Description

一种含有丝精的凝胶及其制备方法
技术领域
本发明属于日化用品制备技术领域,具体涉及一种含有丝精的凝胶及其制备方法。
背景技术
丝精是采用现代生化技术,将丝素蛋白水解为一定比例的多肽和氨基酸后,再经提纯和精制而得的天然蚕丝的复合氨基酸与二肽、三肽的混合物。丝精中含有一定分子量的具有生理活性的水溶性丝素多肽(二肽和三肽),易被人体吸收,对降解人体血液中的血糖和胆固醇等具有一定的预防保健功能。丝精具有卓越的保湿性能,丝精中所含的游离复合氨基酸和低分子量二肽和三肽与人体皮肤和毛发有很好的亲和性,能渗透过皮肤和毛发的角质层达到其内部,提供丰富的营养成分,在护肤类化妆品中添加丝精时,丝精的低聚肽可渗透到皮肤的角质层,并参与体内酶的活动,很快被皮肤同化和吸收,达到护肤、润肤及养肤的功效。丝精以其优良的生理活性肽特征,在食品和医药保健及化妆品中有着广泛的应用前景。目前丝精用于日化用品系列产品非常少,因此需要开发一种含有丝精的护肤产品,进而拓展其应用领域。
发明内容
本发明的目的是克服现有技术的不足而提供一种含有丝精的凝胶及其制备方法,所得凝胶具有良好的吸水性、透水性、透湿性及良好的生物相容性。

进一步地,聚乙二醇为聚乙二醇600。
上述含有丝精的凝胶的制备方法,包括以下步骤:
步骤一,按照重量份称取各组分;
步骤二,将对二甲基氨基苯甲酸异辛酯,对羟基苯甲酸甲酯,丙三醇,丙二醇,柠檬酸,聚乙二醇,丁二醇和透明质酸钠加入到反应釜中,在惰性气体保护的条件下,升温至50-60℃,保持10-20分钟,得到混合物一;
步骤三,将剩余组分加入到混合物一中,加热至50-60℃,搅拌5-10分钟,然后降温至4℃,静置保持3-5h,得到含有丝精的凝胶。
进一步地,步骤二中惰性气体为氮气或氩气。
进一步地,步骤二中升温至50-60℃的过程为以3-5℃/分钟的速度升温至50-60℃。
进一步地,步骤三中降温至4℃为以5-6℃/分钟的速度降温至4℃。
