Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Tributyl Citrate, as an ester of citric acid, is safe for use in cosmetics at concentrations typically found in personal care products. The European Union also classifies this substance as safe, without specific concentration regulations. While the FDA permits its use as an indirect food additive and lists citric acid esters as Generally Recognized As Safe (GRAS), it is important to acknowledge that Typology lists it as a 'suspected endocrine disruptor'.
