Description

Solid foundation cosmetic compositions having various three-dimensional shapes

The present invention relates to a solid foundation cosmetic composition for molding.

Foundation is a cosmetic that is applied to the face and neck to even out skin tone and smooth skin texture. The foundation is a variety of colors to choose a product that matches your skin color to keep the face bright. Spreading thinly and evenly can shine your skin and make your skin look good. Foundations include liquid foundations, powder foundations, and solid foundations called skin covers.

In general, a solid type foundation includes a water-in-oil or oil-in-water solid foundation emulsified by dispersing the powder in the oil phase or water phase component and a dispersed solid foundation in which the powder is dispersed in the oil phase. Disperse solid foundation has the advantage of providing high covering power and make-up durability, while the powder content is high, so it feels dry on the skin after applying the cosmetics, or because of the thick makeup film, it becomes unnatural makeup expression. have. In case of increasing the content of various kinds of powder in order to enhance the finish and make-up lasting in the dispersed solid foundation, the user can feel the dryness of the skin immediately after applying the product or the make-up film is excited by the dead skin of the skin surface. Becomes difficult. In addition, there is a drawback that the makeup is often unnaturally expressed by a thick makeup film. When the powder content is reduced in the dispersed solid foundation, it is difficult to secure stability such as oil separation in the solid foundation, and there is a limitation in implementing a smooth finish and lasting makeup.

Therefore, there is a need for a makeup cosmetic composition to be developed to include excellent powder or excellent while excellent feeling and coverage.

One aspect is dextrin palmitate, polyamide-8, polyamide-3, ethylene diamine / hydrogenated dimer dilinoleate copolymer bis-D-C14- 18 alkyl amides (Ethylene diamine / Hydrogenated Dimer Dilinoleate Copolymer Bis-Di-C14-18 Alkyl Amide), Quaternium-18 Hectorite, Stearalkonium Hectorite, Disteardi At least one thickener selected from the group consisting of Disteardimonium Hectorite, Dibutyl ethylhexanoyl glutamide, and Dibutyl lauroyl glutamide It is to provide a dispersible solid foundation cosmetic composition.

One aspect is dextrin palmitate, polyamide-8, polyamide-3, ethylene diamine / hydrogenated dimer dilinoleate copolymer bis-D-C14- 18 alkyl amides (ethylene diamine / Hydrogenated Dimer Dilinoleate Copolymer Bis-Di-C14-18 Alkyl Amide), Quaternium-18 Hectorite, Stearalkonium Hectorite, Disteardi At least one thickener selected from the group consisting of Disteardimonium Hectorite, Dibutyl ethylhexanoyl glutamide, and Dibutyl lauroyl glutamide It provides a dispersed solid foundation cosmetic composition. The composition has an effect of being in close contact with the skin with a smooth feeling and stability by including an oil thickener without using a wax.

The thickener may be included in 0.1 to 10% by weight of the total composition. For example, 0.1 to 10% by weight, 0.1 to 8% by weight, 0.1 to 6% by weight, 0.1 to 4% by weight, 1 to 8% by weight, 1 to 7% by weight, 1 to 5% by weight, 2 to 9% by weight %, 3 to 8% by weight, 4 to 7% by weight, or 5 to 6% by weight. At this time, when the content of the thickener is less than the above range, there is a problem that it is difficult to sufficiently exhibit the oil phase increase effect, and it is difficult to maintain a solid shape. There is a problem that the feeling of use of the cosmetic is lowered.

In one embodiment, the oil phase thickener may be dibutyl ethylhexanoyl glutamide and dibutyl lauroyl glutamide. The dibutyl ethylhexanoyl glutamide and dibutyl lauroyl glutamide may be mixed in a ratio of 1: 1 to 3: 2. For example, 1: 1 to 3: 2, 1: 1 to 1: 2, 1: 1 to 1: 3, 2: 1 to 3: 1, or 2: 3 to 3: 2. In this case, when the mixing ratio of dibutyl ethylhexanoyl glutamide and dibutyl lauroyl glutamide is less than the above range, there is a problem that the composition is cracked or broken despite having an appropriate hardness and exceeds the above range, The melting point of the composition is about 120 ℃ is very high, there is a problem that it is difficult to handle the formulation.

The composition may be one containing no silicone-based oil. The silicone oil may be, for example, dimethicone, phenylpropyldimethylsiloxysilicate, trimethyl pentaphenyl trisiloxane, diphenylsiloxy phenyltrimethicone, or the like. Since the composition does not include silicone-based oils, it is possible to minimize skin irritation and prevent skin troubles, so that the composition can be applied to sensitive skin. Can meet their needs

The composition may further comprise a powder pigment. The powder pigment is, for example, silica (silica), mica / dimethicone (mica / dimethicone), sericite / dimethicone (sericit / dimethicone), titanium dioxide, zinc oxide (Zincoxide), polymethylsil Sesquioxane (Polymethylsilsesquioxane), Polymethyl Methacrylate, Talc, Mica, Alumina, Barium Sulfate, Magnesium Myristate, Iron Oxide ( Iron oxide, nylon-12, HDI / trimethylol hexyllactone crosspolymer, methyl methacrylate crosspolymer, kaolin, and the like. . The powder pigment may be selected in consideration of ultraviolet ray blocking function, coverage, color and spreadability. In one embodiment, the powder pigment may be coated for dispersibility and persistence. In this case, the powder pigment is Methicon, Dimethicon, Triethoxycaprylylsilane, Isopropyl Titanium Triisostearate, Magnesium Stearate , Glyceryl Behenate, Aluminum Stearate, DEA-C8-18 Perfluoroalkylethyl Phosphate, or a mixture thereof. . In another embodiment, the powder pigment may be included in 5 to 60% by weight of the total composition. For example, 5 to 55%, 5 to 45%, 5 to 35%, 5 to 25%, 5 to 15%, 10 to 55%, or 15 to 45% by weight. . In this case, when the content of the powder pigment is less than the above range, there is a problem that the effect of the smooth finish and coverage can not be sufficiently exhibited. If the powder pigment exceeds the above range, the skin dryness is increased and smooth cosmetic expression is difficult, as well as formulation stability and usability. There is a problem that can fall.

 The composition may further comprise a humectant. The moisturizing agent may include, for example, a polyol selected from the group consisting of glycerin, butylene glycol, propylene glycol, dipropylene glycol, pentylene glycol, hexylene glycol, polyethylene glycol, sorbitol, or any combination thereof. Specifically, the polyol may be included in 0.1 to 5% by weight of the total composition of the composition. For example, it may be included in 0.1 to 5% by weight, 0.1 to 4% by weight, 0.1 to 2% by weight, 0.1 to 1.5% by weight or 0.1 to 1% by weight. At this time, when the content of the polyol is less than the above range, there is a problem that the moisturizing persistence is lowered, and when exceeding the above range, there is a problem that affects the formulation stability and the feeling of use decreases due to the increase in stickiness and dampness.

Compositions according to one embodiment may exhibit levels of hardness usable as solid cosmetics. For example, the hardness of 30 to 500N, 30 to 400N, 30 to 300N, 30 to 200N, 30 to 100N, 50 to 500N, 50 to 300N, 50 to 150N, or 100 to 200N. At this time, if the hardness of the composition is less than the above range there is a problem that the formulation stability and usability may fall, and if it exceeds the above range there is a problem that the composition is not taken to the puff as well as difficult to manufacture.
