Description

易卸妆的皮肤用打底化妆品 技术领域
本发明涉及皮肤用打底化妆品，特别是涉及可以不使用专业卸除彩妆的卸妆用品，仅用普通洗面奶就可以与彩妆一起容易地从皮肤除去的皮肤用打底化妆品。
背景技术
粉底等彩妆通常含有大量油分或其它油性成分，因此卸妆时通常必须使用专门针对彩妆的卸妆品才能清除干净。另外，耐水性、耐皮脂性、持妆性等得到了显著提高的所谓持久型或防水型粉底是采用通常的卸妆品或洗面品难以除掉的处方，因此必需使用专用的卸妆品。
卸妆时需要使用专用卸妆品或洗面品对使用者来说在时间、费用上是一种负担，另外，还有的使用者担心专用彩妆卸妆品或洗面品对眼睛或皮肤的刺激，不使用专用卸妆品。
因此，如果能开发出不用专用彩妆卸妆品或洗面品就能容易地卸妆的产品，则可以减轻使用者的负担或担心，而且会大大方便使用者。
近年来，本公司已开发了用温水可以除掉的化妆品。例如专利文献1(CN1048533740B)中记载了可以用温水除掉的皮肤用打底化妆品。但是这样的化妆品存在如下的主要问题：其一就是持妆性不足，有时会因为运动或环境温度高导致大量出汗，温热的汗液导致发生脱妆或花妆。其二就是消费者普遍认为仅仅用温水就可以完全卸妆是不可信的，怀疑仅用温水即可卸妆的产品的洗净力，通常还是会使用卸妆品进行卸妆。

发明概要
发明所要解决的课题
妆前乳(粉底液)的持妆性和易卸妆性对于消费者来说是重要的。人们需要耐汗性、耐水性强、持妆性强、不容易脱妆或花妆，且用普通的洁面产品就能简单除去的打底化妆品。本发明是鉴于前述背景技术而完成的，目的是提供一种在涂布粉底等之前涂布在皮肤上的皮肤用打底化妆品，该皮肤用打底化妆品不会被汗液、泪水或温水等弄花或除掉，仅用普通的洁面产品清洁时，就可以与彩妆一起容易地从皮肤除去。耐汗性、耐水性、耐温水性、持妆性有很大提高，不易脱妆或花妆，而且用普通洁面产品就能简单干净地除去，洗净力充分。

在皮肤上涂布本发明的易卸妆的皮肤用打底化妆品所形成的打底被膜持妆性好，进一步涂布在其上的皮肤用彩妆化妆品可以持久保持上妆，不会因运动、热环境下的出汗或流泪等导致脱妆或花妆，表现出非常优异的持妆性。另一方面，本发明的易卸妆的皮肤用打底化妆品，仅用普通的洁面产品清洁皮肤时，就可以使打底被膜均匀溶解，连同附着在其上的彩妆一同，很容易从皮肤上清除干净。即本发明的皮肤用打底化妆品实现了持妆性和洗净力两方面同时优异的性能。
具体实施方式
持妆性和易卸妆性是对立的两种性质，持妆性优异的化妆品往往难以简易清除，需要特定的卸妆产品才能清除，比较麻烦。而卸妆性好容易简单去除 的化妆品往往持妆性差，上妆一段时间就出现花妆，或因运动或温热环境导致的出汗而引起脱妆。因此要实现持妆性和易卸妆性两方面都优异是很难的。本发明者进行了深入研究，结果发现通过在化妆品中含有特定量的(a)选自丙烯酸酯类的成膜剂，(b)选自HLB10-16的亲水性非离子表面活性剂，(c)多元醇，(d)阳离子表面活性剂，通过它们的协同作用，可以实现打底化妆品的持妆性和易卸妆性两方面都优异的效果的，并因此完成了本发明。
下面具体说明各个组分。
(a)成膜剂
本发明的易卸妆的打底用化妆品中选择使用特定的成膜剂，即丙烯酸酯类的成膜剂。
所述丙烯酸类成膜剂是水溶性高分子聚合物，选自丙烯酸(酯)类聚合物、苯乙烯/丙烯酸(酯)类共聚物中的一种或其组合。例如丙烯酸酯类聚合物5000AS(大东化成)、苯乙烯/丙烯酸酯类聚合物5000-STY(大东化成)、丙烯酸酯类聚合物Yodosol GH34F等。
本发明者发现，通过选择这样的特定的成膜剂，与特定的多元醇、阳离子表面活性剂以及亲水性非离子表面活性剂组合使用，可以提高持妆性，且可通过普通的洁面产品容易地去除，具有优异的洗净力。
丙烯酸酯类成膜剂在本发明的皮肤用打底化妆品中，以质量百分比分计为1～15％、优选2～7％，更优选5％-6％。丙烯酸酯类成膜剂以上述范围在皮肤打底用化妆品中含有时，可以同时实现持妆性的优异以及易卸妆性。丙烯酸酯类成膜剂含有量过少时，有时成膜不好，导致在其上上妆的彩妆持妆性差。另一方面，丙烯酸酯类成膜剂含有过多时，会导致打底化妆品的涂展性变差，而且易卸妆性变差。
(b)亲水性非离子型表面活性剂
本发明的易卸妆皮肤打底用化妆品中使用的亲水性非离子型表面活性剂，要使用选自HLB10-16的亲水性非离子表面活性剂。
作为HLB10-16的亲水性非离子型表面活性剂，可以列举例如POE脱水山梨糖醇脂肪酸酯、POE山梨糖醇脂肪酸酯、蔗糖脂肪酸酯、甘油或聚甘油脂肪 酸酯、脂环醇聚氧乙烯醚、丙二醇脂肪酸酯、POE甘油脂肪酸酯、POE脂肪酸酯、POE烷基醚、POE烷基苯基醚、POE·POP烷基醚、POE蓖麻油或POE氢化蓖麻油衍生物、POE蜂蜡-羊毛脂衍生物、烷醇酰胺类、POE丙二醇脂肪酸酯类、POE烷基胺、POE脂肪酸酰胺、烷基酰胺胺等，可以将这些中的1种或2种以上组合配混，其中特别优选聚山梨醇酯-60、蔗糖硬脂酸酯、PEG-20甘油异硬脂酸酯、PEG-60甘油异硬脂酸酯、聚甘油六酯。
使用HLB值不在10-16的亲水性非离子表面活性剂，不能获得本发明的耐温水性优异、持妆性优异的效果。
(b)亲水性非离子型表面活性剂在本发明的打底化妆品中的使用量没有特别的限制，优选为0.2-5质量％，更优选为1-5质量％、进一步优选为1.5-4.5质量％。亲水性非离子型表面活性剂不在上述范围时，本发明的皮肤用打底化妆品不能实现耐温水性、持妆性和易卸妆性同时优异的效果。
(c)多元醇
本发明中所用的多元醇是分子内具有2个以上、优选具有2～6个羟基的水溶性饱和脂肪族醇(分子内可以含有醚键)，可以使用通常在化妆品等中配混的成分。
多元醇可以列举3元醇(例如甘油、三羟甲基丙烷等)、4元醇(例如双甘油、赤藓醇、季戊四醇等)、5元醇(例如木糖醇、三甘油等)、6元醇(例如山梨糖醇、甘露糖醇等)、以及它们的聚合物(例如双甘油、三甘油、四甘油、聚甘油等)等，但优选的多元醇例子可以列举二醇(分子内具有两个羟基的醇)。
二醇可以列举例如乙二醇、二甘醇、三甘醇、四甘醇、聚乙二醇、丙二醇、1,3-丙二醇、一缩二丙二醇、聚丙二醇、1,3-丁二醇、1,2-丁二醇、1,4-丁二醇、2,3-丁二醇等。
其中，特别优选一缩二丙二醇、丙二醇、1,3-丁二醇、聚乙二醇(例如分子量为500以下)。
本发明的皮肤用打底化妆品中，(c)多元醇的含量，以质量百分记含有2-8％。在上述范围含有上述特定的多元醇，与上述丙烯酸酯类成膜剂、非离 子表面活性剂以及后述的阳离子表面活性剂协同作用，可以实现本发明的皮肤用打底化妆品的耐温水性、持妆性和易卸妆性同时优异的效果。
(d)阳离子表面活性剂
本申请人在以前发明的用温水可以除去的打底用化妆品(请参见专利文献1)中，明确记载了离子性表面活性剂会影响发明效果，因而优选尽可能抑制离子性表面活性剂的配混量，优选不配混离子性表面活性剂。
但是，本发明的发明者意外发现，通过在本发明的打底化妆品中与特定的成膜剂、亲水性非离子表面活性剂以及多元醇一起，含有特定的阳离子表面活性剂，可以获得更好的持妆性，防止汗液、泪水或温水导致的脱妆或花妆，而且在获得优异持妆性的同时，用以简便地用普通洁面产品清除，洗净力也优异。
可以在本发明的易卸妆使用的阳离子型表面活性剂，可列举，二硬脂基二甲基氯化铵DSV、咪唑林型阳离子表面活性剂，季铵盐-33等。
本发明的皮肤用打底化妆品中，(d)阳离子表面活性剂的含量以质量百分比计，含有0.2％-0.8％，更优选含有0.4％-0.6％。阳离子表面活性剂含量大于0.8％时，会导致洗净力不足，不容易清洗干净，含量少于0.2％时，耐温水性变差，容易因汗液或泪液导致脱妆或花妆，持妆性变差。
其它成分
本发明中，除了上述必需成分以外，还可以在不损害本发明效果的范围内配混通常在化妆品中使用的成分。作为其他成分，可以列举例如水，以及其他添加物，例如，皮肤调理剂、液体油脂、烃油、酯油、蜡、硅油、有机硅、水溶性增稠类成分、其他表面活性剂、保湿剂、防腐剂、金属离子掩蔽剂、粉末成分、色素、pH调节剂、皮肤营养剂、维生素、香料等等。

本发明的皮肤用打底化妆品是在粉底等彩妆之前涂布在皮肤上的物质，不是用于睫毛或眉毛的打底化妆品。另外，通常粉底这样的彩妆化妆品含有大量着色材料，但本发明由于是皮肤用打底化妆品，几乎不含着色材料。本发明的皮肤用打底化妆品中，着色材料(有色颜料、白色颜料、体质颜料、色素等)合计低于3质量％、优选低于1质量％。另一方面，涂布在本发明的皮肤用打底化妆品之上的皮肤用彩妆化妆品可以含有着色材料(有色颜料、白色颜料、体质颜料、色素等)合计1质量％以上、甚至是合计3质量％以上。例如，在本发明的皮肤用打底化妆品之后涂布的皮肤用彩妆化妆品可以列举液态粉底、膏状粉底、粉状粉底、腮红、扑粉、眼影、遮瑕霜、口红、唇膏等。
本发明的皮肤用打底化妆品是在涂布粉底等皮肤用彩妆化妆品之前涂布到皮肤上。本发明的打底化妆品对温水耐性良好，即使是被汗液、泪水或温水沾湿，也不会被除掉或崩解。另一方面，在使用普通的洁面产品清洁皮肤时，由于洁面产品中含有的多元醇组分和本发明的打底化妆品中含有的多元醇一起，使得本发明的打底化妆品中的成膜剂溶解，从而使得本发明的打底化妆品以及在打底皮膜上附着的彩妆化妆品一起溶解，使得使用者可以简便的除去打底化妆品和彩妆。
实施例
以下列举具体例进一步说明本发明，但本发明不限于这些具体例。配混量只要没有特别说明是指质量％。
实施例产品制备方法如下：
a)将属于油相的各组分加入油相锅中，加热至80-85℃，保证固体成分完全溶解后均质，形成均一的油相混合物。
b)将属于水相的各组分加入油相锅中，加热至75-85℃，保证固体成分完全溶解后均质，形成均一的水相混合物。
c)将油相和水相混合物分别抽入真空乳化锅中，然后以转速为7000rpm，在80-85℃下均质至乳化均匀，再将转速降为2000-3000rpm，降温至40- 50℃，添加成膜剂，防毒剂等其它成分，以转速为5000rpm在40-50℃下搅拌至均匀后出料。
另外，关于本发明的打底用化妆品的持妆性、温水耐性、洗净力的效果评价采用如下方法：
(一)温水耐性、洗净力试验
1.涂抹样品
将实施例中得到的打底化妆品料体由内向外打圈圈三次使料体广泛铺展于上臂内侧皮肤表面，涂抹面积：4cmX4cm，涂抹量：32mg(2mg/cm 2)。然后，用手指横向5下，纵向5下，以此为一个循环。共完成3个循环。等待10分钟，让它变干。
2.涂抹粉底液
使用市售的粉底液涂抹在上述打底化妆品上面，涂抹量和手法参照上述1中涂抹样品的方式。等待10分钟，让它变干。
3.清洗
温水洗：在恒温水浴(本次是和40℃)中，用手取水轻轻摩擦胳膊50次。
洗面奶洗：用常温水(25℃)并使用洗面奶，用手取水轻轻摩擦胳膊50次。

从上述结果可知，实施例1-2不含丙烯酸脂类成膜剂，因而耐温水性、持妆性不如含丙烯酸脂类成膜剂的打底化妆品效果好。实施例1-3中不含多元醇，所以洗净力差，实施例1-4中不含阳离子表面活性剂，因而耐温水性差，实施例1-5中不含HLB值10-16的非离子亲水性表面活性剂，因而洗净力差。由此可知，只有同时含有选自丙烯酸酯类的成膜剂、选自HLB10-16的亲水性非离子表面活性剂、多元醇、阳离子表面活性剂的打底化妆品，在洗净力、耐温水性、持妆性三方面都是优异的。
