Description

[Detailed description of the invention]

[Industrial Application Field] The present invention provides ease of use by blending boron nitride powder,
This invention relates to cosmetics with good finish, long-lasting makeup, stability, and moldability. [Prior Art] Talc, kaolin, mica, titanium dioxide, zinc white, resin powder, etc. are used as extender pigments in conventional cosmetics. The amount of these ingredients to be added is determined by taking into consideration the spreadability, adhesion, covering power, moldability, etc. of the cosmetic. However, cosmetics using conventional raw materials are not always satisfactory in terms of ease of use, finish, makeup retention, stability, moldability, etc. In other words, the conventional concept of extender pigments for cosmetics uses scaly mica and pearl agents to create luster, but when these are blended, moldability deteriorates, which is a drawback. In addition, to improve the lubricity, a powder with a somewhat large particle size is used, but when this is mixed, it feels rough, and spherical resin powders such as nylon powder and polyethylene powder are also used. However, its use had the disadvantage of poor moldability. Furthermore, titanium dioxide and zinc white are added to provide coverage and adhesion, but they have the disadvantage of being difficult to spread. Additionally, mica, talc, and kaolin have catalytic activity and are known to cause deterioration of fragrances and oils, causing odor. [Problems to be Solved by the Invention] In view of these circumstances, the present inventors have conducted intensive research on the usability, finish, moldability, etc. of cosmetics, and have found that cosmetics containing boron nitride powder can be spread easily. We discovered that this cosmetic product has excellent properties such as good adhesion, smooth coverage, gloss, and moldability, and has little deteriorating effect on fragrances and oils. Based on this, the present invention was completed. [Means for Solving the Problems] That is, the present invention is a cosmetic characterized by incorporating boron nitride powder. Hereinafter, the configuration of the present invention will be explained in detail. The boron nitride (BN) powder used in the present invention is h-
Examples include BN, w-BN, c-BN, r-BN, and t-BN. (edited by the Institute of Inorganic Materials, Science and Technology Agency: Research on boron nitride [Inorganic Materials Research Institute Research Report No. 27)
], 1981.) Among them, h-BN shows the best properties. The average particle size of the boron nitride powder is not particularly limited, but it is preferably 0.1 to 30μ in terms of spherical equivalent particle size (measured with a Shimadzu centrifugal sedimentation type particle size distribution analyzer SA-CP2).
If it is finer than 0.1μ, the smoothness will be impaired, and if it is 30μ or more, it will feel rough. Boron nitride powder is blended in the cosmetic composition of the present invention in an amount of about 0.1 to 99% by weight. If it is less than 0.1% by weight, the above-mentioned effects cannot be sufficiently obtained, which is not preferable. In addition to the above-mentioned essential ingredients, other ingredients commonly used in cosmetics can be appropriately blended into the cosmetic of the present invention as required.

Examples include water, alcohol, and thickeners. [Effects of the Invention] The cosmetics containing the boron nitride powder of the present invention can achieve the phenomena of having good coverage, good adhesion, and a feeling of adhesion, which have been considered contradictory phenomena until now. We were able to create a cosmetic that spreads easily, has gloss, has good adhesion, has a smooth finish, has good coverage, has little deterioration effect on fragrances and oils, and has good moldability in the case of powder products. .
