Polyvinylchloride (PVC) is the third most commonly produced plastic in the world and an ingredient in many sex toys, including dildos, vibrators, anal plugs, and cock rings.
This versatile plastic can be used to make hard plastic sex toys or softer sex toys (often when combined with rubber or silicone). PVC is inexpensive, so sex toys made from this man-made material are some of the most affordable on the market. However, PVC has also been criticized for its high chemical content. Some of these chemicals, including phthalates, are thought to carry health risks to humans.
