Acetate esters of oxo alcohols have been available to AgChem formulators outside the U.S. for several years and are being used as solvents and cosolvents in a variety of commercial product formulations. Only recently, as a result of EPA action to grant this family of products exemption from the requirement of a maximum residue limit, have these materials become available for use in the U.S. The product family consists of a homologous series of acetate esters derived from oxo-alcohols, ranging from carbon number C6 through C13.

This paper describes the composition and physical properties of these solvents. Important performance properties; such as solvency, low temperature capabilities and low/controlled volatility, which are most useful to the formulator will be highlighted and compared to those of other inerts commonly used by the industry. Since the entire family has received a tolerance exemption, the oxo-alcohol acetate group of solvents offers a high degree of flexibility to the formulator of agricultural chemical products.
