 Stick cosmetic

 Technical field

 [0001] The present invention relates to a stick cosmetic. In more detail, shape retention, usability

 It relates to sticky cosmetics that are extremely excellent (especially at the time of application and gloss). Background art

 [0002] Stick-shaped cosmetics are important as cosmetics for lips such as lipsticks, lip creams, lip lips, lip pencils, and the like.

[0003] Of these, oil-type lip cosmetics include liquid oils (for example, castor oil, jojoba oil, squalene, lanolin, various synthetic ester oils, liquid paraffin), and wax (solid agent: for example, carnaparou. The powder is dispersed in a mixture with Candelillaro, Celesin, Microcrystalline Wax, Hardened Animal Oil, Hardened Vegetable Oil, Millow).

[0004] The above-mentioned oily-type cosmetics for lips must satisfy the required shape-retaining properties and feeling of use (especially the spread and gloss when applied) by adjusting the mixing ratio of wax and liquid oil. I must.

 However, it is very difficult to satisfy sufficient shape retention and usability at the same time.

 [0005] Because wax is an essential component for solidifying liquid oil, a sufficient amount must be blended in order to maintain the shape of the product during use (shape retention). However, if the amount of the wax is large, the spread during application becomes heavy and the gloss exerted by the liquid oil decreases.

 Therefore, because of this contradiction, it is extremely difficult to provide a cosmetic for lips that satisfies both the shape retention and the feeling of use.

[0006] Lip cosmetics with excellent shape retention and usability have long been in the market.

Many researchers are making development efforts.

[0007] In order to solve the above problems, as a wax that gives sufficient shape retention in a small amount, A wax obtained by mixing Fischer-Tropsch wax and microcrystalline wax is used as a shape-retaining agent in stick-shaped solid cosmetics such as lipstick (Patent Document 1).

[0008] However, since Fischer-Tropsch wax has a narrow carbon distribution, there has been a problem that when a lip cosmetic using the Fischer-Tropsch wax is applied to the lips, it feels slippery.

[0009] On the other hand, polyethylene wax is frequently used in lip cosmetics as a wax that is easy to use (Patent Document 2).

 Disclosure of the invention

 Problems to be solved by the invention

 [0010] As a result of intensive studies to solve the above problems, the inventors of the present invention have a crystallization start temperature of 80 to 95 ° C among various polyethylene waxes used for lipsticks and the like. And a wax composition obtained by mixing a specific ratio of microcrystalline wax having a crystallization start temperature of 85 to 100 ° C. gives excellent hardness as a solid agent for stick-like cosmetics. I found it. When this wax composition is blended with an oil containing 30% or more of a relatively highly polar oil having a 10% value of 0.2 or more, the wax composition can be obtained without impairing the good usability unique to polyethylene. The present inventors have found that even if the amount of the product is small, it is possible to produce a stick-shaped cosmetic material having excellent shape retention and excellent glossiness, and the present invention has been completed.

 [001 1] The present invention uses a specific wax composition as a solid agent to give a product with sufficient hardness even with a small amount of blending, there is no problem of crystallization start temperature, and excellent shape retention and The aim is to provide stick-like cosmetics with excellent and smooth gloss.

 Means for solving the problem

[0012] The present invention is as follows. 1: (a) a polyethylene wax having a crystallization start temperature of 80 to 95 ° C;

(b) a microcrystalline box having a crystallization start temperature of 85 to 100 ° C.

 (a): (b) = 99: 1 to 60: contained in a mass ratio of 40,

 (c) A stick-shaped cosmetic comprising 30% by mass or more of a liquid oil having an I OB of 0.2 or more.

[0013] 2: The above stick-shaped cosmetic, wherein the difference in the crystallization start temperature between the component (a) and the component (b) is 10 ° C or less.

 The invention's effect

 [0017] The wax composition comprising the polyethylene wax and the microcrystalline wax used in the present invention functions as an excellent solid agent for a specific polar oil component. As a result, even with a small blending amount, it is possible to impart sufficient hardness to the stick-shaped cosmetic containing the specific polar oil, so that excellent shape retention can be ensured. Furthermore, it is possible to provide a stick-like cosmetic material having an excellent and lustrous appearance.

 Brief Description of Drawings

 [0018] Fig. 1 is a graph showing the hardness of a solid.

 BEST MODE FOR CARRYING OUT THE INVENTION

 Hereinafter, the present invention will be described in detail.

 [0020] "(a) Polyethylene wax having an onset temperature of 80 to 95 ° C"

The crystallization start temperature of the polyethylene wax used in the present invention is 80 to 95 ° C. Yes, more preferably 85-95 ° C.

 If the crystallization start temperature is less than 80 ° C, the solidification power of the oil will be low. When the crystallization start temperature exceeds 95 ° C, the effect of increasing the hardness due to the use of the microcrystalline wax is reduced, and the production of the stick cosmetic is difficult.

[0021] A commercially available polyethylene wax can be used. Specifically, the following commercial products are used.

 “Perforumalen 400/500 / PL, Polywax 400/500” (Besiki _ ■ made by Petrolite Co., Ltd.), “A_C 1 702” (Honeywell Co., Ltd.), “Epollen I N 34 ■ 35” (Eastman (Made by company)

[0022] The blending amount of the component (a) is appropriately determined according to the blending amount of the component (b) so as to satisfy the mass ratio which is a requirement of the present invention.

 It is usually 1 to 20% by mass, preferably 3 to 15% by mass, and more preferably 5 to 12% by mass, based on the total amount of the stick-like cosmetic.

[0023] "(b) Microcrystalline box with a crystallization start temperature of 85 to 100 ° C"

 The crystallization start temperature of the microcrystalline wax used in the present invention is 85 to 100 ° C, more preferably 85 to 95 ° C. When the crystallization start temperature is less than 85 ° C, the effect of addition is small. In addition, when the crystallization start temperature exceeds 100 ° C, the production becomes difficult.

[0024] Commercially available products can be used in the present invention. Specifically, the following commercial products are used.

 “Hi_Mic_2095 / 1090” (manufactured by Nippon Seiki Co., Ltd.), “Bi-Square 1 95 A”, “Star Wax 1 00” (above all the power ■ made by Petrolite Co., Ltd.), “Aster Wax 86 1 8/9508 "(IGI)

[0025] The amount of component (b) is appropriately determined according to the amount of component (a) so as to satisfy the mass ratio that is a requirement of the present invention.

 The amount is usually 0.1 to 10% by mass, preferably 0.3 to 8% by mass, and more preferably 1 to 5% by mass with respect to the total amount of the lip cosmetic.

[0026] The component (a) and the component (b) are: (a): (b) = 99: 1 to 60:40 The wax composition mixed at a mass ratio is used as a solid agent in the lip cosmetic of the present invention.

 A preferable mass ratio is (a) :( b) = 97: 5-70: 30. When the component (a) and the component (b) are mixed at the above mass ratio, the hardness of the sticky cosmetic of the present invention shows a critically very high value. That is, the above-mentioned wax composition exhibits an extremely excellent effect as a solid agent.

 The wax composition may be simply heated by stirring the component (a) and the component (b) at the above mass ratio. This wax composition is preferably blended in the liquid oil as a solid agent for stick-like cosmetics.

 This wax composition has great utility as an alternative to conventional solid agents (especially ceresin frequently used in lipsticks).

 On the other hand, even if (a) component and (b) component are not mixed, the sticky cosmetic is produced by mixing and stirring separately in the liquid oil so as to satisfy the above mass ratio. Good.

[0027] The blending amount of the wax composition The total blending amount of the component (a) and the component (b) is appropriately determined depending on the kind of the sticky cosmetic.

 The content is preferably 2 to 20% by mass or more, more preferably 5 to 20% by mass, and particularly preferably 5 to 15% by mass with respect to the total amount of the stick cosmetic. If the blending amount is less than 2% by mass, it does not function as a solid agent, and there may be a problem in the shape retention of the product.

 If the blending amount exceeds 20% by mass, the product may be too hard or the gloss may be hindered.

 In the present invention, other waxes may be included as long as the effects of the invention are not impaired. The amount thereof is preferably 50% or less with respect to the total amount of component (a) and component (b).

[0028] In the stick cosmetic of the present invention, an oil having an IOB of 0.2 or more is blended in an amount of 300/0 or more, more preferably 400/0 or more, based on the total amount of the stick cosmetic. Otherwise, the effect of the present invention will not be exhibited. I OB has low oil content When used in an amount, even if the amount of the wax composition is large, high hardness cannot be expected. The upper limit is 95%, and about 90% is preferable in terms of molding.

 This wax composition can give a sufficient amount of hardness to a stick-shaped cosmetic even with a small amount. Therefore, it is possible to provide a stick-shaped cosmetic (particularly a lip cosmetic) having excellent shape retention without losing the gloss and gloss caused by the liquid oil.

 Furthermore, there is no problem in the production of stick cosmetics from the viewpoint of the crystallization start temperature.

 [0029] There are no particular limitations on the oil content of I OB of 0.2 or less used in the present invention. For example, the following oils are listed.

 Neopentyl glycol dicaprate, glyceryl tri-2-ethylhexylhexate, pentaerythrityl tetra-2-ethylhexylhexanoate, glyceryl tri (power prill / power purine), cetylhexyl sebacate, octyldodecanol, diisostearic acid Glyceryl, diglyceryl triisostearate, diisostearyl malate, trimethylolyl tri-2-ethylhexylate, oxycysteyl oxystearate, tetra (ethylhexanoic acid / benzoic acid) pentaerythrityl, castor oil.

 [0030] In addition to the above-mentioned oil components having an IOB of 0.2 or less, oil components usually used in cosmetics can be blended.

 The preferred liquid oil content is as follows.

 Dimethylpolysiloxane, Decamethylcyclopentasiloxane, Crude deminut oil, Jojoba oil, Squallane, Liquid lanolin, Tri (hydrogenated rosin-isostearic acid) Glyceryl, Methylphenylpolysiloxane, Glyceryl triisostearate, Polybutene, Polyisobutene.

[0031] In particular, lipstick is preferably blended with liquid lanolin, tri (hydrogenated rosin, isostearic acid) glyceryl, methylphenylpolysiloxane, glyceryl triisostearate, and polybutene.

To improve the makeup of lipstick, volatile liquid oil (octamethylcyclo Cyclic silicone oils such as tetrasiloxane, decamethylcyclopentasiloxane, and dodecamethyl hexasiloxane are also preferred.

 [0032] The blending amount of the liquid oil is usually 30 to 98% by mass, preferably 50 to 95% by mass, with respect to the total amount of the stick cosmetic. When the blending amount of the liquid oil decreases, the spread tends to deteriorate, so that the blending amount is preferably 50% by mass or more.

 [0033] In addition to the liquid oil, if necessary, the stick cosmetic of the present invention may be used in combination with a solid oil or a semi-solid oil.

 [0034] In addition to the above essential components, the stick-shaped cosmetic of the present invention, as long as it does not impair the effects of the present invention, other waxes, other oils, moisturizers, preservatives, oxidation Inhibitors, UV absorbers, polymers, surfactants, dyes, pigments, powders, drugs, alcohols, solvents, and fragrances can be blended as appropriate, and can be produced by conventional methods according to the type of product.

 [0035] The stick cosmetic of the present invention is required to have an appropriate hardness of about 0.1 N to 0.3 N in order to bend and be stable during use. The hardness mentioned here is when a sample left at 30 ° C for 1 hour is measured using a rheometer manufactured by Rheotech Co., Ltd. with a pressure sensitive axis of 10, a penetration speed of 2 cm / min, and a penetration depth of 3 mm. Means the value of.

 [0036] The stick cosmetic of the present invention is not limited as long as it is a solid stick cosmetic having a certain hardness. For example, stick-shaped lip cosmetics such as lipstick, lip gloss, and lip cream; stick-shaped cap cosmetics such as foundation and eye shadow; and stick-shaped hair cosmetics such as hair stick and pomade.

 Lip cosmetics that feel a feeling of use are preferred, and lipsticks that contain a powder colorant are particularly preferred.

 [0037] The stick-shaped cosmetic of the present invention achieves excellent shape retention and feeling of use due to the wax composition comprising the component (a) and the component (b) having a specific crystallization start temperature.

The reason is unknown, but it is assumed as follows. That is, the stick-shaped cosmetic of the present invention has a skeleton in which fine crystals of each wax are connected to each other in a network. The skeleton contains liquid oil and the whole is kept solid.

 Since the structure and properties of stick cosmetics are influenced by the fine crystal structure and size of each wax and the type of liquid oil, the wax composition of the present invention is probably optimal in terms of shape retention and use feeling. Thus, it is assumed that the liquid oil is solidified.

 Example

 Next, the present invention will be described more specifically with reference to examples. The present invention is not limited by the following examples. Unless otherwise specified, the amount is shown in mass%.

 [0039] "Solid: Sax composition"

 The liquid oil was solidified with wax compositions having different crystallization start temperatures and mixing ratios of the component (a) and the component (b). This solid material can be used as it is as a lip balm.

[0040] First, as component (a), polyethylene wax having a crystallization start temperature of 80 ° C and 87 ° C and a comparative example of 97 ° C was used.

 The polyethylene wax used below is as follows.

 "Polyethylene wax (1)" → "Perforumalen 400 (crystallization start temperature 80 ° C)"

 “Polyethylene wax (2)” → “Performalene P L (crystallization start temperature: 87 ° C)”

 “Polyethylene wax (3)” → “Perforumalen 655 (crystallization start temperature 97 ° C)”

 (All made by Peter Light)

[0041] (b) In the case of combining microcrystalline wax (“microcrystalline wax (1)” → “H i _Mic — 1090” manufactured by Nihon Seiki Co., Ltd.) with a crystallization start temperature of 86 ° C as the component Indicates hardness. [0042] Tenax composition 10% by mass and liquid oil with an IOB of 0.2 or more (Tetra 2

—Ethylhexanoic acid pentaerythrityl) The hardness of a solid material obtained by mixing with 90% by mass was measured.

 The hardness meter used was a rheometer made by Rheotech. Samples left at 30 ° C for 1 hour were measured with a pressure-sensitive axis 10, penetration rate 2 cm / min, and penetration depth 3 mm.

[0043] The results are shown in Table 1.

 1

 As is clear from this result, when polyethylene wax having a crystallization start temperature of 80 to 95 ° C. and microcrystalline wax were used in combination, a higher hardness was obtained than when used alone. On the other hand, the crystallization start temperature of the wax composition has no problem in production.

 [0044] Next, the liquid oil was solidified by the use of a wax composition in which the (a) component and the (b) component had different crystallization start temperatures and mixing ratios. The total wax composition was 5.6% by mass, and the hardness of a solid material obtained by mixing 94.4% by mass of a liquid oil (pentaerythrityl tetra-2-ethylhexanoate) was measured.

[0045] As the component (a), a polyethylene wax having a crystallization start temperature of 87 ° C (Perforallen PL manufactured by Becker-Petrolite) was used. As the component (b), microcrystalline wax having a crystallization start temperature of 86, 87, 98 ° C and a comparative example of 80 ° C was used. [0046] The microcrystalline wax used was as follows.

 “Microcrystalline wax (1)” → “Nippon Seiki Co., Ltd. H i -M i c-

1 090 (crystallization start temperature 86 ° C)

 “Microcrystalline wax (2)” → “AGI Waxer 9508 (crystallization start temperature: 87 ° C)”

 “Microcrystalline wax (3)” → “Nippon Seisakusha H i -M i c-

2095 (crystallization start temperature 99 ° C)

 “Microcrystalline wax (4)” → “Multi-wax W-445 manufactured by Witco (crystallization start temperature 80 ° C)”

[0047] The results are shown in Fig. 1.

 From this result, the mixing ratio is (a) :( b) = 99: 1-60: 40, preferably (a) :( b) = 95: 5-60: 40, more preferably (a): (b) It can be seen that the hardness of the solid material (sticky cosmetic) increases dramatically when = 90: 10 to 70:30.

[0048] In addition, when the difference in crystallization start temperature between the components (a) and (b) is 10 ° C or less, a high synergistic effect is obtained, and the above numerical values have a critical significance. .

 On the other hand, the crystallization start temperature of the wax composition has no problem in production.

[0049] "Cosmetics for lips"

 Lipsticks shown in Table 2 were produced and the effects of the present invention were examined.
