Abstract

本发明公开了一种高保湿增稠剂组合物,按重量份计,包括如下组分:保湿剂1‑16份;增稠剂0.05‑0.5份。本发明通过将特定含量以及特定复配种类的小分子保湿剂与特定含量以及特定复配种类的增稠剂进行复配,一方面,所述小分子保湿剂,根据保湿机理的不同,从多个方面为肌肤提供保湿力,由于分子较小,更易渗透吸收,同时没有大分子保湿剂的黏腻感,令肌肤更加清爽;另一方面,所述增稠剂,既能形成立体且晶莹剔透的啫喱外观,同时在涂抹时可以瞬间化水,增强了涂抹性能和清爽肤感;制成的高保湿增稠组合物应用于化妆品特别是护肤啫喱中,能够赋予产品清爽、易吸收的肤感,同时又具有很好的保湿效果,带给消费者清新水润的使用体验。

Description

一种高保湿增稠剂组合物及其在化妆品中的应用
技术领域
本发明涉及化妆品领域,特别涉及一种高保湿增稠剂组合物及其在化妆品中的应用。
背景技术
干性皮肤最明显的特征是:由于缺乏水分或油分,导致肌肤干燥,容易起皮,不易上妆,缺少光泽,容易产生细小皱纹,对外界刺激比较敏感,易生红斑等多种症状。这种皮肤在寒风烈日、空气干燥的环境或空调环境下,以上症状会更加严重。如长期不加以护理会产生更多更深的皱纹,令肌肤提前衰老。所以干性皮肤必须通过适当的皮肤护理促使其恢复正常生理功能,以防未老先衰。对于缺水性干性肌肤,由于肌肤内部水分与油分失去平衡,导致油脂分泌增加,造成一种“外油内干”的局面。所以说这类肌肤一定要注重补水保湿,帮助皮肤恢复正常生理功能。
护肤啫喱是以护理人体皮肤为主要目的的凝胶状产品,呈现透明或半透明外观。一般来说水性凝胶的啫喱由于添加了较高含量的增稠剂,导致产品肤感较黏腻,难吸收,再加上配方中其他大分子成分,会使整个产品的使用体验较差。
发明内容
本发明旨在给出一种能够赋予产品涂抹时具有高保湿、不黏腻、易吸收的高保湿增稠剂组合物。
本发明所述的高保湿增稠剂组合物,按重量份计,包括如下组分:
保湿剂 1-16份;
增稠剂 0.05-0.5份。
其中,所述保湿剂选自甘油、丙二醇、丁二醇、海藻糖、甜菜碱、吡咯烷酮羧酸钠、交替单胞菌发酵产物提取物、聚乙二醇-8、聚乙二醇-32或甘油聚醚-26中的一种或几种,优选为上述九种保湿剂的复配物。
优选地,所述上述九种保湿剂的复配物的复配重量比为2-4:2-4:2-4:0.1-0.5:0.5-1:0.1-0.3:0.1-0.2:3-5:1-1.5。
本发明所述的高保湿增稠剂组合物中含有特定含量的特定复配种类的小分子保湿剂,其中,所述甘油、丙二醇、丁二醇、海藻糖,能很好的与水分子形成氢键,保持皮肤湿润度;所述甜菜碱,因分子中含有一个正电荷和一个负电荷,正负电荷之间正好能捕捉一个水分子,且随着三甲基基团的转动,水分子能自由进出,即使环境湿度很小时,也会释放出水分子,持续保湿;所述吡咯烷酮羧酸钠与上述小分子保湿剂配合使用不仅可以协同增加保湿效果,同时吡咯烷酮羧酸钠具有柔软粉滑的肤感;所述交替单胞菌发酵产物提取物源自法属波利尼西亚环礁岛边缘的微生物发酵提取物,能刺激皮肤自身水分不断提升,维护并重塑皮肤屏障功能,防止水分大量流失,增强皮肤天然的保湿滋润度;此外,所述甘油聚醚-26、聚乙二醇-8和聚乙二醇-32,能在皮肤表面形成一层防护膜,防止水分散失,同时可以提供柔软不黏腻的肤感。
其中,所述增稠剂选自丙烯酸(酯)类/C10-30 烷醇丙烯酸酯交联聚合物、卡波姆中的一种或两种复配物。
优选地,所述两种复配物的复配重量比为0.05-0.15:0.1。
本发明所述的高保湿增稠剂组合物中含有特定含量的特定复配种类的增稠剂;该复配的增稠剂,能够形成立体且晶莹剔透的啫喱外观,同时在涂抹时可以瞬间化水,增强了涂抹性能和清爽肤感。
基于高保湿增稠剂组合物的总重量,当所述增稠剂的重量份低于0.05份时,制成很稀的溶液,但稀溶液粘度太低,不适合用作护肤啫喱;当所述增稠剂的重量份超过0.5份时,制成很稠的啫喱,由于太稠厚,没有一抹化水的肤感。
本发明还公开了上述高保湿增稠剂组合物在化妆品中的应用,优选在护肤啫喱中的应用。
其中,基于化妆品的总重量,所述增稠剂组合物的添加量为0.5-30wt%。
与现有技术相比,本发明具有如下有益效果:
本发明通过将特定含量以及特定复配种类的小分子保湿剂与特定含量以及特定复配种类的增稠剂进行复配,一方面,所述小分子保湿剂,根据保湿机理的不同,从多个方面为肌肤提供保湿力,由于分子较小,更易渗透吸收,同时没有大分子保湿剂的黏腻感,令肌肤更加清爽;另一方面,所述增稠剂,既能形成立体且晶莹剔透的啫喱外观,同时在涂抹时可以瞬间化水,增强了涂抹性能和清爽肤感;制成的高保湿增稠组合物应用于化妆品特别是护肤啫喱中,能够赋予产品清爽、易吸收的肤感,同时又具有很好的保湿效果,带给消费者清新水润的使用体验。
具体实施方式
下面通过具体实施方式来进一步说明本发明,以下实施例为本发明较佳的实施方式,但本发明的实施方式并不受下述实施例的限制。
各性能指标的测试方法或评价方法:
肤感总体印象的评价方法:将实施例与对比例的护肤啫喱提供给15人左右志愿者试用一周,分别针对产品的以下指标做出评价,按1-5分评价,肤感总体印象平均值=各指标评分×对应的权重/权重总和,并统计平均值;评价标准如表1所示;
表1
稠厚感:产品挤出时的稠厚感,越稠分数越高;
化水性:产品刚一涂开时,瞬间化为水的速度,越快分数越高;
涂抹性:产品涂抹时的顺滑度,越顺滑说明越易涂抹,分数越高;
吸收速度:产品从刚一涂开至完全吸收所用时间,时间越短,吸收也快,分数越高;
粘腻感:用手指涂完产品后,手指与脸部之间的粘合力,越粘,分数越低;
保湿效果:产品吸收完的肌肤保湿感,保湿感越明显分数越高;
温和性:产品使用过程中或用后是否温和,越温和分数越高。
角质层水分含量的测定方法:使用角质层水分测试仪测定角质层水分含量,该参数值越大,皮肤角质层水分含量越高,保湿效果越好。应用SPSS软件对各个测量值进行描述性统计,作Kolmogorov-Smimov Test进行数据正态分布的显著性检验,Sig(双侧)>0.01,则呈正态分布:进行t检验,显著性差异水平α取0.05。若Sig(双侧)<0.01,则呈非正态分布:进行Wilcoxon检验,显著性差异水平α取0.05。
经表皮水分流失的测定方法:使用皮肤水分流失测试仪测定经表皮水分流失,该参数值越小,皮肤屏障作用越高,保湿效果越好。应用SPSS软件对各个测量值进行描述性统计,作Kolmogorov-Smimov Test进行数据正态分布的显著性检验,Sig(双侧)>0.01,则呈正态分布:进行t检验,显著性差异水平α取0.05。若Sig(双侧)<0.01,则呈非正态分布:进行Wilcoxon检验,显著性差异水平α取0.05。
实施例1-7及对比例1-2:添加有高保湿增稠组合物的护肤啫喱
乳化锅中加入水,按照表2的配比称取增稠剂慢慢撒入液面上,完全润湿后,开始搅拌、加热、保温,充分溶胀至均匀液体;按照表2的配比依次投入保湿剂(去除交替单胞菌发酵产物提取物)搅拌至完全溶解无颗粒,抽真空消泡,低速搅拌状态下投入氢氧化钠,搅拌均匀,开始降温,45℃以下投入交替单胞菌发酵产物提取物以及适量的防腐剂,搅拌均匀,送检合格后出料、灌装,即得添加有高保湿增稠组合物的护肤啫喱。所得护肤啫喱的肤感总体印象、角质层水分含量以及经表皮水分流失性能指标的测试结果如表2所示。
表2 实施例1-7及对比例1-2的各组分配比(重量份)
