Paraffin Wax
Paraffin Wax, NF
Strahl & Pitsch offers an extensive range of the finest food-grade Paraffin waxes from domestic and international sources. Paraffin waxes come from the de-waxing of paraffin distillates. Paraffin waxes have relatively large, brittle crystals (Macro crystalline) and generally have little affinity for oil.

先喷蜡,会在表面形成一层油层,如果是水溶性包衣,会导致包衣液接触角变小,包衣液不容易上,而且包的时间会很长,可以试着这样考虑,在油上浇层水,水会溶吗如果是油性包衣,会造成包衣不均匀,不会均匀分散,会集中在一个点散开,这和你的片型有一定关系,我想圆片子会好一点,异型的就不可以了所以比较好的选择,是放在水溶性的包衣里,与包衣材料一起放入溶解,其实巴西棕榈蜡作为包衣材料还可以促进包衣材料的溶解,因为包衣材料一般是一些高分子材料,而且也可以在搅拌过程中,产生的气泡少一点,防止喷出的液体是泡沫,这样喷出的流量才能保证.作崩解是素片的控制指标,是在压片时的,那时没有包衣,当然就没有影响了.对溶出,因为蜡的使用量是有规定的,食品添加剂上是10mg/kg,药用辅料手册暂缺,药用辅料应用技术上没有显示用量,应该不会很多,所以不会影响溶出,虽然巴西棕榈蜡能作为缓控释的骨架材料.以上意见。
石蜡(Paraffin)是从石油、页岩油或其他沥青矿物油的某些馏出物中提取出来的一种烃类混合物,主要成分是固体烷烃,无臭无味,为白色或淡黄色半透明固体。石蜡是不同分子量的正链饱和烷烃的混和物,可用通式CnH2n+2表示。按照石蜡的物理状态,可以分为液体石蜡、固体石蜡和微晶蜡三大类。石蜡具有价格低廉、来源***、无色无味、理化性能稳定、较大的相变潜热等诸多优点,因此***地应用于医药、包装、建筑、***伪装、工业和农业等领域,近年来在复合相变储能材料上有很多的研究。理化性质外观为白色固体。熔点50℃~70℃,相对密度,平均碳链长为C28~C29,相对平均分子质量为400的品种:20℃固体相对密度~,折射率~,100℃液体相对密度~,折射率~。溶于苯、氯仿、四氯化碳、樟脑油,不溶于甲醇、乙醇和水。性能指标1.熔点石蜡是烃类的混合物,因此它并不像纯化合物那样具有严格的熔点。所谓石蜡的熔点,是指在规定的条件下,冷却熔化了的石蜡试样,当冷却曲线上***次出现停滞期的温度。各种蜡制品都对石蜡要求有良好的耐温性能,即在特定温度不熔化或软化变形。按照使用条件、使用的地区和季节以及使用环境的差异,要求商品石蜡具有一系列不同的熔点。 STRAHL & PITSCH, INC. 石蜡Paraffin Wax,SP-1275, NF。
