Acetyl Tributyl Citrate

What is Acetyl Tributyl Citrate?

Acetyl Tributyl Citrate is a synthetic, colorless liquid ester produced by reacting citric acid with butyl alcohol. It functions primarily as a plasticizer and film former in cosmetic products such as nail coatings, hair styling sprays, and fragranced formulations. By softening rigid polymers, it imparts flexibility to films, minimizing cracks and improving spreadability on skin or hair. This enhances product durability, water resistance, and smooth texture. As a masking and fragrance component, it neutralizes off-odors and stabilizes sensory profiles without introducing strong scents of its own. Widely adopted as a phthalate alternative, it supports clear, stable finishes in personal care items, drawing from its chemical stability and compatibility with various bases.

Film former

Creates a continuous film on skin or hair to improve wear, water resistance, transfer resistance, shine, or hold in sunscreens, makeup, and styling products.

Masking

Reduces perception of unpleasant odors or tastes by neutralizing them or covering them with more acceptable sensory notes.

Benefits

Enhances flexibility in nail and hair films to prevent cracking and improve application.
