Styrene is an organic compound with the chemical formula C 6 H 5 CH=CH 2. Its structure consists of a vinyl group as substituent on benzene. Styrene is a colorless, oily liquid, although aged samples can appear yellowish. The compound evaporates easily and has a sweet smell, although high concentrations have a less pleasant odor.
California Gov. Gavin Newsom has banned 26 potentially toxic chemicals found in many cosmetic products, adding to a 2020 law.

Castor oil and its derivatives are found in many cosmetics as it is "non-comedogenic" (does not exacerbate or contribute to acne). [3]Cerebrosides (cells from the nervous systems of cattle or swine) were once used in some high-end skin-care products to increase moisture retention and to create a smooth skin surface, [4] however the BSE controversy has put an end to this practice.
The styrene monomer (from which polystyrene is made) is a cancer suspect agent. [109] Styrene is "generally found in such low levels in consumer products that risks aren't substantial". [110] Polystyrene which is used for food contact may not contain more than 1% (0.5% for fatty foods) of styrene by weight. [111]
The Oita Plant, the main manufacturing base, supplies SDK and other chemical companies with the basic materials for making acetyl derivatives, synthetic resin, synthetic rubber, and styrene monomers. Innovative products include a new heat-resistant, transparent sheet and film that can be used in flexible displays such as electronic paper and ...
Product trade names include Novodur®, Terluran®, and Lustran (ABS); Terlux® (MABS); and Luran® (acrylonitrile styrene acrylate). [3] Styrene-butadiene block copolymer (SBC) is a thermoplastic resin that is transparent and impact-resistant. It is used to provide a high optical appearance and is mostly found in food and display packaging.
β-Nitrostyrene is a chemical precursor for slimicides and dyes. Specifically bromo-nitrostyrene is obtained upon treatment with bromine followed by partial dehydrohalogenation [2] while 2-nitrobenzaldehyde is obtained by treatment with ozone respectively.
