Abstract
Description
本発明は、水中油型乳化組成物に関するものである。 The present invention relates to an oil-in-water emulsified composition.
水中油型乳化組成物は、肌に塗布した際に爽やかでしっとりした感触が得られることから、肌に直接適用される皮膚化粧料等の皮膚外用剤の基剤として広く用いられている。特に、水中油型乳化組成物には、塗布後の肌のべたつきやきしみの軽減、皮膚を柔軟化する効果があることから、シリコーンエラストマーが配合されている（例えば特許文献１や２）。 The oil-in-water emulsified composition is widely used as a base for external skin preparations such as skin cosmetics that are directly applied to the skin because it gives a refreshing and moist feel when applied to the skin. In particular, the oil-in-water emulsified composition contains a silicone elastomer because it has the effects of reducing stickiness and squeaking of the skin after application and softening the skin (for example, Patent Documents 1 and 2).
ところで、ジメチコジエチルベンザルマロネートは、ＵＶ－Ｂ領域（ultraviolet-B：２８０～３２０ｎｍ）の紫外線吸収剤の一種であるが、他の紫外線吸収剤に比べて、紫外線防御能力が低く、その配合量を多くして高いＳＰＦ（sun protection factor）製品を目指す場合には、高配合によるきしみや油っぽさといった問題を有している。このような問題に鑑み、特許文献３には、ジメチコジエチルベンザルマロネートと２，２’－メチレンビス［６－（２Ｈ－ベンゾトリアゾール－２－イル）－４－（１，１，３，３－テトラメチルブチル）フェノール］とを組み合わせて配合した日焼け止め化粧料に、特定構造の両末端シリコーン変性グリセリンを配合することで、高いＳＰＦを有する製品を製造する場合であっても、優れた使用感が得られることが記載されている。 By the way, dimethicodiethylbenzalmalonate is a kind of ultraviolet absorber in the UV-B region (ultraviolet-B: 280 to 320 nm), but its ultraviolet protection ability is lower than that of other ultraviolet absorbers, and its ultraviolet protection ability is low. When aiming for a high SPF (sun protection factor) product with a large amount of compounding, there are problems such as squeak and oiliness due to the high compounding amount. In view of such problems, Patent Document 3 describes dimethicodiethylbenzalmalonate and 2,2'-methylenebis [6- (2H-benzotriazole-2-yl) -4- (1,1,3). 3-Tetramethylbutyl) Phenol] is blended with sunscreen cosmetics, and by blending double-ended silicone-modified glycerin with a specific structure, it is excellent even when producing products with high SPF. It is described that a feeling of use can be obtained.
一般に、シリコーンエラストマーを配合すると吸光度が低下することが知られている。今般、シリコーンエラストマーの分散に特定の界面活性剤を用いたところ、吸光度が飛躍的に向上し、さらにその分散体にジメチコジエチルベンザルマロネートを配合してみたところ、吸光度が相乗的に向上することを見出し本発明に至った。 In general, it is known that the absorbance decreases when a silicone elastomer is blended. Recently, when a specific surfactant was used to disperse the silicone elastomer, the absorbance dramatically improved, and when dimethicodiethylbenzalmaronate was added to the dispersion, the absorbance synergistically improved. It was found that this was done, and the present invention was reached.
すわなち、本発明は上記知見に基づきなされたものであり、シリコーンエラストマーが配合されていても吸光度を向上させることが可能な水中油型乳化組成物を提供することを目的とするものである。 That is, the present invention has been made based on the above findings, and an object of the present invention is to provide an oil-in-water emulsified composition capable of improving the absorbance even if a silicone elastomer is blended. ..

In the following, POE is an abbreviation for polyoxyethylene, PEG is an abbreviation for polyethylene glycol, and PPG is an abbreviation for polypropylene glycol.
（Ａ）ジメチコジエチルベンザルマロネート
本発明の水中油型乳化組成物に含まれるジメチコジエチルベンザルマロネートは常温で液状のシリコーン変性化合物で、ポリシリコーン－１５とも呼ばれる。（Ａ）ジメチコジエチルベンザルマロネートは公知の紫外線吸収剤であり市販品を使用でき、例えば、「ＰＡＲＳＯＬ ＳＬＸ」（ＤＳＭ Ｎｕｔｒｉｔｉｏｎａｌ Ｐｒｏｄｕｃｔｓ）が挙げられる。（Ａ）ジメチコジエチルベンザルマロネートの配合によって、さらに吸光度が相乗的に向上する作用機序は必ずしも明らかではないが、後述する（Ｂ）シリコーンエラストマーが構成する分子の穴に（Ａ）ジメチコジエチルベンザルマロネートが入り込むことで、（Ｂ）シリコーンエラストマーによる吸光度の低下を抑制することができるものと考えられる。
(A) Dimethicodiethylbenzalmalonate Dimethicodiethylbenzalmaronate contained in the oil-in-water emulsified composition of the present invention is a silicone-modified compound liquid at room temperature and is also called polysilicone-15. (A) Dimethicodiethylbenzalmalonate is a known ultraviolet absorber and a commercially available product can be used. Examples thereof include "PARSOL SLX" (DSM Nutritional Products). Although the mechanism of action in which (A) dimethicodiethylbenzalmalonate further synergistically improves the absorbance is not always clear, (A) dimethi is formed in the hole of the molecule composed of (B) silicone elastomer, which will be described later. It is considered that the inclusion of codiethylbenzalmalonate can suppress the decrease in absorbance due to (B) the silicone elastomer.
（Ａ）ジメチコジエチルベンザルマロネートの配合量は、組成物全量に対して０．１～１０質量％であることが好ましく、より好ましくは０．３～８質量％、さらには０．５～５質量％であることが好ましい。組成物全量に対して０．１質量％以上であることで、吸光度をより向上させることができ、１０質量％以下であることでより良好な使用性を確保することができる。 The blending amount of (A) dimethicodiethylbenzalmalonate is preferably 0.1 to 10% by mass, more preferably 0.3 to 8% by mass, and further 0.5 by mass with respect to the total amount of the composition. It is preferably ~ 5% by mass. When it is 0.1% by mass or more with respect to the total amount of the composition, the absorbance can be further improved, and when it is 10% by mass or less, better usability can be ensured.
（Ｂ）シリコーンエラストマー
本発明の水中油型乳化組成物に含まれるシリコーンエラストマー（架橋型シリコーン）は、特に限定されるものではないが、ジメチコンクロスポリマー、ジメチコン／ビニルジメチコンクロスポリマー（ポリシリコーン１１）、ジメチコン／フェニルビニルジメチコンクロスポリマー、ビニルジメチコン／ラウリルジメチコンクロスポリマー、ラウリルポリジメチルシロキシエチルジメチコン／ビス－ビニルジメチコンクロスポリマー、アルキル（Ｃ３０－４５）セテアリルジメチコンクロスポリマー、セテアリルジメチコンクロスポリマーからなる群より選択される１種または２種以上が好ましく用いられる。
(B) Silicone Elastomer The silicone elastomer (crosslinked silicone) contained in the oil-in-water emulsifying composition of the present invention is not particularly limited, but is not particularly limited, but is a dimethicone crosspolymer, a dimethicone / vinyldimethicone crosspolymer (polysilicone 11). , Dimethicone / phenylvinyldimethicone crosspolymer, vinyldimethicone / lauryldimethicone crosspolymer, laurylpolydimethylsiloxyethyl dimethicone / bis-vinyldimethicone crosspolymer, alkyl (C30-45) cetearyl dimethicone crosspolymer, cetearyl dimethicone crosspolymer. One or more selected from the group is preferably used.
本発明の水中油型乳化組成物を調製するに際しては、シリコーンエラストマーを、常温で液状の油分で膨潤した膨潤物の形態で配合することが好ましい。これにより、架橋型シリコーンの分散性および安定性がさらに向上する。
膨潤に用いられる液状油分としては、例えば液状シリコーン油、液状炭化水素油、液状エステル油、液状高級脂肪酸などが挙げられ、特に、常温（２５℃）で低粘度、例えば、１００ｍＰａ・ｓ以下の液状油分が好ましい。好ましい粘度範囲は、１～１００ｍＰａ・ｓである。
好ましい配合形態であるシリコーンエラストマーの液状油膨潤物において、架橋型シリコーンと液状油の混合の比率は質量比で、５：９５～４０：６０が好適である。液状油膨潤物がこの質量比の範囲にあることで、水中油型乳化組成物の調製がより好適となる。
When preparing the oil-in-water emulsified composition of the present invention, it is preferable to blend the silicone elastomer in the form of a swelled product swollen with an oil that is liquid at room temperature. This further improves the dispersibility and stability of the crosslinked silicone.
Examples of the liquid oil content used for swelling include liquid silicone oil, liquid hydrocarbon oil, liquid ester oil, liquid higher fatty acid and the like, and in particular, low viscosity at room temperature (25 ° C.), for example, liquid of 100 mPa · s or less. Oil is preferred. The preferred viscosity range is 1 to 100 mPa · s.
In the liquid oil swelling product of the silicone elastomer, which is a preferable compounding form, the mixing ratio of the crosslinked silicone and the liquid oil is preferably 5:95 to 40:60 in terms of mass ratio. The fact that the liquid oil swelling material is within this mass ratio makes the preparation of an oil-in-water emulsified composition more suitable.

表１に示すように、実施例の水中油型乳化組成物はシリコーンエラストマーが配合されていても吸光度のピークトップ値、積算値ともに高かった。一方、（Ｃ）成分を含まない比較例１や（Ａ）ジメチコジエチルベンザルマロネートを含まない比較例２や３では吸光度のピークトップ値、積算値が優位に低下した。特に、比較例３はサンケア化粧品に有用であるとして最も使用されているオクトクリレンを増量しても実施例のピークトップ値、積算値には及ばなかった。 As shown in Table 1, the oil-in-water emulsified compositions of Examples had high peak top values and integrated values of absorbance even when the silicone elastomer was blended. On the other hand, in Comparative Example 1 containing no component (C) and Comparative Examples 2 and 3 not containing dimethicodiethylbenzalmalonate, the peak top value and the integrated value of the absorbance were significantly lowered. In particular, in Comparative Example 3, even if the amount of octocrylene, which is most used as being useful for sun care cosmetics, was increased, the peak top value and the integrated value of Examples were not reached.
