How to Use Milk of Magnesia Deodorant


The use of Milk of magnesia deodorant is increasingly popular and has since given birth to the concept of MoM deodorants such as the one by People’s Pharmacy. This article will explore this topic more closely and includes a MoM recipe as well as reviews from users of commercial products in this category.

How to Use Milk of Magnesia as Deodorant

Before we highlight how to use milk of magnesia as deodorant for excessive sweating, let us first of all the concerns about safety. Milk of magnesia is mainly magnesium hydroxide suspended in purified water, with a little sodium hypochlorite added.

A little milk of magnesia can work as a natural deodorant for you.

A research conducted in 1981 by Stewart and Downing showed that milk of magnesia (magnesium hydroxide) helped to break down wax esters and steryl esters from the human skin oil. This gave rise to the idea of using milk of magnesia for oily skin reduction and as a primer for makeup.

Opponents of this remedy however expressed concern about the high alkalinity of magnesium hydroxide (10.5) which may neutralize the film of acidic substances found on the skin, called acid mantle, which helps to maintain optimum pH for beneficial bacteria and prevent a proliferation of harmful bacteria.

When the acid mantle is neutralized from long term use of milk of magnesia on the skin, harmful bacteria may proliferate on the skin leading to numerous health problems including acne breakouts.

This then brings us to the concern about using milk of magnesia as a deodorant; a suggestion that sounds downright counterproductive. Well, there is a balancing action involved. The underarm tends to get very sweaty and moist which creates an environment that is ideal for bacterial and fungal action. While the increase in pH from the use of milk of magnesia deodorant could encourage bacterial and fungi growth and action, the resulting reduction of sweat balances this effect out.

Now going back to our topic of discussion, i.e. how to use milk of magnesia as deodorant, you basically have two options. The first is to prepare your own deodorant at home and the second one is to get one of those commercial products that are popping up on the market every day. These two potions are discussed in more details in other sections of this article.

Milk of Magnesia Deodorant Recipe and Ingredients

Milk of magnesia has long been used in Cuba to curb armpit odor and the rest of the world has since caught up to its effectiveness. We spent some time looking for a milk of magnesia recipe and here is what we came up with:

Philips milk of magnesia has many uses
Philips milk of magnesia has many uses and is found in antiperspirant deodorant recipes.

Ingredients and items needed:

  • A bottle of milk of magnesia e.g. Phillips
  • Cotton balls


  1. Pour some milk of magnesia into the lid
  2. Pour a nickel sized amount of milk of magnesia into your palm
  3. Apply it to your armpits using your fingers
  4. Allow it time to dry off before wearing your shirt. Some people suggest using a blow dryer to blast some heat on to the milk to make it dry quicker but that is up to you to decide.
  5. Discard the milk remaining in the lid

One major downside to this natural home remedy is that it takes a bit longer for the milk of magnesia to dry compared to commercial deodorants.

Whether this is really a natural deodorant is also subject to differing opinions but this is reportedly such an effective and popular option that the People’s Pharmacy decided to create a commercial deodorant with magnesium hydroxide as the active ingredient.

Keep in mind also that this milk of magnesia recipe so to speak is a deodorant and not an antiperspirant. That means that it will help to keep odor at bay but will not prevent sweating. In addition to your milk of magnesia, you may want to rub a little baking soda or baby powder to address this shortcoming.
