Abstract
本发明提供了包含水性载体、水凝胶颗粒和一种或多种表面活性剂的稳定组合物,其中所述水凝胶颗粒含有一种或多种多糖。本发明还提供制备这种组合物的方法。
Description
发明领域
本发明涉及水性组合物及其制备方法。具体说,本发明涉及稳定的水性组合物,其中分散有含多糖的水凝胶颗粒。
相关技术的描述
已知可利用多种组合物为皮肤赋予消费者可感知(例如感觉或视觉感知)的益处。许多这类组合物尝试通过将有效成分(benefit)或活性物,包括润肤油(emollient oil)、油脂、活性颗粒、不溶性无机颗粒沉积到皮肤上,实现消费者可感知的益处。然而,申请人认识到,将这类物质掺入水性组合物中可能导致有效成分与水相发生不良的相分离。
尝试用各种方法解决相分离的问题,包括使用结构化(structured)表面活性剂体系、无机硅酸盐和有机聚合物,参见例如US2009/0005449 A1、WO2008/023145和JP 4182348。然而,仍然需要利用基于天然聚合物的物质为水性组合物提供稳定的悬浮能力的悬浮体系。
发明概述
在一个方面,本发明提供包含水性载体、一种或多种表面活性剂和水凝胶颗粒的组合物,所述水凝胶颗粒包含一种或多种多糖,所述组合物在室温下十天中不发生相分离。
在另一方面,本发明提供包含水性载体、约3重量%或更多阴离子型表面活性剂、水凝胶颗粒的组合物,其中所述水凝胶颗粒含有一种或多种选自角叉菜胶、低酰基结冷胶、低甲氧基果胶和其中两种或更多种的混合物的多糖以及一种或多种交联剂,所述组合物包含大于零至小于0.8重量%的所述多糖和约0.5重量%至约3重量%的所述交联剂。
另一方面,本发明组合物包括将悬浮物质沉积于皮肤、毛发和其他上皮组织以清洁该区域和/或治疗该区域的各种病症,包括但不限于痤疮、皱纹、皮炎、干燥、肌肉痛、瘙痒等的方法。
另一方面,本发明组合物提供治疗和/或清洁人体,更具体是皮肤、毛发和其他上皮组织,以改善该区域的外观/纹理和/或提供额外益处如调理、保湿、柔顺和其中两种或更多种益处的组合的方法。
申请人意外地发现,与其他比较组合物相比,包含a)一种或多种表面活性剂和b)含有一种或多种多糖的水凝胶颗粒的本发明组合物的稳定性倾向于提高。例如,如实施例所述,申请人按照本文所述的稳定性和/或加速稳定性检测测定了本发明组合物和比较组合物的相分离稳定性。虽然比较组合物在室温下约3天内就倾向于发生相分离,但本发明组合物在更高温度下在三倍于该期间的时间中也较稳定。
根据某些实施方式,本发明组合物优选在至少10天的时间中具有按照本文所述稳定性检测测定的相稳定性和/或悬浮珠子(或颗粒)稳定性。在某些更优选的实施方式中,本发明组合物具有相稳定性和/或悬浮珠子(或颗粒)稳定性,优选在至少一个月、更优选至少三个月、更优选约6个月或更长时间中具有相稳定性和悬浮珠子(或颗粒)稳定性。

粒度检测方法:
通过以下测试方法,利用获自中国的马耳文仪器公司(MalvernInstruments,China)的激光-衍射和散射类型设备MS2000测定粒度:
检测空白或参比标准品:将80ml纯化水装入150ml玻璃容器,并用MS2000设备检测。
制备样品溶液和检测:通过混合20ml本发明组合物(凝胶溶液)和60ml纯化水制备样品溶液,然后,以1800rpm搅拌所得溶液直到均一,然后将80ml样品装入150ml烧瓶中,用MS 2000设备检测。
相稳定性检测:
为了测定相稳定性,进行以下检测:将150g样品装入150ml透明塑料容器/瓶中,置于保持在25℃(认为是室温)的稳定性室中。每24小时监测样品的物理性质长达至少1个月或直到观察到相分离为止。如果观察到相分离,则记录下此次观察的时间。
加速相稳定性检测:
为了加速测定相稳定性,进行以下检测:在50℃的测试中,将150g样品装入150ml透明塑料容器/瓶中,并置于保持在50℃的稳定性炉(购自宾得公司(Binder),型号BF115)中;在40℃的测试中,将150g样品装入150ml透明塑料容器/瓶中,并置于保持在40℃的稳定性炉中。每24小时监测样品的物理性质长达至少1个月或直到观察到相分离为止。如果观察到相分离,则记录下此次观察的时间。

表7
实施例21-粒度
按照粒度测试法检测某些本发明组合物样品(实施例3-7和实施例14-15)的粒度,结果参见表8。
表8
实施例22-抗破裂强度
申请人检测了本发明某些组合物的抗破裂强度与交联剂的关系,如下所述。
制备待测凝胶的方法:
在0.5kg大小的制备容器内,在约70℃至90℃的温度下将去离子水和0.5重量%的真胶角叉菜胶CI 102混合在一起,直到真胶角叉菜胶CI 102溶解。在不搅拌的条件下,向反应混合物中加入图1所示量的氯化钾。将该体系冷却至室温,形成凝胶。
通过食品工业中所用的标准测试方法,采用装有0.5英寸(1.27cm)半径的圆筒(P/0.5R)的TA.XTPlus纹理分析仪检测各测试样品的凝胶强度。可使用国际标准测试方法ISO 9665:1998(E)和以下设置:测试模式是压缩,预测试速度是0.5毫米/秒,测试速度是0.5毫米/秒,测试后速度是0.5毫米/秒,目标模式是距离,诱发类型是力,诱发力是5g。通过引用将所述ISO9665:1998(E)测试方法(刊于《国际方法---粘合剂-动物胶-采样和测试方法》(International Method-Adhesives-Animal Glues-Methods of Sampling andTesting),ISO 9665,第二版(1998-09-15))纳入本文。本申请中的所有凝胶强度测定值均为利用此法获得。
结果如图1所示。如图所示,包含真胶角叉菜胶CI 102的测试组合物的凝胶抗断强度因氯化钾浓度不同而不同。在所测试的具体实施方式中,具有优选的稳定性和悬浮特性的优选组合物中氯化钾浓度约为0.3-2.5重量%。
