    How many grams of dish washing liquid are we consuming every month?
    How toxic is ingesting this amount of ingredients of an average-brand of dish washing liquid people use to clean their utensils?
    Most dish washing liquids/soaps/powders have deadly poisons in it, right?

    Is there any way to estimate the average lifespan reduction due to society's use of these toxic dish washing liquid?

    Depends how well dishes are rinsed to start with.

    Whatever the risks of clean dishes are, that risk has to be offset against the risks that washing is intended to get rid of.

    We don't want our food to be served or cooked using items that have rotten food or maggots or rat faeces attached to them. It's also about protecting our food supplies. Unless you buy all your food every day you must have some food stored in or near your cooking facilities. Providing attractive bait in the form of food scraps will mean you are much more likely to have food destroying/damaging insects, vermin, moulds and bacteria in the food you've not yet cooked or eaten.

    I do not use any soap to clean my dishes but instead use very hot water and scrub them well. Just plain water will do a very good job of cleaning most dishes. I do use a steel wool pad to clean pots and pans.

    I don't think you need to worry too much. Here is an MSDS for one brand: http://gnkproducts.ca/MSDS/Sunlight%20Dish%20Liquid.pdf

    You will see if you read down that the oral LD 50 (estimated lethal dose for 50% of population exposed) is >5g/kg bodyweight. So a 70kg person would need to swallow 350g of the stuff. It is said to be moderately irritating to the stomach etc. but there s nothing at all about cumulative build-up. I would estimate you would consume only a couple of grams of this stuff per year at most, given the dilution factor in use. So I don't see that there is anything here at all to worry about.

    Wow, this is the chemical variety. It is much worse than usual dish wash soaps. We use a similar dish wash soap to rinse our laboratory glassware. I doubt an average household uses this stuff. 30% dodecylbenzene sulfonic acid.

    In normal liquid dishwash soap you will find a lot less of this stuff.

    In response to the question of how much of this stuff we actually ingest a month. My guess would be trace amounts. However if you wash in a dishwasher, you use a more aggressive detergent than if you wash by hand. But a dishwasher rinses the contents with water afterwards (most dishwashers do this), so you will find less.

    You will not suffer any noticable health effects. There will be a bigger effect if you empty the dishwasher without bending your knees, (back-problems and such).
    Growing up, i marveled at star-trek's science, and ignored the perfect society. Now, i try to ignore their science, and marvel at the society.

    Imagine, being able to create matter out of thin air, and not coming up with using drones for boarding hostile ships. Or using drones to defend your own ship. Heck, using drones to block energy attacks, counterattack or for surveillance. Unless, of course, they are nano-machines in your blood, which is a billion times more complex..

    Use an eco friendly washing up liquid. If my dishes are only lightly soiled I use hot water and a bit of lemon juice. No need for harsh chemicals really - and the fishes/oceans prefer less chemicals too.

    Lemon juice maybe added, but plain water doesn't get rid of fats that well.

    No agreed and I cook with beef dripping too so I use an eco friendly detergent most of the time. But for cups and glasses and lightly soiled plates and the cats' bowls I forgo the detergent.

    From the countless numbers of person dying from soap poisoning, washing-up liquid is clearly being consumed at toxic levels.

    The OP does raise a valid concern, however, in that we are potentally accumulating trace amounts of undesireable substances via many venues.

    Consider toothpaste. Most of them say right on the box to use only an amount the size of a pea and DO NOT SWALLOW. The types for children are clearly indicated and even then it clearly states to monitor use so there is some concern about ingestion.

    Back to the dishes. The dishes are supposed to be rinsed yet I know from experience (and personal practice) that water is scarce in many venues so washing and wiping dry is as good as it's going to get. I use an eco-friendly brand of dish soap and very little of it because I now more often allow the ambiant air to dry my dishes for me. I use very little oil or fat in cooking so many of my dishes do not require soap for every wash and I have access to lots of HOT water.

    As to how much dish soap residue each of use may consume, the number would be difficult to assess given how many people eat convenience food, much of it in it's own single use containers. My own personal hangup is that I do not care to consume food that has been resting in styrofoam containers under a heat lamp for any length of time. I'll take dish soap over that option, any day.

    I think the risk from swallowing toothpaste is no more than mild diarrhoea (caused by the detergents).

    Not sure why the thread is just about dish washing liquid; things like shampoo, liquid handwash and shower gel are basically the same sort of stuff.

    True. I gather that plasticizers leaking into the environment are a potentially serious problem for us and wildlife.

    Swallowing toothpaste = ingesting fluoride.

    I heard before people saying about the dangers from this small amount onto the pineal gland!

    The amount of fluoride you would get from the tiny amount of toothpaste you might swallow occasionally is probably less than you get from your diet.

    I think you can ignore that sort of crackpottery.

    I wash plates and stuff like that with soap, but I clean all my frying pans with a plastic scouring brush and boiling water... Then instead of drying them I toss them back onto the stove and blast them on high for a couple minutes to dry them off/sterilize them. More or less what they recommend for Cast Iron anyway, don't see why it would make any difference for stainless steel.
