Sodium starch glycolate
VIVASTAR® & EXPLOTAB® are superdistintegrants made from potato starch by carboxymethylation and crosslinking for tablets and other oral solid dosage forms. Their unique combination of performance and cost-effectiveness has established them as globally recognized and widely used products in the pharmaceutical industry.
VIVASTAR® & EXPLOTAB® demonstrate strong swelling properties upon contact with water and other media. These highly pure excipients retain their spheroid structure to promote good flow, contain little sodium chloride or ethanol, and have high brightness.
VIVASTAR® & EXPLOTAB® offer:
Good flowability and mixing properties
Specialty grades
Strong swelling properties
