Description
技术领域
本发明涉及一种化妆品用精华乳液的制备方法，属于化妆品加工领域。
背景技术
皮肤老化是一种持续渐进性的生理过程，直接影响皮肤的外观与功能。 皱纹则是皮肤老化表现的一种标志，被称之为“人生的年轮”。随着人们生活质量的提高，防衰老、去除皱纹、重返青春成了广大消费者关注的话题。为防止皮肤老化，消费者使用各种化妆品以及服用营养品来保养，化妆品市场潜力巨大。目前市场上化妆品成分复杂，传统制备工艺比较落后，由于常添加有油溶性成分，需要依靠大量的乳化剂，并通过高能耗的均质技术才来制成均一乳液。
发明内容
本发明的目的是针对以上关键问题，提供一种化妆品用精华乳液的制备方法。
为实现上述目的，本发明所涉及的化妆品用精华乳液的制备方法包括以下步骤：
（1）取葡萄籽粉碎至50-100目，加入5-50倍质量的5-20wt%乙醇水溶液于30-60℃浸提1-7h得提取液，提取液用硅橡胶复合膜进行渗透汽化分离，收集渗透液；
（2）取聚甘油酯2-4份，溶解于60-80份助溶剂中，加入10-20份步骤（1）中的渗透液，1-4份红景天提取物，搅拌至溶解均匀，制得连续相；
（3）4000-8000rpm转速下剪切步骤（2）中的连续相，并取天然维生素E 8-10份缓慢加入连续相中，继续剪切3-5min至乳状液平均粒径小于2μm，即得化妆品用精华乳液产品。
其中，所述的硅橡胶复合膜为在分离层和支撑层均添加有大孔吸附树脂粉末，所述的大孔吸附树脂为苯乙烯型弱极性共聚体或苯乙烯型非极性共聚体
所述的聚甘油酯为HLB值为12-15的聚甘油酯。
所述的助溶剂为甘油与山梨醇按照3-6:1的质量比复配得到。
与现有技术相比，本发明具有以下优势：
A．本发明制备方法利用特殊的渗透汽化膜对葡萄籽进行渗透汽化提取，渗透液中活性成分纯度高，对防止皮肤氧化衰老效果显著。
B．本发明的乳液的制备方法工艺简单，在4000-8000rpm下剪切3-5min即可制成粒径小于2μm的乳液，而传统上的精华乳液的制备工艺需要利用膏霜机通过剪切和均质两道工序后才能得到均一稳定的乳液，设备投入和能耗高。
C．按本发明的制备方法制备得到的精华乳液稳定，能在0-50℃可以储存36个月以上，状态为澄清透明状，外观表现优秀。
D．按本发明的制备方法制备得到的精华乳液可以作为化妆品成品使用，也可作为化妆品原料使用，当作为原料使用时，由于其是水溶性产品，可以直接添加至化妆品中，此外，作为原料使用时，还能促进化妆品产品体系稳定，尤其是对配方中添加有精油的化妆品，稳定性能提高30%以上。
E．本发明的制备方法中乳化剂添加量少，对皮肤刺激性小。
具体实施方式
以下结合具体实例对本发明的技术方案做进一步的说明。
