Acetyl Triethyl Citrate

What is Acetyl Triethyl Citrate?

Acetyl triethyl citrate is a clear, colorless liquid derived from citric acid through esterification with ethanol and acetylation. Commonly found in nail polishes, hair sprays, and scented formulations, it serves as a multifunctional additive. As a plasticizer, it softens polymer films, preventing cracking and improving spreadability during application. In film-forming products, it creates flexible, durable coatings that resist water and enhance longevity on skin or hair. For fragrances, it acts as a solvent and masking agent, stabilizing scents and neutralizing off-odors without introducing allergens. This phthalate-free option aligns with clean beauty trends, offering performance in personal care without compromising texture or hold.
