Description
技术领域
本发明公开了一种精华液及其制备方法,具体地说,是一种三层保湿精华液,属于化妆品技术领域。
背景技术
常用的基础护肤产品主要包括O/W乳液(或膏霜)、W/O乳液(或膏霜)、精华、防晒、粉底、啫喱、水剂等。现有的精华液产品大部分为粘度低、流动性好的水状或略稠妆的液体产品,剂型以单一剂型为主,外观比较单一,保湿效果相对于乳液较差。乳液由于添加较多的润肤剂成分,粘度较大,在使用感和触感方面会变差。
目前,市面常见的精华液产品为单层型和双层型。双层型的精华液兼具水状和乳状两种状态,使用前需要将上下层摇匀。已有的双层型的精华产品主要是运用油水不相容和比重的区别达到分层的目的,虽然外观上达到了两层的状态,但是使用静置后并不能形成较好的分层外观,即水相层在较长时间不能恢复至透明状态,产品稳定性欠佳。另外有些产品分层速度太快,需要多次摇匀使用,在使用便利性方面有待改善。
市面上精华液产品种类繁多,除了好的肤感体验、优异的功效作用外,独特的外观也慢慢成为吸引消费者购买的原因之一。因此,开发一种外观新颖、分层效果好、滋润而又不粘腻并且保湿效果佳的精华液产品非常有必要。
发明内容
本发明的目的是提供一款具有特殊外观的精华液,该精华液为三层(上层为油溶性润肤剂,中层为水溶性保湿剂,下层为特殊溶解性的皮肤调理剂)保湿精华液,该精华液静止时上层为透明乳液,中层为透明水状,下层为透明乳状,三层均为透明外观,使用前轻轻摇动即可混为一体,带来独特的视觉效果和肤感体验,该精华液同时具有化妆水和乳液的使用感,粘度低、水润感强,保湿效果好。精华液在摇匀使用后能够快速分层,界面清晰,外观漂亮。
为此,本发明提供的第一个技术方案是这样的:
一种三层保湿精华液,包括水和以下重量份的组分:
润肤剂20-40重量份;
保湿剂5-10重量份;
皮肤调理剂0.5-25重量份;
抗氧化剂0.1-0.3重量份;
收敛剂2-3.5重量份;
着色剂0.00001-0.0001重量份。
为了提升该三层保湿精华液的肤感体验,本发明提供的精华液中的组分均不会对肌肤产生刺激。
其中,润肤剂包括油性溶剂和植物油,油性溶剂包括环五聚二甲基硅氧烷、聚二甲基硅氧烷、聚二甲基硅氧烷醇和辛酸/癸酸甘油三酯,油性溶剂的组合能让精华液清爽丝滑,植物油包括霍霍巴(SIMMONDSIA CHINENSIS)籽油和澳洲坚果(MACADAMIA TERNIFOLIA)籽油,植物油的组合渗透性好,有很好的保湿和滋润肌肤的作用。油性溶剂和植物油的结合能够进一步提高精华液在摇匀使用后的分层速度,能够较快形成上层的透明乳液同时中层和下层能够保持较好的透明状态。,同时油性溶剂和植物油的结合能使得精华液具有较好的产品稳定性。优选的,油性溶剂和植物油的质量比为2-4:1。
其中,保湿剂包括甘油、1,3-丙二醇、海藻糖、甜菜碱和赤藓醇。
其中,皮肤调理剂包括烟酰胺、泛醇、琥珀酸二乙氧基乙酯、氯化钠、柠檬酸钠和柠檬酸。琥珀酸二乙氧基乙酯的质量为皮肤调理剂总质量的70-80%。在一实施例中,为了使该精华液具有更多的护肤功效,本发明中还添加了玫瑰花水、酵母精华提取物、假叶树根提取物、积雪草叶提取物、金盏花花提取物、麦冬根提取物、扭刺仙人掌茎提取物、苦参根提取物中的一种或几种组合作为皮肤调理剂。
其中,抗氧化剂选自对羟基苯乙酮、1,2-己二醇、1,2-戊二醇、辛酰羟肟酸、乙基己基甘油中任意一种或组合。优选的,抗氧化剂为对羟基苯乙酮。
其中,收敛剂为乙醇。
其中,着色剂为蓝色水溶色素CI 42090。
在本发明的技术方案中,为了进一步提升精华液的使用体验,精华液还可以包括0.01-0.1重量份的香精。
本发明提供的第二个技术方案是这样的:
上述三层保湿精华液的制备方法,主要包括如下步骤:
步骤一,将水、保湿剂、皮肤调理剂加入乳化锅,搅拌状态下加热至80-90℃,混合均匀后降温至30-32℃;
步骤二,将润肤剂加入乳化锅中,均质2-10min;
步骤三,将抗氧化剂预先用水溶解后再加入乳化锅中,搅拌至混合均匀;
步骤四,将收敛剂和着色剂加入乳化锅中,搅拌至混合均匀;
步骤五,取样检测,合格后用双层300目或双层400目滤布过滤出料。
本发明提供的精华液静止时上层为透明乳液,中层为透明水状,下层为透明乳状,摇匀使用时为相容性好的透明乳液。该三层精华液使用时不粘腻,具有水润质感,保湿效果好,体系稳定。
与现有技术相比,本发明提供的技术方案至少具有如下技术优点:
1.本发明提供的三层保湿精华液,由于添加了蓝色水溶色素CI 42090作为着色剂,因此三层分界线明显,具有漂亮的外观。该精华液轻轻摇动即可混合均匀。该精华液在摇匀使用后能够速度分层,静置约五分钟可分为两层,静置约十分钟即可分为三层;
2.本发明提供的三层保湿精华液通过润肤剂、保湿剂、皮肤调理剂等组分的合理组配,整个精华液在使用时粘度低,具有较好的水润感,使用体验感优异。同时由于精华液中还添加了皮肤调理剂,使得配方具有较好的抗敏舒缓功效,在保湿的同时能有效缓解外界的过敏刺激,保持肌肤水润健康;
3.本发明提供的三层保湿精华液中,保湿剂包括甘油、1,3-丙二醇、海藻糖、甜菜碱和赤藓醇,保湿剂复配后具有优异的保湿效果,同时兼具柔软、润滑且不粘腻的肤感。使用后能够给肌肤提供滋润度及持久的保湿能力,赋予皮肤柔软光滑的质感;
4.本发明提供的三层保湿精华液的上层液体包括润肤剂、中层液体包括水、保湿剂以及部分皮肤调理剂(烟酰胺、泛醇、氯化钠、柠檬酸钠、柠檬酸和部分的琥珀酸二乙氧基乙酯),下层液体包括琥珀酸二乙氧基乙酯;琥珀酸二乙氧基乙酯具有轻盈清爽的肤感并且有保湿滋润的作用,琥珀酸二乙氧基乙酯在水中可以部分溶解,但不溶于润肤剂的油性溶剂/植物油中,从而实现精华液的三层外观,更具体的,为了实现精华液的三层外观需要同时满足:①润肤剂的组分复配需要在满足水润清爽的肤感和滋润肌肤的效果的情况下,与琥珀酸二乙氧基乙酯不相容;②精华液的水溶性组分均匀的溶解在水中形成混合液,水溶性组分的复配在满足精华液的使用效果的情况下尽可能降低琥珀酸二乙氧基乙酯在所述混合液中的溶解性;③为了增加分层速度,精华液中通过添加氯化钠、柠檬酸和柠檬酸钠产生盐析作用加快中层液体和上层液体的油水两相分离、以及中层液体和下层液体的分离;
5.本发明提供的三层保湿精华液中的皮肤调理剂包括泛醇,泛醇能够减少经皮水分散失,修复皮肤屏障,减少炎症因子的释放,舒缓炎症肌肤,减轻肌肤泛红,促进成纤维细胞的增值和迁移,有效加速伤口愈合;
6.本发明提供的三层保湿精华液中的皮肤调理剂包括烟酰胺,烟酰胺可以抑制黑色素的转移,也有很好的控油效果;
7.本发明提供的三层保湿精华液中,保湿剂包括海藻糖、甜菜碱和赤藓醇,海藻糖、甜菜碱和赤藓醇的组合能够有效保留住肌肤水分,还有利于皮肤表面有益菌的生存。
下面结合具体实施例进行说明。
具体实施方式
应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
实施例1、对比例1-4提供的三层保湿精华液的具体组分配比如表1所示。
实施例1、对比例1-4提供的三层保湿精华液的制备方法均包括如下步骤:
步骤一,将水、保湿剂、皮肤调理剂加入乳化锅,搅拌状态下加热至80-90℃,混合均匀后降温至30-32℃;
步骤二,将润肤剂加入乳化锅中,均质2-10min;
步骤三,将抗氧化剂预先用水溶解后再加入乳化锅中,搅拌至混合均匀;
步骤四,将收敛剂和着色剂加入乳化锅中,搅拌至混合均匀;
步骤五,取样检测,合格后用双层300目或双层400目滤布过滤出料。
表1实施例1、对比例1-4提供的三层保湿精华液的具体组分配比
对实施例1提供的三层保湿精华液进行如下测试:
1.即时保湿效果测评
将精华液按(2.0±0.1)mg/cm2的用量在前臂内侧进行单次涂布,均匀涂抹测试区域内,然后采用皮肤水分测试仪(德国CKCorneometer CM825)在使用前、15min、45min、1h、2h测试左右前臂内侧测试区域的皮肤含水量,具体结果如表2所示。
表2受试者在不同的时间点前臂内侧角质层水分含量(x±s)
皮肤水分测定仪(德国CKCorneometer CM825)用于检测皮肤角质层水分含量,皮肤角质层水分含量测量值越高,说明皮肤角质层水分含量越高,使用精华液在30min、45min、1h、2h的面部皮肤含水量与使用前测试值比较,均具有统计学意义(P<0.05)。从表2可以看出,受试者在涂抹实施例1提供的的精华液以后,皮肤含水量有了较大的提高,并且在使用2h后,仍然具有一定的保湿效果。
2.减少经皮水分散失
将精华液摇匀,然后取3滴于掌心,分别涂抹于受试者左右脸颊,早晚两次,持续4周,同时采用经皮水分流失测试探头(德国CKTewameter TM Hex)检测左右脸颊颧骨皮肤在使用前、使用2周、使用4周的经皮水分流失率(TEWL)如表3所示。使用精华液在D14、D28的面部皮肤TEWL值与使用前测试值比较,均具有统计学意义(P<0.05)。
表3受试者在不同的时间点面部测试区域TEWL值的变化
为了更好地证明本发明的技术效果,本申请针对实施例1和对比例1-4分别进行了稳定性、分层速度、下层液体清澈速度、保湿功效的相关测试。
1.稳定性测试
1)测试样品:实施例1提供的精华液、对比例1-4提供的精华液。
2)测试方法:每个测试样品分别设置5组实验,分别进行耐热(45℃)、耐寒(-15℃)、寒热交叉(-15℃/45℃)、常温、光照条件下的稳定性测试1个月,观察各组样品是否分层、下层液体是否变浊等不稳定现象出现。
3)测试结果:
实施例1制得的精华液经过1个月的测试,在高温、低温、寒热交替、常温、光照条件下均能够保持三层液体为清澈透明的稳定状态,未出现产品变黄、下层变浑浊等不稳定现象,说明本发明提供的精华液体系稳定。
对比例1-4在常温下放置一段时间后,开始出现上层的乳液沉降,导致界面不清晰,中层液体和下层液体变浑浊的现象,产品不稳定。
经过稳定性测试发现,本发明提供的精华液中润肤剂/保湿剂的组分缺失对于状态稳定会产生负面影响。
2.分层速度测试以及下层液体清澈速度测试
1)测试样品:实施例1提供的精华液、对比例1-4提供的精华液。
2)测试方法:将实施例1、对比例1-4的精华液分别放入30ml透明PE材质的样品瓶中,轻轻摇匀使三层液体完全混合,静置放置,记录精华液开始分层所需要的时间、分为三层所需要的时间以及三层液体均变成完全透明所需要的时间,测试时间1小时。前半个小时,每1分钟观察一次;半个小时至1个小时,每5分钟观察一次。
3)测试结果如表4所示。
表4分层效果测试
样品 | 开始分层时间(min) | 分为三层时间(min) | 三层液体均变清澈透明时间(min) |
实施例1 | 5 | 11 | 12 |
对比例1 | 25 | 30 | 42 |
对比例2 | 20 | 28 | 55 |
对比例3 | 5 | 15 | 26 |
对比例4 | 6 | 14 | 24 |
从表4的分层效果测试结果可以看出,实施例1提供的精华液在静置5min可分为两层,静置11min即可分为三层,该精华液静置12min三层液体均变成完全透明。从实施例1、对比例1-4中可以看出,当配方中含有特定组分和含量的润肤剂/保湿剂时,三层精华液中的三层液体变透明的时间更短,能够在摇匀使用后的较短时间内形成一种外观漂亮的三层精华液,为消费者提供较好的使用体验感。
以上所述实施例的各技术特征可以进行任意的组合,为使描述简洁,未对上述实施例中的各个技术特征所有可能的组合都进行描述,然而,只要这些技术特征的组合不存在矛盾,都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式,其描述较为具体和详细,但并不能因此而理解为对发明专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本发明构思的前提下,还可以做出若干变形和改进,这些都属于本发明的保护范围。因此,本发明专利的保护范围应以所附权利要求为准。
