Triethyl Citrate
Ingredient Info
Triethyl Citrate is a clear liquid derived from citric acid that acts as a plasticizer and preservative in skincare formulations. It helps keep products flexible and stable while extending shelf life.
Benefits
- Improves product texture and spreadability
- Extends product stability and shelf life
- Helps preserve formulation integrity
Potential concerns
- Emerging research suggests potential neurotoxic concerns at high environmental exposure levels, though current cosmetic-use concentrations are considered safe by regulatory bodies
Science: The Cosmetic Ingredient Review Expert Panel (2023) confirmed safety at typical cosmetic concentrations and use levels. However, a 2025 molecular study identified potential interactions with proteins related to cell health and inflammation, warranting further investigation into long-term safety—though this represents theoretical risk rather than documented harm in cosmetic use.
