Is red 33 vegan?

Red 33, also known as D&C Red No. 33 or Acid Red 33, is a synthetic azo dye used to impart color. It is manufactured chemically from petroleum and coal tar hydrocarbons through a multi-step organic synthesis. This coloring agent appears primarily in cosmetics and personal care products such as lipsticks, mouthwashes, toothpastes, soaps, and shampoos, as well as certain ingestible pharmaceutical products and select food items.

This ingredient receives a vegan verdict because it is entirely synthetic and contains no animal-derived components. The raw materials used in its production come from petrochemical sources rather than animal tissues or byproducts. Additionally, the standard industrial synthesis of azo dyes does not utilize animal-derived processing aids. Because Red 33 relies strictly on chemical synthesis from fossil-fuel hydrocarbons, it is completely free from animal sources.
