Triethyl Citrate (TEC) – CAS No. 77-93-0
Triethyl Citrate (TEC), with CAS Number 77-93-0, is a versatile, colorless, and odorless liquid ester derived from citric acid. It serves as a high-performance plasticizer, solvent, and stabilizer in various industrial applications. Known for its excellent compatibility with polymers like PVC, cellulose acetate, and nitrocellulose, TEC provides superior flexibility, durability, and resistance to migration without compromising safety or environmental standards. As a bio-based compound, it aligns with sustainable manufacturing practices, offering a non-toxic alternative to traditional phthalate plasticizers.
TEC is widely recognized for its role in enhancing product performance while meeting regulatory requirements for food contact, pharmaceuticals, and cosmetics. Its low volatility and high flash point make it ideal for heat-sensitive processes.

Frequently Asked Questions (FAQs)-Triethyl Citrate(TEC) CAS No.77-93-0
What is Triethyl Citrate (TEC)?
Triethyl Citrate (TEC), CAS 77-93-0, is the triethyl ester of citric acid, functioning primarily as a plasticizer and solvent. It is a clear, viscous liquid with low toxicity and high solvency power.
Is TEC safe for food contact applications?
Yes, TEC is FDA-approved (21 CFR 175.300) and EU-listed (E1505) for indirect food contact. It is non-migrating and does not impart odor or taste, making it suitable for packaging and processing aids.
How does TEC compare to other plasticizers like DEHP?
Unlike DEHP, TEC is phthalate-free, biodegradable, and derived from renewable sources. It offers comparable flexibility but with better thermal stability and regulatory compliance for sensitive uses.
What is the typical purity level of your TEC product?
Our standard TEC grade achieves ≥99.0% purity via gas chromatography, ensuring minimal impurities for high-end applications. Lower grades are available for cost-sensitive projects.
Can TEC be used in pharmaceutical formulations?
Absolutely. TEC is GRAS-listed and compliant with USP/NF monographs, serving as a safe excipient for tablets, capsules, and liquid dosage forms to improve solubility and stability.
What packaging options do you offer for TEC?
TEC is supplied in 200 kg steel drums, 1000 kg IBC totes, or bulk tankers. We accommodate custom sizes and UN-approved containers for global shipping.
Does TEC have any environmental benefits?
Yes, as a citrate-based ester, TEC is readily biodegradable (OECD 301B >60% in 28 days) and derived from natural citric acid, supporting sustainable production and reducing reliance on petroleum-based alternatives.
