Description

一种液体创可贴及其制备方法
技术领域
本发明涉及一种液体创可贴及其制备方法。
背景技术
液体创可贴是由成膜材料溶解在溶剂中,加入功能性物质组成。通过涂抹或喷洒紧紧黏附与皮肤创伤部位,形成保护膜。其相比传统创可贴,具有防水、透气、使用简单方便、不受伤口所处位置的限制等优点。
现有液体创可贴一般采用氰基丙烯酸酯类、硝化纤维素、聚乙烯醇(PVA)、聚乙烯醇缩醛(PVB)、壳聚糖等为成膜材料,加入功能性物质起到杀菌消炎促进愈合作用。但现有技术存在着合成方法繁琐,并且有红肿痒等现象出现。
CN104998295 A专利公开了一种液体创可贴及制备方法,其原料组成为:苦参碱1-5%,氧化苦参碱1-5%,大蓟10-15%,冰片1-2%,甘油0.5-2%,透皮促进剂0.5-5%,成膜剂3-8%。此专利工艺合成方法复杂,需要先将大蓟提前制成煎膏,成膜材料需要加热溶解,耗时较长。
CN103006923A专利公开了一种中药液体创可贴,其原料组成为:三叶青提取物1-3,壳聚糖1.5,乙醇10,甘油0.5,双氧水0.5,薄荷脑3,纯化水30,医用级氮酮0.5%。其存在的缺点在于不仅需将三叶青块根进行复杂的提纯处理,历时8小时以上,而且其合成创可贴的工艺需加热,降温等操作复杂,且该创可贴不防水。
发明内容
本发明的目的在于提供一种防水,透气性好,消炎止痛效果好,不会出现红肿痒等现象,且制备方法简单的液体创可贴。
本发明液体创可贴:
原料按重量比:
乙醇 60-80
樟脑 0.5-3
苯甲醇 0.1-2
三七提取液 1-5
金缕梅提取液 1-5
聚氨酯-35 15.6-30。
其中乙醇为质量浓度为95%以上的乙醇,为食品级;
樟脑、苯甲醇、三七提取液(三七总皂苷≥0.4%)为药用级原料;
金缕梅提取液(活性物含量≥3.0)、聚氨酯-35均为化妆品级原料。
本发明液体创可贴制备方法:
(1)将乙醇60-80、樟脑0.5-3、苯甲醇0.1-2、三七提取液1-5、金缕梅提取液1-5混合搅拌均匀,再加入聚氨酯-35 为15.6-30搅拌均匀,得产品。
本发明制备工艺简单,无需加热,搅拌均匀即可。
本发明采用聚氨酯-35为成膜剂,其独特的分子量特性决定它能快速成膜,且能形成防水性能好,透气的薄膜,还能给皮肤表面自然的感觉,肤感不油腻,不发沾,其硬度与弹性达到完美平衡,不紧绷,并且其附着力适中,透气,不易脱落。
本发明添加苯甲醇,具有止痛作用。并且苯甲醇具有强的极性,能够与聚氨酯很好的相容,不会出现迁移的现象。而且苯甲醇具有很好的疏水性能,能够显著提高膜的光泽。也能够提高膜的韧性,起到增塑作用。所以苯甲醇与聚氨酯-35二者协调作用,使成膜效果更好。
樟脑具有通关窍、利滞气、辟秽浊、杀虫止痒、消肿止痛。
三七提取液止血而不留瘀,对出血症兼有瘀滞者尤为适宜。其含有的止血活性成分,有L-型和D-型两种构型。此外,三七提取液中的钙离子和槲皮苷等物质亦是止血的活性物质。当机体处于出血状态时,三七提取液表现出较强的止血作用。
金缕梅提取液内含多种单宁质如Ellagtannin和Hamamlitannin等,促进淋巴血液循环,具有消炎,愈合伤口的功效。
本发明添加三七提取液,金缕梅提取液,樟脑,苯甲醇,四者协调作用,金缕梅提取液不仅具有消炎作用,其促进淋巴血液循环的同时也使三七提取液,以及樟脑,苯甲醇更好吸收,使创可贴可快速止痛,消炎,消肿,促进伤口愈合,提高疗效。

产品性能检测:
一、理化指标:
1.成膜性能:将液体创可贴取若干量倾倒在表面皿上,使其自然均匀的流布整个表面皿,厚度约为2mm,膜能揭起时,记录时间。
2.膜拉伸强度测试:将液体创可贴在标准条件下放置至少2h,然后用直尺在样品上划好两条间距25mm的平行标线,并用厚度计测出试件中间和两端三点的厚度,取其算术平均值作为试样厚度,装在拉伸试验机夹具之间,夹具间标距为70mm,以500mm/min拉伸速度拉伸试件至断裂,记录度伯断裂时的最大荷载,并量取此时试件标线间距离(L1),精确至0.1mm,测试5个试件,若有试件断裂在标线外,其结果无效,应采用备用件补做。拉伸强度的确定:拉伸强度是试样拉伸至断裂过程的最大应力。
计算式如下:P=F/S
式中:P---拉伸强度,MPa
F---试件最大荷载,N
S----试件断面面积,mm2
3.硬度测试:将液体创可贴制成厚度为2MM薄膜,平均分成形状大小相等的六块,折叠在一起,用邵氏硬度计在样板上取七个点进行测试,将测得的数据去掉一个最大值和一个最小值,其它数据取平均值为所测的硬度数据。
4.干湿摩擦牢度测试:用裁刀在液体创可贴厚度为2mm薄膜上裁取两块尺寸为200mm*50mm的干净、平整、无褶皱、无破损的样品。一块用于干摩擦,一块用于湿摩擦,将样品装置在摩擦色牢度试验机的摩擦平台上,并保持样品表面平整。设定试验机的负荷为9N,摩擦头为原型摩擦头,摩擦速度为60次/分钟,摩擦次数为10次。
干摩擦:将白色标准棉布(干)夹在摩擦杆的摩擦头上,放下支撑杆,往返摩擦30次。
湿摩擦:将白色标准棉布泡在蒸馏水中,然后经过压轧,使棉布的吸水率控制在95-105%之间。在压轧好的标准棉布(湿)套在摩擦杆的摩擦头上,放下支撑杆,往返摩擦30次。
根据牢度对照卡,读出牢度级数,一般为5级制,1至5级,1级最差,5级最好。
5.水蒸气透过率测试:取液体创可贴样品约2g,流延平铺,自然干燥,制备成薄膜(约50*50mm),按YY/T 0471.2-2004接触性创面敷料试验方法水蒸气透过率操作测试。
