Violet 2 is water-soluble and produces a deep purple-violet color even at very low concentrations. It is very stable and can be used in the formulation of a wide variety of products and formulation systems. Certifiable color additive, such as Ext. Violet 2, are used widely because their coloring ability is more intense than most colors derived from natural products; thus, they are often added in smaller quantities.

Certifiable color additives generally do not impart undesirable odors or flavors while color derived from foods such as beets and cranberries can produce such unintended effects.
