Triethanolamine

Description

Triethanolamine (TEA) is a versatile organic compound widely used in skincare and cosmetic formulations. This clear, viscous liquid with a mild ammonia-like odor serves multiple purposes in product development. Primarily, TEA functions as a pH adjuster, helping to balance the acidity or alkalinity of skincare products to ensure they are compatible with skin's natural pH.

In addition to its pH-regulating properties, TEA acts as an emulsifier, facilitating the stable mixing of oil and water-based ingredients in creams and lotions. It also exhibits surfactant properties, aiding in the removal of dirt and oil from the skin. TEA can enhance the foaming capabilities of cleansers and contribute to a smoother texture in various formulations.

While effective, TEA usage is regulated due to potential skin irritation and sensitization in some individuals, particularly at higher concentrations. It's crucial to note that TEA can react with nitrites, potentially forming nitrosamines, which are carcinogenic compounds. Therefore, formulators must ensure proper preservation and avoid combining TEA with nitrite-containing ingredients. Despite these considerations, when used appropriately and within recommended concentrations, triethanolamine remains a valuable ingredient in skincare product development.
