Hexane is a straight chain alkane and is used as an oil solvent in laboratories and as an organic solvent in industry. However, if inhaled in the case of hexane gas, it causes poisoning. As hexane is harmful to human health, it is generally used as a derivative of heptane. Heptane is also a saturated hydrocarbon which falls within the class of alkanes. Heptane dissolves oil more effectively, but it is easier to find hexane.

Naphtha is a petroleum-based solvent. Naphtha emerges from petroleum refineries as an intermediate product and contains more than one chemical substance. For example, dimethyl benzene, toluene, pentane, heptane, ethyl benzene, benzene, sulfur and N-Hexane. N-Hexane is used as solvent and viscosity enhancer. In the food industry, it is used to extract oil from oilseeds such as sunflower and soy. Crude oil is obtained from oilseed varieties used in seed oil production by first pressing and then N-Hexane extraction processes.

The European Union has banned the use of N-hexane in the cosmetics sector. Negative effects of this chemical compound on human nervous system have been determined. It has a mild drug effect even when exposed for short periods of time. Prolonged exposure may result in devastating effects. Over time, it destroys the central nervous system, weakens muscles, causes coordination problems and leads to visual disturbances. Even at low doses, the N-Hexane compound is an effective poison. Moreover, this poison effect continues after spreading to the environment. In short, it is a chemical with extremely harmful effects.

At the authorized laboratories, maximum extractable fraction determination studies are carried out in N-Hexane in the oil sector within the scope of chemical tests. In these analyzes, the standards published by domestic and foreign organizations and the analysis methods and test criteria accepted worldwide are followed and a reliable and impartial service is provided in the laboratories.
