Turpentine oil

Botanical name: Pinus roxburghii Sarg.
Family: Pinaceae

Description of the plant:

Pine trees are found in forests on the steep, and rocky terrain of the East-West Central Hilly region of Nepal around an altitude of 600 to 1,680 m. This evergreen plant grows 30 to 45 m. tall. Its flowers bloom between the month of mid-January to June, and the fruiting season falls between August and December. Resin is extracted from these pine trees, which is used to produce industrial chemicals such as turpentine oil and rosin. Resin is also known as oleoresin, gum turpentine, and turpentine balsam.

Processing Method:

Pine's resin can be collected from March to November. The resins collected from the fields are first melted in the steam. Contaminants like wood pieces, leaf litter, and soil-sand are removed from the molten resin. Then, the thoroughly cleansed resin's (100 kg) are processed through steam distillation to produce turpentine oil (20 to 25 kg).

Properties of Turpentine Oil:

Turpentine Oil is a clear liquid, which looks like pure water. Its scent is described as a peculiar warm-balsamic with refreshing odor.

Uses:

Turpentine Oil is widely used as a solvent in the production of paints, varnishes, and boot polishes. It is used in the manufacture of medicines (ointments, liniments, lotions), perfumes, synthetic camphor, pine oil, pesticides, and other products.
