Isononyl alcohol (INA) is a nine carbon primary alcohol. It is used in small amounts as fragrance in soap, hair spray, face creams, and shampoo. INA, along with 3,5,5-Trimethyl-1-hexanol, makes up the mixture sometimes referred to as isononanol.[2]

Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).

Nonyl alcohols, including isononyl alcohol, are typically produced by hydroformylation of octenes. Isomeric octenes are produced by dimerization of butenes. These alcohol mixtures are used as solvents in paints and as precursors to plasticizers.[3]
