Its most important end use is in the production of unsaturated polyester resins that, in turn, go into items that affect our daily lives, like water tanks, or our leisure time, like sailing boats. It can also be used as plasticizer, surface active agent, emulsifying agent and demulsifying agent, mould inhibitor, antiseptic for fruit, ice inhibitor and moisture preserving agent for tobacco.
