What Does Oleoresin Mean?

Oleoresin is a naturally occurring resin and oil mixture obtained from different types of plants, such as the balsam fir and pine.

This type of resin is considered to be of the soft variety and may contain cinnamic acid and benzoic acid, and referred to as balsams. Rosin derived from oleorosin is also used to inhibit corrosion in materials such as carbon steel.


Corrosionpedia Explains Oleoresin

Resin can be considered any liquid component that can turn into enamel or hard lacquer finish. Resins that are generated by the majority of plants can be described as viscous and mainly composed of volatile liquid terpenes with non-volatile, dissolved solids as constituents that make the resin sticky and thick.

Oleoresin, usually derived from pine plants, produces rosin which is an amber yellow, brittle, hard and translucent resin that is produced after distilling the oil derived from the oleoresin. In industry, rosin is mainly utilized in the following:

  • Soap
  • Buffers and sealers
  • Soldering compounds
  • Adhesives
  • Varnishes
  • Inks for printing
  • Paint driers
  • Food coloring
