Description

Lip makeup composition

The present invention relates to a lip makeup composition, and more particularly, it is applied to the lip interface to prevent color bleeding and oil bleeding of lip cosmetics, especially liquid lip cosmetics, such as lip gloss, to keep the lip makeup neat even after elapse of time. Since the color is transparent, it does not affect the color of other lip cosmetics that imparts color to the lips, and has a high temperature stability and long-term stability such as sweating and blooming, etc. will be.

The lip liner of the conventional stick formulation contains a large amount of inorganic pigments and organic pigments for the lipstick to sharpen the lip interface, and also has a slight color bleeding prevention effect. However, it was not enough to prevent the spread of lip gloss, which is much more smeared than lipstick, as the current makeup behavior has shifted from using lipstick to lip gloss. In addition, the existing lip liner has the same dark color as lipstick, so when applying lip cosmetics such as lipstick of different colors or lip gloss of transparent color to the lips, a border due to the color difference is created. It has troublesome disadvantages in makeup such as not being noticeable.

In addition, Korean Patent Publication No. 1998-053648 uses a swelling polymer material with volatile silicone oil for a lip liner that is hard to get off and is not easily erased. When used, the core may break or lose shape, and the use thereof is also a color lasting lip liner, which is different from the color bleeding prevention and colorless liner of the present invention.

Therefore, the technical problem to be achieved by the present invention is to prevent the color bleeding and oil bleeding of the lip cosmetics, especially liquid lip cosmetics, such as lip gloss by applying to the lip interface to maintain the lip makeup neat after time, the application color is transparent It is an object of the present invention to provide a lip liner makeup composition of a stick formulation having excellent color stability and high long-term stability and spreadability such as high temperature stability, sweating and blooming, even when applying a lip cosmetic of another color.

In order to achieve the above technical problem, the present invention is based on the total weight of the composition 5 to 30% by weight wax, 10 to 70% by weight ester oil, 1 to 20% by weight siloxane oil and 10 to 60% by weight siloxane polymer It provides a lip makeup composition comprising a.

Hereinafter, the lip liner composition according to the present invention will be described in more detail.

The wax included in the lip makeup composition of the present invention may be any of plant waxes, animal waxes, mineral waxes, and synthetic waxes, but may be used to prevent phenomena such as sweating and blooming and to ensure high stick stability at high temperatures. It is preferable to use a melting point synthetic wax, wherein high melting point means that the minimum melting point is more than 80 ℃.

Specific examples include ethylene / propylene copolymers, synthetic waxes, and polyesters. In addition, plant waxes, animal waxes, and mineral waxes may be used in combination for use and other reasons. Such parallel use waxes include carnauba wax, candelilla wax, microcrystalline wax, ceresin, and the like.

The content of the wax is preferably used in 5 to 30% by weight based on the total weight of the composition. If the content of the wax is less than 5% by weight, the stick formation is incomplete, and the high temperature stability such as breaking or bending at high temperature is not sufficient. If the content of the wax is more than 30% by weight, the hardness rises excessively and the feeling of use decreases.

In addition, the lip makeup composition of the present invention preferably contains an ester-based oil having excellent compatibility with wax in order to impart a softening effect and flowability at high temperature filling. As the ester oil, it is preferable to use an ester oil having 17 to 38 carbon atoms. Preferred examples include diisostearyl maleate, trioctanoin, neopentyl glycol dicaprylate, polyglyceryl-2triisostearate, and the like, which can be used alone or in combination of one or more thereof.

The amount of the ester oil is preferably 10 to 70% by weight based on the total weight of the composition. If the content of the ester-based liquid oil is less than 10% by weight not only does not provide sufficient flexibility, it is not easy to manufacture, if it exceeds 70% by weight it is difficult to give sufficient hardness to the product.

The siloxane oil included in the lip makeup composition of the present invention may be used to facilitate dispersibility of the siloxane polymer, and specific examples thereof include phenyltrimethicone, caprylyl trimethicone, and trimethyl pentaphenyl trisiloxane.

The content of such siloxane-based oil is preferably used 1 to 20% by weight based on the total weight of the composition. If the content of the siloxane-based oil is less than 1% by weight, the dispersion of the siloxane-based polymer is not sufficient, and if it exceeds 20% by weight, it is difficult to give sufficient hardness to the product.

In addition, the siloxane-based polymer acts as a protective film to block the flow of oil components together with the wax to prevent color bleeding by inhibiting the flow of oil components of liquid lip cosmetics, such as lip cosmetics, particularly lip gloss, and pigment components dispersed therein. Give lip makeup even after time passes.

In addition, most of the powder part of the existing lip liner is an inorganic pigment or an organic pigment that gives a color, and therefore has a dark color such as lipstick, so that the color difference when applying lip cosmetics such as lipstick of different colors or lip gloss of transparent color to the lips Although a border line is formed, since the siloxane polymer is used as the powder part of the present invention, color does not appear, and color border lines do not occur even when a lip cosmetic of different colors is applied. In addition, colorless mica or talc may be used, but siloxane-based polymers are preferable because there is a risk of deterioration in transparency and a lack of softness and a limit of the maximum content that can be contained.

The content of the siloxane-based polymer is 10 to 60% by weight based on the total weight of the composition, and when the content is less than 10% by weight, the effect of preventing color bleeding and oil bleeding of the lip cosmetics cannot be expected, and exceeds 60% by weight. If you do, there is a problem that the stick is easy to break the feel is not soft.

As such a siloxane polymer, a simple siloxane polymer, a siloxane cross polymer, or the like may be used, and a siloxane cross polymer is more preferable. More specifically, there are dimethicone crosspolymers, dimethicone / vinyl dimethicone crosspolymers, dimethicone polyethylene glycol (PEG) 10/15 crosspolymers, vinyl dimethicone / methicone silsesquioxane crawl polymers, silica, and the like. Or mixed.

In addition, the lip makeup composition of the present invention may further include additives such as preservatives, humectants, preservatives, UV absorbers, fragrances that can be used in the art, if necessary.

The preparation method of the lip makeup composition of the present invention is not particularly limited, and for example, the components may be uniformly dispersed while heating to a temperature of 85 to 90 ° C. after mixing, degassing and cooling at room temperature.

As described above, the lip makeup composition of the present invention is applied to the lip interface to prevent color bleeding and oil bleeding of the liquid lip cosmetics, such as lip cosmetics, particularly lip gloss, bleeding, the application color is transparent, high temperature stability and sweating and Long-term stability, such as blooming, is also improved.

Hereinafter, examples and the like will be described in detail to help understand the present invention. However, embodiments according to the present invention can be modified in many different forms, the scope of the invention should not be construed as limited to the following examples. Embodiments of the present invention are provided to more fully describe the present invention to those skilled in the art.
