Turpentine oil

-

Turpentine oil also known as turpentine purified and formerly French turpentine - colorless, mobile and volatile liquid with characteristic pine odor and boiling point 150-160 ° C. Produced from balsamic turpentine by single or double rectification. From ordinary turpentine there is a greater volatility and above all purity - plain balsamic turpentine, especially produced by extraction methods, contains a number of non-volatile substances, after evaporation forming a smeary, slowly drying residue.

Turpentine oil has similar properties as turpentine, but due to its higher price and more difficult availability it is rarely used, mainly for artistic and pharmaceutical purposes. It is much better solvent for making varnish than turpentine, it is also used in image preservation as a cleaner, solvent and neutral medium.

In medicine today it is almost exclusively used for rubbing; Previously, it had a wide application in the production of ointments, cataplasm, etc. external medicines.

Turpentine oil vapors, like turpentine, have a poor psychoactive effect and may be detrimental to health (kidney, liver and central nervous system damage).

Turpentine oil should be stored in sealed dark-glass vessels, and with prolonged storage - in total darkness, due to the tendency of most terpenes (which are mixtures) to polymerize and / or oxidize under light; resulting polyterpene and alcohols significantly deteriorate the quality of the oil and even prevent it from being used, for example for conservation purposes.
