more than 201, there is a problem that the makeup is not removed well when washing with lukewarm water.

And R1 may be an aliphatic hydrocarbon or a cycloaliphatic hydrocarbon. More specifically, it may be hexamethane, trimethylhexamethane, methylenedicyclohexane, or isophorone as shown in the above-described formulas (1) to (4).

R2 and R3 are collectively referred to as an alkyl group. When the number of carbon atoms in the alkyl group is less than 7, there is a problem that the makeup is not easily removed when washing with warm water. When the number of carbon atoms in the alkyl group is more than 31, there is a problem that it is not dissolved well in water. Therefore, R2 and R3 each independently can be an alkyl group having 8 to 30 carbon atoms.

< Experimental Example  9: UV protection evaluation (suppression of erythema response)>

in - vivo  SPF measurement

Twenty women aged 20 to 40 years were subjected to the same procedures as in Example 7 to 12 and Comparative Example 2 except that the foundation cosmetic composition having an ultraviolet shielding function was applied to an area of 24 cm ² for the coating in an amount of ² mg / cm 2 and allowed to stabilize for 20 minutes. An Oriel solar UV simulator (Oriel Instrument, USA) equipped with a 1000 W xenon arc lamp (ozonless) as a light source for UV-B was installed through a light guide with a diameter of 8 x 8 inch, fixed with 2 × 10 ³ light intensity in μW / cm ^2, and the time and amount of light (model: smartmeter GRP-1, Oriel, USA), by measuring the ultraviolet ray quantity and the time that the first erythema occurred in tuned - vivo SPF , And the results are shown in Table 11.

Example 7 Example 8 Example 9 Example 10 Example 11 Example 12 Comparative Example 2 in - vivo SPF 18 ± 0.01 20 ± 0.01 29 ± 0.01 37 ± 0.01 35 ± 0.01 30 ± 0.01 16 ± 0.01

The in - vivo SPF is derived from the sun protection factor (MED for sun protection products / MED for sun protection products). Where MED is the minimum amount of ultraviolet radiation (or time) that causes erythema. That is, the higher the number of in - vivo SPF, the stronger the blocking function. For example, when the UV dose is 1, applying an SPF15 blocker reduces the amount of ultraviolet light reaching the skin to one-fifteenth of that.

As can be seen from the above Table 11, Examples 7 to 12 including the polyethoxylated urethane derivative showed an increase in ultraviolet blocking effect as compared with Comparative Example 2 which did not include the polyethoxylated urethane derivative And in particular, Examples 9 to 12 confirmed that the ultraviolet blocking effect was remarkably increased.
