Abstract
本发明涉及一种透明的洁齿乳膏。它含有10-15重量%硅酸抛光剂、55-70重量%保湿剂、15-30重量%水和2-10重量%其它牙膏成分。所述洁齿乳膏的粘度在10000-100000 mPas(20℃)范围内。如果由山梨醇(a)、甘油(b)和聚乙二醇(c)按重量比(a)∶(b)∶(c)=10∶(7-8)∶(0.5-1.5)组成的混合物作为保湿剂,它可以容易地从给料软管中流出。优选水和保湿剂的重量比为1∶(2-3)。
Description
本发明涉及一种含有一定量的抛光剂、保湿剂和水的洁齿乳膏。它呈充分透明至清澈状并具有良好的流变性能,能应用塑料软管给出准确的剂量。
现有技术已知多种洁齿乳膏,如专利WO94/01080 A1公开的洁齿乳膏,它能在很轻的按压下,容易地从塑料软管中流出。这些产品的外观为白色至暗灰色。为了使这些产品变成透明或清澈,要求水、保湿剂和必要时具有一定溶解度的与抛光剂具有相似的折射率的液体载体。专利WO95/22958公开了一种透明的洁齿乳膏,它含有大于50重量%的山梨醇。但是这种洁齿乳膏不能在低温下保持满意的透明度。专利WO94/01081 A1也公开了一种透明洁齿剂,它含有约21重量%山梨醇、30%重量%甘油和5重量%乙醇。这些洁齿乳膏粘性均很低,其粘度明显地小于10000mPas(25℃)。
本发明的目的是提供一种洁齿乳膏,它既使在低温下也能保持透明,并具有一定粘性,在挤压到牙刷上时,乳膏不会从软管中流出太快,乳膏也不会太深地下沉到鬃毛的间隙中。
因此本发明的解决方案是应用一种特效的混合保湿剂。本发明的对象是一种含有10-15重量%硅酸抛光剂、55-70重量%保湿剂(a+b+c)、15-30重量%水和2-10重量%其它牙膏成分的透明洁齿乳膏,其特征在于,含有由山梨醇(a)、甘油(b)和聚乙二醇(c)按重量比(a)∶(b)∶(c)=10∶(7-8)∶(0.5-1.5)组成的混合物作为保湿剂。
本发明的洁齿乳膏具有液体性质,它的粘度在10000-100000mPas范围内(20℃时采用型号为RVF的Brookfield的旋转粘度计,在4RPM时,转轴3/4,相应地剪切率D=4/秒)。本发明的洁齿乳膏既能容易地从塑料给料软管中流出,又缓慢地下沉到牙刷的鬃毛间隙中。
本发明的洁齿乳膏的透明性至少必须达到下述程度,透过约1cm厚的洁齿乳膏层(如放在边长1×1×4cm的透明玻璃板上)还能很好地看清约4mm高、3mm宽的字母体。
所有已知可作为抛光剂的凝胶硅酸、水凝硅酸和沉淀硅酸均适合作为硅酸-抛光组分。通过用无机强酸转化硅酸钠生成水溶胶,经过陈化生成水凝胶,再经清洗和干燥生成凝胶硅酸。如专利US 4 153 680所公开的,在保护性条件下干燥将水含量降到15至35重量%,得到所谓的水凝硅酸。又如专利US 3 538 230所公开的,通过干燥将水分降到15重量%以下,使原先的水凝胶的疏松结构经过不可逆的收缩变成所谓的干凝胶的致密结构。
第二优选的适宜的硅酸-抛光剂是沉淀硅酸。在不出现溶胶和凝胶的条件下,通过加入强酸,使硅酸从碱金属硅酸稀溶液中沉淀析出。如专利DE-OS 25 22 486和DE-OS 31 14 493所公开的生产沉淀硅酸的适宜方法。优选根据专利DE-OS 31 14 493所公开的生产方法生产的沉淀硅酸是适宜的,其比表面(BET)为15-110m2/g,粒度为0.5-20μm,其中至少必须有80重量%初生颗粒的粒度小于5μm。10-20重量%牙用凝胶在含30%甘油-水(1∶1)-乳化剂中,其粘度为30-60 Pa·s(20℃)。此外优选具有园棱角类型的适宜沉淀硅酸,其商品名称为Sident12DS(DEGUSSA)。
这种类型的另一些沉淀硅酸是Sident8(DEGUSSA)和Sorbosil AC39(Crosfield Chemicals)。这种硅酸比表面在40-75m2/g(根据BET)的情况下,其特点是具有较小的增稠作用和较高的平均粒度,其范围为8-14μm。它特别适用于根据本发明的洁齿乳膏。
其它的抛光剂,特别是指具有某种折射率的抛光剂,它每多含0.1偏差就有1.45μm,优选不含这种抛光剂或至多含有小于2重量%的抛光剂。
对根据本发明的洁齿乳膏的流变性能和透明性具有决定作用的是水载体液相和保湿剂的成分。总量为55-70重量%的保湿剂是由山梨醇(a)、甘油(b)和聚乙二醇(c)按范围相对较窄的量比(a)∶(b)∶(c)=10∶(7-8)∶(0.5-1.5)组成。因此在优选的山梨醇含量为30-35重量%时,甘油含量为21-28重量%和聚乙二醇含量为1.5-5.25重量%。
优选含有水(d)和保湿剂(a+b+c)的重量比是(d)∶(a+b+c)=1∶(2-3)。在优选保湿剂含量为55-65重量%时,水含量为20-25重量%。其中水含量是通过如含70%山梨醇或含86%甘油等的原料中带入的水和单独加入水的总和。所给出的山梨醇和甘油的数量是针对无水的活性物质而言。
根据本发明的洁齿乳膏,除了含有上述必需加入的组分外,还可以含有其它的牙膏成分,这些物质的种类和含量对透明性不应有负面影响。这些成分,如粘合剂、表面活性剂、调味剂、治牙病和牙龈病的活性物质例如氟化物、抗牙石活性物质、抗菌物质(如双胍、二十三烷)、维生素、泛酰醇和其它活性物质。
最后根据本发明的透明洁齿乳膏非常突出的是,通过加入溶解的染色剂和/或色素于产品中得到所要求的外观颜色。特别适宜作为色素颗粒的有商品Sorbosil BFG51、BFG52和BFG55或Sorbosil SD2352。有时也可应用不同色素颗粒的混合物。根据本发明的洁齿乳膏可含有构成深橙色、红色或兰色的含量为0.1-1.0重量%的有色凝胶硅酸颗粒。
作为粘合剂可使用天然的和/或合成的聚合物,如藻酸酯、角叉菜胶、黄蓍胶、淀粉、淀粉醚,纤维素醚如羧甲基纤维素(Na盐)、羟基乙基纤维素、甲基羧基丙基纤维素,瓜耳树胶、阿拉伯树胶、琼脂、黄原胶、琥珀聚糖胶、稻子豆粉、果胶、水溶的羧基乙烯基聚合物(如Carbopol-类型)、聚乙烯醇、聚乙烯吡咯烷酮、聚乙二醇,特别是分子量为1500-1000000的聚合物。
特别适宜的粘合剂是黄原胶、羧甲基纤维素、聚乙烯吡咯烷酮和这些聚合物的混合物,其含量为小于0.5重量%。
合适的表面活性剂是如在烷基中有12-18个碳原子的直链烷基硫酸钠,这些物质对牙垢的细菌物料交换,还附加地具有抑制酶的作用。其它合适的表面活性剂是碱金属盐,优选在直链烷基中有12-16个碳原子和在分子中有2-6乙二醇醚基的烷基聚乙二醇硫酸钠酯、直链烷烃(C12-C18)-磺酸钠酯、磺基琥珀酸烷基(C12-C18)钠酯、硫酸处理过的脂肪酸-丙三醇钠酯、硫酸处理过的脂肪酸链烷醇酰胺钠盐、磺基乙酸烷基(C12-C16)钠酯、酰基肌氨酸、酰基牛磺酸和在酰基中有8-18个碳原子的酰基羟乙基磺酸盐。此外两性离子的、两性电解质的和非离子的表面活性剂均是合适的,如脂肪酸单乙氧基酯和脂肪酸脱水山梨醇酯的乙氧基甘油二酯和烷基(低分子量)葡糖苷。
优选月桂基硫酸钠盐和月桂基硫酸钠盐与椰子氨基丙基甜菜碱的混合物作为表面活性剂。
作为调味剂应用的有常用的香料和甜味剂。合适的香料有如薄荷油、变种卷叶薄荷油、按叶油、大茴香油、小茴香油、枯茗油、乙酸甲酯、肉桂醛、大茴香脑、香草醛、麝香草酚和其它天然的或与天然相同的醚类油,也可应用合成的调味料。
合适的甜味剂有糖精、环己基氨基磺酸钠酯、蔗糖、乳糖、麦芽糖和果糖。
其它的常用牙膏成分是:
-防腐剂和抗菌物质:如对羟基苯甲酸甲酯、对羟基苯甲酸乙酯、对羟基苯甲酸丙酯、山梨酸钠酯、苯甲酸钠酯、溴氯代苯酚、二十三(碳)烷、合克替啶、水杨酸苯基酯、双胍如洗必太和过氧化物;
-氟化物:如氟化钠、氟化锌、一氟磷酸钠、氟化铵;
-缓冲物质:如碱金属的磷酸盐、磷酸一氢盐、磷酸二氢盐、柠檬酸-柠檬酸钠;
-创口愈合物质和消炎物:如脲、尿囊素、泛酰醇、碱性绕丹宁、甘菊生物活性物质(甘菊环)和乙酰水杨酸衍生物;
-维生素:如维生素A、维生素E或维生素C;
-矿物盐:如锰盐、锌盐或镁盐。
在根据本发明的洁齿乳膏中所有这些可随意选择的牙膏成分的总量为2-10重量%。
下述的实施例将进一步说明本发明:
