1、 Magnesium stearate’s Use
Magnesium stearate is capable of using as lubricant for tablet & capsule food. ※By revision dated 2017/6/23 of 「Standards and criteria for food and food additives」, Magnesium Stearate can be used FOR CAPSULE & TABLET-FORMED FOOD and CONFECTIONERY
2、Magnesium stearate’s Advantages
As a tablet & capsule food’s lubricant, compared to Sucrose Esters of Fatty Acids, Magnesium stearate has following excellent properties WITH LOWER USING DOSAGE.
＜Main properties＞
Upgraded Prevent lubricatibity moisture Good absorption & tableting consolidation
Safe Reduce substance friction (Food additives)
※Notice in use Compared to Sucrose Esters of Fatty Acids, Disintergrating time when using Magnesium Stearate is later than around 70～200sec.
