C.I. Acid Red 14

Description:

C.I. Acid Red 14, also known as Allura Red AC, is a synthetic azo dye commonly used in various applications, including food, cosmetics, and textiles. It is characterized by its vibrant red color, which is attributed to the presence of azo (-N=N-) functional groups in its molecular structure. This compound is water-soluble, allowing it to dissolve easily in aqueous solutions, making it suitable for use in liquid formulations. Acid Red 14 exhibits good stability under normal conditions, although it may degrade when exposed to strong light or extreme pH levels. It is important to note that while it is approved for use in many countries, some regulatory bodies have raised concerns regarding potential allergic reactions and hyperactivity in sensitive individuals, particularly in children. As with many synthetic dyes, its environmental impact and biodegradability are also considerations in its use. Overall, C.I. Acid Red 14 is a widely utilized dye with specific characteristics that make it valuable in various industries, while also necessitating careful consideration of its safety and environmental implications.

Food red 3

CAS: 3567-69-9

Food red 3 is a red dye that is used in food and beverage products to give them a reddish color. The adsorption of Food Red 3 to the surface of water droplets is an example of Langmuir adsorption. This process is reversible, as the dye can be removed by heating. This process has been shown to be toxic to bacteria in wastewater treatment systems, where it can cause cell death at high concentrations. In addition, this compound has been shown to have long-term toxicity in rats and mice when ingested, which may be due to its ability to generate reactive oxygen species.
