Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel makeup cosmetic composition obtained by containing a propellant.

To explain in more detail, the present invention is a novel product that has excellent finishing effects such as hiding power, texture, and vividness of color, has good adhesion and makeup retention, and is easy to use and has an excellent feeling of use. It is an object of the present invention to provide makeup cosmetics, particularly slow-foaming aerosol type makeup cosmetics.

Traditionally, makeup cosmetics have come in many different types depending on the purpose and characteristics, such as lotion, cream, gel, press, pencil, and stick. Non-aqueous powder dispersion, aqueous powder dispersion, etc. were widely known.

Among these makeup cosmetics mentioned above, the amount of coloring material in the makeup cosmetics is generally 5 to 20% for lotion-like, cream-like, and gel-like types such as foundations and under-makeup products. Items in the weight range of 100 to 100 yen have no center metal, and for pressed, pencil, and stick type items such as pressed powder and solid eye shadow, the amount of coloring material is in the range of 70% by weight or more. is selected next.

In recent years, the desire for makeup cosmetics has diversified,
For example, the types of colorants are mainly used to improve concealing power such as covering and ultraviolet ray blocking effects, to expand textures such as gloss, nozzle, and border feeling after application, and to improve makeup effects such as vividness of colors. improvement of properties that depend on the type and amount of the so-called binder ('i!!
Improvements in comfort (feel on the skin, makeup retention, etc.) have become desirable.

However, in conventional make-up cosmetics, especially lotion-like, cream-like, and gel-like make-up cosmetics, in order to satisfy the above-mentioned needs, the coloring material t' is used at a higher concentration than before (e.g., 20 weight tS or more). ), or the colorant tray is the same as before, but the system contains a film-forming agent such as water-repellent waxes, resins or resin emulsions, or a combination of volatile hydrocarbons and solid oils. Although it is possible to improve the concealing power, texture, makeup effect, and makeup persistence when it is included, on the other hand, the ease of use such as ease of spreading during application and adjustment of the amount used can be improved. This often leads to a decrease in the elasticity of the product, a worsening of the feeling of use such as heavy elongation and a strange feeling, and even problems with the finishing effect such as unevenness and thickness. This was particularly noticeable in relatively wide areas such as the face and body (including hands and feet).

Resolving these contradictory properties in makeup cosmetics is a major challenge for engineers, but until now no decisive means has been found. The reality is that the amount of drugs used is still limited.

Therefore, the present inventors have solved all of the above conventional problems, and have achieved a finishing effect without being restricted to cream-like, gel-like, etc. types.
A new t that achieves both long-lasting makeup, ease of use, and feeling of use.
As a result of intensive research in order to obtain a formulation that is suitable for the skin, we have developed makeup cosmetics, mainly emulsion type and liquid crystal type, that contain a foaming base consisting of a foam forming agent and a propellant.
Without impairing the original makeup function, the foaming base gives a mousse-like appearance when used, spreads well, spreads well, and spreads evenly after application. - and found that it can provide an excellent finishing effect,
The present invention has now been completed.

That is, the makeup cosmetic of the present invention comprises (a)
Color Material 3-60% by weight
(b) Higher alcohol 0051
0% by weight (c) Liquid oil content
5-60% by weight (d) Water and/or polyhydric alcohol 3-90% by weight (e) Surfactant
01-10% by weight (f) Film forming agent 0-40% by weight (
g) Propellant 1~
The present invention relates to a makeup cosmetic characterized by being composed of 10-fold TES.

The present invention will be explained in detail below.

First, the coloring materials applied to the present invention are powders and pigments normally used in makeup cosmetics, specifically titanium dioxide, Merck, kaolin, sericite, bentonites, mica, and titanium. Examples include mica 1, zinc oxide, iron oxide, nylon powder, polyethylene powder, organic pigments, etc., as well as lipophilic or hydrophilic surface treated products, among which one type can be used as appropriate depending on the purpose. Or two or more types are selected and used.

The blending amount is selected to be 3 to 60% by weight, preferably 20 to 40% by weight based on the total amount of the makeup cosmetic. If the amount is less than 3% by weight, the concealing power and make-up effect of the resulting makeup cosmetic will be poor, which is undesirable.On the other hand, if it exceeds 60% by weight, the feeling of use will not be improved due to the function of the foamed base material. However, if this limit is exceeded, good makeup cosmetics cannot be obtained.

Next, the higher alcohol is a liquid crystal forming agent and is added as one of the foaming base materials, a so-called foam forming agent, and those having a carbon number of 16 to 22 are advantageously used. Specifically, cetanol, cetostearyl alcohol, stearyl alcohol, behenyl alcohol, etc. can be used and can be appropriately selected depending on the state of formation of the foam.
It is also possible to use one type or a combination of two or more types.The physical properties of the foam are affected by the carbon number of the higher alcohol, and as the carbon number increases, the foam becomes harder, so if the carbon number is extremely large, If the higher alcohol is used all around, the ease of use and feeling of use may deteriorate, and the finishing effect may be impaired. That is, the purpose of the present invention is based on the premise that when applied, the foamed base material acts to create a mousse-like appearance to improve the feeling of use, and after application, the foam quickly disappears, resulting in a normal make-a-soge cosmetic. Therefore, the foam is required to have appropriate hardness. For the same reason, higher alcohols with a small number of carbon atoms are also not suitable for the present invention.
05-10% by weight, especially when aiming at liquid crystal formation, 0
．． A range of 5-3% by weight is selected.

If the amount is less than 0.05% by weight, the foam forming power will be insufficient, and if the amount exceeds 10% by weight, the foam forming power will be insufficient, as in the case of the above-mentioned carbon number size. Unfavorable in this respect.

Furthermore, in addition to the higher alcohol, higher fatty acids having 12 to 22 carbon atoms, particularly those having 18 to 22 carbon atoms, may be used as foam forming aids in combination with safety. Specifically, there are lauric acid, myristic acid, paramitic acid, stearic acid, arachidic acid, and behenic acid.

Next, the liquid oil is selected based on its compatibility with the film-forming agent described later, pigment dispersibility, emulsifying properties, and feeling of use. For example, hydrocarbons such as squalane and liquid paraffin, low boiling point hydrocarbons, volatile oils such as cyclic silicone, esters such as octyldodecyl oleate and isopropyl myristate, avocado oil, castor oil,
Examples include oils and fats such as mink oil. The amount of the liquid oil itself can be freely adjusted within the range of 5 to 60% by weight, preferably 10 to 20% by weight, depending on the balance with other ingredients, the suitability of emulsification conditions, and the degree of desired makeup function. obtain. For example, when obtaining makeup that has a powdery feel, liquid oil/colorant≦1
The amount of liquid oil may be adjusted within a range such that:

In the present invention, polyhydric alcohols may be used alone or in a mixture of two or more at any ratio in the water bath for preparing emulsified systems and liquid crystal systems. Polyhydric alcohols used include 1,3-butyleg')col, ethylene glycol, furopylene gellicol, polyethylene glycol, glycerin, polyglycerin, arabit, sorbitol, sorbita/, mannitan, malpit, maltose, xylit, glucose. , maltitol, sucrose, lactose, pentaerythritol, etc., but especially when liquid crystal formation is taken into account, glycerin is preferred. The emulsion type of these water or polyhydric alcohols is vO type or O/W type, the emulsion type is 0/polyhydric alcohol type, or even liquid crystal type. Depending on the crab, 3-90!1% preferably 5-2
It can be freely selected within the range of 0% by weight.

Next, surfactants are added as emulsifiers, liquid crystal forming agents, pigment dispersing and stabilizing agents, and examples include W, 10j,
, 0(/Depending on the W type, etc., polyglycerin esters,
Nonionic surfactants such as glycerin pyroglutamic acid monofatty acid esters, polyglycerin ethers, polyoxyethylene alkyl ethers, polyoxyethylene hydrogenated castor oil esters, sorbitan fatty acid esters, sucrose fatty acid esters, and higher fatty acids. Anionic surfactants including alkali salts, triethanolamine salts, etc. may be used alone or in combination of two or more thereof, or as a mixture. still.

When attempting to form a liquid crystal, one having an HLB of 9 to 18 is selected. In addition, the compounding amount is 0.1 to 10% by weight based on the total amount of makeup cosmetics, approximately 5 to 20% by weight as an emulsifier based on the oil agent, and 0.1% by weight as a colorant dispersant based on the colorant. A range of 5 to 3 weight is a suitable target. If the amount is less than 0.1% by weight, emulsification, liquid crystallization, and dispersion will be insufficient, making it impossible to obtain a makeup cosmetic with good pH.
Even if the amount exceeds 10% by weight, it will not have a positive effect on emulsification, liquid crystallization, or dispersion, and from the viewpoint of safety, it is better to avoid 90,000%.

Film-forming agents are used as needed to improve the adhesion of makeup cosmetics and make-up adhesives, and examples of such agents include solid to semi-solid oils. For example, beeswax, oshikerite, solid paraffin, microcrystalline wax, lanoli/carna lano wax, ceresin, candelilla wax, polywax (polyethylene powder), spermaceti wax, etc., or polymer film forming agents such as acrylic copolymer resin, One or two of ethyl acrylate polymer, acrylic resin emulsion, vinyl pyrrolidone/vinyl acetate copolymer, polyacrylic acid amide, etc., or natural/synthetic water-soluble polymers such as carboxyvinyl polymer, polyvinyl alcohol, xanthine gum, latex, etc. They are used in combination or as a mixture of two or more species.

The amount to be blended is determined depending on the film properties (strength, plasticity, etc.) of each film-forming agent. It must be hard enough to flow out of the nozzle. In other words, if the coloring material T-20 is contained in an amount of 41% or more by weight, the ease of use and feeling of use will deteriorate.
Even under the 0 weight range, the film forming agent is about 30 weight or more (there may be some variation depending on the type of film forming agent)
If it is contained, high viscosity or gelation will occur, and it will be difficult to obtain a product that is easy to use and has a good feeling when used without the function of the foamed base material. Furthermore, the amount of film forming agent is 40]i
If it exceeds t%, even with the function of the foamed base material, it will not be possible to obtain a good product that can resist gelation of the makeup cosmetic.

Finally, propellants that can be used in the present invention include propane (bp-42°C), Freon 12 (bp-30°C), n
- Pig 7Cbp - 0,5℃), Freon 114 (bp3
, 6℃], freon 11 (bp 23℃), n-pentay
(bp 36°C), Freon 113 (bp 47°C), etc., and these are preferably used alone or in combination as a propellant having a boiling point in the range of 20 to 30°C. When a propellant in such a temperature range is used, although it is slightly affected by the external environmental temperature depending on the season, the makeup cosmetic of the present invention remains stable and creamy when sprayed, and is easy to apply to the skin. When the skin temperature is 32° C., foaming starts with a delay time of several seconds to several tens of seconds, although it varies depending on the viscosity and hardness of the composition. -1 The amount of propellant blended is 1 to 10% by weight based on the total amount of makeup cosmetics, although there is some variation in the gas volume after oxidation due to differences in the specific gravity of the propellant. range is selected.

In addition, the specific gravity of the makeup cosmetic after foaming is 1/1 of that before foaming.
It is preferable to set the amount of propellant to be 10 or less for the effectiveness of use. If the amount is less than 1% by weight, foam formation will be insufficient, whereas if the amount is more than 10% by weight, residual gas will remain in the makeup cosmetic after foaming, which is undesirable.

In addition to the above, various ingredients that are usually incorporated into makeup cosmetics, such as fragrances, preservatives, or raw materials such as medicinal ingredients, chelating agents, humectants, and ultraviolet absorbers may be added as necessary.

The makeup composition of the present invention is prepared using the various ingredients described above, but there are no particular restrictions on the manufacturing method, such as general O/W emulsification, W10 emulsification, liquid crystallization, dispersion, etc. It is carried out by means of =9. That is, an emulsified or liquid crystal composition can be obtained simply by preparing an aqueous phase containing powder and an oil phase from various substances selected according to various components except the propellant, and mixing them in a stirrer. A surfactant is added to polyhydric alcohol containing water to form a continuous surfactant phase, and after cooling, powder and then an oil phase are added to this.
Furthermore, it can also be produced by diluting with water if necessary. Here, when the amount of water added is within a range of approximately 15% by weight relative to the amount of polyhydric alcohol, the composition gradually shifts to a liquid crystal composition, and as the water increases, it gradually shifts to a soft-coat type emulsion composition.

Next, two methods can be used to emulsify, liquid crystallize, or mix the dispersed composition with a propellant, depending on the properties of the composition. When using fluid materials such as emulsions, the same method as for ordinary aerosol filling is used; however, when using hard materials such as creams, heating or shaking is performed after filling the composition with gas. It is necessary to thoroughly mix the propellant into the composition while exhibiting fluidity.

Here, the characteristics of the makeup cosmetic of the present invention are as follows.

(1) In makeup cosmetics mainly based on emulsion, liquid crystallization, and dispersion systems, the amount of coloring material can be selected from a wide range, so desired hiding power, texture, and color vividness can be imparted.

(2) Similarly, it is now possible to add more film-forming agents than before, and it is possible to obtain makeup cosmetics that have the desired water resistance, adhesion, makeup retention, and other makeup durability.

(3) Furthermore, it has a mousse-like appearance when applied, and spreads easily.
It spreads easily, the amount of application is easy to adjust, and after application, a uniform finish with no unevenness or thickness can be obtained.

Next, the results of evaluating the makeup cosmetics of the present invention will be shown.

The evaluation method was based on the under make-up composition and foundation of the present invention shown in Examples and 2 below, and the under make-up after removing higher alcohols and propellants (increasing the amount of water) from Examples 1 and 2 below as comparative products.
