Description

Makeup Cleansing Cosmetic product {Cosmetic product for cleansing makeup}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleansing cosmetic product such as a make-up product, and more particularly to a cleansing cosmetic product effective for removing make-up with high water-repellent and oil-repellent functions.

Water-proof function that can maintain its efficacy even in the presence of moisture such as sweat and tears, and at the same time, the use of makeup products having excellent persistence is increasing. Especially, as the formulations of point make-up for diverse productions have become diverse, the market demand for products with excellent cleansing effect is increasing. In addition, if the makeup can not be properly removed, the skin can not be kept clean and can cause skin diseases. Therefore, it has become important to develop a product that does not irritate the skin even though it has excellent cleansing power.

Products for make-up cleansing can be classified as a two-layer type of water-phase such as a mascara exclusive eye remover, an oil-based type such as a cleansing cream or a cleansing oil, a cleansing water or a water-based type of a cleansing gel containing a large amount of a surfactant.

Especially, in the case of the exclusive remover having strong washing power against the point make-up, silicone oil such as cyclopentasiloxane or cyclohexasiloxane is mainly composed. Silicone oils are known to have good spreadability in the skin and have low molecular weight but low penetration into the skin due to the formation of a ring structure and also blocking the pores. When silicone oil is used in remover products, it is effective for removing a silicone-derived polymer compound or a resin such as resin. However, since the silicon-based encapsulant has a weak oil-repellent function, it has recently been insufficient to clean the point-makeup product, which has a stronger water-repellent / oil-repellent function, by using the encapsulant having a mixture of hydrophobic property and hydrophilic property.

In addition, the silicone oils mainly used are limited to use in wash-off formulations because they form an oil film and cause water pollution. In addition, there is a growing negative perception of consumer awareness about the use of silicone oils that can block pores and cause problems.

Korean Registered Patent No. 10-0891155 (Published on April 6, 2009)

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an effective makeup cleansing cosmetic composition, in particular, a cleansing cosmetic composition effective for erasing recent makeups having high water repellency and oil repellency.

Another problem to be solved by the present invention is to provide a cosmetic material which is highly resistant to make-up and has no irritation to the skin, and which can remove the skin wastes cleanly.

(A) an alkoxy group of esters having a carbon number of 12-24, and (b) an alkoxy group of an ester group. The present invention relates to a water- And acyl groups each having a branched structure other than isopropyl, and (b) at least one selected from the group consisting of isododecane, isohexadecane, hydrogencarbonate The present invention provides a cosmetic product for cleansing, which comprises at least one hydrocarbon compound selected from the group consisting of polyisobutene, polyisobutene, and hydrogenated polydecene.

Preferably, in the cosmetic composition of the present invention, the carbon number is 12-24, the terminal of each of the alkoxy group and the acyl group of the esters is branched from the isopropyl group, The linear ester oil not containing the structure is hexyl laurate, isononyl isononanoate, or a mixture thereof.

In the case of other ester oils other than the particular ester oils (e.g., glyceryl, trioctanoate) wetting is less desirable to eliminate recent makeup.

In the cosmetic of the present invention, the content of such an ester oil is preferably from 10 to 20% by weight based on the total weight of the oil phase portion and the water phase portion, for the purpose of the present invention. If it is contained in an amount of less than 10% by weight, it is not easy to expect satisfactory cleansing-enhancing effect because it is poor in compatibility with makeup or skin wastes and wettability. If it is 20% by weight or more, the ester oil has a weakly surfactant action, resulting in poor usability of the composition.

Preferably, the oily portion of the cosmetic composition of the present invention is isododecane, isohexadecane, hydrogenated polyisobutene (preferably number average molecular weight 180 to 400), and hydrogenated polydecene (preferably number average molecular weight 260 To 820). For the purpose of the present invention, the hydrocarbon compound is at least one of isododecane and isohexadecane, and at least one of hydrogenated polyisobutene and hydrogenated polydecene Or a mixture thereof.

In the present invention, the content of the hydrocarbon compound is preferably 25 to 45% by weight based on the total weight of the oil phase portion and the water phase portion. When it is contained in an amount of less than 25% by weight, it is less preferable that a large amount of air bubbles remain on the wall surface during the layer separation in the two-layer type formulation, Also, when it is constituted up to 45% by weight, it is less preferable because there is a possibility that the stability of the inside of the formulation may be deteriorated due to an increase in oil residual feeling after cleansing.

Preferably, the cosmetic product of the present invention comprises 25 to 45% by weight of a specific hydrocarbon compound, based on the total weight of the oil phase and the water phase; 10 to 20% by weight of a particular ester oil; 0.01 to 3% by weight of a surfactant; And residual water.

In the cosmetic composition of the present invention, the water phase part contains a surfactant for imparting washing power through the phase transfer and self-emulsification in the washing process. In particular, for the purpose of the present invention, a nonionic surfactant, an anionic surfactant and an amphoteric surfactant In view of the emulsifying effect of the hydrocarbon compound and the ester oil.
