- an oil-in-water emulsified composition containing a platinum catalyst which is excellent in storage stability of the platinum catalyst at high temperatures.
- the oil-in-water emulsifying composition of the present disclosure is an oil-in-water emulsifying composition containing a dispersion medium containing water and oil droplets dispersed in the dispersion medium, wherein the oil droplets are an oil component, an emulsifier, and the like.
- a catalyst the oil content contains the first unsaturated organopolysiloxane, the catalyst contains a platinum complex coordinated with 1,3-divinyltetramethyldisiloxane, and the first relative to the total amount of platinum in the platinum complex.
- the mass ratio of the unsaturated organopolysiloxane of 1 is 200 or more.
- the oil-in-water emulsified composition of the present disclosure has excellent storage stability of the platinum catalyst at high temperatures, and blackening, reduction of catalytic activity, etc. due to aggregation of the platinum catalyst, etc.
- the principle of action that can reduce or prevent defects is considered to be as follows.
- the platinum catalyst of the present disclosure is intended to be a platinum complex represented by the following formula 1 in which 1,3-divinyltetramethyldisiloxane is coordinated with respect to platinum:
- 1,3-divinyltetramethyldisiloxane is coordinated with respect to platinum, which causes steric hindrance and suppresses aggregation of the platinum catalyst as compared with platinum having no ligand. can do.
- a platinum catalyst having such a ligand is mixed with a high-viscosity silicone oil, for example, if it is not stored in a cool and dark place with nitrogen purge, the platinum catalyst will aggregate and turn black. Resulting in. Aggregation of the platinum catalyst leads to an increase in the particle size of the platinum catalyst, that is, a decrease in the surface area, which may cause a decrease in the catalytic activity.
- 1,3-divinyltetramethyldisiloxane which is a ligand, becomes easy to be attached to and detached from platinum because its thermal motion becomes active as the temperature rises.
- the surface of platinum tends to be temporarily exposed, and when it comes into contact with adjacent platinum, it tends to aggregate, so it is considered that blackening progresses especially at high temperatures.
- the present inventor has added a predetermined amount of a platinum catalyst to the first unsaturated organopoly, even in the case of an oil-in-water emulsified composition which is a water-containing system, which is generally said to have worse storage stability. Surprisingly, it was found that the storage stability of the platinum catalyst at high temperatures was improved when it was added to the oil phase together with siloxane.
- the first unsaturated organopolysiloxane which is simultaneously blended in the oil phase, also has the ability to coordinate with platinum. Therefore, even if 1,3-divinyltetramethyldisiloxane deviates from platinum as the temperature rises, the first unsaturated organopolysiloxane complements the site and suppresses the progress of aggregation of the platinum catalyst. It is thought that it can be done.
- the fact that the oil phase is dispersed in the form of fine emulsified particles (oil droplets) is considered to be one of the factors that suppress the progress of aggregation of the platinum catalyst. ing. That is, even if the complementary action of the first unsaturated organopolysiloxane occurs, the newly coordinated first unsaturated organopolysiloxane is also detached from the platinum catalyst by thermal motion, so that the surface of platinum is exposed. Can be. In the case of a single phase containing only an oil phase, since the oil phase in which the platinum catalyst is present is a continuous phase, it is considered that there is a relatively high possibility that platinum having a bare surface comes into contact with each other.
- the oil phase is dispersed in the form of emulsified particles, and is separated from the platinum catalyst in other emulsified particles via the aqueous phase.
- the possibility of platinum having bare surfaces coming into contact with each other is lower than in the case of a single phase containing only an oil phase.
- the complementary action of the predetermined amount of the first unsaturated organopolysiloxane blended in the oil phase and the separating action of the platinum catalyst by the emulsified particles are synergistic. Therefore, it is thought that the storage stability of the platinum catalyst at high temperatures can be improved. Needless to say, if the storage stability at a high temperature is excellent, the storage stability at a low temperature is more excellent than that.
- high temperature can be intended to be 50 ° C. or higher, 60 ° C. or higher, or 70 ° C. or higher, and 90 ° C. or lower, 85 ° C. or lower, or 80 ° C. or lower.

Description
本開示は、白金触媒を含む水中油型乳化組成物、及びその使用方法に関する。
The present disclosure relates to an oil-in-water emulsified composition containing a platinum catalyst and a method for using the same.
従来より、白金触媒は、ポリマー重合などの種々の用途で使用されている。
Conventionally, platinum catalysts have been used in various applications such as polymer polymerization.
特許文献1には、皮膚に塗布するための配合物であって、a)(i)25℃にて100,000~500,000cst又はcPの粘度を有する高粘度のビニル末端化されたオルガノポリシロキサンの少なくとも1種、25℃にて500~50,000cst又はcPの粘度を有する低粘度のビニル末端化されたオルガノポリシロキサンの少なくとも1種、及び少なくとも1種のヒドリド官能化ポリシロキサンを含む反応性要素;並びに(ii)補強要素を含む反応性補強成分;及びb)白金触媒を含む架橋成分;を含み、架橋成分は、in situで反応性補強成分の架橋を促進し、その結果、皮膜が皮膚に形成される、配合物が開示されている。
Patent Document 1 describes a formulation for application to the skin, a) (i) a highly viscous vinyl-terminated organopoly having a viscosity of 100,000-500,000 cst or cP at 25 ° C. Reactions comprising at least one siloxane, at least one low-viscosity vinyl-terminated organopolysiloxane having a viscosity of 500-50,000 cst or cP at 25 ° C., and at least one hydride-functionalized polysiloxane. It contains a sex element; and (ii) a reactive reinforcing component containing a reinforcing element; and b) a cross-linking component containing a platinum catalyst; the cross-linking component promotes cross-linking of the reactive reinforcing component in situ, resulting in a film. Disclosed are formulations that form on the skin.
白金触媒は、典型的には、保存安定性に劣る不安定な触媒であるため、一般的には、オイル中に分散させ、かつ、窒素パージした状態で冷暗所において保管されている。
Since the platinum catalyst is typically an unstable catalyst with poor storage stability, it is generally stored in a cool and dark place in a state of being dispersed in oil and purged with nitrogen.
白金触媒の使用形態のバリエーションを増やすには、例えば、白金触媒及び油相に加えて、水相を併用することが考えられる。しかしながら、白金触媒は水分に敏感であり、白金触媒を、水を含む系で安定化させることは困難であった。ましてや、水を含む系において、高温環境下での保存安定性を向上させることはより一層困難であった。
In order to increase the variation of the usage pattern of the platinum catalyst, for example, it is conceivable to use an aqueous phase in combination with the platinum catalyst and the oil phase. However, the platinum catalyst is sensitive to water, and it has been difficult to stabilize the platinum catalyst in a system containing water. Furthermore, in a system containing water, it was even more difficult to improve the storage stability in a high temperature environment.
したがって、本開示の主題は、高温下での白金触媒の保存安定性に優れる、白金触媒を含む水中油型乳化組成物を提供することである。
Therefore, the subject of the present disclosure is to provide an oil-in-water emulsified composition containing a platinum catalyst, which is excellent in storage stability of the platinum catalyst at high temperatures.

本開示によれば、高温下での白金触媒の保存安定性に優れる、白金触媒を含む水中油型乳化組成物を提供することができる。
According to the present disclosure, it is possible to provide an oil-in-water emulsified composition containing a platinum catalyst, which is excellent in storage stability of the platinum catalyst at high temperatures.
以下、本開示の実施の形態について詳述する。本開示は、以下の実施の形態に限定されるものではなく、発明の本旨の範囲内で種々変形して実施できる。
Hereinafter, embodiments of the present disclosure will be described in detail. The present disclosure is not limited to the following embodiments, and can be variously modified and implemented within the scope of the spirit of the invention.
本開示の水中油型乳化組成物は、水を含む分散媒、及びこの分散媒中に分散している油滴を含む、水中油型乳化組成物であって、油滴は、油分、乳化剤、及び触媒を含み、油分が、第1の不飽和オルガノポリシロキサンを含み、触媒が、1,3-ジビニルテトラメチルジシロキサンが配位した白金錯体を含み、かつ、白金錯体における白金の全量に対する第1の不飽和オルガノポリシロキサンの質量比が、200以上である。
The oil-in-water emulsifying composition of the present disclosure is an oil-in-water emulsifying composition containing a dispersion medium containing water and oil droplets dispersed in the dispersion medium, wherein the oil droplets are an oil component, an emulsifier, and the like. And a catalyst, the oil content contains the first unsaturated organopolysiloxane, the catalyst contains a platinum complex coordinated with 1,3-divinyltetramethyldisiloxane, and the first relative to the total amount of platinum in the platinum complex. The mass ratio of the unsaturated organopolysiloxane of 1 is 200 or more.
原理によって限定されるものではないが、本開示の水中油型乳化組成物が、高温下での白金触媒の保存安定性に優れ、白金触媒の凝集に伴う、黒化、触媒活性の低下等の不具合を低減又は防止し得る作用原理は以下のとおりであると考える。
Although not limited by the principle, the oil-in-water emulsified composition of the present disclosure has excellent storage stability of the platinum catalyst at high temperatures, and blackening, reduction of catalytic activity, etc. due to aggregation of the platinum catalyst, etc. The principle of action that can reduce or prevent defects is considered to be as follows.
本開示の白金触媒とは、1,3-ジビニルテトラメチルジシロキサンが白金に対して配位した、下記式1で示される白金錯体を意図する:
The platinum catalyst of the present disclosure is intended to be a platinum complex represented by the following formula 1 in which 1,3-divinyltetramethyldisiloxane is coordinated with respect to platinum:
かかる白金触媒は、白金に対して1,3-ジビニルテトラメチルジシロキサンが配位しているため、それが立体障害となり、配位子を有さない白金に比べれば、白金触媒の凝集を抑制することができる。しかしながら、このような配位子を有する白金触媒を、例えば、高粘度のシリコーン油に配合したとしても、窒素パージをした状態で冷暗所において保管しなければ、白金触媒の凝集は進行し、黒く変色してしまう。白金触媒の凝集は、白金触媒の粒子径の増大、すなわち、表面積の低下につながるため、触媒活性の低下を生じさせる原因にもなり得る。
In such a platinum catalyst, 1,3-divinyltetramethyldisiloxane is coordinated with respect to platinum, which causes steric hindrance and suppresses aggregation of the platinum catalyst as compared with platinum having no ligand. can do. However, even if a platinum catalyst having such a ligand is mixed with a high-viscosity silicone oil, for example, if it is not stored in a cool and dark place with nitrogen purge, the platinum catalyst will aggregate and turn black. Resulting in. Aggregation of the platinum catalyst leads to an increase in the particle size of the platinum catalyst, that is, a decrease in the surface area, which may cause a decrease in the catalytic activity.
配位子である1,3-ジビニルテトラメチルジシロキサンは、温度の上昇に伴い、その熱運動が活発になるため、白金から着脱しやすくなると考えられる。その結果、白金の表面は一時的にむき出し状態になりやすく、隣接する白金と接触したときに凝集しやすくなるため、特に高温下では黒化が進行すると考えられる。
It is considered that 1,3-divinyltetramethyldisiloxane, which is a ligand, becomes easy to be attached to and detached from platinum because its thermal motion becomes active as the temperature rises. As a result, the surface of platinum tends to be temporarily exposed, and when it comes into contact with adjacent platinum, it tends to aggregate, so it is considered that blackening progresses especially at high temperatures.
本発明者は、保存安定性が一般的により悪くなるといわれている、水を含む系である水中油型乳化組成物の場合であっても、白金触媒を所定量の第1の不飽和オルガノポリシロキサンとともに油相中に配合すると、意外にも、高温下での白金触媒の保存安定性が向上することを見出した。
The present inventor has added a predetermined amount of a platinum catalyst to the first unsaturated organopoly, even in the case of an oil-in-water emulsified composition which is a water-containing system, which is generally said to have worse storage stability. Surprisingly, it was found that the storage stability of the platinum catalyst at high temperatures was improved when it was added to the oil phase together with siloxane.
油相中に同時に配合する第1の不飽和オルガノポリシロキサンも、白金に対して配位する性能を有している。したがって、温度上昇に伴って、1,3-ジビニルテトラメチルジシロキサンが白金から外れたとしても、第1の不飽和オルガノポリシロキサンがその部位を補完するため、白金触媒の凝集の進行を抑制することができると考えられる。
The first unsaturated organopolysiloxane, which is simultaneously blended in the oil phase, also has the ability to coordinate with platinum. Therefore, even if 1,3-divinyltetramethyldisiloxane deviates from platinum as the temperature rises, the first unsaturated organopolysiloxane complements the site and suppresses the progress of aggregation of the platinum catalyst. It is thought that it can be done.
加えて、水中油型乳化組成物は、油相が、微小な乳化粒子(油滴)の形態で分散していることも、白金触媒の凝集の進行を抑制する要因の一つであると考えている。つまり、第1の不飽和オルガノポリシロキサンによる補完作用が生じたとしても、新たに配位した第1の不飽和オルガノポリシロキサンも熱運動によって白金触媒から着脱するため、白金の表面がむき出し状態になり得る。油相のみの単一相の場合、白金触媒が存在する油相は連続相であるため、表面がむき出し状態の白金同士が接触する可能性は比較的に高いと考えられる。一方、水中油型乳化組成物の場合は、油相が乳化粒子の形態で分散し、他の乳化粒子中の白金触媒とは水相を介して隔離されたような状態を呈している。その結果、油相のみの単一相の場合に比べて、表面がむき出し状態の白金同士が接触する可能性は低くなると考えられる。
In addition, in the oil-in-water emulsified composition, the fact that the oil phase is dispersed in the form of fine emulsified particles (oil droplets) is considered to be one of the factors that suppress the progress of aggregation of the platinum catalyst. ing. That is, even if the complementary action of the first unsaturated organopolysiloxane occurs, the newly coordinated first unsaturated organopolysiloxane is also detached from the platinum catalyst by thermal motion, so that the surface of platinum is exposed. Can be. In the case of a single phase containing only an oil phase, since the oil phase in which the platinum catalyst is present is a continuous phase, it is considered that there is a relatively high possibility that platinum having a bare surface comes into contact with each other. On the other hand, in the case of the oil-in-water emulsified composition, the oil phase is dispersed in the form of emulsified particles, and is separated from the platinum catalyst in other emulsified particles via the aqueous phase. As a result, it is considered that the possibility of platinum having bare surfaces coming into contact with each other is lower than in the case of a single phase containing only an oil phase.
したがって、本開示の水中油型乳化組成物によれば、油相中に配合する所定量の第1の不飽和オルガノポリシロキサンによる補完作用と、乳化粒子による白金触媒の隔離作用とが、相乗的に作用するため、白金触媒の高温下での保存安定性が向上し得ると考えている。なお、高温下での保存安定性が優れていれば、それよりも低温での保存安定性がより優れることは言うまでもない。
Therefore, according to the oil-in-water emulsified composition of the present disclosure, the complementary action of the predetermined amount of the first unsaturated organopolysiloxane blended in the oil phase and the separating action of the platinum catalyst by the emulsified particles are synergistic. Therefore, it is thought that the storage stability of the platinum catalyst at high temperatures can be improved. Needless to say, if the storage stability at a high temperature is excellent, the storage stability at a low temperature is more excellent than that.

乳化剤のなかでも、白金触媒の保存安定性等の観点から、高分子乳化剤が好ましい。高分子乳化剤は、一般的な乳化剤(界面活性剤)に比べ、典型的には、分子量が大きく、乳化能力の低い乳化剤(界面活性剤)を意図することができる。乳化安定性の向上を図る場合、一般的には、乳化能力の高い乳化剤が使用される。本発明者は、特定の白金触媒を含む乳化組成物の場合には、意外にも、乳化能力の比較的低い高分子乳化剤を使用した方が、白金触媒の保存安定性等がより一層優れることを見出した。原理は定かではないが、高分子乳化剤の使用による、白金触媒の保存安定性のより一層の向上効果は、次のように考えている。
Among the emulsifiers, polymer emulsifiers are preferable from the viewpoint of storage stability of the platinum catalyst. The polymer emulsifier can typically be intended as an emulsifier (surfactant) having a large molecular weight and a low emulsifying ability as compared with a general emulsifier (surfactant). When improving the emulsification stability, an emulsifier having a high emulsifying ability is generally used. Surprisingly, in the case of an emulsified composition containing a specific platinum catalyst, the present inventor finds that the use of a polymer emulsifier having a relatively low emulsifying ability is even more excellent in the storage stability of the platinum catalyst. I found. Although the principle is not clear, the effect of further improving the storage stability of the platinum catalyst by using the polymer emulsifier is considered as follows.
高分子乳化剤以外の一般的な乳化能力の高い乳化剤(界面活性剤)を使用すると、乳化粒子が細かくなるため、通常であれば、乳化組成物は安定化する。しかしながら、本開示で使用する白金触媒は、1,3-ジビニルテトラメチルジシロキサンが、触媒の表面に配位している。その結果、乳化能力の高い乳化剤が、かかる白金触媒を油相から水相へ引き抜くように作用するため、水相側へ移動した白金触媒は、不安定となって凝集が進み、黒化しやすくなると考えている。一方、乳化能力の低い高分子乳化剤は、このような白金触媒の水相への引き抜き作用が弱いため、白金触媒を油相中で安定的に保存し得ると考えている。
If a general emulsifier (surfactant) having a high emulsifying ability other than a polymer emulsifier is used, the emulsified particles become finer, so that the emulsified composition is usually stabilized. However, in the platinum catalyst used in the present disclosure, 1,3-divinyltetramethyldisiloxane is coordinated on the surface of the catalyst. As a result, the emulsifier having a high emulsifying ability acts to pull out the platinum catalyst from the oil phase to the aqueous phase, so that the platinum catalyst moved to the aqueous phase side becomes unstable, aggregates, and becomes easy to blacken. thinking. On the other hand, it is considered that the polymer emulsifier having a low emulsifying ability can stably store the platinum catalyst in the oil phase because the pulling action of the platinum catalyst into the aqueous phase is weak.
高分子乳化剤の重量平均分子量は、乳化安定性、白金触媒の保存安定性等の観点から、500以上、700以上、1,000以上、1,500以上、又は2,000以上とすることができる。高分子乳化剤の重量平均分子量の上限値については特に制限はなく、例えば、1,000,000以下、100,000以下、10,000以下、又は5,000以下とすることができる。なお、乳化剤の重量平均分子量は、乳化剤をN,N-ジメチルホルムアミド(DMF)に溶解させて0.5%溶液を作製し、これを用いて以下の条件でGPC(ゲルパーミエーションクロマトグラフィー)により測定して求めたポリスチレン換算値である:

〈結果〉
表1の比較例1~3の結果から分かるように、白金の全量に対する第1の不飽和オルガノポリシロキサンの質量比が200未満の場合には、いずれの条件下でも、組成物は黒色に変色してしまい、保存安定性に劣ることが確認できた。一方、白金の全量に対する第1の不飽和オルガノポリシロキサンの質量比が200以上である、実施例1~12の組成物は、少なくとも70℃で8時間の条件下においてA~D評価の結果が得られており、比較例1~3の組成物に比べて、保存安定性に優れることが確認できた。 <result>
As can be seen from the results of Comparative Examples 1 to 3 in Table 1, when the mass ratio of the first unsaturated organopolysiloxane to the total amount of platinum is less than 200, the composition turns black under any condition. It was confirmed that the storage stability was inferior. On the other hand, the compositions of Examples 1 to 12, in which the mass ratio of the first unsaturated organopolysiloxane to the total amount of platinum is 200 or more, are evaluated as A to D under the conditions of at least 70 ° C. for 8 hours. It was obtained, and it was confirmed that the composition was superior in storage stability as compared with the compositions of Comparative Examples 1 to 3.

On the other hand, the compositions of Examples 1 to 12, in which the mass ratio of the first unsaturated organopolysiloxane to the total amount of platinum is 200 or more, are evaluated as A to D under the conditions of at least 70 ° C. for 8 hours. It was obtained, and it was confirmed that the composition was superior in storage stability as compared with the compositions of Comparative Examples 1 to 3.
実施例1と実施例2とを比較した場合、実施例2の組成物の方が、保存安定性に優れていた。これは、エモリエント剤の配合に伴い、組成物の粘度が増加したためであると考えられる。すなわち、組成物の粘度を上昇させ得る他の剤、例えば増粘剤も同様の効果を奏し得ると考える。
When Example 1 and Example 2 were compared, the composition of Example 2 was superior in storage stability. It is considered that this is because the viscosity of the composition increased with the addition of the emollient agent. That is, it is considered that other agents capable of increasing the viscosity of the composition, for example, thickeners, can exert the same effect.
実施例1と実施例4とを比較した場合、実施例1の組成物の方が、保存安定性に優れていた。この結果から、シリコーン系乳化剤を配合する場合には、シリコーン系乳化剤は水相パーツではなく、油相パーツ中に配合した方が好ましいことが分かった。
When Example 1 and Example 4 were compared, the composition of Example 1 was superior in storage stability. From this result, it was found that when the silicone emulsifier is blended, it is preferable to blend the silicone emulsifier in the oil phase part instead of the aqueous phase part.
実施例1と実施例3とを比較した場合、実施例3の組成物の方が、保存安定性に優れていた。この結果から、白金触媒を含む乳化組成物においては、高分子乳化剤よりも乳化能力の高い乳化剤(例えばシリコーン系乳化剤)は、1質量%未満の量で配合するか、或いは、配合しないことが好ましいことが分かった。
When Example 1 and Example 3 were compared, the composition of Example 3 was superior in storage stability. From this result, in the emulsification composition containing a platinum catalyst, it is preferable to add an emulsifier having an emulsifying ability higher than that of the polymer emulsifier (for example, a silicone-based emulsifier) in an amount of less than 1% by mass, or not to add it. It turned out.
実施例3、6、7を比較すると分かるように、第1の不飽和オルガノポリシロキサンの粘度が低くなると、組成物の保存安定性が向上することが分かった。
As can be seen by comparing Examples 3, 6 and 7, it was found that when the viscosity of the first unsaturated organopolysiloxane is lowered, the storage stability of the composition is improved.
実施例1と実施例8を比較した場合、実施例8の組成物の方が、保存安定性に優れていた。この結果から、白金の全量に対する第1の不飽和オルガノポリシロキサンの質量比を増加させると、保存安定性がより向上することが分かった。また、高分子乳化剤よりも乳化能力の高い乳化剤(例えばシリコーン系乳化剤)を1質量%以上配合する場合には、白金の全量に対する第1の不飽和オルガノポリシロキサンの質量比を増加させることによって、保存安定性を向上させ得ることも分かった。
When Example 1 and Example 8 were compared, the composition of Example 8 was superior in storage stability. From this result, it was found that increasing the mass ratio of the first unsaturated organopolysiloxane to the total amount of platinum further improved the storage stability. Further, when an emulsifier having an emulsifying ability higher than that of a polymer emulsifier (for example, a silicone-based emulsifier) is blended in an amount of 1% by mass or more, the mass ratio of the first unsaturated organopolysiloxane to the total amount of platinum is increased. It was also found that the storage stability could be improved.

An artificial skin forming agent was obtained using the obtained first agent and the composition of Example 3 described above as the second agent.
第1剤を皮膚に適用して未架橋状態の第1剤層を形成し、その上から第2剤を第1剤層に対してかき混ぜるように適用したところ、変色及び架橋不良などの不具合が生じていない良好な人工皮膚が形成されることが確認できた。
When the first agent was applied to the skin to form an uncrosslinked first agent layer, and then the second agent was applied to the first agent layer by stirring, problems such as discoloration and poor crosslinking occurred. It was confirmed that good artificial skin that did not occur was formed.
