Description
技术领域
本发明涉及护肤品技术领域,具体涉及一种锁水保湿面膜及其制备方法。
背景技术
面膜是一种用于皮肤补水、保湿、滋润、营养、改善外观以及深层清洁的护肤品,因此,在进行面膜配方研发和设计时,不仅仅需要考虑面膜中精华液中的活性组分的功效,面膜基布的性能和质量也是影响面膜整体效果的重要因素。
现有的贴布式面膜主要是通过在无纺布上涂附上一层凝胶制剂或直接将面膜液浸渍无纺布制成,也有用蚕丝、棉、生物纤维等其它材料制成膜布的贴布式面膜,基于以上材料制成的贴布式面膜大多都不具备锁水保湿功能,在面膜的使用过程中,附着在面膜上的面膜液极易挥发,造成面膜液有效成分减少,用户体验感变差,为维持面膜的有效使用时间,生产商需加大面膜液使用量,在一定程度上增加了生产成本。
中国专利文献(CN113208934B)公开了一种氧化石墨烯-壳聚糖面膜布及其制备方法,通过将氧化石墨烯溶液与包含壳聚糖的聚乙二醇溶液混合成膜,成孔,形成以氧化石墨烯与壳聚糖交联复合物为基底的多孔复合膜,所制备的复合膜材料的力学性能和抗菌性能虽有一定程度的提升,但氧化石墨烯与壳聚糖是采用物理共混的方式,且所添加的氧化石墨烯并不具有吸水保湿的功能,因此,面膜材料的综合性能仍需要进一步提高。
发明内容
针对现有技术的不足,本发明的目的在于提供一种锁水保湿面膜及其制备方法,解决现有的面膜材料力学性能以及锁水保湿性能不佳的技术问题。
为了实现上述目的,本发明采取如下技术方案:
一种锁水保湿面膜的制备方法,包括如下步骤:
(1)将壳聚糖加入到水杨酸溶液中,搅拌溶解,然后向其中加入氯化钠、聚乙二醇二缩水甘油醚和黄原胶溶液,搅拌混合均匀,转移至模具中,冷冻干燥,得到固体膜;
(2)将所得到的固体膜置于干燥箱中,进行固化交联反应,待反应完成后,置于水中,热处理除去氯化钠,经洗涤、干燥,得到改性壳聚糖膜;
(3)将改性壳聚糖膜浸入硝酸锌溶液中,在室温下振荡3-5h,随后用去离子水清洗未螯合的锌离子,冷冻干燥,得到面膜基布;
(4)将面膜基布浸入面膜液中,即得到锁水保湿面膜,其中面膜液包括如下原料:泊洛沙姆407、甘油、精氨酸、羟基乙酸、壬二酸、扁桃酸、乳糖酸、白柳树皮提取物、油橄榄叶提取物和水。
优选的,步骤(1)中,壳聚糖、水杨酸溶液、氯化钠、聚乙二醇二缩水甘油醚和黄原胶溶液的质量比为4-8:150-200:0.2-0.3:1-2:10-25。
优选的,步骤(1)中,水杨酸溶液的质量分数为2-3%。
优选的,步骤(1)中,黄原胶溶液的质量分数为0.5-1%。
优选的,步骤(2)中,固化交联反应的温度为60-80℃,固化交联反应的时间为4-6h。
优选的,步骤(2)中,热处理的温度为70-80℃,热处理时间为3-5h。
优选的,步骤(3)中,硝酸锌溶液的质量分数为1-3%。
优选的,步骤(4)中,面膜液包括如下重量份的原料:2-5份泊洛沙姆407、3-6份甘油、0.8-1.5份精氨酸、3-5份羟基乙酸、2-4份壬二酸、1-3份扁桃酸、2-5份乳糖酸、0.6-1.5份白柳树皮提取物、0.6-2份油橄榄叶提取物和70-80份水。
本发明还提供由上述制备方法所制备得到的锁水保湿面膜。
与现有技术相比,本发明具有如下有益效果:
(1)本发明中的面膜液采用复合酸溶液,以壳聚糖作为面膜基布时,考虑到壳聚糖具有酸溶性,本发明通过交联剂聚乙二醇二缩水甘油醚的作用,将水杨酸和黄原胶接枝在壳聚糖上,通过分子间的交联作用,提升了壳聚糖分子的空间结构稳定性,使壳聚糖的抗酸能力显著提高,同时也提高了面膜基布的力学性能。
(2)本发明提供的黄原胶是一种大分子的亲水胶体,水杨酸是一种小分子物质,通过将黄原胶和水杨酸接枝在壳聚糖上,一方面,黄原胶和水杨酸分子中含有大量的亲水基团,提升了面膜基布的吸液性能,另一方面,黄原胶与壳聚糖交联形成稳定的三维空间网络结构,而小分子水杨酸填充在三维网络结构中,形成多孔隙、多沟壑结构,通过氢键作用及孔隙、沟壑结构达到吸液保液的效果,进而提升了面膜基布的保湿能力。
(3)本发明中加入氯化钠的目的在于制备高分子膜的微米孔结构,氯化钠与高分子基体混合均匀后以微米的连续态结构维持在基体内部,再将氯化钠在热水中溶出,即得到多孔结构,进一步提升了面膜基布的吸液保液能力。
(4)本发明中的水杨酸和黄原胶能够为锌离子提供大量的吸附位点,将锌离子负载在面膜基布上,提升了面膜基布的抗菌性能,避免了面膜基布因为营养丰富而导致细菌增生。
