Description

本発明は、脂肪酸または脂肪酸石鹸、カチオンポリマー、水を配合する水系固形化粧料に関するものであり、塗布時に肌にみずみずしい感触を与え、化粧料の伸び広がりが良好で、化粧持続性が良好であり、しかも経時安定性に優れた水系固形化粧料に関するものである。   The present invention relates to a water-based solid cosmetic containing a fatty acid or fatty acid soap, a cationic polymer, and water, giving a fresh feel to the skin at the time of application, good spread of the cosmetic, and good makeup sustainability. In addition, the present invention relates to a water-based solid cosmetic having excellent stability over time.

従来より、固形化粧料は、携帯性や使用簡便性からファンデーション、白粉、チークカラー、アイシャドウ等のメーキャップ化粧料に汎用されている剤型である。このような固形化粧料には、粉体と油分を混合して圧縮成形した粉末固形タイプ、ワックス等で油を固めて成形した油性固形タイプ、ワックス等で油を固め、水分を内相に含んだW/O固形タイプ、外相の水分を固化剤により固めた水系固形タイプなどがある。   Conventionally, solid cosmetics are dosage forms that have been widely used in makeup cosmetics such as foundations, white powders, teak colors, and eye shadows because of their portability and ease of use. Such solid cosmetics include a powder solid type that is compression-molded by mixing powder and oil, an oily solid type that is formed by solidifying oil with wax, etc., oil is solidified with wax, etc., and moisture is contained in the inner phase. There is a W / O solid type, an aqueous solid type in which the moisture in the outer phase is solidified by a solidifying agent.

水系固形化粧料とは、外相の水分に、固化剤として脂肪酸石鹸、粘土鉱物、水溶性高分子等を添加し、油剤や粉末を分散させ、加熱溶融充填等により固形に成形した化粧料のことである。主成分が水であるため、使用時にそのゲル構造が破壊されると非常にみずみずしさを感じやすく、さっぱりとした使用感が得られる。   Water-based solid cosmetics are cosmetics that are added to the water in the outer phase by adding fatty acid soaps, clay minerals, water-soluble polymers, etc. as solidifying agents, dispersing oils and powders, and molding them into solids by hot melt filling. It is. Since the main component is water, when the gel structure is destroyed at the time of use, it is very easy to feel fresh and a refreshing feeling is obtained.

しかしながら、水系固形化粧料はみずみずしさを肌に多く与えようとすると固形の構造が弱くなりやすく、長期保存時に離水等の経時安定性不良が起きやすくなってしまう。また、逆に経時安定性を良好にしようとすると、固化剤の配合量が多くなり、みずみずしさをほとんど得られないものになるという問題点がある。 However, water-based solid cosmetics tend to weaken the solid structure when trying to impart a lot of freshness to the skin, resulting in poor stability over time such as water separation during long-term storage. On the other hand, if it is attempted to improve the stability over time, the amount of the solidifying agent increases, and there is a problem that almost no freshness can be obtained.

上記の問題点を解決する試みとして、脂肪酸石鹸と水溶性高分子自体のゲルの硬さを利用して水を固めた水系固形化粧料がある。例えば、特許文献1では、必須成分としてカラギーナン、ジェランガム、及び水膨潤性粘土鉱物を配合する水系固形化粧料が提案されている。この水系固形化粧料は、塗布時のみずみずしさ、化粧料の肌移りが良好で、使用時のよれを生じないため、使用時の使用性の観点では優れている。しかしながら、特許文献1に開示された技術では、化粧料において求められる長時間の化粧持続性に問題があった。   As an attempt to solve the above problems, there is an aqueous solid cosmetic in which water is hardened by utilizing the gel hardness of a fatty acid soap and a water-soluble polymer itself. For example, Patent Document 1 proposes an aqueous solid cosmetic containing carrageenan, gellan gum, and water-swellable clay mineral as essential components. This water-based solid cosmetic is excellent in terms of usability at the time of use because it is fresh at the time of application and the skin transfer of the cosmetic is good and does not cause a kinking at the time of use. However, the technique disclosed in Patent Document 1 has a problem in long-lasting makeup durability required for cosmetics.

また、異なる試みとして、特許文献2では、特定の脂肪酸石鹸量、油分、粉末を必須成分とし、脂肪酸石鹸の硬さを利用して水を固めた固形化粧料が提案されている。この技術によれば、みずみずしさを有し、携帯性に優れた水系固形状のメイクアップ化粧料が得られる。しかしながら、脂肪酸石鹸による硬さのコントロールが難しく、経時的に硬さが変化しやすいので経時安定性に問題があった。   Also, as a different trial, Patent Document 2 proposes a solid cosmetic material in which a specific amount of fatty acid soap, oil, and powder are essential components, and water is hardened using the hardness of the fatty acid soap. According to this technique, a water-based solid makeup cosmetic having freshness and excellent portability can be obtained. However, it is difficult to control the hardness with the fatty acid soap, and the hardness is likely to change over time, so that there is a problem in stability over time.

表1及び表2の結果から明らかなように、実施例1〜10は「塗布時のみずみずしさ」、「肌への伸び広がり」、「肌への伸び広がり」、「化粧膜の均一性」、「化粧持続性」、「経時安定性」の全ての項目に優れた水系固形化粧料であった。これに対して、表3から成分(a)の脂肪酸または脂肪酸石鹸がない比較例1は固形とはならず経時安定性に問題があり、成分(b)カチオンポリマーがない比較例2及び比較例3は、肌への均一な伸び広がり及び化粧持続性に問題があった。また、成分(b)の代わりに他の水溶性高分子を用いた比較例4及び5は、肌への伸び広がり、化粧膜の均一性、化粧持続性、経時安定性に問題があった。 As is clear from the results of Tables 1 and 2, Examples 1 to 10 are “freshness at the time of application”, “extension and spread to the skin”, “extension and spread to the skin”, and “uniformity of the cosmetic film”. It was a water-based solid cosmetic excellent in all items of “makeup durability” and “time stability”. On the other hand, Comparative Example 1 without the fatty acid or fatty acid soap of component (a) from Table 3 is not solid and has a problem in stability over time, and Comparative Example 2 and Comparative Example without component (b) cationic polymer No. 3 had a problem in uniform spread and spread on the skin and makeup sustainability. Further, Comparative Examples 4 and 5 using other water-soluble polymers instead of the component (b) had problems in spreading to the skin, uniformity of the makeup film, makeup persistence, and stability over time.
