What is red 33?

Red 33 is a synthetic azo dye that is commonly used in cosmetics, food products, and pharmaceuticals. It is a bright red color and is primarily used to color items such as lipstick, blush, and eyeshadow.

Despite its widespread use, Red 33 has been associated with potential health concerns. Some studies have shown that it may cause allergic reactions or skin irritation in some individuals. Additionally, the dye has been shown to have potential carcinogenic effects in animal studies, although the evidence for this in humans is limited.

Regulatory agencies such as the FDA have approved the use of Red 33 in certain products, but have set limits on its concentration and require warning labels when it is included in cosmetics. As with any synthetic dye, it is important to use products containing Red 33 with caution and be aware of any potential risks associated with its use.
