Definitions
- the present invention generally relates to surface-treated powders obtained by surface-treating base powders, and specifically relates to surface-treated powders used in cosmetics.
- Patent Document 1 it has a high SPF value, does not impair the feel and feeling of use peculiar to oil-in-water emulsified cosmetics, and has a film (cosmetic film) (A) a carboxylic acid-modified silicone liquid at 50 ° C., (B) a vinyl polymer emulsion, (C) a basic compound, and (D) an oil-in-water emulsified cosmetic containing an inorganic UV protective agent comprising a hydrophobic fine particulate metal oxide.
- A a carboxylic acid-modified silicone liquid at 50 ° C.
- B a vinyl polymer emulsion
- C a basic compound
- D an oil-in-water emulsified cosmetic containing an inorganic UV protective agent comprising a hydrophobic fine particulate metal oxide.
- Patent Document 2 a specific A surface-treated powder obtained by using an organosiloxane derivative having a structure as a surface-treating agent and treating the surface of the powder with the organopolysiloxane derivative and a cosmetic containing the same are described.
- an object of the present invention is to provide a surface treatment for blending in a cosmetic that is capable of forming a cosmetic film with a soft feel and that is capable of preventing mask transfer of makeup to an extent equal to or greater than that of conventional methods. It is to provide the powder.

＜化粧方法＞
本発明の化粧料を用いて化粧をする場合、表面処理粉体を含む化粧料を肌に塗布して化粧膜を形成した後、化粧膜に水分を付着させる。例えば化粧料としてパウダーファンデーションに本発明の表面処理粉体が配合される場合、通常のパウダーファンデーションの塗布方法が行われ、肌に化粧膜が形成される。化粧膜に水分を付着させる方法は限定されないが、好ましくは、常温の水をスプレーして、化粧膜全体に均一に水分を付着させる。水分を付着させることによって、カチオンを介して粉体が皮膜を形成し、マスク移りを低減することができる。好ましくは水分を付着させた後、マスクを着用する前に室温で５分間、乾燥させる。 <Makeup method>
When applying makeup using the cosmetic of the present invention, the cosmetic containing the surface-treated powder is applied to the skin to form a cosmetic film, and then water is applied to the cosmetic film. For example, when the surface-treated powder of the present invention is blended into a powder foundation as a cosmetic, a normal powder foundation application method is carried out to form a cosmetic film on the skin. Although the method for applying moisture to the cosmetic film is not limited, it is preferable to spray room temperature water to uniformly apply moisture to the entire cosmetic film. By adhering moisture, the powder forms a film via cations, which can reduce transfer to the mask. After applying moisture, the mask is preferably dried for 5 minutes at room temperature before donning.

人工皮革上の６ｃｍ×３．５ｃｍの範囲に粉体２ｍｇ／ｃｍ２を塗布した。スプレーで水を１５ｃｍ程度離した状態で２秒程度噴霧し、６０℃で１０分乾燥させた。このときの水の噴霧量は１ｇであった。得られた塗布膜上に、黒色のポリエステル布、さらにその上にガラス板を置き、さらにその上から１ｋｇの分銅を置いて１０秒間放置した。色差計により、塗布膜と接触させた黒色ポリエステル布の明度（Ｌ１）と、塗布膜に接触させる前の黒色ポリエステル布の明度（Ｌ２）を測定し、Ｌ１／Ｌ２の値を算出した。Ｌ１／Ｌ２が１に近いほど、色移りが抑制できていると言える。結果を表１に示す。 <Evaluation of mask transfer of surface-treated powder>
2 mg/cm 2 of powder was applied to an area of 6 cm x 3.5 cm on the artificial leather. Water was sprayed for about 2 seconds at a distance of about 15 cm and dried at 60° C. for 10 minutes. The spray amount of water at this time was 1 g. A black polyester cloth was placed on the resulting coating film, a glass plate was placed thereon, a weight of 1 kg was further placed thereon, and left for 10 seconds. The lightness (L1) of the black polyester cloth in contact with the coating film and the lightness (L2) of the black polyester cloth before contacting the coating film were measured by a color difference meter, and the value of L1/L2 was calculated. It can be said that the closer L1/L2 is to 1, the more the color migration is suppressed. Table 1 shows the results.
