Acetates such as  Isoamyl Acetate, and Isopropyl Acetate are highly versatile solvents. They are widely used in paints and coatings as solvents for nitrocellulose, acrylic, and polyurethane resins. They also play a key role in inks thanks to their excellent evaporation rate and strong solvency power. In cosmetics and perfumery, their mild odor and suitable volatility make them highly valued. Additionally, they serve as solvents for polymer-based adhesives. Their main advantage lies in the balance between evaporation speed and compatibility with various polymers

Most of SEQENS acetates are from a natural origin that gives rise to a low product carbon footprint in comparison to the mass produced petrochemical equivalent grades. Carbon footprint data (based on calculations independently verified by a third-party organization) are available upon request.

• Isopropyl Acetate (CAS 108-21-4) is an important solvent in the synthesis of Active Pharmaceutical Ingredients (APIs) due to its versatile solvency properties, mild odor, and low toxicity. We have developed a low carbon footprint version, neo Isopropyl acetate helps our customer to reduce their carbon footprint and achieve their sustainability targets.It can also be used in various coating formulations and in the production of flexographic inks
