Description

Glycine Citrate is a high-purity, pharma-grade complex of glycine and citric acid, offering a synergistic blend of amino acid and organic acid functionalities. This compound is critical for applications requiring precise buffering capacity, metal chelation, and pH stabilization in sensitive formulations. It serves as an essential raw material and intermediate for manufacturers in the pharmaceutical, nutraceutical, and high-end personal care industries seeking reliable, consistent quality for their production processes.

Application

• Pharmaceutical Buffering Agent: Used in injectable formulations, oral solutions, and effervescent tablets to maintain precise pH stability.
• Nutraceutical & Dietary Supplement Ingredient: Serves as a bioavailable mineral chelator (e.g., magnesium glycinate citrate) in mineral supplements for enhanced absorption.
• Biochemical & Cell Culture Reagent: Employed in buffer systems for protein purification, enzymatic assays, and cell culture media preparation.
• Personal Care Product Stabilizer: Acts as a pH adjuster and chelating agent in high-end skincare serums, lotions, and stabilizing cosmetic formulations.
• Food Additive & Flavor Enhancer: Used as an acidity regulator and flavor potentiator in certain food and beverage products.
• Industrial Cleaning Agent Component: Incorporated into descaling and chelating cleaning solutions where a biodegradable and effective sequestrant is required.
