Abstract
The A. studied the influence of storage conditions in regard to ten certified dyes contained in liquid pharmaceutical preparations: aqueous solution, simple and modified syrups and elixir, buffered at pH 2.0; 4.0; 6.0; 7.0 AND 8.0. The diffuse light is the most important factor in the alteration of colorants in liquid dosage forms. The room temperature had influence over the following dyes: amaranth, F.D. & C. Red n; degrees 1; F;D. & C. Blue n. degrees 2; F.D. & C. Red n. degrees 4 and F.D. & C. Violet n. degrees 1.
