E1505 - Citrate de triéthyle

Origin

Triethyl citrate is a synthetic ester of citric acid and ethanol. It is produced by the esterification of citric acid with ethanol. It's a colorless, odorless, and non-toxic liquid at room temperature.

Usage

Triethyl citrate is primarily used as a plasticizer, especially in the production of food packaging films and coatings. It improves the flexibility and workability of polymers. In the food industry, it is used as a flavor enhancer and as a foam stabilizer, particularly in egg white products. It is also found in some pharmaceutical coatings and cosmetic products, such as nail polish and hairspray, where it acts as a plasticizer and film former. The acceptable daily intake (ADI) has not been specified by JECFA, indicating a low level of concern regarding its safety at typical usage levels.

Side Effects

Triethyl citrate is generally considered safe for use in food and cosmetic applications. It is readily metabolized in the body to ethanol and citric acid, both of which are natural components of metabolic pathways. No significant adverse effects have been reported in human studies at typical exposure levels. However, as with any food additive, some individuals may experience mild gastrointestinal discomfort if consumed in very large quantities. Skin irritation is possible in sensitive individuals upon direct contact, but this is rare.

Regulatory Status

Triethyl citrate is approved for use as a food additive in the European Union (E1505). It is also generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use in food contact applications under specific conditions. It is also permitted for use in cosmetics and pharmaceuticals in many countries, subject to local regulations.
