Description

Specification

Stick cosmetic

Technical field

[0001] The present invention relates to a sticky cosmetic, and in particular, the lipstick cosmetic and the eye shadow cosmetic that have improved gloss when used, and that have good moldability and are not broken when used. It relates to cosmetics such as sticks.

Background art

[0002] Conventionally, sticky cosmetics, especially ordinary lipstick cosmetics, are composed of various oils, waxes, coloring materials, moisturizing agents, etc. As a characteristic, when applied to the lips, it is easy to apply by spreading smoothly, there is no stickiness when the upper and lower lips touch, there is some gloss on the lips, there is a moist feeling, the smell of the base The power that has been required to be low, etc.In particular, in recent years, the feeling of glossiness and moisture on the lips has been regarded as important, and the conventional technology has the disadvantage that the feeling of glossiness and moisture on the lips is not sufficient. It was. In order to eliminate this drawback and improve the gloss on the lips and moisturizing, various studies have been made in the past, but the level has still reached a sufficient level.

[0003] On the other hand, in sticky cosmetics, the moldability is good and the strength required to be unbreakable during use. To maintain these strengths, a relatively large amount of wax has been blended. . However, the addition of wax improves the moldability and folds during use, but has the disadvantage of poor gloss as described above, and the amount of wax is at least moldable and maintains a stick shape that does not fold during use. There has been a demand for cosmetics.

One way to improve moldability is to use a highly polar oil such as castor oil as the oil. In this case, it is known that moldability is maintained even if the amount of wax is reduced. It has been. However, in this case, the odor became odor over time, and the stability point was also desirable. Therefore, there has been a demand for a new polar oil component that has a high polarity and can reduce the amount of wax and has no drawbacks such as strength and odor.

[0004] Deeply related to the present application! For cosmetics containing pentaerythritol derivative oils, for example, cosmetics containing dipentaerythritol and esters of linear fatty acids (for example, Patent text 1), cosmetics containing esters obtained by reacting dipentaerythritol with straight chain fatty acids and dibasic acids (for example, Patent Document 2), tetra-2-ethylhexanoic acid pentaerythritol ester Contains cosmetics (for example, Patent Document 3), cosmetics formulated with an ester of pentaerythritol and a fatty acid and methoxy cinnamate (for example, Patent Document 4), and further contains a pentaerythritol derivative having a specific structure. Cosmetics (for example, Patent Document 5) are known.

BEST MODE FOR CARRYING OUT THE INVENTION

[0014] Hereinafter, the present invention will be described in detail.

The pentaerythritol full ester compounded in the sticky cosmetic composition of the present invention comprises pentaerythritol benzoate represented by the general formula (1), pentaerythritol 2-ethylhexanoic acid tetraester, It can also be a force.

Among these, as the ester of pentaerythritol and benzoic acid represented by the general formula (1), R ¹ is a 2-ethyl hexanoic acid residue having 8 carbon atoms, and R ² is an ester having a benzoic acid residue. Those represented by the following formula (2) are preferred. R ¹ is a 2-ethylhexanoic acid residue having 8 carbon atoms, and R ² is a linear or branched fatty acid residue having 1 to 24 carbon atoms, particularly an ester of a behenic acid residue. Those are also preferable, but are not necessarily limited thereto.

[0015] [Chemical 2]

[0016] The ester of this benzoic acid residue is obtained by reacting 1 mol of pentaerythritol with 3 mol of benzoic acid and 1 mol of 2-ethylhexanoic acid, followed by removal of unreacted substances, decolorization treatment, It can be obtained by deodorizing treatment.

[0017] In the present invention, the pentaerythritol benzoate ester represented by the general formula (1) and the pentaerythritol 2-ethylhexanoate tetraester are used in combination. The acid ester is all pentaerythritol During glycol ester, a 20 to 72 weight ^_0/0, is preferably 30 to 60 weight ^_0/0. If the ratio of the benzoate ester of pentaerythritol is too small, it will break easily, and if it is too much, the usability will be impaired.

[0018] The amount of pentaerythritol full ester, more preferably preferably fixture 10 to 80 weight ^_0/0 30 to 60% by weight relative to the cosmetic. If the blending amount is less than 10% by mass, the characteristics of high gloss are impaired. If the blending amount exceeds 80% by mass, the properties (color and moldability) of the lipstick are impaired.

[0019] In the present invention, the IOB as a whole of the oil containing the pentaerythritol full ester is 0.3 or more. When the amount of wax is in a very good range and the IOB is less than 0.3, the component composition of the present invention does not have hardness, and the moldability is deteriorated. Here, IOB (Inorganic Organic Balance) means the inorganic value / organic value, and is based on the organic conceptual diagram of Satoshi Fujita (Akira Fujita, Masami Akatsuka, Systematic Organic Qualitative Analysis (mixture)) 1974 , Published by Kyoritsu Publishing). It represents the polarity of the organic compound. The higher the value, the more polar the water becomes ∞.

[0020] In addition to the above, the oil used in the present invention includes hydrocarbon oils such as squalene, liquid paraffin, and cerine, myristic acid, palmitic acid, stearic acid, 12-hydroxystearic acid, and behenine. Higher fatty acids such as acids, higher alcohols such as cetyl alcohol, stearyl alcohol, oleyl alcohol, batyl alcohol, cetyl 2-ethyl hexanoate, 2-ethyl hexyl palmitate, 2-octyldodecyl myristate, neopentyl glycol 2-Ethylhexanoate, glyceryl trioctanoate, glyceryl triisostearate, glyceryl diisostearate, isopropyl myristate, myristyl myristate, glyceryl trioleate, olive oil, avocado oil, jojoba oil, castor oil Oil, safflower oil, coconut oil, macadamia nut oil, mink oil, lanolin, liquid lanolin, lanolin acetate, castor oil and other oils, dimethylpolysiloxane, methylphenol polysiloxane, highly polymerized gum dimethylpolysiloxane, polyether Examples thereof include silicone oils such as modified silicone and amino modified silicone, fluorine oils such as fluorine-modified dimethylpolysiloxane, fluorine-modified methylphenol polysiloxane, perfluoropolyether, and perfluorocarbon. In the present invention, it is preferable that the oil component does not contain castor oil or contains 5% by mass or less. Odor can be suppressed by using castor oil in a non-mixed amount or a small amount.

[0022] The amount of the oil containing pentaerythritol full ester is preferably in the range of 10 to 80% by mass.

In the present invention, 5 to 13% by mass, preferably 5 to: L 1% by mass of wax is blended. If it is less than 5% by mass, the moldability will be poor, and if it exceeds 13% by mass, the gloss will be poor.

[0024] Examples of the wax used in the present invention include carnapa wax, candelilla wax, beeswax, mole, ceresin wax, microcrystalline wax, and solid paraffin wax. Among these, it is preferable to include one or more selected from polyethylene wax, paraffin wax and candelilla wax. This is because, when these waxes are blended together with polyethylene wax, the filling temperature can be kept lower than that of polyethylene wax alone, so that production efficiency can be increased. On the other hand, from the viewpoint of moldability, it is also preferable to use polyethylene wax alone.

[0025] In addition to the above essential components, the stick-like cosmetic of the present invention is used in the usual cosmetics and pharmaceutical fields within the qualitative and quantitative ranges that do not impair the effects of the present invention, if necessary. Other components can be blended, and examples of the humectant include polyhydric alcohol humectants such as glycerin, propylene glycol, and 1,3 butylene glycol.

[0026] In addition, various emulsifiers, surfactants, thickeners, gelling agents, metal sarcophagus, water-soluble polymers, oil-soluble polymers, drugs, antioxidants, pigments, dyes, pearl agents, lame agents, Organic, inorganic powders, fragrances, etc. can be blended.

[0027] The stick-shaped cosmetic of the present invention is produced by heating and stirring and mixing the above-mentioned blending components including the essential components, followed by deaeration, filling into a container, and cooling. The dosage form of the cosmetic of the present invention is arbitrary, and can be, for example, a stick, pencil, paste or liquid, and a wZo emulsification system containing water and a humectant is also possible.

[0028] The sticky cosmetic of the present invention can be applied to general cosmetics such as lipstick cosmetics, eye shadow cosmetics, and hair cosmetics, and particularly sticks, pencils, etc. placed in a feeding container. Of cosmetics. Particularly preferred are lipstick cosmetics, in this case other than lipstick Also, it can be applied to lip daros, lip balm, etc. that do not contain coloring materials. Example

Next, examples of the present invention will be described.

The present invention is not limited to the following examples, and various modifications can be made without departing from the spirit of the present invention. In the following description, the unit of the blending amount is mass%.
