Triethanolamine is an organic compound with the chemical formula C6H15NO3. It is a tertiary amine and belongs to the ethanolamine family.
Physical Form:
Triethanolamine is commonly found as a colorless to pale yellow liquid, although it can also be in the form of a solid at room temperature.
Function and Uses:
Alkaline Agent: Triethanolamine is an amine that exhibits alkaline properties. It is often used to neutralize acidic components in cosmetic and personal care formulations.
Emulsifier: Triethanolamine is employed as an emulsifying agent, facilitating the blending of oil and water-based ingredients in cosmetic products.
pH Adjuster: Due to its ability to adjust pH, triethanolamine is used to stabilize and control the acidity or alkalinity of formulations, contributing to the overall stability of the product.
Surfactant: In addition to its emulsifying properties, triethanolamine acts as a surfactant, reducing the surface tension between different substances.
Viscosity Control: It can function as a thickening or viscosity-controlling agent in various formulations, helping to achieve the desired texture and consistency.
Common Applications:
Triethanolamine is used in a variety of cosmetic and personal care products, including creams, lotions, shampoos, soaps, and sunscreens.
Benefits:
pH Adjustment: Triethanolamine helps maintain the pH balance of cosmetic products, ensuring they fall within the desired range for stability and effectiveness.
Emulsification: Its emulsifying properties make it valuable in formulating products with both oil and water components.
Texture Enhancement: Triethanolamine contributes to the texture and feel of cosmetic products, providing a smooth and easy-to-apply consistency.
Compatibility: It is compatible with a wide range of cosmetic ingredients, making it versatile in formulating various products.
Considerations:
Triethanolamine is generally regarded as safe for use in cosmetics when used within regulatory guidelines. However, concerns have been raised about its potential to react with certain cosmetic ingredients to form nitrosamines, which are compounds with potential health risks.
Regulatory Status:
Triethanolamine is approved for use in cosmetics and personal care products by regulatory agencies. Specific usage concentrations may be regulated depending on the product type.
Usage Instructions:
Manufacturers incorporate triethanolamine into formulations at recommended concentrations to achieve the desired pH, emulsification, and viscosity control.
Product formulations should adhere to regulatory guidelines to ensure safety and efficacy.
