Vinyl shower curtains are 100% waterproof. The sides and bottom are cut rather than sewn and eyelets are welded into the plastic. Because these curtains are made from plastic they should be wiped clean with a damp cloth and hung out to dry; they cannot be machine washed, dry cleaned, tumble dried or ironed.
Phthalates are chemicals that are added to PVC as plasticisers. They may be harmful to people and the environment. Phthalate Free PVC does not contain phthalate plasticisers.
