Phthalates are esters of phthalic acid, commonly referred to as plasticizers. They’re used to increase the durability and flexibility of plastics. They’re also found in a myriad of products the average person comes into contact with on a daily basis, such as wallpapers, vinyl flooring, food packaging, pharmaceuticals, plastic coated clothing, detergent, dish soap, shampoo, hairspray, makeup, and toys.
