Abstract

本发明公开了一种可模塑凝胶清洁剂,其包含卡拉胶、钾源和二醇。

Description

可模塑凝胶清洁剂
技术领域
本发明涉及个人护理产品,尤其是具有改善特性的可模塑凝胶清洁剂。
背景技术
消费者喜欢用于多种个人护理用途的产生泡沫的产品,诸如洗发剂和沐浴露、面部清洁剂和剃刮制剂凝胶。基于泡沫的个人护理产品令人感到愉悦。消费者特别喜欢高稠度泡沫、快速起泡行为、持久的泡沫、以及丰富、奢华、乳脂状泡沫的感觉。为了达到这些期望的效果,将表面活性剂添加到许多个人护理产品中。表面活性剂通过降低液-气界面的动态表面张力以允许在液体表面下方形成或引入气泡而在产生泡沫的产品中发挥主要作用。一旦形成泡沫,表面活性剂还能稳定泡沫。然而,表面活性剂也并非没有缺点。例如,已知一些表面活性剂诸如硫酸盐(包括烷基硫酸盐和烷基醚硫酸盐)对皮肤具有刺激性。
众所周知,通过将表面活性剂与海藻提取物混合,可制得化妆品胶状物。此类产品已在商业上出售,但至少部分地由于胶状物的特性而未被广泛采用。即,已知的美容胶状物具有半液体形式,并且当例如与水一起施用于人体时,它们分解成块状糊剂的稠度。
授予Cosmetic Warriors,Ltd.的美国公开申请号20080206273公开了一种包含表面活性剂、甘油、单丙二醇和任选的卡拉胶的化妆产品。该参考文献公开了包含与甘油混合的单丙二醇对胶状物的稠度具有影响,从而导致胶状物具有耐用且几乎橡胶样的质地。该参考文献还公开了当胶状物含有海藻提取物时,效果是出人意料的,因为据认为这种提取物将因甘油和单丙二醇的存在而不稳定。该美国专利申请对应于国际公开申请号WO2006067400,于2010年被放弃。
授予FMC Corporation的美国专利9,028,872公开了泡沫、制备方法及其用途。该参考文献公开了可用于个人护理应用中的泡沫优选地为多糖,并且用于制备泡沫的适宜多糖的示例包括藻酸盐、果胶、卡拉胶、透明质酸盐、脱乙酰壳多糖、以及它们的混合物。
授予Y&B Mother's Choice Ltd.的美国专利10,064,881公开了含有天然获得的植物提取物的组合物,该天然获得的植物提取物含有天然获得的皂苷材料。该参考文献公开了卡拉胶可用作组合物中的增稠剂。
本发明试图改善先前已知的化妆品胶状物。
发明内容
学步儿很难养成健康的手洗习惯。如果护理人员从孩子出生起为孩子使用有趣、有效的清洁剂,则孩子将回忆起使用清洁剂时的积极体验,而且往后会倾向于洗手。本发明的可模塑凝胶清洁剂以有趣的、感官丰富的形式促进健康的洗手习惯。
本发明是一种具有可模塑形式和质地的凝胶清洁剂,该凝胶清洁剂具有的卡拉胶的量能有效地为消费者带来丰富的感官体验。此外,该可模塑凝胶清洁剂不含硫酸盐,因此它对婴儿和学步儿是温和的。由于钾离子的存在,可模塑凝胶清洁剂具有凝胶基质,正因如此,可模塑凝胶清洁剂具有凝胶状质地。可模塑凝胶清洁剂包含二醇,其防止海绵状,有助于可模塑凝胶清洁剂的稳定性和结构,并且赋予可模塑凝胶清洁剂光滑的表面。
根据本发明的第一方面,提供了一种个人护理产品,其包含:
卡拉胶;
钾离子源;和
二醇。
卡拉胶用作胶凝剂。可模塑凝胶清洁剂的形式可根据产品中卡拉胶的量而不同。卡拉胶可为包含K型卡拉胶和I型卡拉胶的卡拉胶的共混物。根据K型卡拉胶和I型卡拉胶的比率,实现了不同的形式、质地、固定脱水收缩和冻融稳定性。
强效、耐用多次使用的形式
为了形成强效、耐用多次使用的胶状物清洁剂,优选地,该个人护理产品包含至少1.5%,但小于2.0%的K型卡拉胶。没有足够的卡拉胶将导致可模塑凝胶清洁剂在使用时易碎,而卡拉胶过多将压缩凝胶基质并使其凝胶化程度降低,从而最大限度地减少感官体验。最优选地,具有这种形式的个人护理产品包含1.75%的K型卡拉胶。
可压碎的单次使用(易碎)的形式
为了形成具有易碎质地的可压碎的单次使用的胶状清洁剂,优选地,该个人护理产品包含约0.63%至约0.75%的K型卡拉胶。0.1%-0.5%的CaCl2(其使得K型卡拉胶易脆且易碎)可在易碎形式中用来增加压碎后的表面积。

样形式
为了形成
Figure BDA0003208342360000032
样胶状清洁剂,优选地,该个人护理产品包含1.5%至2.0%,并且更优选地1.75%的卡拉胶,卡拉胶的比率为50:50–75:25的I型卡拉胶:K型卡拉胶。比率为75:25的I型卡拉胶:K型卡拉胶形成光滑的果冻质地。更优选地,卡拉胶的共混物包含比率为0.88:2.62的K型卡拉胶:I型卡拉胶。
优选地,该个人护理产品包含0.25%至1.0%,并且更优选0.5%的钾离子源。优选地,钾离子源为山梨酸钾。山梨酸钾还用作本发明的可模塑凝胶清洁剂中的防腐剂。
优选地,个人护理产品包含2.5%至7%,更优选5%至6%的二醇。优选地,二醇为丁二醇。二醇用作本发明的可模塑凝胶清洁剂中的湿润剂。
优选地,个人护理产品还包含10%至30%,更优选15%至25%的表面活性剂。因此,根据本发明的另一方面,提供了一种个人护理产品,其包含:
卡拉胶;
钾离子源;
二醇;和
表面活性剂。
优选地,表面活性剂为包含甲基椰油酰基牛磺酸钠、椰油酰胺丙基甜菜碱和癸基葡糖苷的表面活性剂体系。更优选地,表面活性剂体系包含1:2:1(阴离子:两性:非离子)比率的甲基椰油酰基牛磺酸钠、椰油酰胺丙基甜菜碱和癸基葡糖苷。癸基葡糖苷在本发明的可模塑凝胶清洁剂中促进发泡。
根据本发明的另一个方面,提供了制造个人护理产品的方法,该个人护理产品包含:卡拉胶、钾离子源、二醇,并且优选地包含表面活性剂。
根据本发明的另一方面,可使可模塑凝胶清洁剂的表面积最大化以增强发泡并减少滑动。
本文的发明人已发现,包含卡拉胶、钾离子和二醇对可模塑凝胶清洁剂的稠度具有显著的影响。
本发明的强效、耐用多次使用的形式的可模塑凝胶清洁剂可特别用作个人护理产品,因为它不像常规化妆品胶状物那样容易分解。因此,它特别适合用作沐浴凝胶或沐浴露,其中它可以一定程度上类似于常规皂条的方式施用。所有可模塑凝胶清洁剂形式也适合用作例如洗发剂。
具体实施方式
定义
“卡拉胶”是从红色可食用海藻中提取的直链硫酸化多糖。卡拉胶是以交替的α-1,3和β-1,4糖苷键连接的D-吡喃半乳糖基单元的链。存在三种主要类型的卡拉胶,其硫酸化度不同。K型卡拉胶的每个二糖具有一个硫酸根基团,I型卡拉胶的每个二糖具有两个硫酸根基团,并且L型卡拉胶的每个二糖具有三个硫酸根基团。
“快速发泡”是指物质在发泡期间的泡沫形成行为,即,产生的泡沫量取决于时间或能量输入。
“凝胶”是软的、部分透明的半固体物质。
“胶凝剂”是添加到组合物中以提供凝胶质地的物质。
“湿润剂”是保留水分的物质。
“硫酸盐”是当硫酸与另一种化学物质反应时形成的盐。消费者可能关注的是针对其它合成的基于硫酸盐的化学品的更广泛的术语,诸如月桂基硫酸钠(SLS)和月桂基聚氧乙烯醚硫酸钠(SLES)。由石油和植物来源如椰子油和棕榈油制得的这些化合物存在于清洁和个人护理产品中。SLS和SLES在产品中的主要用途是产生泡沫。
“表面活性剂”是降低两种液体之间、气体和液体之间、或者液体和固体之间的表面张力(或界面张力)的化合物。表面活性剂可用作洗涤剂、润湿剂、乳化剂、发泡剂和分散剂。
“脱水收缩”是伴有液体分离的凝胶收缩。
据观察,卡拉胶和钾离子源的组合形成了强效、透明的凝胶,并且能够支持表面活性剂体系。
还观察到,卡拉胶类型的特定比率影响质地、脱水收缩、冻/融稳定性和破碎。
还观察到,表面活性剂的特定组合增强了产品的清洁方面(例如,快速发泡、泡沫寿命、泡沫质量/密度、温和性和皮肤后感)。
本发明实现了在适当的泡沫分布之间的平衡,同时保持足够温和以保持皮肤柔软和受调理。
现在将仅以进一步举例的方式描述本发明的实施方案。
根据本发明的实施方案的可模塑凝胶清洁剂由表1中的组分形成,其中百分比按重量计给出。

本发明人确定:
卡拉胶形成固体胶状物。
山梨酸钾是良好的防腐剂/交联剂。
1.5%-2%的K型卡拉胶在强效、耐用多次使用的形式和
Figure BDA0003208342360000112
形式中效果良好。
1.75%的K型卡拉胶在强效、耐用多次使用的形式和
Figure BDA0003208342360000113
形式中效果最好。
甘氨酸盐是不相容的,如使用椰油酰甘氨酸钾所表现出的。
I型卡拉胶本身效果不佳。I型卡拉胶和K型卡拉胶的共混物效果良好。
PEG-80和任何多乙氧基化化合物与卡拉胶不相容。
I型卡拉胶/K型卡拉胶共混物的最佳卡拉胶比率为0.88:2.62。
实施例
对表面活性剂进行测试。结果示于表5中。如下文可见,并非所有的表面活性剂都与本发明的可模塑凝胶清洁剂相容。

实施例
泡沫高度
泡沫高度测试是客观量化发泡性能的一种有价值的方法。其由翻滚仪器执行以确保再现性。该方法涉及用90g水和10g产品将滚筒倒置达32个循环。在2、4、8、16和32个循环之后收集数据。
更多的泡沫是优选的。
快速发泡是重要的。
循环2-8、循环16-32。
有助于量化清洁剂的性能。
实施例
脱水收缩实验方法
1.形成批量并倾倒(2)半球形样品,使其完全冷却。
2.一旦冷却,便记录质量。
a.如果是露天测试,则继续步骤3-11。
b.如果是封闭测试,则转到步骤12。
3.取一个标准压舌板并记录其质量。
4.将压舌板刺穿其中一个胶状物,使得棒状物与半球的平坦侧平行。
5.记录胶状物+棒状物的质量。
6.将压舌板放在400mL烧杯的整个口中,因此胶状物悬浮在空气中。
7.记录当前时间。
8.在24小时内,记录样品+棒状物的质量。
9.在48小时内,记录样品+棒状物的质量。
10.在72小时内,记录样品+棒状物的质量。
