Stricter Regulations on 1,4-Dioxane in Cosmetics


Although most organisations categorize 1,4-dioxane as a suspected carcinogen, it is found in many of our products. This issue has raised the concern amongst consumers. In recent years, stricter laws on the level of 1,4-dioxane has been imposed. Other than the regulations in ASEAN and EU, New York’s governor Andrew Cuomo also signed a bill prohibiting the sale of any household cleaning products, cosmetics, and personal care products that contain 1,4-dioxane above trace concentrations.

1,4-dioxane is a by-product formed through ethoxylation and is a contaminant found in many products. It is also known as dioxane, dioxan, p-dioxane, diethylene dioxide, diethylene oxide, diethylene ether and glycol ethylene ether.

Classifications of 1,4-dioxane:
  • EU: category 2 (suspected of causing cancer).
  • International Agency for Research on Cancer (IARC): Group 2B (possibly carcinogenic to humans)
  • US Environmental Protection Agency (US EPA): Group B2 (probable human carcinogen or likely to be carcinogenic to humans)
  • Occupational Safety and Health (NIOSH): Potential occupational carcinogen
