Styrene (C8H8) is used to produce plastics like polystyrene. In reaction with other monomers such as acrylonitrile and/or butadiene, it is used to synthetize rubber or latex. The pharmaceutical industry and perfumeries are using small quantities of styrene as an additive in perfumes and medicine. This substance is also used in the chemical industry as a solvent to synthetize polyester resins.

Styrene effects on health
Styrene (C3H8) is a colorless or sometimes yellowish gas with a soft smell detectable from 0.15 ppm. This volatile organic compound is very harmful by inhalation and can cause irritation to the skin and eyes (R36/38). As it is flammable between 0.9 % and 6.8 % volume, styrene vapors can form explosive gaseous mixtures. It also features reprotoxic effects. The IARC* classified it as possibly carcinogenic to humans (Group 2B).
