Description

Oily type solid make-up cosmetic composition

The present invention relates to a solid make-up cosmetic composition of the oily type with improved skin shine phenomenon.

In general, when the makeup cosmetics are applied to the skin, they are attached for about 8 to 12 hours, and the makeup membrane is changed by skin secretions such as sweat or sebum secreted from the skin while being attached. When the cosmetic film changes, the cosmetics appear in various physical forms, such as lifting, agglomeration, dull color, or bleeding. Especially, in the case of base makeup products, bleeding phenomenon caused by sebum or sweat secreted after makeup Since the makeup effect is most degraded, such as making the makeup unnatural, women using makeup cosmetics are most dissatisfied.

Skin shine is a phenomenon that appears when the specular reflectance to light is high, and it occurs when the skin surface is wet or cosmetics are wetted by sebum generated on the skin surface over time after makeup. Such methods for reducing specular reflectance include artificially using a film forming agent capable of forming a strong film on the surface of the skin, a method of reducing sebum generation of the skin itself, a method of using powders that are not easily wetted with sebum, and a film forming agent capable of forming a strong film on the surface of the skin. And a method of continuously absorbing sebum generated using powder having a high oil absorption ability. In general, Korean Patent Laid-Open Publication Nos. 2005-0071275 and 2003-0015586 disclose compositions that reduce sebum generation amount of skin itself using natural ingredients, which is suitable for emulsifying cosmetics containing an aqueous phase. It is very difficult to apply to the type of cosmetics and has the disadvantage that it takes a lot of time to actually feel the effect.

In addition, Korean Patent Laid-Open Publication No. 2005-0058550 and 2003-0043114 disclose a composition which minimizes the wetting by sebum by applying a single or double coating on the surface of the powder, the composition as described above in most makeup cosmetics This is generally used, but there is a limit to minimizing sebum wet after a certain time.

In addition, Korean Laid-Open Patent Publication No. 2005-0027436 discloses a composition containing a film-forming agent for forming a film on the skin surface. When the composition is used in a small amount, the film-forming ability decreases and the feeling of use of the cosmetic product is used when used in a large amount. There is a disadvantage in that it is difficult to control the actual content of the greatly dropped.

In addition, Korean Patent Laid-Open Publication No. 2004-0096108 discloses a cosmetic composition containing hydrophobic silica to suppress sebum by sebum, which is used as a cosmetic that does not grease and become dull by absorbing sebum generated from the skin. However, it is mainly used for the powder type foundation, not the oil type, and when used in the solid type oil type, such as this patent has a disadvantage of making the molding difficult to drop the fluidity.

Therefore, the technical problem to be achieved by the present invention is that the fluidity is good and the molding is easy and the oil absorption ability for sebum is excellent, the skin bleeding does not occur even after a long period of time to maintain a low reflectivity as well as sweating phenomenon caused by external temperature change The present invention provides a solid makeup cosmetic composition of an oil-based type having excellent long-term stability and excellent usability such as application property, adhesion, application uniformity and makeup persistence.

In order to achieve the above technical problem, the oil-based solid makeup cosmetic composition containing the wax, oil and pigment of the present invention is 3 to 15% by weight of wax, 20 to 60% by weight of oil and 10 to 50% by weight of pigment Wherein the pigment is any one selected from the group consisting of vinyl dimethicone / methicone silsesquioxane crosspolymer powder, silica powder and mixtures thereof based on the total weight of the composition and polymethylmethacrylate powder 1 20 wt%.

In the oil-based solid makeup cosmetic composition according to the present invention, the wax includes candelailla wax, carnauba wax, rice wax, beeswax, lanolin, ozokerite, ceresin wax, paraffin wax, microcrystalline wax, polyethylene Wax etc. can be mentioned, These waxes can be used individually or in mixture of 1 or more types. Especially preferred are ceresin wax, carnauba wax or mixtures thereof.

In the oil-based solid makeup cosmetic composition according to the present invention, the oil is cetylethylhexanoate, neopentylglycol dicaprate, isocetylethylhexanoate, distearylmaleate, triethylhexanoin, squalane, capryl Rick Capric triglyceride, pentaerythritol tetraethylhexanoate, butylene glycol dicaprylate caprate, hexyllaurate, dimethylpolysiloxane, methylphenylpolysiloxane, decamethylcyclopentasiloxane, methyltrimethicone, phenyltrimethicone, methicone Chicon, dimethicone, cyclomethicone, liquid lanolin, olive oil, avocado oil, jojoba oil, macadamia oil, and the like, these oils may be used alone or in combination of one or more thereof. Particular preference is given to butylene glycol dicaprylate caprate, dimethicone or mixtures thereof.

In the oil-based solid makeup cosmetic composition according to the present invention, the pigments include titanium dioxide, particulate titanium dioxide, zinc oxide, iron oxide, titanium dioxide oxide composite, alumina, talc, mica, kaolin, barium silicate, zeolite, dolomite, Synthetic mica, magnesium carbonate, barium sulfate, iron titanate, titanium oxide coated mica, polystyrene powder, polymethyl methacrylate powder, polyethylene powder, nylon powder, silicone powder, and the like. It can mix and use the above.

Hereinafter, the present invention will be described in detail.

The present invention is an oil-based solid makeup cosmetic composition containing a wax, oil and pigment, comprising 3 to 15% by weight wax, 20 to 60% by weight oil and 10 to 50% by weight pigment, wherein the pigment is the total weight of the composition 1-20 wt% of any one selected from the group consisting of vinyl dimethicone / methicone silsesquioxane crosspolymer powder, silica powder, and mixtures thereof and 1-20 wt% of polymethylmethacrylate powder It provides a solid makeup cosmetic composition of the oil-type, characterized in that it comprises.

The wax contained in the oil-based solid makeup cosmetic composition according to the present invention is used to solidify or impart a gloss of cosmetics, and suitable waxes include plant-based systems such as candelailla wax, renauba wax and rice wax. Animal waxes such as waxes, beeswax, lanolin, mineral waxes such as ozokerite, ceresin wax, paraffin wax, microcrystalline wax, petroleum wax such as polyethylene wax, and ester waxes which are solid at 25 ° C. Ceresin wax, carnauba wax or mixtures thereof are preferred. If the content of wax is 3.0 wt% or less, there is a disadvantage in that stick breakage occurs on the stick, and when it is 15.0 wt% or more, it is advantageous to form the stick, but the wearability is not smooth and stiff. Content control is important.

The oil which may be contained in the oil-based solid makeup cosmetic composition according to the present invention is cetylethylhexanoate, neopentylglycol dicaprate, isocetylethylhexanoate, distearylmaleate, triethylhexanoin, squalane, carca Pryric capric triglyceride, pentaerythritol tetraethylhexanoate, butylene glycol dicaprylate caprate, hexyllaurate, dimethylpolysiloxane, methylphenylpolysiloxane, decamethylcyclopentasiloxane, methyltrimethicone, phenyltrimethicone, Methicone, dimethicone, micromethicone, liquid lanolin, olive oil, avocado oil, jojoba oil, macadamia oil, silicone oil and ester oil, and the like, butylene glycol dicaprylate caprate, dimethicone or Mixtures of these are preferred. If the oil content is less than 20% by weight, the fluidity is poor, the moldability is poor, and if the content is more than 60% by weight, the moldability is improved, but the solidity ability is poor and the oily feeling is increased due to the oily feeling.

Pigments which may be contained in the oil-based solid makeup cosmetic composition according to the present invention include titanium dioxide, particulate titanium dioxide, zinc oxide, iron oxide, titanium dioxide oxide complex, alumina, talc, mica, kaolin, barium silicate, zeolite, and mica.

If the content of the pigment is less than 10% by weight, there is a lot of oil, so the usability is reduced and the oil-absorbing ability of the sebum is reduced, but if the content is more than 50% by weight, the moldability is poor and the applicability is deteriorated.

Since the vinyl dimethicone / methicone silsesquioxane crosspolymer powder and silica powder contained in the oil-based solid makeup cosmetic composition according to the present invention have a large specific surface area, they have excellent oil absorption ability against oil and sebum, so that the sebum after makeup Continuously absorb the oil to prevent skin shine. In addition, it suppresses sweating caused by external temperature change, which is the biggest problem in solid cosmetics, thereby increasing the stability of the cosmetics. However, if a large amount is used, a problem of deterioration in moldability due to a large drop in fluidity after manufacture, and the use of a small amount may not prevent skin bleeding, and thus content control is important.
