Oil seed extraction  

For over 30 years, ExxonMobil Chemical has provided reliable products and solution-focused expertise to help oil seed millers meet their most demanding extraction challenges.

Exxsol™ hexane*, a widely used palm oil seed processing aid, is a complex mixture of aliphatic hydrocarbons obtained by the hydrogenation of a petroleum fraction that consists primarily of normal, isoparaffinic and cycloparaffinic C6 hydrocarbons. Exxsol hexane* can be useful for palm oil millers because of its high purity, narrow boiling range and very low benzene content.

Exxsol™ hexane SG1 meets Food and Drug Administration (FDA) requirements2 for use in specified direct and indirect food contact applications and is manufactured to meet the purity requirements of FAO/WHO/JECFA3 with respect to heavy metals, polycyclic aromatics hydrocarbons and benzene.

Applications and benefits

  • High purity
  • Very low benzene content4
  • Narrow boiling range5
  • GMP compliant
  • Meets FDA, FAO, WHO, JECFA requirements
