Abstract

PURPOSE:The titled cosmetic that contains a hydrophobic powder which has been prepared by treating an inorganic or organic powder and a non-reactive high-viscosity silicone oil mechanochemically or with a roll mill, thus giving appropriately moist feeling with very little makeup collapse. CONSTITUTION:At least one selected from inorganic powders such as silicic acid, talc and titanium dioxide and organic powders such as polyamide, spherical cellulose powder is treated with a high-viscosity silicone oil of the formula (R is lower alkyl, phenyl; n is integer of 300-2,000) mechanochemically or by means of a roll mill to prepare a hydrophobic powder. The resultant powder is mixed in an amount of 1-99wt% to give a makeup cosmetic. The cosmetic has high water repellency, good moist feeling and good adhesion to skin. The viscosity of the silicone oil is preferably 600-1,000,000cst.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a makeup cosmetic containing hydrophobized powder. More specifically, the present invention relates to a makeup cosmetic containing a hydrophobized powder obtained by mechanochemically processing or roll milling a high viscosity silicone oil and powder.

[Prior Art] There have been many known methods for making hydrophilic powders hydrophobic, and in particular, it is already well known to utilize the hydrophobic properties of silicone oil.

The present inventors first homogeneously mixed and ground metal hydroxide, which is a catalyst for initiating crosslinking polymerization of reactive silicone oil, into various hydrophilic powders, and then methyl hydroxide having a predetermined amount of reaction activity. We have discovered a method for producing hydrophobic powder by mechanochemically forming cross-linked polymers on the powder surface without special heat treatment of hydrogen polysiloxane (Japanese Patent Publication No. 56-43
264).

Furthermore, Japanese Patent Publication No. 59-36881 reports a pressed makeup composition containing low viscosity silicone oil as a water repellent.

[Problems to be Solved by the Invention] The powder obtained by the method of Japanese Patent Publication No. 56-43264 has no discoloration and does not contain any single silicone resin lumps. Although it was an excellent hydrophobic powder, if the reaction of the organohydrogenpolysiloxane on the powder is not sufficient, the reaction may proceed roughly over time, resulting in a change in hydrophobicity. There were also cases where moldability deteriorated when forming into a solid foundation.

This phenomenon was unavoidable to varying degrees as long as reactive silicone oils such as organohydrogenpolysiloxane were used.

In addition, non-reactive silicone oil is also used in Japanese Patent Publication No. 59-36881, but because it is a low-viscosity silicone oil, it has less water repellency than when using reactive silicone oil such as organohydrogen polysiloxane. It had the disadvantage of being inferior.

[Means for Solving the Problems] As a result of extensive research in order to improve these drawbacks, the inventors of the present invention have conducted mechanochemical treatment or roll mill treatment of a specific non-reactive high viscosity silicone oil and powder. When the powder obtained by this process is blended into makeup cosmetics, it has excellent water repellency, does not change its hydrophobicity (water repellency) over time, has little makeup fading, has good adhesion to the skin, and is moderately moisturized. The inventors have discovered that a makeup cosmetic with a pleasant feel can be obtained, and based on this knowledge, they have completed the present invention.

That is, the present invention provides one or more powders selected from the group consisting of inorganic powders and organic powders, expressed by the following general formula (where n is an integer from 300 to 2000, and R is the same or different). The present invention provides a makeup cosmetic composition, which is characterized in that it contains a hydrophobized powder obtained by treatment with a high viscosity silicone oil represented by the following formula (which may represent a lower alkyl group or a phenyl group).

(Margin below) The configuration of the present invention will be described below.

The high viscosity silicone oil used in the present invention is a silicone represented by the following general formula (in the formula, n is an integer of 300 to 2000, R's may be the same or different and represent a lower alkyl group or a phenyl group). It is an oil with a viscosity of 600~
It is 1,000,000cst.

If the viscosity of the silicone oil is less than 600 cst, the silicone oil processed into powder will dissolve into other oils in the cosmetic, resulting in a decrease in water repellency, which is not preferable.

Moreover, if it exceeds 1,000,0OOcst, the viscosity is too high and it becomes sticky when handled, which is not preferable.

High viscosity silicone oil is 0.1 to 20% by weight in powder form.
It is used in a range of 1 to 10% by weight, particularly preferably 1 to 10% by weight. If it is less than 1% by weight, water repellency tends to be poor, and if it exceeds 20% by weight, it tends to become sticky.

The powders used in the present invention include silicic acid, silicic anhydride, magnesium silicate, talc, kaolin, mica, bentonite, titanium-coated mica, bismuth oxychloride, zirconium oxide, magnesium oxide,
Zinc oxide, titanium dioxide, aluminum oxide, calcium sulfate, barium sulfate, mu, magnesium sulfate, calcium carbonate, magnesium carbonate, iron oxide, ultramarine, deep blue, chromium oxide, chromium hydroxide, calamine and carbon black, and complexes thereof, etc. inorganic powders, and polyamides, polyesters, polyethylene, polypropylene, polystyrene, polyurethane, vinyl resins, urea resins, phenolic resins, fluororesins, silicone resins, acrylic resins, melamine resins, epoxy resins, polycarbonate resins, divinylbenzene and styrene. Copolymer, copolymer consisting of two or more monomers of the above compounds, celluloid, acetylcellulose, cellulose, polysaccharide, protein, hard protein, CI pigment yellow, CI pigment orange, CI pigment red, CI pigment violet , CI Pigment Blue, CI Pigment Green, and CI Pigment Brown, and one or more of them can be selected and used.

Further, the shape of the above powder is not particularly limited, and may be plate-like, lump-like,
Of course, any shape can be used, including scaly, spherical, and porous spherical shapes. Moreover, both porous and non-porous materials can be used.

The mechanochemical treatment used in the present invention specifically refers to treatment using a ball mill, hodgersite ball mill, vibrating ball mill, vibrating rod mill, vibrating mill, attritor, bot mill, rod mill, pan mill, crusher, etc. The roll mill treatment used in the present invention involves kneading with shear using a roll mill such as a two-roll or three-roll mill, and both are particularly excellent methods for uniformly mixing high-viscosity silicone oil. be.

Further, before and after these hydrophobizing treatments, mixing and stirring may be performed using a Henschel mixer, a ribbon blender, a Nauta mixer, or the like.

The amount of the hydrophobized powder thus obtained in the makeup cosmetic according to the present invention is usually about 1 to 99%.

[Effects] The present invention mechanochemically processes high viscosity silicone oil, which has excellent water repellency and usability but is difficult to apply due to its non-reactivity, thereby making it possible to uniformly coat powder. The product successfully achieved the moist, soft feel, adhesion, and water repellency that are the advantages of high-viscosity silicone oils. Furthermore, since there is no need to use an organic solvent, there are no disadvantages that occur when using organic solvents.

By the production method of the present invention, hydrophobic powder coated with silicone resin can be used as powder for cosmetics, inorganic additives for plastics (reinforcing agents, colorants, etc.), inorganic additives for rubber, magnetic tapes (magnetic iron oxide), It can be widely used in paints, inorganic pigments for ink, lubricants, etc.

The invention will now be explained in more detail by way of examples.
