Description

一种含泛醇组合物以及护肤品
技术领域
本发明涉及A61Q技术领域,更具体地,本发明涉及一种含泛醇组合物以及护肤品。
背景技术
维生素B5,即泛酸,是一种水溶性维生素,通过转化为辅酶A,参与人体代谢循环,泛醇即维生素原B5,相比于泛酸,更容易被机体吸收,能够对角质层做到有效的渗透作用,保湿效果优异,同时可以刺激皮肤表皮细胞的生长,加速创口的愈合,适用干性皮肤、油性皮肤、紧致皮肤、皱纹皮肤、敏感皮肤等多种肌肤,在护肤品中广泛应用。
然而泛醇极其容易水解,降低了护肤品的功效性,且目前尚未解决泛醇水解的问题,例如CN202010531035通过多种植物提取物、泛醇、甘油、丁二醇等得到一种祛皱修护的护肤品,该护肤品具有一定的抗衰效果,然而一段时间后通过测定该护肤品,其中的泛醇含量显著降低,使得随着时间的延长,该护肤品的功效性降低。CN202110415938提供了一种组合物,包括肌肽、泛醇、琥珀等,随着时间的延长,测定得到的该组合物中泛醇的含量同样显著降低。
发明内容
针对现有技术中存在的一些问题,本发明第一个方面提供了一种含泛醇组合物,包括泛醇、氢离子缓冲成分、琥珀酸二乙氧基乙酯、芦丁衍生物。
优选的,所述含泛醇组合物还包括杀菌剂。
在一种实施方式中,按重量份计,含泛醇组合物包括3-8份泛醇、0.5-5份氢离子缓冲成分、0.5-2份琥珀酸二乙氧基乙酯、0.05-0.15份芦丁衍生物。优选的,按重量份计,含泛醇组合物包括3-8份泛醇、0.5-1.5份氢离子缓冲成分、0.5-1份琥珀酸二乙氧基乙酯、0.05-0.15份芦丁衍生物。更优选的,按重量份计,含泛醇组合物包括5份泛醇、1份氢离子缓冲成分、1份琥珀酸二乙氧基乙酯、0.1份芦丁衍生物、0.1-0.2份杀菌剂。
优选的,所述氢离子缓冲成分含有羟基和/或磺酸基团。
优选的,所述氢离子缓冲成分为4-羟乙基哌嗪乙磺酸。
优选的,所述芦丁衍生物选自芦丁羟乙基醚衍生物、芦丁羧甲基衍生物、葡糖基芦丁中一种或多种。
优选的,所述芦丁羟乙基醚衍生物为曲克芦丁。
在一种实施方式中,芦丁衍生物为曲克芦丁和/或葡糖基芦丁。
本发明第二个方面提供了一种含有该泛醇组合物的护肤品。
本申请中护肤品的种类本领域技术人员可以常规选择,例如精华水、保湿水、精华液、面膜、面霜等。
在一种实施方式中,按重量份计,所述护肤品包括1-15份含泛醇组合物、0.3-1份增稠剂、1-15份保湿剂、0-1份防腐剂,去离子水补足100份。优选的,按重量份计,所述护肤品包括7-12份含泛醇组合物、0.3-0.5份增稠剂、6-8份保湿剂、0-1份防腐剂,去离子水补足100份。
本申请所述增稠剂不作特别限定,本领域技术人员可作常规选择,可以列举的有汉生胶、卡波姆、AVC增稠剂等,优选为AVC增稠剂。
本申请中防腐剂不作特别限定,优选的,防腐剂为己二醇和/或戊二醇,进一步优选的,所述己二醇和戊二醇的重量比为1:(0.5-2),更优选重量比为1:1。
在一种实施方式中,所述保湿剂选自甘油、海藻糖、透明质酸钠类物质、甘油葡糖苷、尿素中一种或多种。
优选的,所述甘油、海藻糖、透明质酸钠类物质、甘油葡糖苷、尿素的重量比为(30-35):(3-5):1:(1-10):(0.5-5),更优选为33.3:3.3:1:6.6:1.3。
优选的,所述透明质酸钠类物质包括乙酰化透明质酸钠和水解透明质酸钠,进一步优选的,二者重量比为1:(1-3),更优选为1:2。
本申请中护肤品的制备方法为本领域技术人员所熟知的常规方法。
本申请中CPN为氯苯甘醚,HEPES为4-羟乙基哌嗪乙磺酸,DES为琥珀酸二乙氧基乙酯。
本发明与现有技术相比具有以下有益效果:
(1)本申请中4-羟乙基哌嗪乙磺酸,尤其与琥珀酸二乙氧基乙酯复配后有效缓解了泛醇的水解,可以长效保持泛醇的含量,提高护肤品的有效性,同时可以和泛醇相互协调,促进泛醇对角质层的浸润。
(2)芦丁衍生物的添加,尤其是芦丁衍生物为曲克芦丁、葡糖基芦丁时,不仅进一步缓解了泛醇水解,使得8个月后仍维持90%泛醇含量,相比于现有技术中半年泛醇就高达50%的水解率,具有显著的优势。
(3)本申请护肤品中使用含量为0.3-0.5重量的AVC增稠剂,结合本申请中保湿剂成分和含量,护肤剂在制备过程中相融性好,使得具有良好的加工性,在较短的时间内即可搅拌均匀,大大提高了生产效率。
(4)本申请中特定含量的甘油、海藻糖、透明质酸钠类物质、甘油葡糖苷、尿素、AVC增稠剂和本申请中含泛醇组合物能够相互协调,不仅提供了较好的肤感,促进肌肤的通透性,赋予皮肤较好的弹性,同时具有优异的保水能力。
(5)该护肤品通过各个物质的调控,放置一段时间后也具有很好的稳定性,且能够抵抗高低温环境。
