Main uses
This product is mainly used as tablet and capsule lubricant or anti-viscosity agent, the general concentration is 0.25-2.0%, because of its hydrophobicity, it can delay the dissolution rate of solid preparation drugs, so it requires the use of concentration as low as possible, and should avoid the use of alkaline incompatibility with drugs.
