Triethanolamine
Ingredient Info
Triethanolamine (TEA) is a pH adjusting agent and surfactant used in cosmetics to balance acidity and help mix oil and water-based ingredients. It's been used in skincare and makeup formulations for decades to improve product stability and texture.
Benefits
- Neutralizes acidic ingredients to achieve optimal skin pH
- Helps create stable, uniform product textures
- Allows better mixing of different ingredient types
Potential concerns
- May cause skin irritation or sensitization in sensitive individuals
- Can form potentially harmful nitrosamines when combined with certain preservatives
- Classified as a potential carcinogen in some recent literature reviews, though regulatory bodies consider it safe at approved concentrations
Science: A 2013 expert panel safety assessment by the Cosmetic Ingredient Review concluded TEA is safe as used in cosmetics. However, a 2023 analysis of commercial products identified TEA and its derivatives as potential carcinogens present in most facial makeup cosmetics tested, highlighting the need for longer-term safety studies on cumulative exposure.
