Dea-oleth-10 Phosphate

This ingredient is considered a significant red flag in cosmetic formulations. It is explicitly listed as 'Banned or found unsafe for use in cosmetics' by the EU Cosmetics Directive, citing high use restrictions and contamination concerns with ethylene oxide and 1,4-dioxane. Furthermore, the National Toxicology Program (NTP) linked topical application of diethanolamine (DEA) and related ingredients to cancer in laboratory animals, prompting the FDA to advise consumers to avoid DEA-related substances.

The Cosmetic Ingredient Review (CIR) Expert Panel has not conducted a specific safety review for DEA-OLETH-10 PHOSPHATE. However, its classification as a diethanolamine salt raises considerable safety concerns. The National Toxicology Program (NTP) reported an association between topical diethanolamine (DEA) and certain related ingredients with cancer in laboratory animals in 1998, likely due to potential residual DEA. The FDA suggests consumers avoid DEA-related ingredients. Critically, the EU Cosmetics Directive has banned or deemed DEA-OLETH-10 PHOSPHATE unsafe for cosmetic use, primarily due to severe use restrictions and potential contamination by impurities such as ethylene oxide and 1,4-dioxane.
