Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a new makeup cosmetic, which has strong water repellency, a light and moderately moisturizing feel, less makeup smearing, good adhesion to the skin, and aging. To provide a makeup cosmetic that prevents makeup from floating, dulling, etc. due to dry skin, prevents caking in the product system, and is light and easy to spread.

Conventionally, commonly available makeup cosmetics, especially loose and! Rest-like makeup cosmetics are characterized by differences in the degree of hydrophilicity and lipophilicity of the powder surface to which it is applied, differences in the degree of activation of the powder surface, and differences in the degree of adhesion to the surface of the powder with weak force or non-uniformity. Usually, the difference in the amount of adsorbed oil and the HLB of the oil causes makeup to smudge and lack a sense of adhesion even when applied to the skin. Among the several types of pigments that are still mixed into powder, differences in the degree of hydrophilicity, degree of lipophilicity, crystal form, surface activity, and wetting phenomenon of the pigment surface due to affinity, As time passes, problems with cosmetic effects such as floating makeup and dullness occur, and the quality of the product is not always satisfactory.

Currently, in the case of pressed make-up cosmetics that can be applied to the skin without using water, the application body (bacterium) is the cosmetic (
If you leave the soap on the surface of the cake (cake) and use it while it is still dirty with sebum or sweat, the oil that has landed on the cake,
Moisture or oil from the base foundation easily penetrates between the particles of the cosmetic and causes caking (a condition where the surface of the cake becomes lumpy), which significantly impairs the product value. When applying cosmetics to the skin, sweat, water, etc. often cause the makeup to fade over time.On the other hand, in the case of pressed makeup cosmetics that are applied to the skin using water, It is composed of an oil-based system that is a mixture of powder and pigment, mixed with oil and a surfactant, and by adding water once a month to this makeup, the water, oil, and surfactant emulsify on the eyes and face. Take advantage of the fact that it is applied to your skin and apply it 11'i 1..

However, oil-based bases containing surfactants tend to solubilize due to interaction with moisture that adheres to the long surface of cosmetics or penetrates into the cosmetic layer over time, resulting in oil content. forms a hard shell structure by encapsulating powder and pigments 1-.
As a result of intensive research, the inventors of the present invention have overcome these drawbacks by creating a makeup makeup product (...1). 1. A composition containing a composition obtained by treating powder such as i-C pigment with a specific water repellent to make it lipophilic and then coating it with a water repellent is 44
The present invention has now been completed by showing that F is suitable for use with or without water when used.

In the present invention, powders such as pigments are made lipophilic by treating them with TreeNone oil of a polymer, and then the treated powders are coated with a water solution of 4Ji and treated with 4+. This is a make-up cosmetic, especially a press-like make-up cosmetic, characterized by containing two or more types of calligraphy (no change in content).This high molecular weight silicone oil has the general formula (1) (in the formula n is 300~2
000, R represents a group selected from a hydrogen atom, a lower alkyl group, a benzyl group, a cyclohexyl group, a naphthyl group, or a furfuryl group).

Furthermore, according to the second aspect of the present invention, the same lipophilicity can be obtained by simultaneously using a methyl water bulk polysiloxane having a degree of polymerization of 40 or less during the lipophilic treatment of the high molecular weight silicone oil. This is possible with a small amount of silicone oil.

According to any aspect of the present invention, a treated powder with improved and uniform water repellency can be obtained compared to conventional methods.
By containing at least one of the following, cosmetics, especially make-up cosmetics (for example, cake-like powder, oil 1, '11, white powder, etc.) which overcome the drawbacks of the conventional methods described above can be obtained.

The high molecular weight silicone oil is selected from the silicone oils represented by the above-mentioned general formula (1), and among them, somethylborinoxano is preferred. ) is n = 300 and η tool 7

It is known to treat powders with silicone oil and to use silicone-treated powders as cosmetics. For example, Japanese Patent Application Publication No. 54. -14528 discloses a cosmetic prepared by processing powder using a low-viscosity silicone oil as a water repellent. The reason why the prior art using high viscosity silicone oil as in the present application has not been seen is because it is difficult to process powder with high viscosity silicone oil, and it is difficult to process powder with high viscosity silicone oil, : This is because the coating becomes non-uniform. Even if the high viscosity Noricone oil of the present application is forcibly treated by the method of JP-A-5J-14528, the coating will not have a uniform VC and the cosmetics will be damaged.・I spreads poorly, is uneven and is 1
4. It is not possible to obtain excellent cosmetics due to
Therefore, it is understood that in the conventional method, a low viscosity silicone oil is used.

The present invention achieves a uniform coating by treating high viscosity silicone oil, which is difficult to apply, in a two-step process of lipophilization treatment and coating, and achieves a moist and moist coating that is the advantage of high viscosity silicone oil. This product succeeded in providing a sense of touch and close contact.

In the present invention, lipophilic treatment refers to preliminary surface treatment of the powder with silicone oil to make the powder surface lipophilic prior to coating the powder.

In this case, using the above-mentioned high molecular weight silicone oil, methyl hydrogen, j5 lysiloxane (methyl H polysiloxane, usually having a concentration of 40 or less) and an organic solvent are used.
That is, for 100 parts by weight of powder, 1 to 10 parts by weight of high molecular weight/licon oil, 4 parts by weight of methylhydrogen polysiloxane are used, and an appropriate amount of organic solvent (for example, 30 to 60 parts by weight) is used.
Mix and stir the mixed solution with the powder for 1 minute using an Elm mixer, Ribo/Bunong, etc. The mixture is then evaporated! 11. It is dried at high temperature to form a lipophilic powder and then sent to the next coating stage [8].

Here, high molecular weight silicone oil is defined by the general formula % formula % (

1 to 4 layers per part of the measuring part; li, preferably increased or decreased depending on the high molecular weight silicone oil, usually 1 to 3 to 0 per part of LL high molecular weight silicone oil. .The fourth part is good.

Due to its polymerizable properties, methylhydrogen polysiloxane does not dry well when dried at high temperatures. It is presumed that this has the effect of remerizing and fixing the high molecular weight silicone oil to the powder surface. Therefore, the use of methylhydrogen polysiloxane in combination with lipophilic treatment produces more favorable results.1 The organic solvent used for lipophilic treatment is one that dissolves silicone oil and is easily distilled off. There are no particular limitations. The amount thereof is not particularly limited, but 2 to 20 parts is usually added to 1 part of silicone oil.

The lipophilized powder (is further coated with a water repellent agent. The coating treatment referred to in the present invention means that a water repellent agent is further attached to the surface of the lipophilized powder, and usually the powder is coated with a water repellent agent. This is done by spraying a water repellent while stirring at high speed.

At this time, the water repellent contains at least the high molecular weight silicone oil of the general formula (1), but it may be the same as that used in the lipophilic treatment or a different one.

In the general formula (1), n is 250 or less! j(1'l'i

As mentioned above, it is difficult to directly surface-treat powder with high-viscosity silicone oil, but it is not necessarily impossible to coat the powder in one step using a mixed oil of low-viscosity silicone and high-viscosity silicone. . However, compared to the two-step method of the present invention, the amount of high viscosity silicone required to achieve the same water repellency is much higher and the feel is also poorer. In the case where dimethylpolysiloxane is used as the low-viscosity silicone oil, 100 parts of powder is treated to make it lipophilic with 2 parts of high-viscosity silicone and 1 part of methylhydrogen polysiloxane, and then 3.5 parts of high-viscosity silicone, The treated powder obtained by the two-step method of the present invention using a mixed oil containing 1.5 parts of low viscosity silicone is obtained by mixing 100 parts of powder with 1.5 parts of low viscosity silicone and 10.0 parts of high viscosity/licone. It has water repellency equivalent to that of powder treated in one stage. It has been found that there is a large difference in the water repellency of the surface when comparing the powders coated in one stage and those treated in two stages with the same amount of silicone oil.
