The C9 fraction market size was valued at USD 1.5 billion in 2024 and is forecasted to grow at a CAGR of 7.5% from 2026 to 2033, reaching USD 2.8 billion by 2033. This growth is driven by the increasing demand for C9 fractions in the production of resins, adhesives, and other chemical products. In January 2025, the European market experienced a notable price increase for C9 and C10 solvents. In Germany, C10 solvent prices rose by 1.89%, primarily driven by restocking activities post-festive season. The price trend indicates a steady increase, influenced by supply constraints and consistent demand in key application sectors.
