Cleaning Cosmetic Composition

Detailed description of the invention

The present invention relates to a cleaning (cleaning) cosmetic composition that cleans the skin soiled by makeup cosmetics and oily contaminants. More particularly, the present invention relates to a cleaning cosmetic composition characterized by having a very good cleaning power for makeup cosmetics containing a large amount of pigments surface-treated with silicone oil and the like, and improving water resistance, and having a fresh feeling in terms of feeling of use.

Recent makeup cosmetics use pigments that increase the adhesion to the skin and improve the feeling by treating the surface with various substrates such as silicone oil, and these surface-treated pigments are much more than the original pigment itself. The lipophilic properties were greatly increased and the water resistance was greatly increased. However, this resulted in a problem of being difficult to remove completely with conventional cleaning cosmetics.

Conventionally, cleaning products using emulsions include cleansing creams and cleansing lotions. The technologies related to the cleaning cosmetics have been described in Korean Patent Publication Nos. 89-1880 and Korean Patent Publication Nos. 90-8315. -117598, British Patent No. 28903, and the like are known, but these are usually emulsified products made by adding some synthetic or natural ester oils using a main oil component as a liquid paraffin, and use a large amount of raw materials surface-treated with recent silicones. It has been pointed out that not only has difficulty in removing makeup cosmetics such as two-way cakes, but also gives a feeling of oil in terms of feeling of use and gives unpleasant feelings after use.

In addition, as a conventional gel-type cleaning product, Japanese Patent Application Laid-Open No. 52-8905 and Japanese Patent Application Laid-open No. 60-115509 are known, and these are mainly in the form of a microemulsion and there is a risk of skin irritation using anionic surfactants. Or, there is a disadvantage in that the cleaning power is poor for makeup cosmetics containing a large amount of the pigment surface-treated with silicone.

Accordingly, the present inventors have intensively researched to solve the above disadvantages. As a result, the liquid paraffin, which has been mainly used in conventional cleaning cosmetics, has a weak affinity with the surface-treated silicone on the pigment, and thus the cleaning effect is reduced, and the skin after cleaning Remains in the form of a closed film to give a lot of oil was found to cause discomfort. Cyclomethicone, on the other hand, has excellent affinity with the surface-treated silicone on the pigments to provide excellent cleaning effect for makeup cosmetics using these pigments, and to remain on the skin after cleansing action due to its unique light and fresh feeling. It has a refreshing feeling almost without any problem. Polypropylene glycol alkyl ether is excellent in solvent power and removes various oily and aqueous contaminants deep in the skin. .

Accordingly, the present inventors use cyclomethicone and polypropylene glycol alkyl ether in combination to make a stable emulsion, and not only to remove makeup cosmetics containing a large amount of pigments surface-treated with silicone, but also to feel light and fresh. A cleaning cosmetic was prepared to complete the present invention.

Therefore, an object of the present invention is to provide a cleansing cosmetic composition which helps to remove makeup cosmetics of various kinds and makes the feeling more refreshing during or after use of the cleaning cosmetics.

The present invention is described in detail as follows.

The cleaning cosmetic composition of the present invention is an emulsified cleaning cosmetic containing 5.0-50.0 wt% of cyclomethicone and 5.0-35.0 wt% of polypropylene glycol alkyl ether, and a large amount of pigments surface-treated with silicone by using them in combination It is also an excellent cleaning cosmetic composition that provides excellent cleaning effect on the makeup cosmetics contained, and gives a light and refreshing feeling during use or after use.

In the present invention, when the content of cyclomethicone and polypropylene glycol alkyl ether is 5.0 wt% or less, the cleaning effect is insignificant, and when the cyclomethicone is 50.0 wt% or more and polypropylene glycol alkyl ether 35.0 wt% or more, It is not desirable because it is in poor condition and degrades the value of the product.

The polypropylene glycol alkyl ether used in the present invention means that the number of moles of polypropylene glycol is 5 to 30, which means that the cleaning effect is insignificant when the number of moles of polypropylene glycol is 5 or less and the state of the emulsion is more than 30. This is because it is difficult to use.

In the present invention, the use of cyclomethicone and polypropylene glycol alkyl ether alone does not have the effect, but when used in combination together, even if a smaller amount is used, a better effect can be obtained than when used alone. .

Looking at the preparation method of the cosmetic composition according to the present invention, first, cyclomethicone, polypropylene glycol alkyl ether, cetostearyl alcohol, beeswax, purified stearic acid, synthetic ester oil, microcrystalline lead, bio-surfactant, etc. To 50.0 to 70.0% by weight, and as the aqueous phase, 2.0 to 10.0% by weight of polyhydric alcohols such as glycerin, a thickener, a flavoring agent, and a preservative are added, and the remaining amount is purified water, and the total amount is 100% by weight. These oil phase components and water phase components were dissolved by heating at 75 to 80 ° C., respectively, and the oil phase components were gradually added to the aqueous phase components. The oil phase component was emulsified at 3000-4500 RPM using a homogenizer at 75 ° C. to 80 ° C., and then cooled to room temperature. Manufacture. The cleaning cosmetic composition of the present invention can be applied to both the creamy, latex and microemulsion cleaning cosmetics.

Hereinafter, the present invention will be described in more detail based on Examples and Comparative Examples.

Example 1-2 and Comparative Example 1-5
