Triethanolamine (TEA) is an organic compound that is commonly used in skincare and cosmetic formulations as a pH adjuster, emulsifier, and surfactant. It is a clear, colorless liquid that is soluble in water and has a slightly alkaline pH.
In skincare, TEA is often used as a pH adjuster to help maintain the pH of cosmetic products within a safe and effective range. It can also help to improve the texture and stability of skincare products, making them easier to apply and more effective at delivering active ingredients to the skin.
TEA is also used as an emulsifier, which means it can help to blend oil and water-based ingredients together in cosmetic formulations. This can help to create products that have a smooth, creamy texture and that are easier to apply and absorb into the skin.
While TEA is generally considered safe for use in cosmetics and personal care products when used in accordance with industry guidelines and regulations, it can be a potential irritant to the skin, eyes, and respiratory system, especially in higher concentrations. Some studies have also suggested that prolonged exposure to TEA may have carcinogenic effects, although this has not been definitively proven.
Overall, TEA is a useful ingredient in skincare and cosmetic formulations that helps to improve the texture, stability, and efficacy of products. However, it is important to use TEA in moderation and in accordance with industry guidelines to ensure its safety and effectiveness. As with any new skincare product, it is also important to patch test new products containing TEA before using them regularly.
