General description: | Dimethyl isophthalate belongs to the class of phthalates, which are widely used as plasticizers to make hard plastics more flexible. They are utilized in a variety of products including cosmetics, detergents, lubricating oils, solvents, polychlorinated biphenyl substitutes, carriers in pesticide formulations, building products such as flooring, sheeting, films, personal care products, medical devices, food packaging and toys. Exposure to phthalates is inevitable due to its prevalence in most of the consumer products. Thus, there is continued investigation and ongoing research to determine the potential health hazards of these group of chemicals. |
General description: | This substance is listed on the positive list of the EU regulation 10/2011 for plastics intended to come into contact with food. |
