How do natural deodorants work exactly?

Hi, I make natural deodorants in Tasmania, a small island off the south of Australia. They work! And i'm wondering how to explain the science of how they work better than the standard explanations like 'they neutralise odor causing bacteria' etc Do the active ingredients in natural deodorants (which may include coconut oil, shea butter, sodium bicarbonate, magnesium hydroxide, essential oils etc) actually kill the bacteria? How does the relative alkalinity/acidity of the axilla effect BO? Here's my website if you're interested and i'll send you some if you'd like to put it to the test :-) I read Mark Smith's article about your research in The Australian magazine and i found it fascinating!
