Abstract
本发明提供包装在具有分开的第一和第二储存区域的分配器中的一种化妆品。第一区域装有第一化妆品组合物,该组合物含有第一肤用活性剂,优选自溶角蛋白肤用剂。特别优选α-和β-羟基羧酸作为第一肤用活性物质,置于pH约1-约5.5的组合物中。第二区域装有第二化妆品组合物,该第二肤用剂与第一组合物不相容。特别优选第二肤用剂是维生素A类、维生素、酶和抗氧剂。最优选视黄醇。所述的分配器能够使第一和第二组合物以约30∶1-约2∶1的各自分配重量比通过喷嘴输送出来。
Description
本发明涉及具有二元组合物的化妆品,优选储藏在独立的室内,各个组合物含有皮肤活性物质同时至少一种活性物质与含有另一种活性物质的组合物不相容。
柔软、饱满和弹性皮肤具有醒目的美学吸引力。由于人体皮肤随着时间老化,表皮可能变得皱褶、突起或起皱纹。这些表明着年轻外观的失去并且预示向老年转变。暴露在大量日光下会加速这种转变过程。此外,被称作角质层的表皮外层会在暴露于严冷气候或过多与洗涤剂或溶剂接触之后变干和变薄。
科学研究发现数种可以抵抗衰老进程的物质。其中有维生素A类和α-羟基羧酸类化合物。不幸的是这些活性物质可能在某些条件下不相容。视黄醇在非常有利于α-羟基的酸性条件下迅速降解。这些活性物质的联合业已报导在美国专利5,935,589(Mukherjee等),其将活性物质置于单一组合物的独立乳液中。视黄醇在中性pH下在水包油乳液内稳定。α-羟基羧酸如羟乙酸分散在油包水乳液中。这两种乳液随后小心地混合形成一种化妆品组合物。此类组合物的问题在于随着时间推移,在分开的乳液之间会出现泄漏导致视黄醇降解。
一种更加直接的解决方法是将不同的活性物质置于存在于分配器的独立隔室内的组合物中。例如美国专利5,914,116(Suares等)公开了可释放可封闭堆叠式瓶和双室泵。这些包装设计成在不同时间运送分开的活性物质而不是通过同时施用。在美国专利5,137,178(Stokes等)中公开了一种双室可挤压化妆品分配器,其允许分开的组合物流能够同时挤出。
虽然上述各种体系具有其特定优点,但它们存在某些缺陷。置于双流分配室中的活性物质必须加倍浓缩。在最终的分配混合流浓缩物中各物流只占一半。例如,8%α-羟基羧酸的输送就需要从等分配双流包装中输送16%浓缩流出物。高浓度会出现问题。局部、未完全混合的流出物在皮肤上的沉积可能导致明显的皮肤刺激和红斑。高浓度下的内部稳定性也可能受损。因此需要更好的解决方法。
WO98/50012(Noordam等)讨论了使维生素C的低pH乳液稳定化以防止活性物质氧化的问题。通过将较浓的含水维生素C组合物置于多室分配系统的一个室中达到上述稳定化作用。第二室装有化妆品载体组合物。当备用时,将小体积的维生素C浓缩物与较大体积的载体基质一起分配,各自从独立室中挤出。
一种相似的方法业已由Airspray公开在其Symbio双室分配器的产品手册中。两种不相容组分分别彼此分开直至使用时为止。Symbio包装具有两个独立隔室,分别与其各自的泵相连,并且一个隔室较小且安排用来输送不稳定化妆物质的浓缩物。其中上述不稳定物质有维生素A(视黄醇)、维生素C(抗坏血酸)和维生素E(α-生育酚)。
然而,迄今不曾提出过用较大容器装盛除一些酶或色素沉着控制剂之外的皮肤活性物质。该技术没有提供从双室以提供储存浓度和皮肤输送浓度大致相等的方式输送活性物质的解决方案。焦点在于活性物质以高浓度储藏但输送其稀释物。
所以,本发明的优越性在于能够提供一种化妆品,其可以将第一肤用活性物质以基本上与其储存浓度没有区别的浓度输送到皮肤上,并且同时从分开的物流中输送出与第一活性物质不相容的第二肤用活性物质。
本发明的另一优越性是能够提供一种化妆品,其将酸性第一肤用活性物质以基本上与其储存浓度没有区别的浓度输送到皮肤上,同时输送pH与第一肤用活性物质不相容的第二肤用活性物质。
本发明的另一优越性是能够提供一种化妆品,其从分开的组合物以确保混合的协同皮肤有益效果的方式提供第一和第二活性物质的混合物。
本发明的再一方面是能够提供一种化妆品,其从分开的组合物以对皮肤相对无刺激的方式输送第一和第二活性物质的混合物。
本发明的这些和其他优越性将从下列概述和详述变得更加清楚。
所以,按照第一方面,提供一种化妆品,其含有:
(i)第一化妆品组合物,其中在药学可接受载体中含有约0.1-约
20重量%的第一肤用活性物质,该第一肤用活性物质会刺激皮
肤;
(ii)第二化妆品组合物,其含有占所述第二组合物重量约0.01-
约20重量%的与第一肤用组合物不相容且输送到药学可接受
载体中的第二肤用活性物质;和
(iii)一种分配器,具有将第一和第二化妆品组合物分开储存的第
一和第二区域,其中第一和第二组合物以约30∶1-约2∶1
的各自分配重量之比分配至出口喷嘴。
目前已经发现,第一肤用活性物质可以以与其储存浓度没有很大差异的浓度输送到皮肤上,同时与单独储存的和第一组合物不相容的第二肤用活性物质混合。在使用时将不等量的两种组合物从一个分配器中送出。第一与第二化妆品组合物的重量比可以是约30∶1-约2∶1,优选约15∶1-约8∶1,最佳是约11∶1。通过这种安排,第一肤用活性物质输送浓度小于其储存浓度不超过约10-20%。
本发明的组合物的输送可以通过双室分配器进行。特别有用的装置是由Airspray International Inc.以Symbio的商标出售。该包装具有具有两个分开的隔室,分别与其各自的泵相连。两个泵皆通过同一传动装置带动。通过推压该传动装置,保存在各隔室内的组合物被同时泵出并以受控比例混合。隔室之一是通过插管的方式与其各自的泵相连的传统容器。在该隔室有一个在底部带有活塞的药筒形式的更小室,其在使用时向前移动由此使该药筒及其内容物不含有空气。每个泵冲程输送约0.4g的产品。每个冲程中,第一外部容器和该药筒之间的产品输送比例是约1∶1。
泵体系不是唯一一种适用于本发明的分配器。输送可以通过可挤压塑料管实现,该管装有储存在独立区域内的两种不连续组合物,这两个区域以与彩条牙膏系统相似的方式一个堆叠在另一个上面。这种技术的示例是美国专利4,211,341(Weyn),在此引入作为参考。
第一肤用活性物质可以选自广泛的物质,尤其是溶角蛋白剂如α-和β-羟基羧酸类化合物。本发明特别适用于羟基羧酸类化合物,因为此类化合物具有高水平的刺激性并且需要与许多其他在低pH条件下容易分解的活性物质分开。所以,优选该第一组合物应保持在约1-约5.5,优选约2-约4.5的低pH环境中。
业已注意到,如果在过高浓度下使用,含低pHα-羟基羧酸的组合物存在严重的皮肤刺痛后果。当希望将10%浓度的α-羟基羧酸置于皮肤上时,从各隔室等体积输送的双室容器必须储存浓度为20%的α-羟基羧酸。在该水平下两倍强度的活性物质非常刺痛。本发明通过允许α-羟基羧酸在远低于两倍强度的水平下输送从而避免了该问题。
其中R和R1是H、F、Cl、Br、烷基、芳烷基或芳基,其为饱和或不饱和、同分异构或者非同分异构、直链或支链、具有1-25个碳原子或者具有5-6员环的环状形式,并且此外,R和R1可以带有OH、CHO、COOH和具有1-9个碳原子的烷氧基,当R和R1不相同时,该α-羟基羧酸作为游离酸、立体异构体、D、L和DL形式存在。

实施例9
进行临床研究来评估与从二元分配包装分配不等浓度的肤用活性物质相关的减轻刺痛感的有益效果。
制剂 产品A
将含8.7%羟基乙酸配方置于本发明实施例分配泵(Airspary)的外室中。内室装有不含羟基乙酸的基质配方。该包装的分配比例能够使分配出11份外部配方的同时分配出1份内部配方。因此共同分配的产品中与皮肤接触的羟基乙酸的最终浓度是8%。产品B(对比)
将16%羟基乙酸配制在与产品A所述的相同基质配方中并且置于市售的分配比例为1∶1的双室泵的一个室内。另一室装有与产品A的内室相同的配方。因此当共同分配时与皮肤接触的羟基乙酸的最终浓度是8%。试验设计:
基于其对α羟基酸产品所致的刺痛或灼伤感的感觉能力及其区别含16%羟基乙酸和含8%羟基乙酸的能力来预选出6名对象。在接近鼻孔和位于唇上方的区域内首先粘贴上D-鳞带以除去污物和油。各将约3mg的产品A和B分配在各对象的左和右食指上。对象不了解任何有关这些产品的情况,询问他们有关在粘净区域上同时涂覆两种产品的感觉。询问他们可以评估在涂覆一分钟内与另一侧相比是否感觉到更加大的灼伤或刺痛感。结果:
对象1 | B>A |
对象2 | B>A |
对象3 | B>A |
对象4 | B=A |
对象5 | B>A |
对象6 | B>A |
6名对象中5人立刻感觉到产品B的刺痛感更大。该结果证实以本发明的不等分配比例输送羟基乙酸能够产生减轻皮肤突然暴露在1∶1分配包装输送的高浓度的羟基乙酸时所引起的即时不适刺痛感的效益。
上述说明和实施例举例说明本发明所选的实施方式。根据这些所属领域技术人员能够提出不同和改进的方案,这些都属于本发明的实质和权限内。
