Description

(2-Hydroxyethyl)Ammonium Dihydrogen Citrate is an organic salt derived from citric acid and ethanolamine, offering a unique combination of buffering, chelating, and mild acidity. This compound is valued for its water solubility and compatibility in formulations requiring precise pH control and metal ion sequestration. It serves as a key intermediate and functional additive for industries including personal care, pharmaceuticals, and industrial cleaning.

Application

• Personal Care & Cosmetics: Acts as a pH adjuster, buffering agent, and mild preservative booster in creams, lotions, and hair care products.
• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) and as an excipient in controlled-release formulations.
• Industrial Cleaning & Detergents: Functions as a biodegradable chelating agent to control water hardness and enhance surfactant performance.
• Food & Beverage Processing: Employed as an acidity regulator and sequestrant in certain food-grade applications (subject to specific grade and regulatory approval).
• Metal Surface Treatment: Serves in mild pickling and cleaning solutions for metals, helping to remove oxides without excessive corrosion.
• Laboratory & Research: Utilized as a biochemical buffer component in various analytical and research protocols.
