Sodium Stearyl Fumarate

Appearance:
White to off-white powder or granule.
Almost insoluble in water, slightly soluble in methanol, insoluble in acetone and anhydrous ethanol.
Application: 
As lubricants for tablets and capsules with a concentration of 0.5 ~ 2.0% (w/w).
It can form a protective coat film in effervescent tablets.
As this product has one fatty chain less and one hydrophilic group more compared with magnesium stearate, so it can solve the slow dissolution of magnesium stearate as lubricant.
Suitable for lubricants of razole drugs, which are easy to react with magnesium stearate and cannot use magnesium stearate as lubricant.
As a regulator and stabilizer, such as baked foods, floured thickened foods, baked potatoes and processed grains, with dosage for 0.2 %~ 1.0% of the food weight.
