C.I. Acid Red 13

Description:

C.I. Acid Red 13, also known as Acid Red 13 or by its chemical name, is a synthetic azo dye commonly used in various applications, including textiles, food, and cosmetics. It is characterized by its bright red color, which is attributed to the presence of azo (-N=N-) functional groups in its molecular structure. This compound is soluble in water, making it suitable for use in aqueous dyeing processes. Acid Red 13 exhibits good lightfastness and stability under acidic conditions, which enhances its utility in dyeing processes. However, like many azo dyes, it may raise concerns regarding environmental and health impacts, as some azo compounds can release aromatic amines that are potentially carcinogenic. Therefore, its use is regulated in certain applications. In terms of safety, it is advisable to handle this dye with care, using appropriate personal protective equipment to avoid skin and eye contact. Overall, C.I. Acid Red 13 is a versatile dye with significant industrial relevance, but its use must be managed responsibly.

Food Red 4

CAS: 2302-96-7

Food Red 4 is a synthetic red dye that is soluble in organic solvents. It can be used as a food, drug, and cosmetic additive. The dye has been shown to have high binding constants for both metal ions and carbon nanotubes. A Langmuir adsorption isotherm was used to determine the equilibrium adsorption of this dye onto polyvinyl monomeric particles. The electron microscopic analysis showed average particle diameters of ˜1 μm. This dye has been synthesized using an azobenzene monomer and a polymer film.
