Syntetiset

Syntetiset is the Finnish term for substances and materials produced by chemical synthesis or other artificial processes, as opposed to substances occurring naturally. The category encompasses a broad range of materials, including polymers (such as polyethylene and polystyrene), synthetic fibers (nylon, polyester), coatings, dyes and pigments, as well as many chemicals used in pharmaceuticals, agriculture, and manufacturing.

In everyday and technical usage, syntetiset is contrasted with naturals or luonnontuotteet. The word derives from syntetinen (synthetic), itself from the Greek roots synthetikos meaning "put together." In industry and science, the term is used to describe products designed for specific properties through controlled synthesis, rather than extraction from natural sources.

Categories and examples include plastics, rubbers and elastomers; synthetic fibers; paints and inks; specialty chemicals; laboratory reagents; agrochemicals; and pharmaceuticals synthesized by chemical processes.

Regulation and safety: In the European Union and other jurisdictions, many syntetiset substances are subject to chemical safety regulation (for example, EU REACH) and labeling requirements. Environmental and health considerations drive research into alternative materials, recycling, and life-cycle assessment.
