Carnauba wax is considered among the hardest of natural waxes. It has a high melting point, enhances oil retention, produces a very durable film, is valued as a stable co-emulsifying agent and serves as an exceptional polishing aid.
Carnauba Wax is obtained from the leaves of the Brazilian palm tree known as ‘Copernica Cerifera’, also referred to as the "Tree of Life". The Carnauba palm flourishes in northeastern regions within Brazil, and proliferates naturally along riverbanks, streams and damp low-lands.

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。
