Magnesium hydroxide is a useful ingredient in deodorants as it helps to keep smells away.
Our skin is naturally acidic while magnesium hydroxide is alkaline, which enables it to balance out the underarm environment & counteract odour-causing bacteria on the skin's surface. The sweat we create is actually odourless but underarm bacteria thrives on it which is what results in body odour. While antiperspirants stop us sweating & starve the bacteria, natural deodorants containing magnesium hydroxide & antibacterial essential oils make the armpit area an unpleasant place for bacteria to live & feed, resulting in less odour, naturally.
