DEHP Fact Sheet
Di (2-ethylhexyl) phthalate (DEHP)
TURI created these fact sheets to build understanding about toxic chemical use and health and environmental effects, as well as the availability of safer alternatives. Since Massachusetts companies report usage under the Toxics Use Reduction Act, readers will learn how the chemicals are being used and by which companies.
Di (2-ethylhexyl) phthalate (DEHP) is the international standard plasticizer for otherwise rigid plastics such as polyvinyl chloride (PVC). DEHP provides excellent flexibility at reasonable cost, and is found in a multitude of industrial, commercial and consumer products.
Properties of other plasticizers are usually reported relative to those of DEHP. However, concerns about the human and environmental health impacts associated with the use and exposure to DEHP exist. Thus the adoption of safer alternatives that provide comparable properties should be considered where possible.
