Description

一种控油水凝乳及其制备方法
技术领域
本发明涉及一种控油水凝乳及其制备方法,属于化妆品领域。
背景技术
皮脂腺是位于皮肤真皮层的囊状附属腺体,其细胞合成脂肪后会堆积在细胞质内,使细胞逐渐胀大最后破裂,而皮脂就是这些脂肪性物质与细胞碎片混合而成的。人体除手、脚掌外,都有皮脂腺的分布,在头皮与脸部是最密集的,尤其是在鼻子两侧、额头、发际、耳后、前胸以及上背区域,也因此才有了油性肤质和油性发质的分类。
由于皮肤腺的分泌与激素有密切的关系,尤其是雄性激素,因此青少年时段会是高峰期。皮脂的分泌也与环境温度有很大的关系,因此,夏季皮脂分泌会比较旺盛,出油情况也严重的多。皮肤的产生是在深夜时候最旺盛,产生后会先存储在皮脂腺中,到了白天皮脂腺就会逐渐将制造的皮脂分泌至皮肤表面,而中午12点到下午2点则是皮肤分泌的高峰。此外,心理的因素、油腻的食物、药物等也都会刺激诱发皮脂的分泌。
皮脂腺可以分泌皮脂,经导管进入毛囊,再经毛孔排到皮肤表面。皮脂为油状半流态混合物,含有多种脂类。主要成分为甘油三酯、脂肪酸、磷脂、脂化胆固醇等。皮脂能够形成一层膜,作为皮肤化学屏障的组成部分之一,发挥保湿等重要的生理作用。但是,油脂分泌过于旺盛,也给嗜脂性细菌、真菌、寄生虫制造了良好的生活环境,它们过度繁殖,将引发一系列皮肤问题。
现有技术中采用普通硅石作为化妆品的控油成分,普通硅石多数为非中空的粉状二氧化硅,比表面积小,在相同粒径下,普通硅石的吸油量小,控油效果不够理想。

具体实施方式
本发明提供一种控油水凝乳,以所述控油水凝乳的总重量计,包括以下组分:润肤剂、乳化剂、乳化稳定剂、增稠剂、保湿剂、pH中和剂、空心微粉和水。
根据本发明的控油水凝乳,其中,以所述控油水凝乳的总重量计,所述空心微粉的加入量为1-20%,优选为5-15%;本发明的空心微粉优选为球形多孔硅粉,其只吸油不吸水,从而达到即时控油和持久控油。本发明的球形多孔硅粉是疏水性的,使得本发明的控油水凝乳不仅能吸走油脂,而且用于皮肤上又没有厚重的感觉。一般而言,吸油量与硅粉的粒径大小、孔隙大小和分布、比表面积有关。本发明通过对二氧化硅进行改性,从而得到空间杂化的空心微粉,使其比表面积大大提高,从而提高了吸油量。
优选地,所述空心微粉包括多孔硅粉,所述多孔硅粉的粒径范围为0.1-8μm,吸油量为180-400mL/100g。当多孔硅粉的粒径范围在0.1-8μm之间时,吸油量在180-400mL/100g之间,吸油量大,并且其与控油水凝乳的其它组分进行结合时,控油水凝乳的外观更加均匀细腻,呈稀液状,肤感好。另外,如果本发明的空心微粉的加入量小于1%,无法起到控油的效果,如果空心微粉的加入量大于20%,则影响控油水凝乳的稳定性和使用肤感。
根据本发明的控油水凝乳,其中,以所述控油水凝乳的总重量计,所述润肤剂的加入量为1-10%;优选为5-9%;本发明的润肤剂具有保湿、滋润、保护的作用,并且其铺展性强、易于乳化、肤感及极性好。本发明的润肤剂还具有较好的耐热性、耐候性,与化妆品的其它组分具有很好的相容性。
本发明的润肤剂不含有与皮肤油脂成分接近的动物油脂、植物油脂、合成油脂及矿脂等,从而减少控油水凝乳中的油脂含量,间接提高控油效果。当润肤剂的加入量小于1%时,使得本发明的控油水凝乳的滋润效果不明显,当润肤剂的加入量大于10%时,肤感偏油腻,不够清爽。优选地,所述润肤剂包括聚二甲基硅氧烷、PEG-7甘油椰油酸酯、复合氨基酸中的一种或两种以上的组合。
另外,需要说明的是,本发明中的复合氨基酸,是指以人或者动物毛发,皮毛或者以豆粕,菜粕,棉粕为原料,经微生物发酵、酸碱水解处理后,喷雾干燥加工而成的复合氨基酸。一般而言,复合氨基酸含有甘氨酸、亮氨酸、蛋氨酸、酪氨酸、组氨酸、苏氨酸、丙氨酸、异亮氨酸、色氨酸、胱氨酸、赖氨酸、天门冬氨酸、缬氨酸、苯丙氨酸、脯氨酸、丝氨酸、谷氨酸、精氨酸等18种氨基酸。
根据本发明的控油水凝乳,其中,以所述控油水凝乳的总重量计,所述乳化剂的加入量为0.5-5%;优选为2-4%;本发明的乳化剂分散在分散质的表面时,形成薄膜或双电层,可使分散相带有电荷,能够阻止分散相的小液滴互相凝结,使形成的控油水凝乳比较稳定。当乳化剂的加入量小于0.5%时,乳化能力不够,容易出现破乳分层等不稳定情况;当乳化剂的加入量大于5%时,肤感厚重,不够清爽。优选地,所述乳化剂包括聚甘油-3甲基葡糖二硬脂酸酯、PEG-20甲基葡糖倍半硬脂酸酯、吐温60、鲸蜡硬脂基葡糖苷中的一种或两种以上的组合。
根据本发明的控油水凝乳,其中,以所述控油水凝乳的总重量计,乳化稳定剂的加入量为0.5-5%;优选为0.8-3%;本发明的乳化稳定剂,能够起到一定的辅助乳化作用,使乳化液滴粒径更加均匀,控油水凝乳更加细腻,同时有助于空心微粉在控油水凝乳中的均匀分散。当乳化稳定剂的加入量小于0.5%时,乳化稳定效果不明显;当乳化稳定剂的加入量大于5%时,所制备得到的控油水凝乳会粘滞粗糙。优选地,所述乳化稳定剂包括肉豆蔻醇、鲸蜡醇、硬脂醇、山嵛醇、甘油硬脂酸酯中的一种或两种以上的组合。当选用肉豆蔻醇作为乳化稳定剂时,其分子量较小,使用时更容易推开,能够进一步提高肤感。
根据本发明的控油水凝乳,其中,以所述控油水凝乳的总重量计,增稠剂的加入量为0.05-1%;优选为0.1-0.5%;本发明增稠剂能够用于提高控油水凝乳的粘稠度或形成凝胶,保持水凝乳的稳定性,改善水凝乳的物理性状。赋予水凝乳黏润性并兼有乳化、稳定或使其呈悬浮状态的作用。当增稠剂的加入量小于0.05%时,所制备得到的控油水凝乳浓度较小,乳液流动性大,影响控油水凝乳的稳定性,当增稠剂的加入量大于1%时,所制备得到的控油水凝乳的浓度过大,使用效果差。
优选地,所述增稠剂包括卡波姆、聚丙烯酰胺/C13-14异链烷烃/月桂醇醚-7(例如:牌号:Sepigel305)、丙烯酸羟乙酯/丙烯酰二甲基牛磺酸钠共聚物(例如:牌号:SepinovEMT10)、丙烯酰二甲基牛磺酸铵/VP共聚物(例如:牌号:Aristoflex AVC)中的一种或两种以上的组合。
根据本发明的控油水凝乳,其中,以所述控油水凝乳的总重量计,保湿剂的加入量为1-8%,优选为3-6%;本发明的保湿剂能够将水分锁在皮肤中,并且修补细胞间质。使得皮肤表皮层及角质层具有吸湿性,且对皮肤酸碱值具有调节功能,亲肤性极佳,从而使皮肤达到水油平衡。当保湿剂的加入量小于1%时,难以起到较好的保湿效果,当保湿剂的加入量大于8%时,肤感厚重,使用效果不好。优选地,所述保湿剂包括透明质酸钠、山梨醇、赤藓糖醇、海藻提取物中的一种或两种以上的组合。
在一些具体的实施方案中,本发明的保湿剂中包含有海藻提取物和透明质酸钠,以所述控油水凝乳的总重量计,所述透明质酸钠的加入量为0.01-0.5%,所述海藻提取物的加入量为1-6%。所述透明质酸钠与所述海藻提取物能够产生协同作用,进一步提高保湿效果。
根据本发明的控油水凝乳,其中,以所述控油水凝乳的总重量计,pH中和剂的加入量为0.05-1%;优选为0.2-0.4%;pH中和剂是用以维持或调节水凝乳酸碱度的物质。pH中和剂能够改变和维持水凝乳的酸碱度,使控油水凝乳的pH接近人体皮肤pH值。加入pH中和剂使得控油水凝乳具有一定的抗微生物作用,可以一定程度上延长控油水凝乳的保存期。优选地,所述pH中和剂为精氨酸。精氨酸是一种对人体有益的氨基酸,呈碱性,不仅可以护肤,还可以调节控油水凝乳pH值。
另外,化妆品常用的pH中和剂也可以是氢氧化钾、氢氧化钠、三乙醇胺、氨甲基丙醇等,但是氢氧化钾和氢氧化钠的碱性过强,对皮肤安全性有一定影响,而三乙醇胺和氨甲基丙醇有氨气气味,可能使得控油水凝乳产生不好的气味。本发明所述的pH中和剂优选选用精氨酸,其无色无味,温和亲肤,为控油水凝乳的温和性提供保障。
根据本发明的控油水凝乳,水的加入量为55-90%,优选为66-82%。
根据本发明的控油水凝乳,其中,所述控油水凝乳还包括防腐剂、香精、薄荷醇中的一种或几种;其中,薄荷醇具有薄荷香气并有清凉止痒作用,还能促进有效护肤成分的渗透和吸收;优选地,所述防腐剂的加入量为0.2-0.8%;优选为0.4-0.6%;所述香精的加入量为0.01-0.3%;优选为0.1-0.2%;所述薄荷醇的加入量为0.1-1%;优选为0.3-0.5%。
本发明还提供一种根据本发明的控油水凝乳的制备方法,包括将所述控油水凝乳的各组分混合的步骤。
根据本发明的控油水凝乳的制备方法,包括以下步骤:
将乳化剂、乳化稳定剂、空心微粉以及润肤剂加热混合均匀,得到油相混合物;
将保湿剂、增稠剂完全溶于水中,得到水相混合物;

对比例1-3
根据下表3中各组分的含量(份数),并且按照与实施例1-8相似的步骤制备得到对比例1-3的控油水凝乳。
表3
控油效果测试
<即时控油效果测试>
采用油脂测试垫法进行测试,其中左脸为测试面,右脸为空白对照面。使用皮脂油脂测试垫进行测试,其中该皮脂油脂测试垫为灰白色,吸油后会为黑色,并且油脂含量越高,颜色越黑。
在未涂抹控油水凝乳前,采用皮脂油脂测试垫测试左脸和右脸,左脸和右脸所使用的皮脂油脂测试垫均变为黑色;然后在左脸涂抹实施例6的控油水凝乳后,再次采用皮脂油脂测试垫测试左脸和右脸,其中左脸所使用的皮脂油脂测试垫的颜色基本没有变化,仍为灰白色;而右脸未涂抹控油水凝乳,所使用的皮脂油脂测试垫的颜色变为黑色。
同样地,实施例1-5以及实施例7-8制备得到的控油水凝乳也具备好的即时控油效果。
<即时控油效果测试>
采用VISA-CR面部图像分析仪,对油性肌肤测试者使用实施例6的控油水凝乳前以及使用实施例6的控油水凝乳后进行高清拍照,观察结果。
如图2所示,使用实施例6的控油水凝乳前,皮肤油光非常明显;使用实施例6的控油水凝乳后,皮肤油光消失,呈现自然清爽的正常状态。同样的,实施例1-5以及实施例7-8制备得到的控油水凝乳也具备能够使得皮肤油光消失,呈现自然清爽的正常状态的效果。
<持久控油效果测试>
使用德国CK公司的皮肤油脂测试仪测试皮肤油脂含量。选取12名志愿者成为受试者参加测试。受试者使用基准洁面乳清洁面部,洁面前测试原始油脂量,洁面擦干后测量初始油脂量。之后左脸涂用测试样品(0.040±0.002)g,为测试区;右脸不涂用任何化妆品,为空白区。测量2小时、4小时的皮肤油脂量变化。如下表4所示,其中,A表示使用实施例6制备得到的控油水凝乳的皮肤油脂量;B表示不涂任何化妆品的皮肤油脂量。
表4
由表4和图3可以看出,受试者在洁面后,使用测试样品前的皮肤油脂测量值没有明显差异;在使用控油水凝乳后第2小时,与空白对照样品比较控油效果显著;在使用控油水凝乳后第4小时,控油效果依然较好,而空白对照样品基本恢复到原始油脂量。说明实施例6制备得到的控油水凝乳具有持久控油效果,控油时间能够达到4小时以上。
同样的,实施例1-5以及实施例7-8制备得到的控油水凝乳也具有持久控油效果,控油时间也能够达到4小时以上。
对上述12名志愿者再次采用相同方法测试对比例1制备得到的含有亲水性中空硅石的控油乳液的持久控油效果。如下表5所示,其中,C表示使用对比例1制备得到的含有亲水性中空硅石的控油乳液的皮肤油脂量;D表示不涂任何化妆品的皮肤油脂量。
表5
由表5和图4可以看出,受试者在洁面后,使用测试样品前的皮肤油脂测量值没有明显差异;在使用对比例1的控油乳液后第2小时,与空白对照样品控油效果还算明显;但在使用控油水凝乳后第4小时,控油效果与空白样品接近,还比原始油脂量稍微偏高。说明对比例1的含有亲水性中空硅石的控油乳液只有短暂的控油效果,无法达到本发明的控油水凝乳的4小时以上持久控油的效果。
保湿效果测试
<皮肤水分含量测试>
采用德国CK皮肤水分含量测试仪进行测试,测试区域为两手前臂内侧,在样品使用前、样品使用后每0.5小时进行皮肤水分含量测试,至4小时停止。其中左手臂为样品测试区,右手臂为空白对照区。如下表6所示,其中,A表示使用实施例6制备得到的控油水凝乳的皮肤水分含量;B表示不涂任何化妆品的皮肤水分含量。
表6
由表6可以看出,实施例6制备得到的控油水凝乳具有很强保湿效果,保湿效果在4小时以上。
同样地,实施例1-5以及实施例7-8制备得到的控油水凝乳的保湿效果也较好。
