Description

一种复方间苯二酚脂质体及其制备方法
技术领域
本发明涉及美容领域,具体涉及复方间苯二酚脂质体及其制备方法。
背景技术
随着生活水平的提高,越来越多的人对皮肤的护理有了更高的要求,而白皙皮肤历来被东方女性所崇尚。苯乙基间苯二酚作为一种美白剂,可以有效的减少黑色素的产生,目前广泛的应用在化妆品、护肤品等美容产品中。但苯乙基间苯二酚在实际应用中也存在着一些问题:1、水中溶解度低;2、光稳定性差;3、粒子大,不易渗透进皮肤内等。
为此现有技术中也出现了部分方式,通过将苯乙基间苯二酚混入脂质载体中,制成间苯二酚脂质体,这种方式能够解决溶解度低、光稳定性差等问题,但效果仍然不够理想,还需要对此进行改进,尤其是苯乙基间苯二酚的光稳定度问题,一直不甚理想。
发明内容
本发明的目的在于提供一种利用率高、光稳定性好的复方间苯二酚脂质体及其制备方法。
为实现上述发明目的,本发明所采用的技术方案是:一种复方间苯二酚脂质体,由如下质量百分比计的原材料构成:
苯乙基间苯二酚3%;
4正丁基间苯二酚3%;
4己基间苯二酚3%;
烟酰胺1%;
熊果苷α1%;
传明酸1%;
脂质材料5~10%;
乳化剂3~4%;
增稠剂0.5~2%;
光稳定剂1~1.5%;
余量为水;
所述脂质材料为新葵酸甘油酯,所述乳化剂为大豆卵磷脂,所述增稠剂为硅酸铝镁,所述光稳定剂为二苯甲酰甲烷。
优选的,所述新葵酸甘油酯的质量百分比为8~9%。
优选的,所述大豆卵磷脂的质量百分比为3.2~3.5%。
优选的,所述硅酸铝镁的质量百分比为1.5%。
优选的,所述光稳定剂的质量百分比为1.5%。
优选的,所述复方间苯二酚脂质体的制备方法,包括以下步骤:
A、按配方比例称取脂质材料、乳化剂和光稳定剂,混合后加热至熔融状态,获得液态油相;
B、根据配方称取苯乙基间苯二酚、4正丁基间苯二酚、4己基间苯二酚、烟酰胺、熊果苷α、传明酸,加入所述液态油相并获得均一体系,向所述均一体系中加入水并搅拌均匀,放入预热温度至80摄氏度、压力为100MPa的高压均质机中,并向均质机内加入按配方称取的增稠剂,均质5次,获得高温乳液;
C、将高温乳液冷却至常温获得产品。
本发明的有益效果集中体现在:
1、具有极好的水溶性,有效成分含量高,具有极好的美容美白效果。
2、采用天然的大豆卵磷脂作为乳化剂,无毒无害、生物相容性好。
3、以二苯甲酰甲烷作为光稳定剂加入,能够避免产品变色,极大的延长产品的保质期和防紫外线效果,且能够有效的消除大豆磷脂容易氧化变色的缺陷,提高了产品的储存期。
4、以硅酸铝镁作为增稠剂加入,大大的提升了产品的包封率。
