Q1: What is the primary function of Dow Triethanolamine in personal care formulations?
A: Dow Triethanolamine is commonly used as a pH adjuster and stabilizer in personal care products such as shampoos, liquid soaps, and lotions. It helps neutralize acidic components (e.g., fatty acids or alkyl sulfates) to form stable, water-soluble salts while contributing to viscosity control and mildness.
Q2: Is Dow Triethanolamine compatible with anionic surfactants?
A: Yes, it is widely used to neutralize and solubilize anionic surfactants—particularly fatty acids and sulfate-based systems—enhancing foaming, clarity, and formulation stability. Compatibility should be confirmed empirically in complex multi-component systems.
Q3: How does Dow Triethanolamine compare to monoethanolamine (MEA) or diethanolamine (DEA) in terms of irritation potential?
A: Triethanolamine generally exhibits lower skin and eye irritation potential than MEA and DEA due to its higher molecular weight, reduced volatility, and weaker basicity. However, final product safety depends on overall formulation, concentration, and exposure conditions—not solely on the amine type.
Q4: Can Dow Triethanolamine be used in industrial cleaning applications?
A: Yes, it serves as an effective corrosion inhibitor, chelating agent, and alkalinity booster in heavy-duty cleaners and metalworking fluids. Its ability to buffer pH and sequester metal ions contributes to improved cleaning efficiency and equipment protection.
