Application

●High-efficiency Tablet Disintegrant: Can make all excipients swell at the fastest speed: effective in wet or dry granulation and direct tableting process; can be added before or after granulation, and its swelling effect and disintegration time are not affected by wetting and drying.

●Suspension Stabilizer: Reduces the particle sedimentation rate, increases the volume of the sedimentation layer, and improves the ability of sediment to be redispersed, suitable for instant dispersible and ready-to-drink dispersible dosage forms.

●Filter Aid: Can be stably combined with tannins and polyphenols, and is used for the clarification and purification of plant drug extracts.
