With advances in manufacturing techniques, face masks today come in a wide variety of colors and styles—especially KF94 masks in three-dimensional or gradient designs. But while these masks are visually appealing, safety concerns have arisen over the use of azo dyes in mask fabrics.
What Are Azo Dyes—and Are They Dangerous?
Azo dyes are commonly used synthetic colorants, frequently found in textiles and clothing. While most are stable under normal conditions, some prohibited azo dyes can break down in certain environments—like high heat or high acidity—to release aromatic amines, substances classified as potential carcinogens.
In past investigations, government agencies such as Taiwan's Department of Consumer Protection have reported face masks sold online that contained banned azo dyes, raising public concern about long-term exposure risks, especially with prolonged, close contact to facial skin and respiratory pathways.
Safer Alternative: Polypropylene (PP)
Polypropylene (PP) is widely recognized as a safe, skin-friendly, and high-quality material. In face mask production, it is melted and spun into nonwoven or melt-blown fabrics, and can be colored without relying on hazardous azo dyes.
Reputable manufacturers will go a step further by providing safety test reports that confirm the materials are non-toxic, free of formaldehyde, heavy metals, and banned azo dyes.
