本发明涉及一种具有核/壳结构的胶囊,其包含含有至少一种微水溶性或水不溶性有机活性成分的核,涉及一种制备该类具有核/壳结构的胶囊的方法、具有核/壳结构的胶囊的用途以及包含具有核/壳结构的胶囊的制剂。
Description
本发明涉及一种具有核/壳结构的胶囊,其包含含有至少一种微水溶性或水不溶性有机活性成分的核,涉及一种制备该类具有核/壳结构的胶囊的方法、具有核/壳结构的胶囊的用途以及包含具有核/壳结构的胶囊的制剂。
因各种原因进行活性成分的包封。例如,通过包封可以提高对光、氧气或水分敏感的那些活性成分的储存稳定性。在药物活性成分的情况下,活性成分释放可能通过包封而以目标方式影响。或者可以在包封之后以可倾注粉末处理液体物质。在包封人类皮肤的阳光保护领域用有机UV滤光剂的情况下,通过包封确保降低或甚至防止人类皮肤和该有机UV滤光剂之间的接触。
用金属氧化物层包封有机活性成分或将有机活性成分吸附在多孔金属氧化物中是已知的。
WO2005/009604A1描述了具有高活性成分含量的微胶囊,其中包含活性成分的核被壳包围,其中该壳包含无机聚合物。
WO2007/093252A1描述了包含至少一种氨基取代羟基二苯甲酮的UV滤光剂胶囊。
WO2009/012871A2描述了包含聚合物涂层、至少一种微溶性有机UV滤光剂和作为该微溶性有机UV滤光剂的溶剂的软化剂(emollient)的UV滤光剂胶囊。
尽管开头所述的现有技术,仍然需要对于该壳的非故意破坏显示出改进的稳定性或者具有更致密、更少孔的壳以防止活性成分逸出的胶囊。此外,可以用于化妆品领域中的胶囊应尽可能不释放皮肤刺激性成分如表面活性剂。最后,该生产胶囊的方法应尽可能宽范围有用且易于进行。该生产胶囊的方法应既对热应力稳定且还对机械应力稳定。
因此,本发明的目的是提供一种具有改进稳定性的含活性成分的胶囊或者提供一种具有降低的皮肤刺激潜力的含活性成分的胶囊并且能够通过简单且稳健的方法生产该新型含活性成分的胶囊。
该目的由具有核/壳结构的胶囊实现,该胶囊包含含有至少一种微水溶性或水不溶性有机活性成分的核和直接包围该核的壳,其中该壳包含金属氧化物或半金属氧化物的纳米颗粒且这些纳米颗粒通过至少一种另外的金属氧化物或半金属氧化物结合在一起,其中结合该纳米颗粒的所述另外的金属氧化物或半金属氧化物已经通过水不溶性或微水溶性溶胶-凝胶前体的水解和随后缩聚形成。

该核相对于该胶囊总质量的质量分数通常大于50重量%,优选50-99重量%,特别优选60-90重量%。百分数涉及对大量胶囊测定的统计平均值。
