Abstract
本发明涉及O/W乳化剂、由该乳化剂制备的O/W乳液及其应用。根据本发明,O/W乳化剂包含(a)70-90重量%的油酸柠檬酸甘油酯和(b)10-30重量%的粘度为1-10,000mPas的粘度调节剂。
Description
本发明涉及O/W乳化剂、由该乳化剂制备的O/W乳液及其用途。
作为人体最大的器官,人的皮肤执行许多重要的功能。成年人皮肤平均表面积大约2m2,皮肤作为防护和感觉器官具有重要的作用。该器官的任务是传递和抵御机械、热、光化学、化学和生物刺激。它还在人体新陈代谢中作为调节器官和靶器官起着重要作用。
化妆品皮肤护理主要涉及加强或修复皮肤的天然功能,如抵御环境影响(例如灰尘、化学药品、微生物)和防止身体物质(如水、天然脂肪、电解质)丧失的屏障以及当它受损时支持其角质层的自然再生能力。如果皮肤的屏障性能被破坏,就会导致有毒或致敏性物质更大程度上的再吸收或导致微生物的侵袭,引起毒性或过敏性皮肤反应。皮肤护理的另一目的是补偿由日常清洗所引起的皮肤中脂肪和水分的丧失。这在自然再生能力不足的情况下尤其重要。皮肤护理产品还应该抵御环境影响、特别是阳光和风的影响,并延缓皮肤老化。
医用局部组合物一般包含一种或多种有效浓度的药物。简便起见,为了清楚地区分化妆品和医疗的用量以及得到相应产品,参考德意志联邦共和国的法律规定(例如,德国化妆品法令、食品法和药品法)。
乳液理解为包含两种液体的非均相体系,所述两种液体不能混溶或相互仅具有有限的混溶性,传统上称之为相。在乳液中,两种液体之一以极细微滴的形式分散在另一种液体中。如果这两种液体是水和油并且油滴微细分散在水中,那么它就是水包油型乳液(O/W乳液,例如奶)。O/W乳液的基本特征由水决定。在油包水型乳液中(W/O乳液,例如奶油),原理相反,基本特征由油决定。本领域技术人员自然知道配制用于化妆品或皮肤病应用的稳定O/W制剂的多种可能,例如以在室温至皮肤温度的范围内可以涂开的乳霜和软膏的形式或者是作为在该温度范围内更易流动的洗液、乳剂。这些体系通常含有乳化剂。
乳化剂是制备和稳定乳液的辅助物质,通常是油状至蜡状形式,还可为粉状物质。为了使得乳液长期稳定,需要乳化剂来抑制或延迟两相例如油和水的分离,直至乳液完成它的使命才达到热力学稳定的最终状态。
乳化剂降低两相之间的界面张力和减少界面活性并且稳定所形成的乳液。乳化剂通过界面膜和通过形成空间或电屏障来防止乳化颗粒流到一起(聚结),从而使所形成的乳液稳定。界面膜的弹性和粘度是乳液稳定中的重要因素,并受乳化剂的强烈影响。稳定已经形成的乳液是乳化剂最重要的性能,并且比促进各相的初级分布更为重要,因为相的初级分布可以采用足够的机械辅助来实现。乳化剂最重要的要求如下:
a)乳化剂必须集中在相间的边界层处。为此,它必须具有界面活性或表面活性,即减少不能混溶相之间的界面张力。
b)乳化剂还必须使颗粒带电,使得它们相互排斥或者在颗粒周围形成稳定的、通常是高粘度的或甚至是固态的保护层。
这些特性本身对许多应用来说是足够的。但是为了制备在特别长时期内稳定的乳液,必须防止已分散颗粒分层或沉降并且还要进一步减少它们的聚结趋势。这通过增加外相的粘度和/或形成保护性粘滞结构例如液晶或凝胶相来实现。在这种情况下,除了乳化剂本身,乳化剂体系还必须含有附加组分,该附加组分已知为辅助乳化剂、稳定剂或者根据活性机理而作为稠度调节剂(consistency modifier)或保护性胶体。
为了使化合物有效地成为乳化剂,它们必须具有独特的分子结构。这种化合物的结构特征是它们的两亲分子结构。这种化合物的分子具有至少一个亲高极性物质的基团(极性基团)和至少一个亲非极性物质的基团(非极性基团)。极性基团是其电子分布赋予分子相当大的偶极矩的官能团。这种基团决定了对极性液体的亲合力,尤其是对水的亲合力,以及化合物的亲水特性。因此,极性官能团也称为亲水基。
另一方面,非极性基团是分子中其电子分布对偶极矩没有显著贡献的那部分。非极性基团决定了对非极性液体的亲合力,尤其是低极性有机溶剂,因此这种官能团也称为亲油基。在分子中亲水基和亲油基的结合存在使得乳化剂能同时与亲水相和亲油相作用。这导致了在界面上的定向,这种定向是该化合物的界面活性的前提。
乳化剂表征的决定性特征是分子中亲水和亲油构成的比率,表示为亲水-亲油平衡(HLB体系),有许多实验和理论数学方法来确定该特征,所有的这些方法均基于确定分子组成中亲水基对亲油基的比率。具有高HLB值的乳化剂产生O/W乳液,具有低HLB值的乳液优选形成W/O乳液。
但是,从现有技术中已知仅有少数O/W乳化剂形成这种低粘度且例如可以喷射的O/W乳液。它们大多含有聚乙二醇。另外,现有技术的低粘度O/W乳液通常具有不稳定、应用限于狭小范围或成分选择严格等缺点。因此,目前在市场上还没有低粘度、可冷处理的O/W乳液,例如充分稳定的高极性油,所述高极性油例如其他常用于商品中的植物油。根据现有技术,配制具有低粘度并表现出如市售产品所需的贮存稳定性的O/W乳液存在巨大的困难。因此这种配方的选择受到极大的限制。但是,该配方会给消费者提供前所未知的化妆好处。
从EP 1 049 452中已知一种低粘度的化妆或皮肤病用O/W乳液,其含有一种或多种部分中和的饱和脂肪酸单酸甘油酯和/或二酸甘油酯与柠檬酸的酯和一种或多种选自包含具有12-40个碳原子的支链和非支链烷基醇的脂肪醇。
US 2003/0012801公开了一种特殊的乳液,其含有一种或多种部分中和的饱和脂肪酸单酸甘油酯和/或二酸甘油酯与柠檬酸的酯、环糊精和类维生素A。
从WO 99/62468中已知一种毛发护理剂,除了特定的季戊四醇酯油外,其还含有第二油组分。其中作为第二油组分的实例,要求保护通式中具有1-30个碳原子的不饱和烷基的柠檬酸酯油。没有列出这类物质的具体化合物。
本发明的目的具体而言是提供克服现有技术缺点的O/W乳化剂。
通过具有权利要求1中所述特征和与其相关的用途的O/W乳化剂来实现该目的。
根据本发明,O/W乳化剂含有
(a)70-90重量%的油酸柠檬酸甘油酯(glyceryl oleate citrate)和
(b)10-30重量%的粘度为1-10,000mPas的粘度调节剂。
根据本发明的O/W乳化剂主要特征如下:
-通过热/热、热/冷和尤其是冷/冷处理,制备O/W乳液的能力;
-甚至在例如小于2%的低浓度下使用时,形成热稳定乳液;
-多方面的适用性,适用于较高粘度的乳霜、中粘度的乳剂和洗液,和适用于低粘度的可喷射洗液;
-与已知的O/W乳化剂相比,在乳液体系中的固体分散性改善;
-与已知的O/W乳化剂相比,所混合固体的分散性更大;
-以此设计的配方中具有基本与pH无关的特性;
-能够用于具有极性和非极性油的配方中;
-与水凝胶前体和水胶体的相容性;
-没有聚乙二醇;
-能够与辅助乳化剂和稠度调节剂组分组合;和
-能够与UV-A和UV-B滤光剂组合以改善防晒产品的水附着性。
用该乳化剂制备的O/W乳液主要特征如下:
-低能耗生产:水相或者甚至是水和油相(具有适当选择的其它组分)均可冷处理,
-良好的粘度稳定性,
-高pH稳定性,
-良好的温度稳定性,
-具有光滑表面的非常微细和均匀的乳液结构,
-直接加入极性和非极性油,其中优选可以经水相或油相加入O/W乳化剂,和
-有关采购和贮存用于洗液和乳霜的单一O/W乳化剂的商业和运销优势。
油酸柠檬酸甘油酯优选是单油酸和/或二油酸甘油酯与柠檬酸的酯,其中具体是可以通过柠檬酸与单油酸甘油酯以0.3∶1-1.5∶1,优选0.7∶1-1.2∶1的摩尔比进行酯化反应得到该酯。具体地,具有上述特性的油酸柠檬酸甘油酯改善O/W乳化剂和基于它的乳液的稳定性。
还优选油酸柠檬酸甘油酯通过中和而具有5-8的pH值,特别是5.8-6.2,尤其是6.0(每种情况下均在10%的1∶1水/甲醇混合物中测量)。尤其优选完全中和的酯。例如氢氧化钠适合用于中和。
根据本发明的O/W乳化剂中的油酸柠檬酸甘油酯优选具有9-15的HLB值,尤其是11-13。
还优选O/W乳化剂中的油酸柠檬酸甘油酯即组分(a)的比例为75-85重量%,尤其是80重量%。
经过上述改进,O/W乳化剂的长期稳定性可明显改善而且可以支持稳定O/W乳液的生产。
还优选粘度调节剂的粘度为1-1000mPas,尤其优选1-100mPas。通过符合特定的范围限制,可以调节O/W乳化剂的流变性,以使其在室温下自由流动。这允许O/W乳液进行冷处理。所述粘度值在每种情况下均对25℃有效并利用配有适用于特定粘度范围的转子(spindle)的布氏粘度计(Brookfield viscometer)(RV型)在合适的测量转速下测得。测定根据本发明的纯粘度调节剂的粘度时,用于测量动态粘度的其它合适的粘度计可用来替代指定的粘度计,这是由于一般来说它们提供的结果仅略微不同。
粘度调节剂优选天然油,尤其是辛酸/癸酸三酸甘油酯(CAS登记号65381-09-1)。后一种粘度调节剂是混合物的形式且包含在三酸甘油酯中的脂肪酸优选具有含量为50-72重量%的辛酸和含量为26-45重量%的癸酸。选择辛酸/癸酸三酸甘油酯本身作为粘度调节剂对O/W乳化剂和由其制备的乳液的稳定性具有令人惊讶的积极影响。辛酸/癸酸三酸甘油酯例如可以从Henkel KGaA,Germany获得,商品名为Myritol或从Symrise GmbH & Co.KG.Germany获得,商品名为Neutral Oil(2/950160)。
乳液形式的化妆和皮肤病用组合物优选含有占整个配方比例为2-5重量%的根据本发明的O/W乳化剂。如果在上述类型的组合物中使用辅助乳化剂,那么在整个配方中它们的含量优选为1-10重量%。任选存在的任意稳定剂在整个配方中的含量优选为0.1-5重量%。
已经发现,乳液中的油酸柠檬酸甘油酯或O/W乳化剂单独或者与其它化妆性辅助物质一起具有下列效果:
提高UV滤光剂的防晒系数(UVA和/或UVB防护);稳定UV滤光剂(改善耐光性);改善固体UV滤光剂的溶解性和/或悬浮性;增加防晒产品的耐水性;支持凝胶网络结构的形成;增加活性物质例如抗氧化剂、防腐剂、亮肤剂和晒黑剂、芳香油、螯合剂的有效性;增加活性成分在皮肤和/或毛发上的牢固性;改善化妆用油(植物油、矿物油、柔润剂)、活性成分、维生素、芳香油和精油在皮肤上的分布;支持相斥的活性成分均匀分布;有助于水相中防腐剂体系的最佳分布;支持皮肤的屏障功能;减少无机UV滤光剂(二氧化钛、氧化锌)和彩色颜料的聚结率;支持止汗剂产品中铝盐的分布;与醇以及乙醇相容;作为主或辅助乳化剂改善乳液的稳定性。
配方实例:护肤霜(O/W)、爽身水、防晒霜(O/W)、防晒乳(O/W)、喷雾防晒乳(O/W)、敏感香液滚珠(sensitive balsam roll-on)和霜(O/W)、喷雾祛臭液、止汗液、护发素(hair treatment rinse)、男士发胶蜡(hair gel wax)、发乳、彩色日霜、睫毛膏、湿拭纸用调湿液。
油酸柠檬酸甘油酯或O/W乳化剂可以与光稳定剂一起调配。合适的光稳定剂为例如有机UV吸收剂,该有机UV吸收剂来自4-氨基苯甲酸及其衍生物、水杨酸衍生物、二苯甲酮衍生物、二苯甲酰甲烷衍生物、二苯基丙烯酸酯、3-咪唑-4-基丙烯酸及其酯、苯并呋喃衍生物、丙二酸亚苄酯衍生物、聚合物UV吸收剂(含有一种或多种有机硅基团)、肉桂酸衍生物、樟脑衍生物、三苯胺基-s-三嗪衍生物、2-羟苯基苯并三唑衍生物、2-苯基苯并咪唑-5-磺酸及其盐、邻氨基苯甲酸基酯、苯并三唑衍生物。
油酸柠檬酸甘油酯或O/W乳化剂还可以混入含有颜料优选微粒颜料的化妆和/或皮肤病用制剂中。它们可以是有机或者无机颜料。优选的有机颜料是2,2’-亚甲基二-[6-(2H-苯并三唑-2-基)-4-(1,1,3,3-四甲基丁基)苯酚](TinosorbM)。基于难溶或不溶于水的金属氧化物和/或其它金属化合物的无机颜料或微细颜料具体是钛的氧化物(TiO2)、锌的氧化物(ZnO)、铁的氧化物(例如Fe2O3)、锆的氧化物(ZrO2)、硅的氧化物(SiO2)、锰的氧化物(例如MnO)、铝的氧化物(Al2O3)、铈的氧化物(例如Ce2O3)、相应金属的混合氧化物(mixed oxide)和这些氧化物的混合物。这些颜料是X-射线无定形的或者是非X-射线无定形的。尤其优选基于TiO2和ZnO的微粒颜料。
油酸柠檬酸甘油酯或O/W乳化剂还可以混入到具有传统组成的化妆和/或皮肤病用制剂中,并用于化妆和/或皮肤病遮光,还用于皮肤和/或毛发的修护、调理和清洁和在彩妆中作为粉底产品。根据它们的结构,这种制剂可因此用作护肤霜、洁肤奶、防晒液、皮肤养料、日或晚霜等。这种制剂因此可以采用诸如乳液、洗液、乳剂、霜、水分散凝胶、香膏、喷雾、泡沫、香波、护发产品、毛发调理剂、滚珠、棒或粉底(make-up)的形式。
任选可以并有利的是,使用这种制剂作为药用配方的基础。具体优选为护肤或粉底产品形式的这种化妆和皮肤病用制剂。
