Our C9 oxo alcohol isononanol, also known as isononyl alcohol or INA for short, is an important raw material for the production of plasticizers and surfactants. As a C4-based alcohol, INA is a key component for the production of high-performance plasticizers such as diisononyl phthalate (DINP), diisononyl cyclohexanoate (DINCH), diisononyl adipate (DINA) and triisononyl trimellitate (TINTM), which all can be used in a broad range of applications. Products manufactured with INA are mainly used in the PVC industry. For example, they can be found in the automotive industry, flooring, wires and cables and in the construction industry. Given the evolving health and environmental regulations associated with downstream applications, INA is well positioned and compliant with these requirements.

With its oxo alcohol and the plasticizers made from it, Evonik has long been an important part of the global flexible PVC value chain. As part of this value chain, Evonik not only performs an important function as a reliable supplier of key raw materials for flooring, underlay or PVC roofing membranes; the business line also develops sustainable plasticizers and is actively involved in life cycle management for high-molecular-weight plasticizers, such as the universal plasticizer DINP.

The safe and durable use of products is always Evonik's top priority - globally and in close cooperation with its customers. The business line Performance Intermediates is active in numerous industrial and trade associations in Europe, Asia and North America and uses them to promote the scientifically based evaluation of its products. The associations promote dialog and act as an additional and important information channel for customers and other stakeholders.

INA is mainly used as an intermediate for the production of plastics. Our customers combine this product with other substances to make new products such as plasticizers. These are then used in commercial applications such as flooring, wires, cables and artificial leather.

A second important application is surfactants: INA-based surfactants offer superior cleaning benefits and enable manufacturers to develop environmentally friendly, biodegradable and sustainable cleaning formulation offerings. These surfactants are a sustainable choice for producers looking to replace solvents in their cleaning products and seeking multifunctional ingredients to be used in them. They demonstrate high performance in degreasing and enable the development of efficient cleaning products with fewer ingredients.

INA is produced in our state-of-the-art C4 Verbund. Isononanol is a mixture of low-branched C9 oxo alcohols and is produced by the hydroformylation of a C8-rich olefin mixture. The clear liquid is readily biodegradable.

Here you will find further product information (e.g. technical data sheet, SDS, etc.), flyer on INA.

In our C4 Verbund, we process various raw material streams such as crude-C4 or FCC C4 (Fluid Catalytic Cracking-C4) from steam crackers or refineries. The oxo alcohol isononyl alcohol is produced at our site in Marl, Germany. The transport takes place in sea-going vessels, barges, tank wagons and tank containers.
