Description

一种弱碱性水溶解的蛋白肽保湿液及其制备方法 技术领域
本发明属于保湿材料技术领域,涉及一种弱碱性水溶解的蛋白肽保湿液及其制备方法。
背景技术
在所有的化妆品原料当中,保湿剂占有非常重要的地位。一方面,几乎所有的化妆品配方都离不开保湿剂,它是组成化妆品的基础物质之一;另一方面保湿剂对化妆品的功能与质量起着至关重要的作用,从某种意义上讲保湿剂决定了化妆品的品质。
近几年来人们对于皮肤保湿有了全新的认识,人们已经不再满足于过去的油脂护肤而是对一些清爽的补水保湿产品情有独钟。因此,各种各样的保湿剂及保湿产品便应运而生,其市场前景非常可观。
保湿剂是一类能从潮湿空气中吸收水分的吸湿性物质。保湿剂通过吸收和保持水分达到保湿、滋润、恢复肌肤弹性等功效。过去人们错误地认为皮肤干燥是由于皮肤表面缺乏脂类物质,现在经过一系列实验证明如果仅在干燥皮肤表面涂擦油脂并不能使其变得柔软,因为皮肤干燥的真正原因是角质层中水分不足。皮肤角质层起控制外皮水分损失的壁垒作用为保持皮肤水分的平衡,角质物质应保持一定的水分以对抗外界环境的湿度变化,也就是说,要使皮肤光滑、柔软和富有弹性,必须使皮肤中角质层的含水量保持最佳状态。一般认为角质层的含水量应在10~20%之间,低于10%,皮肤就会干燥、粗糙甚至皲裂。因此,人们将能保持皮肤角质层水分的物质统称为保湿剂。
目前,在化妆品领域常用的保湿剂有甘油和透明质酸。甘油是化妆品中使用最早、目前应用最普遍的保湿剂,甘油分子中含有三个-OH,与水分子形成氢键,将水束缚住,起到吸湿保湿作用,但是当浓度较高时甘油会吸收皮肤中水分而令皮肤有灼热感。透明质酸(HA)是由乙酰氨基葡萄糖与葡萄糖醛酸组成的双糖直链大分子酸性粘多糖,分子量在几万到几百万道尔顿之间,HA分子中存在大量-OH,使它产生强的亲水性,能够结合大量的水表现出很好的保湿性能;透明质酸的制备方法主要有组织提取法和微生物发酵法,组织提取法是制备透明质酸的传统方法,但由于受到材料的限制、提取率低、成本高等缘故,故逐渐被微生物发酵法所取代,微生物发酵法虽然工艺简单、得率高,但是分离纯化比较困难、会有免疫原性,实际应用中会引起患者不适。为此,人们不断研究开发与其结构或作用相似的产品。
蚕吐出的丝胶是一种对人体具有一系列特殊保护功能且性能优良的天然水溶性动物蛋白质,能迅速、完全溶于水,形成黏稠、微乳溶液,丝胶蛋白肽质的配伍性强,相容性好,几乎可以添加到任何含水的化妆品基质中,具独特的皮肤保湿、营养、抗衰老、稳定乳化、抗 菌消炎、促进伤口愈合及药物载体等特殊功能,改变丝胶溶液的浓度、pH、温度等可得到具有不同性能的丝胶,丝胶原液在白然条件下放置,还可以得到可逆性的各种丝胶凝胶,是一种在日化、医药、生化与保健食品等领域内用途极为广泛、性能优良的功能性蛋白质。由于丝胶分子中的氨基酸与人体皮肤中的氨基酸组成结构相似,它与皮肤具有极佳的亲和性,素有“第二皮肤”之美誉,其渗透性能好,易被皮肤吸收,是现代保湿剂中的营养佳品。然而,由于由丝胶蛋白肽制备保湿液时,一般是将少量丝胶蛋白肽溶于大量去离子水或弱酸性水中的,由于普通水或弱酸性水不易被机体吸收,因而导致分散在其中的少量的丝胶蛋白肽难以被充分吸收,保湿液的保湿效果仍有待于提高。
因此,研究一种保湿效果优异的保湿液具有十分重要的意义。
发明内容
本发明的目的是解决现有技术中保湿液保湿效果不够好的问题,提供一种弱碱性水溶解的蛋白肽保湿液及其制备方法。
为达到上述目的,本发明采用的方案如下:
一种弱碱性水溶解的蛋白肽保湿液,主要由弱碱性水、丝胶蛋白肽和胶原蛋白肽组成,弱碱性水是通过将普通自来水经净化装置处理后,用隔膜电解法活化处理得到的,净化装置中含两个滤芯,分别为活性炭滤芯和超滤膜滤芯,隔膜电解技术是把电渗透技术和电解技术结合在一起的具有综合功能特性的技术,它广泛地应用在化工、环保、有色冶金等领域,由于它充分利用两电极之反应,并将阳极区和阴极区的反应物和产物分开的功能和优点,在环保领域中能将废水、废渣、废液进行净化处理,并回收金属、酸碱等有用物质,因而越来越受到人们的重视。
本发明先利用净化装置对普通自来水进行净化处理,净化装置中含两个滤芯,分别为活性炭滤芯和超滤膜滤芯,其在除杂的同时能保留水中原有离子如Cl -、SO 4 2-、OH -,用隔膜电解法活化处理时,水中原有离子如Cl -、SO 4 2-、OH -在电场作用下的定向迁移并在阳极室发生一系列氧化反应,阴极室出水(含有OH -)为碱性水,原水中部分金属离子在阴极经电解还原而去除;
弱碱性水具有较强的渗透力、扩散力、溶解力和代谢力,容易通过细胞内外水的交换,清除自由基、有害酸性代谢物和各种废物,促进细胞的生长发育,保持细胞的生命活力;本发明的弱碱性水为小分子活性水,颗粒小、运动速度快、渗透力更强,这些活性的水进入人体和细胞的每个角落,不断激活细胞,使细胞内外都充满干净的、有活力的、营养丰富的液体,并能更多地携带对人体有益的养分、矿物质和氧气,这样就能大大促进细胞的生长、发 育,使人体细胞更具活力,能快速进入人体细胞,使细胞拥有充足的洁净水,并使细胞内外的水分达到平衡状态,新陈代谢正常进行;
丝胶蛋白肽中含有许多极性氨基酸,它们富有-OH、-COOH、-NH 2等亲水基团,丝胶蛋白肽分子在水溶液中发生高度伸展和相互缠绕,并通过氢键与水分子紧密结合,形成连续网状结构的水凝胶,具有较高的吸水和持水性能,能吸收和保持其自身质量上千倍的水分,将丝胶蛋白肽水凝胶涂布于皮肤表面后,能在其表面形成一层水化膜,使角质层水合软化,使皮肤中保持适当水分,从而让皮肤光滑、柔软、富有弹性,另外,丝胶具有与天然保湿因子相似的成份与功能,可减缓水分蒸发,保持水分长时间不易流失;
胶原蛋白肽分子的表面也有许许多多的氨基、羧基等极性侧基,当由弱碱性水、丝胶蛋白肽和胶原蛋白肽制备保湿液时,丝胶蛋白肽和胶原蛋白肽分子中的这些极性基团通过氢键、离子键与水分子相互交错结合,构成了一种三维网状结构,从而形成了一层水分子膜,形成细胞外“储水库”,可吸收30%~35%的水,从而使得保湿液具有了更好的保湿效率,同时,由于弱碱性水容易被机体吸收,导致分散在其中的蛋白肽容易被充分吸收,因而显著提高了保湿液的保湿效果。
作为优选的方案:
如上所述的一种弱碱性水溶解的蛋白肽保湿液,隔膜电解法活化处理时,两极间的电解电压为10~40V,极板间距为10~30mm,电解时间为1~5min。目前对于弱碱性电解还原水制备工艺条件的研究,多以NaCl溶液作为电解质开展,而在实际的家庭使用中,原水一般为经净化的自来水,通常不会额外添加其他物质。因此发明即以净化后的自来水为原水,通过单因素试验研究电解电压、电解时间、极板间距对出水水质的影响,以初步确定适宜的实际操作条件范围。
如上所述的一种弱碱性水溶解的蛋白肽保湿液,弱碱性水溶解的蛋白肽保湿液中弱碱性水、丝胶蛋白肽和胶原蛋白肽的质量比为450~550:3~6:2~4。
如上所述的一种弱碱性水溶解的蛋白肽保湿液,弱碱性水溶解的蛋白肽保湿液的保湿率为80~90%;
保湿率计算公式如下:
保湿率(%)=(M 0-M 1)/M 1×100%;
式中M 0为样品的初始质量(g),M 1为在25℃温度条件下放置24h后的样品质量(g)。
本发明还提供了制备如上任一项所述的一种弱碱性水溶解的蛋白肽保湿液的方法,将丝胶蛋白肽和胶原蛋白肽溶解于弱碱性水中制得弱碱性水溶解的蛋白肽保湿液。
作为优选的方案:
如上所述的方法,溶解时伴以搅拌,搅拌速率为100~300rpm,搅拌时间为10~30min。
有益效果:
(1)本发明的一种弱碱性水溶解的蛋白肽保湿液的制备方法,快速简便,适用于规模化生产;
(2)本发明的一种弱碱性水溶解的蛋白肽保湿液的制备方法,使用的丝胶蛋白肽无毒,副作用少,且可利用丝胶废弃液得到,成本较低;
(3)本发明制备的一种弱碱性水溶解的蛋白肽保湿液,具有较好的保湿效果,在化妆品行业有着广阔的应用前景。

实施例1
一种弱碱性水溶解的蛋白肽保湿液的制备方法,将丝胶蛋白肽和胶原蛋白肽溶解于弱碱性水中,弱碱性水、丝胶蛋白肽和胶原蛋白肽的质量比为500:5:3,溶解时伴以搅拌,搅拌速率为100rpm,搅拌时间为30min;
其中,弱碱性水是通过将普通自来水经净化装置处理后,用隔膜电解法活化处理得到的,如图1所示,净化装置中含两个滤芯,分别为活性炭滤芯和超滤膜滤芯,具体为:先利用净化装置对普通自来水进行净化处理,净化装置中含两个滤芯,分别为活性炭滤芯和超滤膜滤芯,再用隔膜电解法活化处理,依靠自来水中原有离子如Cl -、SO 4 2-、OH -在电场作用下定向迁移并在阳极室发生一系列氧化反应;阴极室出水(含有OH -)为碱性水,阳极室出水(含有H +)为酸性水,两极间的电解电压为36V,极板间距为10mm,电解时间为1min。
最终制得的一种弱碱性水溶解的蛋白肽保湿液的保湿率为83.6%,保湿率计算公式如下:
保湿率(%)=(M 0-M 1)/M 1×100%;
式中M 0为样品的初始质量(g),M 1为在25℃温度条件下放置24h后的样品质量(g)。
动物试验可以用来验证化妆品、药物、纳米材料等是否会引发机体过敏反应。但近年来,动物试验受到伦理性的质疑,寻找一种新的替代途径去验证测试样品的生物安全性显得尤为重要。鸡胚绒毛膜尿囊膜(CAM)是鸡胚的呼吸系统,紧贴蛋壳生长,血管丰富,由于CAM模型与兔眼粘膜结果的一致性和以及伦理上的人性化,CAM越来越多的被用于刺激性实验。
为验证本发明的弱碱性保湿水的刺激性和过敏性,本发明采用鸡胚绒毛膜尿囊膜(CAM)模型进行,具体步骤如下:
(1)种蛋的孵化
通过暗室灯照,筛选发育正常的种蛋50枚(蛋足量,避免后期鸡胚死亡等耽误实验进度),用体积浓度为75%酒精消毒,并做好编号,晾干后放入37℃孵化器中,尖端朝下,将一定量的无菌水放置于种蛋孵化机中,保持相对湿度在40%~60%,每24小时转蛋两次;
(2)CAM制作
1)选蛋:种蛋孵化十天后,去掉未受精蛋、死胚,以及其它不合格的鸡胚,取出合格发育的种蛋,用体积浓度为75%酒精消毒,超净工作台中吹风机吹干。
2)打孔:找到种蛋的气室,利用手动钻孔机打孔,用镊子去掉气室的蛋壳,并用吸耳球吹干净,在气室内滴到一定量的生理盐水(质量浓度为0.90%氯化钠水溶液),待蛋膜完全浸润后倒掉。
3)受试区的选择:用镊子去掉气室的蛋膜,并确保不破坏内粘膜的完整性,去完膜后,寻找毛细血管较丰富的地方,放置聚四氟乙烯特氟龙环,并拍照留底。
(3)刺激性实验
准备二组受试样品,分别为:去离子水溶解的蛋白肽和弱碱性水溶解的蛋白肽,超净工作台中紫外灯照射三十分钟,取出,放入步骤(2)制备好的CAM模型的聚四氟乙烯特氟龙环中,用无菌超纯水湿润过的保鲜膜封住气室,将种蛋放入恒温恒湿孵化箱中,开始计时,时长为1h。然后取出观察鸡胚血管及溶血情况,见图2,CAM的毛细血管生长状况正常,血管无明显抑制或者增殖、出血或者溶血的情况,这可以充分说明本发明的弱碱性水溶解蛋白肽对CAM血管的发育没有明显的抑制或者增殖现象,从而证实无刺激性和过敏性。
为验证本发明的弱碱性保湿水的渗透能力,特测定蛋白肽体外透皮吸收性能,包括如下步骤:
(1)离体鼠皮制备:实验用小鼠6只(体重20~22g),雌雄各半,处死,除去腹部毛发,然后剥离去毛发部位皮肤,除去脂肪和筋络,用蒸馏水反复冲洗,鼠皮洗净后用生理盐水冲 洗,再用质量浓度为10%甘油液处理,防止贮存时形成冰晶,并置于-20℃的低温冰箱中贮存备用(7d内用完);
(2)透皮实验装置:实验装置中,扩散池有效扩散面积2.0cm 2,接受池体积14mL,定制搅拌子长度1.4cm,接受液为质量浓度为0.9%的NaCl溶液;
(3)样品液制备:取出贮备鼠皮,解冻,生理盐水洗净,将其夹在接受室与供给室之间,贴药面朝向供给室,皮肤面朝向接受室,调整水浴系统温度为37.5℃,搅拌速度为100r/min,在接受室中加人预温37℃的质量浓度为0.9%NaCl溶液,排尽气泡,为降低干扰,在不含肽的情况下,先将鼠皮内层表面与接受液接触,更换全部接受液,再将本发明的弱碱性水溶解的蛋白肽保湿液注入供给室紧贴于鼠皮肤上,分别于第1h、2h、4h、6h、8h、12h、24h用注射器吸取全部接受液作为样品液,以进行蛋白肽透皮量的测定,同时,将接受室补满等温新鲜质量浓度为0.9%NaCl溶液,以保持漏槽状态,最后,将收集的7个时间段的样品液进行脯氨酸含量测定;
(4)蛋白肽含量测定:脯氨酸是胶原蛋白肽和丝胶蛋白肽的一种特性氨基酸,通过测定脯氨酸的含量来确定蛋白肽的体外透皮量,具体过程为:取6支试管,分别加入不同浓度的标准脯氨酸溶液,混匀后沸水水浴5min,冷却后,在515nm波长下测定吸光度,以吸光度为横坐标,以脯氨酸含量(μg)为纵坐标,绘出标准曲线;取步骤(3)中不同时间段获得的蛋白肽溶液5ml、冰醋酸2mL、茚三酮2mL,充分溶解混合,沸水水浴加热10min,冷却,在515nm波长下测定吸光度,根据标准曲线得到脯氨酸的含量;
(5)累积渗透量的测定,采用如下的累积渗透量公式,计算Q值:
Q=(C 1+C 2+…+C n)×V/A;
式中,Q为t时间的累积渗透量(μg/cm 2),C n为第n个取样点的浓度(μg/μL),A为渗透面积(本实验中仪器释放面积为2.0cm 2),V为接受液的总体积(14mL),结果见表1:

由表1可见,相比于去离子水,采用弱碱性水配制的保湿液,蛋白肽(胶原蛋白肽和丝胶蛋白肽)的体外透皮性能明显优于去离子水配制的蛋白肽保湿液,这是由于弱碱性水具有更好的分子活性,渗透力更强。
现有技术一般认为弱碱性水会对皮肤产生一定的刺激,因而保湿液中多采用去离子水或 弱酸性水,未见弱碱性水用于保湿液的报道,本发明制得的弱碱性水不仅温和,不会对皮肤产生刺激,且渗透性较高,有利于皮肤充分吸收蛋白肽,长效保湿锁水。
对比例1
一种弱酸性水溶解的蛋白肽保湿液,其制备方法基本与实施例1相同,不同之处在于用弱酸性水替代弱碱性水,弱酸性水是通过本发明的装置的阳极室出水制得的,最终制得的一种弱酸性水溶解的蛋白肽保湿液的保湿率为65.2%。
将实施例1与对比例1进行对比可以看出,实施例1制得的一种弱碱性水溶解的蛋白肽保湿液的保湿效率更高,这是因为在生命长期的进化过程中,人体形成了较为稳定的呈微碱性的内环境,正常人血液pH(酸碱度)应在7.4左右(7.35-7.45),这种pH的恒定现象,叫做酸碱平衡,弱碱性水和人体内环境酸碱度更为接近,模拟了人体内环境,从而具有更好的保湿率。
对比例2
一种去离子水溶解的蛋白肽保湿液,其制备方法基本与实施例1相同,不同之处在于用去离子水替代弱碱性水,最终制得的一种去离子水溶解的蛋白肽保湿液的保湿率为42.3%。
将实施例1与对比例2进行对比可以看出,实施例1制得的一种弱碱性水溶解的蛋白肽保湿液的保湿效率更高,这是因为弱碱性水的水分子团由5~6个水分子组成,即电场处理后水分子团簇结构变小,而一般自来水由13个分子团组成。弱碱性水且其所呈现的六元环型结构与人体组织内水的结构相似,因此弱碱性水具有更高的生物膜透过率,极易进出于细胞膜内外,有利于蛋白肽在细胞内外的交换,提高其保湿效率。
实施例1、对比例1和对比例2的对比结果如图3所示,对比可以看出弱碱性水溶解的蛋白肽的保湿效率明显高于弱酸性水和去离子水。
对比例3
一种弱碱性水溶解的蛋白肽保湿液,其制备方法与实施例1基本相同,不同之处在于仅将丝胶蛋白肽溶解在弱碱性水中,丝胶蛋白肽与弱碱性水的质量比为8:500,最终制得的一种弱碱性水溶解的蛋白肽保湿液的保湿率为72.8%。
将实施例1与对比例3进行对比可以看出,实施例1制得的一种弱碱性水溶解的蛋白肽保湿液的保湿效率更高,这是因为丝胶蛋白肽含有丰富的极性氨基酸和功能基团,胶原蛋白肽分子的表面也有许许多多的氨基、羧基等极性侧基,丝胶蛋白肽和胶原蛋白肽分子中的这些极性基团通过氢键、离子键与水分子相互交错结合,构成了一种三维网状结构,从而形成了一层水分子膜,形成细胞外“储水库”,可吸收30%~35%的水,从而具有了更好的保湿效率。
对比例4
一种弱碱性水溶解的胶原蛋白肽保湿液,其制备方法与实施例1基本相同,不同之处在于仅将胶原蛋白肽溶解在弱碱性水中,胶原蛋白肽与弱碱性水的质量比为8:500,最终制得的一种弱碱性水溶解的胶原蛋白肽保湿液的保湿率为59.6%。
将实施例1与对比例4进行对比可以看出,实施例1制得的一种弱碱性水溶解的蛋白肽保湿液的保湿效率更高,这是因为丝胶蛋白肽含有丰富的极性氨基酸和功能基团,胶原蛋白肽分子的表面也有许许多多的氨基、羧基等极性侧基,丝胶蛋白肽和胶原蛋白肽分子中的这些极性基团通过氢键、离子键与水分子相互交错结合,构成了一种三维网状结构,从而形成了一层水分子膜,形成细胞外“储水库”,可吸收30%~35%的水,从而具有了更好的保湿效率。
对比例5
一种弱碱性水溶解的透明质酸保湿液,其制备方法与实施例1基本相同,不同之处在于将透明质酸溶解在弱碱性水中,透明质酸与弱碱性水的质量比为8:500,最终制得的一种弱碱性水溶解的透明质酸保湿液的保湿率为33.6%。
将实施例1与对比例5进行对比可以看出,实施例1制得的一种弱碱性水溶解的蛋白肽保湿液的保湿效率更高,这是因为丝胶蛋白肽含有丰富的极性氨基酸和功能基团,胶原蛋白肽分子的表面也有许许多多的氨基、羧基等极性侧基,丝胶蛋白肽和胶原蛋白肽分子中的这些极性基团通过氢键、离子键与水分子相互交错结合,构成了一种三维网状结构,从而形成了一层水分子膜,形成细胞外“储水库”,可吸收30%~35%的水,从而具有了更好的保湿效率。
对比例6
一种弱碱性水溶解的甘油保湿液,其制备方法与实施例1基本相同,不同之处在于用甘油去溶解弱碱性水,甘油与弱碱性水的质量比为8:500,最终制得的一种弱碱性水溶解的甘油保湿液的保湿率为84.1%。
将实施例1与对比例6进行对比可以看出,对比例6制得的一种弱碱性水溶解的蛋白肽保湿液的保湿效率与实施例1相近,但是当甘油浓度较高时会吸收皮肤中水分而令皮肤有灼热感,实际体验较差;
实施例1、对比例3~6的对比结果如图4所示,对比可以看出弱碱性水溶解的混合蛋白肽(丝胶蛋白肽和胶原蛋白肽)的保湿效率接近弱碱性水溶解的甘油,明显高于弱碱性水溶解的其他物质,这是因为丝胶蛋白肽和胶原蛋白肽相互之间能够产生一定的协同作用,有利于提高保湿液的保湿效果。
实施例2
一种弱碱性水溶解的蛋白肽保湿液的制备方法,基本同实施例1,不同之处在于,弱碱性水、丝胶蛋白肽和胶原蛋白肽的质量比为450:3:2,搅拌速率为150rpm,搅拌时间为26min,两极间的电解电压为10V,极板间距为15mm,电解时间为3min。最终制得的一种弱碱性水溶解的蛋白肽保湿液的保湿率为80%。
实施例3
