Understanding the intrinsic properties and safety of chemical ingredients is fundamental for any industry that utilizes them. Triethyl Citrate (TEC), a widely used ester of citric acid, possesses a unique set of characteristics that make it highly valuable across diverse applications, from food and pharmaceuticals to cosmetics and plastics. NINGBO INNO PHARMCHEM CO., LTD. delves into the science behind Triethyl Citrate, examining its properties and safety profile.

Triethyl Citrate (CAS 77-93-0) is chemically defined as the triester of ethanol and citric acid. Its molecular formula is C12H20O7, with a molecular weight of 276.28 g/mol. Physically, it is described as a colorless, odorless, and transparent liquid. This physical state and lack of odor contribute to its ease of use and broad applicability, as it does not impart unwanted smells or visual disturbances to formulations.

One of the key properties of Triethyl Citrate is its solubility. It is soluble in most organic solvents but only slightly soluble in oils. This characteristic dictates its utility in various formulations, particularly where a good balance of hydrophilic and lipophilic properties is required. Its relatively high boiling point and low volatility also contribute to its stability in various processing conditions.

From a safety perspective, Triethyl Citrate is highly regarded. It is classified as a non-toxic plasticizer and is readily biodegradable. Regulatory bodies worldwide have affirmed its safety for use in food (as E1505) and have also approved its use in cosmetic and pharmaceutical applications. Scientific reviews, such as those conducted by the Cosmetic Ingredient Review (CIR) Expert Panel, have concluded that Triethyl Citrate is safe for use in cosmetics and personal care products at current concentrations. Its low potential for irritation or sensitization further reinforces its favorable safety profile.

The compound’s function as a plasticizer stems from its ability to reduce the intermolecular forces between polymer chains, thereby increasing flexibility and reducing brittleness. This mechanism is crucial in applications involving plastics like PVC, as well as in pharmaceutical coatings and cosmetic films. When considering the purchase of Triethyl Citrate, understanding these scientific underpinnings helps in appreciating its efficacy.

NINGBO INNO PHARMCHEM CO., LTD. emphasizes the importance of quality and purity when supplying Triethyl Citrate. Adherence to strict quality control measures ensures that the product meets the specifications required for its diverse applications. The blend of beneficial chemical properties and a strong safety record makes Triethyl Citrate a reliable and preferred ingredient for formulators seeking effective and safe solutions.
