Abstract
本发明涉及一种在水溶液中可再分散的聚合物粉末、该粉末在化妆品或药物制剂中或植物保护制剂中的应用以及一种制备在水溶液中可再分散的聚合物粉末的方法,该聚合物粉末含有含自由酸基或碱基的共聚物,有时还含有助剂,该方法的特征在于,在干燥之前,通过加入至少一种缓冲剂系统,将分散体的pH值在含有酸基的共聚物情况下调节到pH为2.0-6.5或在含有碱基的共聚物情况下,将pH值调节到pH为7.5-12。
Description
本发明涉及一种制备在水溶液中可再分散的聚合物粉末的方法,该聚合物粉末含有含自由酸基或碱基的共聚物,有时还含有助剂,该方法的特征在于,通过加入一种缓冲剂系统,将分散体的pH值在含有酸基的共聚物情况下,调节到pH为2.0-6.5,或在含有碱基的共聚物情况下调节到pH为7.5-12。
此外,本发明还涉及水溶液中可再分散的聚合物粉末以及其在化妆品或药物制剂中或者植物保护组合物中的应用。
专利DE 2 512 238公开了由水状塑料分散体制备成膜共聚物粉末,这种成膜粉末在有机溶剂中溶解后可用以涂敷固体药物制剂。
应用有机溶剂涂敷固体药物制剂引起了相应大的技术问题。所有使用的设备必须设计成防爆型,以防溶剂着火。从环保和成本原因考虑,必须从废气中回收蒸发出的溶剂。此外必须完全除去药物制剂中的溶剂。因此要寻找使用有机溶剂的替代物。
因此研究了一系列用水作溶剂的方法,但这些方法也存在许多缺点。
Bright等在美国专利5 252 704中公开了可再分散的共聚物粉末,此共聚物粉末是在喷雾干燥前通过加入大量的聚乙烯吡咯烷酮从共聚物制备的。但加入高百分比的聚乙烯吡咯烷酮对成膜后所得的共聚体膜的溶解度有不利的影响。
EP-B 88 951和EP-B 161 326描述了含自由羧基或氨基并可将这些基团转变成其盐的乳液聚合粉末的再分散性。其中自由羧基通过加入碱转变成其盐以及自由氨基,通过加入酸转变成其盐。它是在聚合物分散体干燥后通过向在水中细分散的含有羧基的聚合物粉末中搅拌加入碱性溶液实现的。
如聚合物含有自由氨基,即搅拌加入酸性溶液以形成分散体。
对含羧基的聚合物情况,描述了喷雾干燥前通过加入碱使自由羧基部分中和的可能性。
但在这种情况下,分散体的粘度以及喷雾干燥前的凝块形成是关键参数。假如干燥前加入碱,则在接着的再分散中容易形成不希望的凝块。因此聚合物粉末的中和,也就是说形成盐,最好在粉末干燥后,正好在制备固体药物制剂前进行。由此对于用户来说,就必须配置中和作用的附加设备以及碱和酸的贮存设备。
因此本发明的目的是研制一种可再分散的聚合物,它能直接分散以形成水溶液而又无上述缺点,并可使其在化妆品及药物领域以及植物保护中应用。
已发现,在干燥之前通过加入至少一种缓冲剂系统,在含有酸基的共聚物情况下,将分散体调节到pH为2.0-6.5或在含有碱基的共聚物情况下,将分散体调节到pH为7.5-12,可制备出特别好的可再分散的聚合物粉末。
本发明的贮存性很稳定的聚合物粉末在水溶液中能很快再分散,而不会形成例如结块。
因此它适宜在化妆品或药品制剂中或植物保护制剂中作为特别好的成膜剂。
所有已知的缓冲剂,例如在“生物化学手册”(Hand Book ofBiochemistry)(Sober,H.A.,Horte R.A.,化学橡胶公司,TheChemical Rubber Co.,1968:J-195-J-199)所述的缓冲剂原则上适宜于本发明的方法。
对含有含自由酸基或碱基的共聚物的分散体,在干燥前最好通过加入至少一种缓冲剂系统,在含有酸基的共聚体情况下,将其调节到pH为2.0-6.5;或在含有碱基的共聚物的情况下,将其调节到pH为7.5-12。优选的是,在干燥前对含有酸基的共聚物情况,将其pH值调到pH为3.0-6.0,对含有碱基的共聚物情况,将其pH值调到pH为7.5-11。通过调节pH值,使共聚物的一部分自由酸基或碱基转化为其盐类。
缓冲剂系统是通常的缓冲剂和/或聚合物缓冲剂。
适宜的缓冲剂是例如由弱酸和强碱或强酸和弱碱形成的所有盐类,其中可以是同一类的酸或碱的盐类或者由不同的酸或碱的盐类混合物。
在含有自由酸基的共聚物情况下使用的缓冲剂例如含自由膦酰基、磺基、或羧基的共聚物至少包含一种缓冲剂系统。该缓冲剂系统的缓冲范围优选为pH1-7。具有pH为1-7的酸性缓冲范围的合适的缓冲剂或缓冲剂溶液例如是Wolpole-缓冲剂(醋酸/醋酸钠,pH3.65.6)、Gomori-乌头酸盐-缓冲剂(乌头酸/NaoH,pH2.5-5.7)、Kolthoff-缓冲剂(四硼酸钠/琥珀酸盐,pH3.0-5.8)、Sorensen-柠檬酸盐-缓冲剂(柠檬酸二钠/HCl,pH 2.2-4.8)、Sorensen-甘氨酸Ⅰ-缓冲剂(甘氨酸,NaCl/HCl,pH1.2-3.6)、Clark和Lub-苯二甲酸氢盐Ⅰ-缓冲剂(苯二甲酸氢钾/HCl,pH2.2-3.8)、Clark和Lub-苯二甲酸氢盐Ⅱ-缓冲剂(苯二甲酸氢钾/NaOH,pH4.06.2)、Smith和Smith-哌嗪-缓冲剂(哌嗪,HCl/NaOH,pH4.8-7.0)、Clark和Lub-氯化钾/HCl-缓冲剂(KCl/HCl,pH1.0-2.2)、Gomori-三顺丁烯二酸盐-缓冲剂(三顺丁烯二酸盐/NaOH,pH 5.2-8.6)或Gomori-琥珀酸盐-缓冲剂(琥珀酸盐/NaOH,pH3.8-6.0)。同样,缓冲剂如MES、ADA、PIPES或ACES,这些是生物化学中常用的缓冲剂,或氨基酸缓冲剂均是适宜的缓冲剂。优选的缓冲剂最好是由弱酸及其盐制成的各种缓冲剂,例如醋酸钠/醋酸,硼酸钠/硼酸,磷酸钠/磷酸,碳酸氢钠/苏打,氢氧化钠/柠檬酸,氢氧化钠/酒石酸。由弱碱及其盐制成的缓冲剂也是适宜的。可用单个缓冲剂或其混合物来调节分散体的pH值。在含有自由碱基的共聚物例如含自由的N-烷基、氨基、或亚氨基的共聚物情况下使用的缓冲剂至少是一种缓冲系统。该缓冲剂系统的缓冲范围优选为pH7-13。具有pH为7-13的碱性缓冲范围的合适的缓冲剂或缓冲溶液如Clark和Lub-硼酸盐缓冲剂(硼酸,KCl/NaOH,pH7.8-10.0)、Delory和King-缓冲剂(碳酸盐/碳酸氢盐,pH 9.2-10.7)或Sorensen-甘氨酸Ⅱ-缓冲剂(甘氨酸,NaCl/HCl,pH8.4-13)。同样,缓冲剂如氯化胆氨、BES、TES、HEPES、乙酰胺甘氨酸、甘氨酰胺、Tris、Bicine、Tricine或N-甘氨酰甘氨酸,这些是生物化学中常用的缓冲剂,或氨基酸缓冲剂均是适宜的缓冲剂。
优选的缓冲剂最好是由弱酸及其盐制成的各种缓冲剂。由弱碱及其盐制成的缓冲剂也是适宜的。可用单个缓冲剂或其混合物来调节分散体的pH值。
假如将聚合物缓冲剂或者缓冲剂溶液用于中和共聚物的自由酸基或碱基,则这些聚合物缓冲剂最好是通过加入中和剂到含有自由酸基或碱基的聚合物中。适用的聚合物是含自由酸基或自由碱基的共聚物,它是通过(甲基)丙烯酸、其衍生物、马来酸、富马酸、衣康酸、巴豆酸、乙烯基磺酸、聚乙烯亚胺的乙烯基膦酸和/或其盐,其酯以及还可以是其酐的自由基引发聚合而得。合适的酐是例如丙烯酸酐,甲基丙烯酸酐或马来酸酐。用于制备聚合物缓冲剂的聚合物也可以是含自由酸基或自由碱基例如藻酸或透明质酸的天然聚合物。分散体和所加入的聚合物缓冲剂溶液的单体组成可以是相同的或不同的。聚合物缓冲剂或者聚合物缓冲剂溶液最好是通过将中和剂加到一部分干燥的分散剂中来制备。在制备聚合物溶液时,可部分地或全部地进行单体的中和。能形成盐的缓冲剂聚合物单体最好有50-100%(重量)是呈盐状。优选是70-95%(重量)的单体是呈盐状。中和完全的是最特别优选。按聚合物含有的自由基的种类来选用进行中和所采用的酸或碱。所有生理上可接受的碱或酸例如氢氧化钠,醋酸钠,磷酸钠,苏打,柠檬酸,酒石酸,磷酸,醋酸和/或蚁酸是合适的中和剂。但上述缓冲剂或缓冲剂溶液也是适宜的。
用于中和的各种酸,碱或缓冲剂或其组合均可用于制备聚合物缓冲剂溶液。
原料分散体可简单的通过加入至少一种缓冲剂系统将其调节到酸性或碱性pH值,此分散体经干燥后就转化成可再分散的粉末。各种缓冲剂和/或聚合物缓冲剂或缓冲剂和/或聚合物缓冲剂的混合物是适宜的缓冲剂系统。
与成盐基团性质无关,相同的缓冲剂和/或聚合物缓冲剂均可在所有情况下使用。在此不需外加附加的酸或碱。虽然这也是可能的,即对于在未加缓冲剂情况下通过自由基引发聚合并经干燥所获得的分散剂粉末可通过至少在一种缓冲剂和/或至少一种聚合物缓冲剂中搅拌而使其再分散。
由于经济原因,待干燥的分散体的固体含量一般大于25%(重量)。当从这种分散体制备聚合物缓冲剂溶液时,最好将固体含量先调节到小于15%(重量),并且接着再加入中和剂。
以此方法制备出的稀释的聚合物缓冲剂溶液接着与待干燥的分散体混合。
由分散体和缓冲剂和/或聚合物缓冲剂溶液组合的固体含量处于1-50%(重量)之间。优选是5-40%,特别优选是20-35%(重量)。
按本发明经加缓冲剂和/或聚合物缓冲剂制备出的分散体在加工时可适应pH值波动,而不会形成凝块,这也是其优点。通过添加缓冲剂,解裂pH值,即聚合物开始膨胀并接着开始溶解的pH值在精确范围内变动。假如希望活性化合物可控释放,并且达到最佳的生物适应性,这点是特别的优点。

此外还可加入其它的添加剂,如动物和植物脂肪,优选是其加氢形式,特别是那些在室温下(20℃)为固体的脂肪。这些脂肪的融点最好为50℃或更高。优选是C12-,C14-,C16-和C18-脂肪酸的三甘油酯。蜡如巴西棕榈蜡、小烛树蜡、小冠巴西棕蜡、甘蔗蜡、瑞太明-蜡(Ratamo-Wacho)动物蜡如蜂蜡、虫胶蜡、昆虫蜡或羊毛蜡、石油蜡、褐煤蜡、泥煤蜡和其它褐煤蜡(地蜡)、聚烯烃蜡、烷烃蜡、酸蜡、酯蜡、醇蜡或酰胺蜡亦能满足相同的功能。蜡可以是天然的、改性的、部分或全部合成的。当然各种蜡的成分如蜡酸、蜡醇、蜡酮、羟基蜡酸、石蜡、树脂酸、聚萜烯、树脂醇、甘油硬脂酸酯、凡思林或脂肪酸或混合物也能列入其中。
这些脂类,蜡类,脂或蜡的衍生物能单独的或与单和/或双甘油酯或磷脂,特别是卵磷脂共混合是有益的。单和双甘油酯最好是取自上述的脂肪类型,即C12-,C14-,C16-和C18-脂肪酸。
再者各种乳化剂也适宜作为助剂。市售乳化剂见M.和I.Ash的“工业用表面活性剂手册”(Handbook of Industrial Surfactans),Gower出版公司,Hants,1933。它们可以是低分子量的化合物或聚合物。低分子量化合物一般含有直键的或分枝的,饱和的或不饱和的、环状的或非环状的、芳香族的或脂肪族的、在分子中含8-40,优选为10-30,特别优选为12-22碳原子的烷基基团。

聚合反应可间歇的或连续的进行,可用或不用种子聚合物,加料方法可为:起始加入反应混合物的所有或某些组分,或首先部分加入,然后补加所有或某些反应混合物的组分,或无起始加料,而按计量加入组分。
例如在DE-A-4 325 158中公开了沉淀聚合方法。
为干燥已制备成的分散体,可使用通常的干燥工艺,如薄膜干燥、流化床喷雾干燥、喷雾干燥或冷冻干燥。
待喷雾的分散体也可含有喷雾助剂,如聚乙烯醇、纤维素衍生物、淀粉衍生物、木质素磺酸钠、聚丙烯酸和聚丙烯酰胺。作为抗结块剂可加入例如硅酸铝如膨润土、硅藻土(Kieselgur)、胶状的硅胶、硅藻土(Diatomeenerde)、碳酸钙、硅酸镁如滑石粉或磷酸三钙。
喷雾最好利用液体压力或空气压力,经喷嘴例如单组分喷嘴、多组分喷嘴或圆盘式喷嘴并采用常用的喷雾设备以流体动力学雾化来实现。
基本原理是溶液经喷雾成很小的液滴。此种小液滴有很大的表面积,可使其快速蒸发。通过喷雾器转轮速度或喷雾器气体压力达到所需的小液滴的小直径。所达到的蒸发度足够从液滴中除去全部水分。通过蒸发冷却和短的悬浮时间防止了产品的受热损坏。
可在常用的喷雾塔中进行小液滴的干燥,其中用空气或者惰性气体如氮气,氩气或氦气作干燥用气,气体以与液滴成同流或逆流流过干燥塔。干燥用气最好以同流方式加入,气体在塔入口处温度为60-160℃,最好为90-140℃,在塔的出口处为40-100℃,最好是60-80℃。溶剂的蒸发既可在常压下也可在0.6-1.2巴的压力下进行。
所形成的粉末可以常用方法经旋风分离器与气流分开。
如此形成的粉末所含的剩余溶剂一般不超过7.5%(重量)。所形成的粉末颗粒的大小一般为10-150μm。喷雾造粒中颗粒大小可达到450μm。
与现今技术水平比较,本发明的在水溶液中可再分散的聚合物粉末有显著好的再分散性。在所有试验中再分散度>90%。其优点是,由本发明的分散体制得的薄膜比由原料分散体制得的薄膜溶解得更快。因此在小肠中,活性化合物能更快地从有涂敷层的药物中释放出。
本发明的可再分散的分散体粉末或者由此制备的各种分散体或其它的二次产品适宜于所有固体或半固体化妆品或药物制剂或用于植物或动物保护的组合物。
固体或半固体的化妆品或药物制剂的形式包括例如片、含活性化合物的晶体、微型片、糖衣片、锭剂、丸、胶囊、微胶囊和颗粒,但不应仅限于这些形式。
可再分散的分散体粉末的一种特殊的应用是可穿过皮肤的治疗系统的制剂。
植物保护的应用包括害虫的外激素捕获,它要求外激素能有目的的持续地释放。
