Tartaric Acid Pellets


Product portfolio on tartaric acid pellets (TAP). TAPs are highly spherical starter pellets consisting of 100 % tartaric acid. Size ranges from 100 µm to 1,000 µm. They act as a pH modifier and as carrier systems in extended release formulations of weakly basic drugs. These drugs typically show bad solubility in higher pH environment such as in the lower intestinal tract which can be enhanced by the use of TAP as a starter core.
