Good luck finding Calgon these days with any phosphates in it. Most seems to have gone to Zeolites instead.
In any case, laundry phosphate, in the form of STPP, is exactly the same chemical that is added in vast amounts to many processed foods (and even toothpastes). It functions to help the foods stay moist. It is about as toxic as table salt. The difference between technical grade (the kind suitable for laundry) and food grade STPP is in purity.
Dioxane is a solvent used in extraction of other compounds in research and industry. It is nowhere near as toxic as dioxin, which as a contaminant of stuff like Agent Orange is blamed for a whole variety of health issues including cancer. I wouldn't ingest any Dioxane, either, but it's important not to confuse it with Dioxin.
Also, benzene and benzoate are two entirely different things. They are about as similar in toxicity as chlorine gas and sodium chloride.
