General Description |
1-[(dimethylphenyl)azo]-2-naphthol, also known as Sudan I, is a synthetic azo dye that is commonly used in industrial and consumer products such as plastics, textiles, and food coloring. It is a red-orange powder with poor solubility in water but high solubility in organic solvents. Sudan I has been found to be carcinogenic and mutagenic, and is considered a health hazard when ingested, inhaled, or in contact with the skin. It has been banned or restricted in many countries, and there have been numerous cases of food contamination and product recalls associated with its presence. Consequently, there is a growing effort to replace Sudan I with safer alternatives in various industries. |
