Compare this material →This material’s published information has not yet been verified by a human reviewer.
Human verification concerns the stated information and scope. It is separate from an EcoSafe score, certification or safety approval.Isobutyl acetate is an acetate-ester solvent used in coatings, printing inks and other industrial formulations. It is a different chemical isomer from n-butyl acetate, with its own CAS number, evaporation behaviour and supplier specifications.

Isobutyl acetate provides solvent action for coating resins and is used in lacquer and ink formulations. Supplier sources also describe industrial process-solvent applications. Selection depends on the resin, drying requirements and exact grade; this profile is not a reformulation recipe.
Relevant markets include industrial, automotive and wood coatings, graphic arts/printing inks and chemical processing. The linked suppliers list examples of applications; no global market-size estimate or market-share ranking has been adopted.
There is no blanket green status. Eastman describes its isobutyl acetate as readily biodegradable and non-HAP, but those attributes do not establish zero toxicity, renewable feedstock or a complete environmental advantage. The supplied OXEA SDS classifies it as highly flammable and harmful to aquatic life. A sourcing claim needs grade-specific renewable-content and life-cycle evidence.
Highly flammable liquid and vapour (H225); may cause drowsiness or dizziness (H336); harmful to aquatic life (H402). Repeated exposure may dry or crack skin.

OXEA Isobutyl acetate: USA SDS and sales specification with separately sourced Africa/Asia dynamic viscosity. These are supplier-document values for the named OXEA product, not universal guaranteed values for every supplier. Sales limits are specifications; SDS section 9 values are substance reference data. Dynamic viscosity is from the separately identified Africa/Asia English SDS; the US SDS reports kinematic viscosity instead. The SDS heading “Density and/or relative density” has no unit, so no g/cm³ value or specific-gravity interpretation is inferred. US SDS kinematic viscosity: 0.804 mm²/s at 20 °C. Values below −90 °C are reported using DIN ISO 3016 (a pour-point method), so no equilibrium melting-point value is inferred.
