Gum turpentine

Gum turpentine


Bambusparkett Riemen

Source and application

Gum turpentine is used both as a solvent, and also as a feedstock for the fractionation of pinene and other isomers which are used as building blocks and intermediates in the synthesis of fragrances, flavours and pharmaceutical compounds.

It is one of the few solvents in use today that is largely carbon dioxide neutral with no significant contribution to global warming. It is is produced from crude turpentine oil that is collected from pine forests by distillation. This process also yields gum rosin.

Solvent applications of gum turpentine include paints, coatings and resins. It finds use as a solvent for diluting varnishes and is traditionally used in artist�s paints and brush cleaners. The use of turpentine in place of petroleum-derived solvents is not only beneficial to the environment, but it also creates rural jobs.

The increasing demand for turpentine derivatives in the flavour and fragrance sector is placing increasing strains on supply internationally.

InterMiraxis supplies super-grade quality turpentine in isotanks or in drums.
