Have you ever wondered how seemingly ordinary ingredients in everyday products deliver specific functionalities? Today we examine triethyl citrate, a chemical compound that plays multiple critical roles across various industries.

Triethyl Citrate: More Than Just an Acid Derivative

While citric acid is commonly known as a food additive, its derivative—triethyl citrate—has applications far beyond flavor enhancement. This colorless, transparent liquid boasts exceptional solubility and low volatility, making it indispensable in industrial processes.

Key Properties and Specifications

A closer examination of triethyl citrate reveals why it's so valuable:

• High Purity: Minimum 99.0% purity (verified by GC analysis) ensures reliability in precision applications.
• Packaging: Typically available in 500g units, convenient for laboratory and small-scale production use.
• Molecular Data: With the chemical formula C12H20O7 and molecular weight of 276.29, it carries CAS registry number 77-93-0 for precise identification.
• Physical Characteristics: The liquid maintains stability at low temperatures (-45°C melting point), with a refractive index of 1.44 and specific gravity of 1.14—critical parameters for formulation development.
• Stability: Marked as "n/a" for special avoidance conditions, indicating general stability though caution remains necessary with strong oxidizers or extreme pH environments.

Industrial Applications

Triethyl citrate's versatility shines through its diverse uses:

• Plasticizer: Enhances flexibility and processability in PVC products, films, and coatings.
• Solvent: Effectively carries fragrances, flavors, and pharmaceutical actives.
• Process Aid: Serves as curing agent or reaction facilitator in specialized chemical processes.
• Cosmetic Ingredient: Functions as fragrance fixative, solvent, and skin conditioning agent in personal care formulations.

Safety and Regulatory Status

Listed as "Yes" under TSCA (Toxic Substances Control Act), triethyl citrate's manufacture and use in the United States falls under regulatory oversight. While transportation hazard classifications appear unspecified in available data, proper handling protocols should always be observed per regional chemical safety standards.

This multifunctional compound demonstrates how fundamental chemicals enable advanced material performance and product innovation across industries. Understanding such substances' properties remains essential for process optimization and safe industrial practices.
