Abstract
本发明涉及一种皮肤外用剂组合物,其特征在于,所述组合物包括:a)固体颗粒,所述固体粉颗粒为具有表面开孔的多孔质颗粒,并且一次颗粒的平均粒径为0.5~20μm;b)至少一种蜡;c)至少一种基于碳链的油;和d)至少一种表面活性剂,以及,所述组合物任选地包括水,并且,以所述组合物的总质量计,所述水的含量为5%以下。
Description
技术领域
本发明属于化妆品领域,具体涉及用于清洁皮肤的化妆品或卸妆用的组合物。尤其的,本发明涉及一种含水量少或者实质上不含水的固体洗净剂组合物。
背景技术
用于皮肤清洁的组合物已经长久存在,其可以从人体皮肤上清洁或去除老化的角质层、油脂分泌物、污物或化妆品等。
这类组合物通常可以以液态、半固态(例如凝胶)等含水组合物的形式存在。这类常规的个人清洁护理组合物包括卸妆产品、洁面产品、剃须产品等。另外,其通常还可以包含一种或多种成分(例如,香精、防腐剂、表面活性剂等)。近年来面部清洁剂(包括卸妆液)在很多市场已经是面部皮肤护理市场中渗透率最高的子类别。整体上,这些组合物在使用时除了清洁作用以外,还可能会从皮肤除去水分,由此使皮肤感到过于干燥或皴裂而可能导致使用感的不佳。
此外,还有一类组合物以含有少量水或基本上不含有水的固体组合物形式存在,这类组合物在使用于人体皮肤时能够在外力的作用下铺展于皮肤,起到清洁的作用。例如通常被称为“软固体”的一类清洁产品,在使用时能够给消费者带来柔软以及干爽的感觉。
引用文献1公开了一种固体无水组合物,其包含疏水气凝胶颗粒、至少一种具有大于或等于60℃的熔点的蜡、至少一种基于烃的油和至少一种非离子表面活性剂。所述组合物具有改善的卸妆能力、清洗能力和皮肤修饰,并且易于携带,并同时保持良好的卸妆效果。其具有所需硬度以适应于所需设备。
引用文献2公开了一种固体无水组合物,包含a)至少一种疏水性聚合物,所述疏水性聚合物选自由酯封端的聚(酯-酰胺)及其混合物组成的组;b)至少一种烃类油;和c)至少一种非离子表面活性剂。所述组合物用于清洁角蛋白材料和/或从角蛋白材料上卸妆。
另外,现有技术中,对于无水固体清洁类组合物的清洁能力、使用感、卸妆能力和冲洗性已经进行了一定程度的研究,但由于这些固体组合物中存在常温固体(例如蜡等)以及常温液体(例如液态油成分等)组分,在生产、运输以及存储甚至在使用时由于相分离而导致稳定性问题,对于该点,尚没有得到充分的重视和报道。

发明内容
发明要解决的问题
如上所述,现有技术中虽然对于固体清洁用组合物的清洁能力、使用感或水洗性进行了探讨,但本发明在长期进一步的研究中也发现,虽然为了满足上述使用性能在固体组合物中使用了各种常温固体成分以及油类成分,然而,这同样可能引入了稳定性问题。
例如,在生产、运输、存储甚至使用过程中,固体组合物可能会经历震动(例如导致非常规平稳形态矗立)、温度变化等外部影响,其中的固体成分(包括固体的蜡质成分)与油类等液体成分可能会产生相分离,因此可能会造成外观以及使用感甚至是清洁性能的下降。尤其地,这样的现象在对固体组合物施加一段时间的较大温差经历后变得尤其明显。
因此,本发明所要提供的是一种皮肤外用剂组合物,其是一种含有少量水或实质上不含有水的固体清洁用组合物,该组合物不仅具有良好的清洁性、舒适的使用性以及水洗性,同时也具有改善的稳定性,能够避免在外界机械力或温度变化的影响下产生相分离。

本发明涉及一种皮肤外用剂组合物,在一些具体的实施方案中,其为一种含水量极少或实质上不含有水的皮肤清洁用组合物。
本发明的皮肤外用剂组合物主要包括:固体颗粒,所述固体颗粒为具有表面开孔的多孔质粉末(以下也称为“固体粉末状颗粒”),以及必要的蜡质成分、油质成分以及表面活性剂。在一些优选的实施方案中,以所述组合物的总质量计,所述水的含量为5%以下。
(固体粉末状颗粒)
本发明的皮肤外用剂组合物中含有固体粉末状颗粒,并且,本发明的固体粉末状颗粒为具有表面开孔的多孔质固体颗粒或多孔质固体粉末。
本发明中,所述的多孔质固体颗粒或者多孔质固体粉末,在所述的皮肤外用剂组合物中,以主要一次颗粒的形式存在。在一些具体的实施方案中,这些以一次颗粒形式存在的固体颗粒或粉末占所有颗粒或粉末的总质量的90%以上,优选为95%以上,进一步优选为98%以上。
本发明所述“一次颗粒”指的是以单个颗粒状态存在的颗粒,其在存在状态上区分于“二次颗粒”,后者指的是固体颗粒由于粒径非常小,因而由于表面能高而使得若干单个颗粒聚集在一起而形成聚集态颗粒,例如气凝胶类物质。
在本发明一些具体的实施方案中,本发明的一次颗粒具有0.5~20μm的平均一次粒径(D50),优选为3~18μm,进一步优选为4~15μm。一次颗粒的平均粒径过小可能导致一次颗粒团聚而生成二次颗粒进而对于本发明所述的组合物的稳定性有产生劣化的趋势;一次颗粒的平均粒径过大,则可能对于本发明皮肤外用剂组合物在使用时的舒适感造成不利影响,例如过度的颗粒感或过强的摩擦感。
本发明上述的多孔质固体颗粒或粉末,可以选自表面具有开孔结构的二氧化硅颗粒、经过表面改性的二氧化硅颗粒或者基于有机聚合物的颗粒或者它们的混合物,优选地,出于使用感、材料的抗热膨胀收缩性以及安全性的考虑,对于本发明的多孔质固体颗粒或粉末优选为表面具有开孔结构的二氧化硅颗粒。另外,在一些具体的实施方案,本发明的多孔质固体颗粒或粉末可以为疏水性的颗粒或粉末。
进一步,对于表面改性的二氧化硅,可以为表面经由树脂或橡胶改性的二氧化硅颗粒,例如硅树脂或者硅橡胶等;对于基于有机聚合物的颗粒,可以选自交联或未交联的有机聚合物材质的颗粒,可以列举例如(甲基)丙烯酸酯树脂、聚酰胺树脂(尼龙粉末)、聚乙烯、聚苯乙烯、苯乙烯与(甲基)丙烯酸的共聚物树脂、苯并胍胺树脂、聚四氟乙烯、纤维素、和有机硅酮树脂、硅酮橡胶等形成的颗粒,或以它们两种以上的物质形成的复合(例如核壳型)颗粒。
对于本发明的多孔质固体颗粒或粉末表面具有的开孔结构,所述“开孔”是指在颗粒或粉末表面上存在与外部相连通的孔。
在一些具体的实施方案中,这些开孔的平均孔径为7.5nm以上,或者为8nm以上,或者为10nm以上,或者为12nm以上;对于所述开孔的平均孔径的上限,在一些具体的实施方案中,所述开孔的平均孔径为50nm以下,或者为30nm以下,或者为20nm以下。进一步,在本发明一些优选的实施方案中,所述开孔的平均孔径优选为7.5~15nm。
对于本发明上述的表面开孔的平均孔径可以借助现有的方法进行测定。典型地,可以借助气体吸附法分析测试的标准测定,其在液氮温度下利用氮气吸附法进行,对得到的数据采用Barret,Joyner和Halenda方法(简写为BJH方法)处理以得到最终测定值。
对于本发明上述多孔质固体颗粒的比表面积,在一些具体的实施方案中,可以为400m2/g以下,优选为80至400m2/g或100至400m2/g,进一步优选为200至350m2/g。对于本发明的比表面积,可以经由描述于Journal of the American Chemical Society,第60卷,第309页,1938年2月且对应于国际标准ISO 5794/1(附录D)的BET(Brunauer-Emmett-Teller)氮气吸附法来确定。BET比表面积对应于被测试的颗粒的总比表面积。
另外,对于本发明的上述多孔质固体颗粒的吸油量,没有特别限制,其与比表面积以及粒径存在关联。但从本发明的皮肤外用剂组合物的稳定性角度考虑,本发明的多孔质固体颗粒具有300%以下的吸油量,优选为50~250%或100~250%。对于吸油量的测量,可以通过现有技术进行测量,例如依据湿点法或描述于标准NF T 30-022中的用于确定粉末吸油量的方法来测定。
本发明中,认为使用具有上文限定特征的多孔质固体颗粒或固体粉末,在将其与本发明的皮肤外用剂组合物中其他成分进行混合时,有利于避免由于相分离所产生的稳定性变差的问题。
本发明通过研究,推测上述效果可能是由于以下机理而导致:本发明的皮肤外用剂组合物中,以蜡质成分作为主要常温固体成分,同时与油质成分、固体颗粒以及表面活性等进行混合。混合过程中,油质成分能够进入固体颗粒表面开孔中,也即,表面开孔结构对进入的油质成分起到了锚定作用。进而最终形成的皮肤外用剂组合物即使经历了外部的机械力的刺激(例如运输或使用时的震动)或者温度变化刺激(例如经历由于存储条件或由于地域、季节差异所导致的温度变化)后仍然能够避免油质成分从皮肤外用剂组合物中的固相分离、析出,进而提高本发明的皮肤外用剂组合物的整体稳定性,并保持原有的使用性和清洁能力。并且,这样的锚定作用即使在多孔质固体颗粒的含量为10%以下时,也能很好的体现。
(蜡质成分)
本发明的皮肤外用剂组合物中,包括蜡质成分。
本发明中,所述蜡质成分,指的是在室温条件下呈现出固体的脂类化合物成分。
