Keep your family safe and healthy with non-toxic PEVA shower liners. The greatest danger in your bathroom could be your new vinyl shower curtain. The EPA found poly vinyl chloride (PVC) products are laden with 108 volatile organic compounds and poisonous chemicals that emit toxic gas into the air which can persist for the first 28 days. PVC plastic is softened with hormone-disrupting phthalates and includes chlorine which creates dioxin, a carcinogenic chemical formed during its creation and destruction. Dioxin is dangerous since it easily penetrates the food chain of the planet as it can travel widely without breaking down.
