Phthalates are a family of chemical compounds primarily used to make polyvinyl chloride (PVC), or vinyl, flexible and pliant. Phthalates are used in hundreds of products in our homes, hospitals, cars and businesses. The phthalates widely selected to soften plastics are used because of their strong performance, durability and stability. Because these phthalates plasticizers are bound into the material in which they are added, they do not easily migrate out of the product or evaporate.
High Phthalates

Phthalates are the most commonly used plasticizers in the world and are categorized as high and low, depending on their molecular weight.
- High phthalates include those with 7 or more carbon atoms in their chemical backbone, which gives them increased permanency and durability. High phthalates are commonly used in PVC products such as wire and cable jacketing, flooring, wall covering, self-adhesive films, synthetic leather, coated fabrics and roofing and automobile applications. The most common types of high phthalates include diisononyl phthalate (DINP), diisodecyl phthalate (DIDP) and dipropylheptyl phthalate (DPHP).
- Low phthalates include those with 3-6 carbon atoms in their chemical backbone. Low phthalates are commonly used in medical devices, general purpose PVC, adhesives, inks and cosmetics. The most common types of low phthalates include di (2-ethylhexyl) phthalate (DEHP) and dibutyl phthalate (DBP).
High Phthalates Facts
- With more than 50 years of research, phthalates are among the most thoroughly studied family of compounds in the world and have been reviewed by multiple regulatory bodies in the United States.
- Phthalates are widely used, and yet actual exposure levels are hundreds or thousands of times below levels of concern established by regulatory authorities.
- Phthalates are the preferred plasticizer in use today because of their strong performance, cost-effectiveness and durability.
- Phthalates are not used in plastic food wraps and containers; and food packaging like takeout containers is not “coated” with phthalates.
