Quick Summary

Phthalates are salts or esters of phthalic acid, primarily used as plasticizers and solvents. Phthalic acid itself is an organic compound, and its anhydride is a key ingredient in polyesters like alkyd resins, as well as in simple esters that soften polyvinyl chloride (PVC) and other polymers.12

PVC is a widely produced plastic used in numerous products, from raincoats to window frames. It can be manufactured in a rigid or a flexible, plasticized form. Plasticized PVC, often containing significant amounts of plasticizers like di-2-ethylhexyl phthalate (DEHP), is common in items such as floor tiles, garden hoses, and upholstery.3

Concerns have been raised about potential health effects from substances like residual vinyl chloride monomer, hydrogen chloride, organometallic stabilizers, and phthalate plasticizers found in PVC products. Phthalates are also classified as endocrine disruptors, meaning they can interfere with the normal functions of hormones in the body.34
