Acid Red 111 is a synthetic dye that belongs to the azo dye class. It is commonly used as a coloring agent in various industries, including textiles, paper, cosmetics, and inks. Here are some characteristics of Acid Red 111:
Chemical Structure: Acid Red 111 has an azo linkage, which is a chemical bond (-N=N-) formed between two nitrogen atoms. The dye molecule also contains acidic groups, such as sulfonic acid (-SO3H) or carboxylic acid (-COOH) groups. These acidic groups make it compatible with acidic dyeing and printing processes.
Color: Acid Red 111 displays a red hue. The specific shade and intensity of the color may vary depending on the concentration and application conditions.
Solubility: Acid Red 111 is water-soluble. It dissolves readily in water, which makes it suitable for dyeing aqueous solutions and materials that can absorb water.
pH Sensitivity: Acid Red 111 is an acid dye, meaning it exhibits better affinity for cationic substrates in an acidic environment. The dye molecule carries negative charges, and in low pH conditions, it forms ionic bonds with positively charged sites on the substrate, resulting in coloration.
Lightfastness: The lightfastness of Acid Red 111 may vary depending on the specific formulation and conditions of use. Azo dyes, in general, are susceptible to fading when exposed to prolonged sunlight or other sources of UV radiation.
Environmental Impact: Acid Red 111, like other synthetic dyes, can pose environmental concerns if improperly handled or disposed of. Efforts are being made to develop more sustainable and environmentally friendly alternatives to synthetic dyes.
