Acid Yellow 23 Aluminum Lake is an azo dye that is potentially harmful to human health and the environment because it can have toxic effects within the body (1).

Azo dyes, including Acid Yellow 23 Aluminum Lake, are widely used in the textile, paper, food, cosmetics and even research laboratory industries. When these compounds enter the body through ingestion, they are metabolised into aromatic amines by intestinal microorganisms. A wide variety of anaerobic bacteria have the ability to cleave the azo bond to produce aromatic amines. However, this activity of reducing azo dyes is influenced by various dietary factors.
