Description
本発明は、耐移り性に優れたリップコート化粧料に関する。より詳しくは、優れた耐移り性を発揮することに加え、つやがあり、皮膜感を感じさせないリップコート化粧料に関する。
The present invention relates to a lip coat cosmetic excellent in transfer resistance. More specifically, it relates to a lip coat cosmetic that exhibits excellent transfer resistance, is glossy, and does not give a feeling of film.
口紅等のメーキャップ化粧料においては、塗布した化粧料がカップ等に接触することにより転写されてしまう色移り（二次付着）が問題となっていた。昨今の新型コロナウイルス感染症（ＣＯＶＩＤ－１９）の感染拡大を受けて、外出する際や人と面会する際にマスクを着用することが新たな日常（ニューノーマル又はニュースタンダード）になりつつある。従って、口紅等がマスクに二次付着して色落ちすることを防止するため、耐移り性（二次付着レス効果）を向上させることが新たな課題となっている。
With makeup cosmetics such as lipstick, color transfer (secondary adhesion), which is transferred when the applied cosmetics come into contact with a cup or the like, has become a problem. Due to the recent spread of the new coronavirus infection (COVID-19), wearing a mask when going out or meeting people is becoming a new normal (new normal or new standard). Therefore, in order to prevent secondary adhesion of lipstick or the like to the mask and color fading, it is a new issue to improve transfer resistance (secondary adhesion resistance effect).
耐移り性を向上させる手段として、口紅等のメーキャップ化粧料自体に耐移り性を付与する以外に、口紅等の上に重ねて塗布することにより耐移り性を付与するリップコート化粧料（「口紅オーバーコート」ともいう）を用いることが知られている。従来のリップコート化粧料は、撥水性や撥油性の油分に皮膜剤や粉末を配合し、口紅層の上に皮膜層を形成することにより二次付着を防止するものであった（特許文献１）。このようなリップコート化粧料は、二次付着は抑制できても塗布後の皮膜感は避けられず、仕上がりがマットになり「つや」が失われることがあった。
As a means to improve transfer resistance, in addition to imparting transfer resistance to makeup cosmetics such as lipstick itself, lip coat cosmetics that impart transfer resistance by coating on top of lipstick etc. It is known to use a "overcoat"). Conventional lip coat cosmetics prevent secondary adhesion by blending a film agent or powder with a water-repellent or oil-repellent oil component to form a film layer on the lipstick layer (Patent Document 1). ). Such a lip coat cosmetic can suppress secondary adhesion, but cannot avoid feeling like a film after application, and sometimes the finish becomes matte and loses "gloss".
特許文献２には、所定粘度のメチルフェニルポリシロキサン、無水ケイ酸、及びポリメチルシルセスキオキサン粒子を、各々所定量配合した油性リップコートが、耐移り性、使用性、及び安定性に優れていると記載されている。しかしながら、特許文献２の油性リップコートにおいては、にじみを抑制するために採用したメチルフェニルポリシロキサンに安定に配合するための粉末はポリメチルシルセスキオキサンに限られている。
In Patent Document 2, an oil-based lip coat containing predetermined amounts of methylphenylpolysiloxane, silicic anhydride, and polymethylsilsesquioxane particles each having a predetermined viscosity is excellent in transfer resistance, usability, and stability. It is stated that However, in the oil-based lip coat of Patent Document 2, polymethylsilsesquioxane is the only powder that can be stably blended with methylphenylpolysiloxane used to suppress bleeding.

非揮発性ジメチコンは、口紅に汎用されている油分と相溶性がないため、下地に塗布した口紅を滲ませることなく口紅の上を被うため、優れた耐移り性を付与することができる。しかしながら、金属石鹸を配合しない比較例１－１は粘度が低すぎて塗布具から垂れ落ちてしまい塗布することができず、金属石鹸の配合量が５質量％を超える比較例１－２は粘度が高すぎて塗布具につかず、塗布具で容器からとることができなかった。
Non-volatile dimethicone is not compatible with the oil commonly used in lipstick, so it can be applied over the lipstick without bleeding the base lipstick, giving it excellent transfer resistance. However, Comparative Example 1-1 containing no metal soap had too low a viscosity and dripped from the applicator and could not be applied. was too high to stick to the applicator and could not be removed from the container with the applicator.
（ａ）非揮発性ジメチコンと（ｃ１）フェニル変性シリコーンとの油中油型乳化物とした実施例２－１～２－４は、耐移り性、使いやすさ、及び仕上がりの全てにおいて優れていた。しかしながら、フェニル変性シリコーンの配合量が６０質量％を超える比較例２－１は、安定な乳化物を調製することができなかった。

However, in Comparative Example 2-1, in which the amount of phenyl-modified silicone was more than 60% by mass, a stable emulsion could not be prepared.
（ａ）非揮発性ジメチコンを外相（連続相）、（ｃ２）水を内相（分散相）とする油中水型乳化物とした実施例３－１～３－７は、優れた耐移り性及び使いやすさを示した。但し、化粧料の粘度が１４Ｐａ・ｓを超えると、耐移り性及び使いやすさは優れているが、塗布後に白くなり、仕上がりが低下する場合があった（データは示さず）。
（ａ）非揮発性ジメチコンを内相（分散相）、（ｃ２）水を外相（連続相）とする水中油型乳化物とした実施例３－８は、油中水型と比較すると使いやすさ及び仕上がりが若干劣っていたが十分に満足できる特性を有していた。
一方、油中水型及び水中油型のいずれでも、金属石鹸を配合しない比較例３－１及び３－２は安定な乳化物を調製することができなかった。 Examples 3-1 to 3-7, which were water-in-oil emulsions in which (a) non-volatile dimethicone was the outer phase (continuous phase) and (c2) water was the inner phase (dispersed phase), had excellent transfer resistance. demonstrated its versatility and ease of use. However, when the viscosity of the cosmetic exceeds 14 Pa·s, although the transfer resistance and ease of use are excellent, the cosmetic may become white after application and the finish may deteriorate (data not shown).
(a) non-volatile dimethicone as an internal phase (dispersed phase), (c2) Example 3-8 as an oil-in-water emulsion with water as an external phase (continuous phase) is easier to use than the water-in-oil type Although the hardness and finish were slightly inferior, the properties were sufficiently satisfactory.
On the other hand, in Comparative Examples 3-1 and 3-2 containing no metal soap, stable emulsions could not be prepared in either the water-in-oil type or the oil-in-water type.
