Ponceau 4R

Description:

Ponceau 4R, also known as Acid Red 18, is a synthetic azo dye commonly used in food, cosmetics, and pharmaceuticals for its vibrant red color. It is characterized by its solubility in water, which allows it to be easily incorporated into various products. The dye exhibits a strong absorption in the visible spectrum, contributing to its intense coloration. Ponceau 4R is often utilized in the food industry as a colorant, particularly in processed foods, beverages, and confectionery. However, its use is regulated in many countries due to potential health concerns, including allergic reactions and its classification as a possible carcinogen. The dye is typically stable under normal conditions but may degrade when exposed to light or extreme pH levels. In terms of safety, it is essential to adhere to regulatory guidelines regarding its concentration in consumer products to minimize any adverse effects. Overall, Ponceau 4R is a widely recognized dye with specific applications and regulatory considerations in various industries.

C.I.Acid Red 18

CAS: 2611-82-7

Acid Red 18 is an acid dye that is used as an analytical method for cellulose. It has been shown to be effective in the treatment of wastewater and infectious diseases, such as cholera and typhoid fever. Acid Red 18 is a long-term toxicant and can induce allergic symptoms at high concentrations. The optimum concentration for adsorption varies from one material to another but ranges from 0.1% to 1%. Synchronous fluorescence spectroscopy is a technique used to measure the adsorption of dye on a surface, which can be useful in nuclear DNA analysis.
