Abstract

PURPOSE:A cosmetic having improved utility, finish, durability of makeup, good stability and moldability, obtained by blending a cosmetic with boron nitride powder. CONSTITUTION:A cosmetic obtained by blending a cosmetic with about 0.1-99wt% boron nitride (BN) powder (h-BN, w-BN, c-BN, r-BN, t-BN, etc., most preferably h-BN among them, having preferably about 0.1-30mu average particle diameter calculated a sphere). Addition of the boron nitride powder can produce a phenomenon that good spread and adhesive feeling exist even with covering power, which was regarded as an exclusive event, to give a cosmetic having good spread, luster, improved adhesivity, smooth finish, low deteriorating effect on perfume and oil, providing good moldability in case of powdery product.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a cosmetic containing boron nitride powder, which has good usability, finish, cosmetic wearability, 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 factors such as spreadability, durability, covering power, and moldability 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. That is, the conventional concept of extender pigments for cosmetics uses scaly mica or pearl agents to create luster, but the drawback is that moldability deteriorates when these are blended. In addition, in order to improve the lubricity, a powder with a certain large particle size is used, but if this is mixed, the rough texture will be reduced, and spherical resin powder such as nylon powder or polyethylene powder is used. etc. have also been used, but their use has the disadvantage of poor moldability. Rough coverage,
Titanium dioxide and zinc white are added to give a good adhesion, but they have the disadvantage of being difficult to spread. Additionally, mica, talc, and kaolin have catalytic activity and are known to cause the deterioration of fragrances and oils, causing discoloration and odor.

[Problems to be solved by the invention] In view of these circumstances, the present inventors have attempted to improve the usability of cosmetics,
As a result of intensive research on finish, moldability, etc., we have found that cosmetics containing boron nitride powder spread well, have good adhesion, are smooth, have coverage, are glossy, have good moldability, and have a smooth texture. The present inventors have discovered that the present invention is a cosmetic with excellent properties that have little deteriorating effect on fragrances and oils, and based on this knowledge, they have completed the present invention.

[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.

-BHSc-BN, r-BNs t-BH, etc. (edited by Science and Technology Agency Inorganic Materials Research Institute: Research on boron nitride [Inorganic Materials Research Institute Research Report No. 27], 1981.
) Among them, h-BN shows the most excellent properties.

The average particle size of the boron nitride powder is not particularly limited, but the average particle size in spherical terms (Shimadzu centrifugal sedimentation type particle size distribution analyzer 5A-CF
2) is preferably 0.1 to 30μ. If it is finer than 0.1μ, the smoothness will be impaired, and if it is more than 30μ, it will feel rough. The boron nitride powder is 0.1 to 9 in the cosmetic of the present invention.
9 weight x weight x units. If it is less than 0.1% by weight, the above-mentioned effects cannot be sufficiently obtained, which is not preferable.
