Triethyl Citrate
Triethyl Citrate is a naturally derived ester of citric acid and ethanol produced through esterification, creating a clear, colorless, and odorless liquid with multifunctional properties in skincare formulations. This versatile ingredient serves as an emollient, antimicrobial agent, and fragrance fixative, providing lightweight moisturization while strengthening the skin barrier and reducing transepidermal water loss. Its unique mechanism of action involves enzymatic hydrolysis on the skin to release citric acid and ethanol, which lowers pH and deactivates bacterial enzymes that cause malodor. As a non-comedogenic plasticizer and solvent, it enhances product texture, improves ingredient dispersion, and stabilizes emulsions without irritating sensitive skin. This makes it invaluable in deodorants, perfumes, creams, and sunscreens targeting oil control, antimicrobial protection, and extended fragrance longevity.
