• 60g of shea butter
• 8g of beeswax pellets
• 45g of coconut oil
• 10 drops of vitamin e oil (optional)
• ~20 drops of essential oil (optional fragrance)
• 2 tablespoons of magnesium hydroxide
• 1/2 tablespoon of arrowroot powder or tapioca starch (optional absorbant) 

This makes around 4 ounces of deodorant, about enough for one person in a small jar.

Instructions – How To Make

Combine the shea butter, beeswax, and coconut oil. Melt in a double boiler on the stove. The beeswax will take the longest to melt completely.
Once melted, remove from heat, transfer into final container(s), and stir in the essential oils.
Allow to cool until the mixture is thick enough that powders will be suspended in oils rather than sink to the bottom if it is too liquid (powders do not dissolve in oil, so they will just sink if it is liquid). Then stir in powders – magnesium hydroxide and arrowroot / tapioca.

Notes & How to Use

To use, take out a pea-sized amount or so and rub it onto your armpits.

Stain Potential:

It may stain the clothes if too much is applied or depending on the fit of the clothing. Soaking in hot water before washing will help if this happens.
Modifying the recipe will change how easily it stains. Increasing the coconut oil side of the ratio will stain very quickly; substituting other ingredients may make it better or worse. Shea butter and beeswax are more waxy than oily, which may be what helps.

Ingredients:

The oils are a moisturizing and low-staining base; but they are not the key ingredient so can be substituted if desired.

Magnesium hydroxide is the key ingredient and should not be substituted. It sits on the skin instead of absorbing in, giving longevity to its effect, and is what fights the bacteria which make the foul smell. Most DIY deodorants use baking soda, but this is very hard on the skin as it is the wrong pH. 

Arrowroot powder or tapioca starch can absorb some moisture during use but is optional.

It is possible to modify this to a stick form if desired, by modifying the ratio to a much higher level of solid-at-room-temperature ingredients and using a plastic stick applicator.
