    "the human health impacts of many such chemicals remain poorly understood"

    The effects of ritual bathing (soap, scrubbing with washcloths, etc.) on the skin may also be "poorly understood". Many people also wear regularly-washed clothing.

    When I look at the laundry-list of chemicals in personal-care products (soaps, shampoos) (and in foods ... sometimes, wow!) I often wonder how much effort goes into testing all of this gunk.

    A lot of effort

    Good news (sarcasm), they laid off all the people responsible for that.

    Into testing the long-term biochemical and environmental consequences? lol no absolutely not. Source: I work in this field.

    Occasionally when I shower I get this vivid vision: a man comes home from hard days work and takes a shower. Grabs his shampoo but only squirts out half of his usual amount because shampoo bottle is empty, he thinks it will be enough but after applying it instantly feels it's not enough, so he grabs his wife's shampoo, squirts the second half and rubs it onto his hair. Few seconds later his hair bursts into fire because different chemicals in two completely different shampoos reacted together. How plausible is this scenario?

    This happened to me and the water itself caught on fire somehow

    I don't think it's very plausible for shampoo but it's relevant for toothpaste for sensitive teeth. There's are two mechanisms for sensitive teeth, one is to flood the nerve with potassium ions using potassium nitrate, i.e. saltpetre. The other method is to block access to the nerve endings with other chemicals. You could potentially mix toothpaste and get your mouth to warm up slightly.

    No worries, the stuff in the wife's bottle is the same, just more expensive.

    At least in eu, regulation is present to at least try to ensure that products are quite safe for the customers and for the environment

    Didn't the Joker contaminate personal care products so they did in a Batman movie?

    I agree. We should go back to the Roman days when clothes were washed in urine.

    I think there are no long terms and that’s the case for food as well

    Could very well happen if his wife's into Monat.

    IIRC ShyNM for Indian market for sealing holes in the enamel, warms up, unmixed of course.

    Some scin medicines contain Urea. It's not that we're much better.

    To add: urine is rich of phosphorus salts. Contained in...washing agents.

    As plausible as a leaf catching fire if it lands on a mouse.

    Maybe we should. Maybe that's better than global warming.
