Chrisstinis, thanks for your input. I think you want to be careful to not make your CDH too strong though, because the stronger it gets the faster it breaks itself down. Eventually it will basically reach a balance where it will maintain it's CLO2 at a fairly high level, but there won't be any more SC left in it to continue activating in the stomach. If you make it according to the 4% HCl recipe which produces around 3000 ppm of CLO2, it will be plenty strong AND also be able to activate in the stomach too for at least 2 weeks. After that time the SC will gradually basically get burned up by the hot CLO2 solution, but the 3000 ppm will remain for at least a month. I found a bottle in my fridge the other day which had been there for at least a year and it was still very yellow indicating a high amount of CLO2 still in the solution. By the way, DO NOT use the caps that have the silicon rubber inserts. They gradually melt in the presence of CLO2 and then will drip into your CDH solution if they're on long enough (like 3 to 6 months). They even smell bad and also they are difficult to unscrew because they basically become sticky as the silicon melts. The best caps have a fairly stiff plastic disk type of seal insert in the caps. They are usually clear, opaque or slightly blue and they are not rubbery feeling at all. These seem to last at least a year, maybe longer. CLO2 probably know better than I do how long they last.
One last thing, I've been brushing my teeth 2 times a day with CDH for about 2 or 3 years now and also sniffing it up into my nose twice a day. I have used about 2ml in 100ml of water but now I think the right amount is actually just 0.5ml per 100ml of water which produces about 15ppm. I don't think it has to be any stronger than this to do the job and at that concentration, it doesn't have to be flavored because it's almost tasteless. Also if it's too strong, I think it can actually damage the sensitive mucus membrane - especially in the nostrils. Similar to using hydrogen peroxide on a wound. To much, to long can actually do damage and when purifying the worst water, they only use 2ppm of CLO2 to do the job. So I feel that 15ppm should be plenty - so that's just a half a drop per brushing! That's an extremely economical way to thoroughly clean your mouth and nose while you're at it.
