TAED is in all of the Vanish Oxy laundry boosters; I'd suggest the Vanish Oxi Crystal White, see the picture.
Hydrogen Peroxide can be bought from Sally's Hairdressing Supplies, there's likely to be one in your area. They call it Developer in hairdressing circles and it's usually in a white or brown 1 litre bottle.
You only need Xanthan Gum if you want to make the gel version to paint onto larger surfaces.
