What is 2-ethylhexanol?
2-Ethylhexanol (CAS 104-76-7), also known as isooctyl alcohol, is a branched-chain fatty alcohol used as a solvent, plasticizer precursor, and chemical intermediate. FEMA 3151.
Where is 2-ethylhexanol used?
- Plasticizers: building block for dioctyl phthalate (DOP), other plasticizers, and acrylate esters for coatings and adhesives
- Plastics processing: reacts with phthalic anhydride or adipic acid to soften PVC in flexible films, cables, and flooring
- Coatings and adhesives: 2-ethylhexyl acrylate controls film flexibility and tack in pressure-sensitive and architectural coatings
- Metalworking and lubricants: coupling solvent and intermediate for antiwear additive synthesis
- In fragrance compositions and emollient systems it serves as a low-volatility solvent and carrier.
Commercial specifications
- Clear liquid in drums, IBCs, and bulk tanker quantities
- Food and flavor grade conforming to required standards for fragrance and flavor carrier applications
