Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a cosmetic, in particular, a newly created porous powder that is blended with a cosmetic that has excellent fragrance retention, moisture retention, breathability, texture, light resistance, dispersibility, and filling properties. The present invention relates to a skin material that is moist and smooth and has excellent adhesion without causing any strain on the skin.

Conventionally, powders used in cosmetics have a complex crystal growth process, so defects often already occur when the structure is formed by crystallization, especially in natural minerals, for example, due to the atomic arrangement. Due to the randomness of the crystals, the dropout of atoms, and the lack of homogeneity within the crystal, crystals exhibit a structure consisting of a discontinuous collection of blocks, and there are almost no crystals that have an ideal arrangement.

Powders made of natural minerals have the physical properties of ordinary powders, such as elasticity, specific heat, specific gravity, transparency, hardness, electromagnetic properties,
It has unique characteristics such as malleability, heat resistance, virility, and flexibility, and it has various properties depending on its crystal structure, its fineness, and crystal shape. For example, minerals that are scaly and have a three-layer structure have weak connections between the eyebrows and a fully developed penis, giving them a slippery feel and being rich in elasticity. The lack of this is one of the causes of manufacturing troubles. In addition, only a few of the two-layered structures have excellent interlocking properties, and because the crystals are amorphous, close-packed packing is required due to the elasticity of the powder and the fineness of the crystalline form. It is difficult to obtain a structure, poor in filling properties, and at the same time, it is not possible to obtain a material that is satisfactory in terms of sliding feel. On the other hand, natural minerals contain water and impurities,
There are also sensitive types that are affected by the generation conditions and non-sensitive types that are not affected. There are three types of water in a crystal structure: free water, attached water, adsorbed water, and bound water.
Adhered water and adsorbed water are easily desorbed, attached, or adsorbed depending on external conditions, and in particular, when adsorbed water is desorbed, the crystal structure changes. As can be understood from the above, most natural minerals inherently have low heat retention properties.
Viewed from a structural standpoint, it is proven that natural minerals have the disadvantage that they have a low ability to retain moisture and fragrance, and the fragrance of the fragrance weakens over a short period of time. In addition, most natural minerals have a one-, two-, or three-layer structure, but since they do not have porosity, they have poor breathability, so they are often mixed with IQ shoyo and applied to the skin. When this occurs, it tends to impede the skin's ability to breathe, causing stress on the skin. The present invention solves the conventional problems as described above and provides cosmetics with excellent properties.

That is, the cosmetic according to the present invention contains anhydrous silicic acid compound, aluminum/
A coating material consisting of one or more fine powders of a silicic acid compound, a magnesium silicate compound, a metal carbonate compound, an anhydrous aluminosilicate compound containing a volatile component other than water, a low-emitting substance, or one or two combustible substances. It is characterized in that a porous powder obtained by adhering and aggregating on the surface of an inner core material consisting of a fine powder of more than 100% is blended into the ionizing material component.
Hereinafter, to explain the details of the present invention in detail, first, preferred specific examples of natural minerals constituting the coating material of the porous powder are as shown in the table below. Use one type or a mixture of two or more types. Next, the metal carbonate compounds that make up the inner core material include magnesium carbonate, beryllium carbonate, calcium carbonate, ferric carbonate, barium carbonate, manganese carbonate, lithium carbonate, cobalt carbonate, magnesium potassium hydrogen carbonate, strontium carbonate, carbonate Examples include lithium hydrogen, zinc carbonate, and chromium carbonate. Examples of metal carbonate compounds existing as natural minerals include dolomite, calcite, aralite, strontianite, munganite, and dokujudoite.

Examples of anhydrous aluminosilicate compounds containing volatile components other than water include amphibole, biotite, jadeite, dumolychieflite, and zunite, which lose their volatile components when heated and easily transform into mullite, increasing their volume. Minerals that contract and expand when heated, such as pearlite, blackstone, and pinestone, are undesirable and should not be used. In addition, the volatile substances preferably have an average particle size of 1 to 50 French, and include menthol, camphor, methyl/graben, ethyl/graben, propyl/graben, butylparaben, naphthalene, sulfurobic acid, dehydroboric acid, etc. , benzoic acid, salicylic acid, cinnamic acid, parachlorobenzoic acid, paraoxybenzoic acid, etc.Furthermore, flammable substances include nylon, polystyrene, Teflon, polyethylene, polypropylene, polyolefin, Delrin, and distylbenzene pinhole polymer. , synthetic resins such as benzoguanami powder, copolymers thereof, starch, carbon, sulfur, etc., and these are preferably spherical or porous spherical.

When producing the porous powder used in the present invention, the weight ratio of the coating material and the inner core material is about 8:2 to 1:9, and it is preferably 700 to 7
When worshiped under a reduced pressure of about 60 Hg, an adsorbed ion layer is formed on the surface of the inner core material, and the negatively charged minerals that are the coating material are attracted to these layers, causing the coating to adhere and coagulate on the surface of the inner core material. As a result, a cored porous powder containing an inner core material having an average particle size of about 1 to 50 mm is produced.

Moreover, such porous powders can also be produced using an inert solvent instead of in an aqueous system. In this case, the weight ratio of the coating material and the inner core material is 8:2 to 2:8, and the weight ratio of the coating material, the inner core material, and the inert solvent is 9:2 to 2:8.
:1 to 6:4, preferably 8.3:1.7. Examples of inert solvents include silicone oil, polybran, polyoxyethylene tall oil derivatives, etc. The coating material and the inner core material are added to these inert solvents, and the mixture is preferably heated to about 700 to 760 legs Hg at room temperature. When the coating material and the inner core material are surrounded by an inert solvent and physically united under reduced pressure, a cored porous powder can be obtained by passing them through a suction furnace. be. Next, when this powder is dried or fired by heating at about 50 to 150,000 in an oxidizing gas flow for about 1 to 24 hours, the particles of the fine powder constituting the coating material will firmly bind to each other, and at the same time, the inner core material will also bond to each other. It becomes a powder that binds tightly and does not easily shatter. If the inner core material contains a volatile substance, it will volatilize during heating, and if it further contains a metal carbonate compound, it may contain hydrochloric acid, nitric acid, sulfuric acid, etc. at a concentration of about 1 to 2% by weight. This can be melted by washing with an acid solution to form a semi-hollow cored porous powder. In addition, if the inner core core material contains a combustible substance, especially a synthetic resin, the coating material and the inner core core material are mixed in a ratio of 7:3 to 3:7 in the Takaazusa crusher of a centrifugal ball mill. Unique frictional mixing is performed to grind only the coating material and further refine it, and at the same time, the inner core material is charged by friction, and the finer coating material is adhered and aggregated on the surface of the inner core material.

Next, this cored porous powder was placed in oxidized gas and sulfur under normal pressure for 15 minutes.
By gradually increasing the temperature between 0 and 1,600 degrees Celsius, the combustible material is burned and the fine powder particles that make up the coating material are firmly bound to each other, creating a semi-hollow cored porous structure that does not easily shatter. It can be made into a powder. Furthermore, anhydrous aluminum whose inner core material contains volatile components other than water
