Description

Diethyl Citrate is a clear, colorless liquid ester derived from citric acid, widely valued for its excellent solvent properties and low toxicity. This versatile compound serves as a key intermediate and functional additive across multiple high-value industries, offering a safer alternative to more aggressive solvents. It is particularly essential for manufacturers in the pharmaceutical, food, cosmetic, and polymer sectors seeking reliable, compliant, and high-purity ingredients.

Application

• Pharmaceuticals: Used as a plasticizer in the coating of tablets and capsules, and as a solvent in topical formulations.
• Food & Beverage: Functions as a flavoring agent, emulsifier, and stabilizer in various food products and non-alcoholic beverages.
• Cosmetics & Personal Care: Acts as a solvent, fragrance fixative, and emollient in perfumes, lotions, and creams.
• Polymer Industry: Employed as a non-toxic plasticizer and crosslinking agent for cellulose acetate and other specialty resins.
• Industrial Chemistry: Serves as an intermediate in organic synthesis and as a solvent for dyes, inks, and specialty coatings.
• Adhesives & Sealants: Utilized as a coalescing agent and plasticizer to improve flexibility and adhesion properties.
