Why is it Nasty?
While not all polymers are nasty, some of those commonly found in dish detergents can have serious, negative effects on both human and environmental heath. The specific effects to be aware of will depend on the polymer in your product but they may include carcinogenic contaminates such as 1,4-dioxane or may be toxic to aquatic life by bioacuumulating in thier systems. Many are made from petroleum sources and thier production process results in harmful waste byproducts. Keeping synthetic polymers out of your dish soap will help to keep them out of our water systems too.
