A friend of mine directed me to an article they figured I might be interested and I thought to share it here too:

Five Reasons Why You Should Probably Stop Using Antibacterial Soap

The relevant section is reason no. 3:

"3. The soaps could act as endocrine disruptors. A number of studies have found that, in rats, frogs and other animals, triclosan appears to interfere with the body’s regulation of thyroid hormone, perhaps because it chemically resembles the hormone closely enough that it can bind to its receptor sites. If this is the case in humans, too, there are worries that it could lead to problems such as infertility, artificially-advanced early puberty, obesity and cancer.

These same effects haven’t yet been found in humans, but the FDA calls the animal studies “a concern”—and notes that, given the minimal benefits of long-term triclosan use, it’s likely not worth the risk."

I thought reading the above they were maybe implying that triclosan could be impairing cellular uptake of thyroid hormones, such as with cellular resistance to T3, but they linked two studies and the second one of which I read the abstract for sounded more like it decreased Serum T3 and Serum T4 concentrations (in rats at least).

I guess the point here is probably not enough is known about what Triclosan is doing and it might be worth considering cutting these out of your routine if you are a thyroid patients if in fact normal soap and water isn't likely to do much worse of a job of cleaning/sanitising our hands.

I've also read that triclosan can cause muscle problems and consequently I stopped using Colgate Total toothpastes as they all have triclosan in them. Waitrose does an antibacterial soap which has 'triclosan free' written on the front.


I've stopped using all antibacterials - hand washes, hand gels, kitchen cleaners, antibacterial washing up liquid etc. because of the dangers. I have found to have high sensitivity to the triclosan and have it in my body. With not using it and good quality vits and minerals to aid detox pathways it is reducing. My symptoms are chronic fatigue not sorted out by T3 only treatment. This is one if the toxins found to be causing problems with poor mitochondrial function, hence the fatigue. My other issues are mercury and hair dye (dianimo compounds). I didn't believe this at first but all 3 are highly toxic chemicals...

You can buy organic hand washes, soap and cleaning agents (many use tea tree oil).

Hello Mary

Can I ask if you had to have a special test to find out about your sensitivities to triclosan & if so how would I be able to access this ? I cannot use these soaps etc., because of severe dermititis and rashes so this would be very helpful to know

Thanking you



Sutton, I've sent you a private message. A good place for further general information and tests is Dr Myhill's website about toxins.



Hi all

Not only does it interfere with animals , think about what the flood of anti bacterial soaps, cleaners etc is doing to mutate the bacteria? No wonder there are more & more antibiotic resistant bugs

Soap & water do a great job so don't need to use all that other crap it's just a marketing trick to buy them
