Character:
The product is white without fine sand; Slightly smelly.
This product is insoluble in water, ethanol or ether.
Category:
Pharmaceutical excipients, lubricants.
Purpose:
This product is mainly used as anti slip agent or anti viscosity agent for tablets and capsules, with a general concentration of 0.25 ~ 2.0%. Due to its nitrate water property, it can delay the dissolution rate of solid preparations. Therefore, it is required to use it together with drugs with incompatibility.
Packaging:
The pearlescent film outer bag is lined with polyethylene film bag, and the net weight is 10kg / bag
Storage: sealed storage.
Marking:shall indicate the model of the product, the marked range of particle size distribution and the marked value of specific surface area.
Note: This product has a greasy feeling in contact with the skin.
Magnesium stearate has good adhesion and lubricity to skin. It can be used in powder products in cosmetics to improve adhesion and lubricity. Magnesium stearate can be used as heat stabilizer of PVC, and its stability is similar to that of calcium stearate. It can be used in food packaging materials with zinc soap or calcium soap, but it is not widely used.
