Triethanolamine (TEA) is a common ingredient in skincare products that acts as an emulsifier, pH adjuster, stabilizer, surfactant, and thickener. It helps stabilize and balance the pH of a product, emulsifies immiscible fluids, and thickens the formula. While it offers no direct benefits to the skin, it plays a crucial role in the overall performance and longevity of skincare products.
Triethanolamine does not provide direct benefits to the skin, but it contributes to the overall effectiveness of skincare products by: * Emulsifying: It allows oil and non-oil substances to mix and form stable emulsions, such as creams and lotions. * Stabilizing emulsions: It helps emulsions last longer and prevents them from separating. * Thickening the formula: It adds body and texture to skincare products, improving their sensory and aesthetic appeal.
Triethanolamine is generally considered safe for use on all skin types, including sensitive skin. However, some individuals may experience irritation or allergic reactions at certain concentrations, especially above 5%.
Triethanolamine is generally considered safe when used in cosmetic products at recommended levels. However, potential side effects include: * Irritation: Some individuals may experience skin irritation, especially at high concentrations. * Allergic reactions: Some individuals may develop allergic reactions to triethanolamine.
To minimize the risk of side effects: * Avoid using products containing triethanolamine if you have known allergies or sensitivities to the ingredient. * Use products containing triethanolamine as directed and avoid excessive use. * If you experience irritation or an allergic reaction, discontinue use and consult a dermatologist.
Triethanolamine is synthetically derived from ethylene oxide, which is obtained from the petroleum industry, and ammonia, which is derived from air.
The Cosmetic Ingredient Review (CIR) Expert Panel has reviewed the safety of triethanolamine and concluded that it is safe for use in cosmetic products at concentrations up to 5%.
The Environmental Working Group (EWG) has assigned triethanolamine a skin deep score of 2, indicating a low hazard potential.
Triethanolamine should not be used with N-nitrosating agents in formulations or in cosmetic products where N-nitroso compounds can be formed, as this may lead to the formation of potentially carcinogenic nitrosamines.
