Deodorant With Zinc Ricinoleate

Deodorant With Zinc Ricinoleate


I first started making deodorant in high school, after my mom started making her own. It was the classic baking-soda based recipe that is all over the internet, and it does absolutely work. However after using it for 4 years at university (it held up through lectures, sports and sweaty nights out at the club), I developed a rash. This was due to the high pH of baking soda applied directly to skin, and also possibly irritation from the copious amounts of peppermint essential oil I used to throw in (back then little me wasn’t really concerned amount measuring, or exact formulation, or essential oil dermal limits, shame). So I stopped using it and have used a store bought deo ever since. It’s one of only two products that I don’t make for myself, the other being toothpaste.


However I’ve been meaning to experiment with  zinc ricinoleate which is a natural odour absorber, and has potential to make a great deo.


This ingredient is somewhat enigmatic, and not many formulations exist out there that use it. The supplier’s manufacturing instructions on the technical sheet are vague, but I went onto their website and found some guideline formulations. As is the case with many suppliers, their formulations are often not natural and make use of all kinds of ingredients that don’t meet our ingredients’ policy, so I end up having to just do my own experiments. Which is a good thing!


With a recommended usage rate of 1-10%, I like to start in the middle so we’re working with 5% zinc ricinoleate. You are welcome to increase this and adjust the formulas accordingly if you would like to try it at a higher percentage.

It is a water soluble ingredient, so great for liquid, water-based sprays or even roll ons, but if you wanted to make some kind of stick-deo formulation, you could simply employ an emulsifier and a bunch of waxes and thickeners to incorporate it.


I personally do prefer a spray deo and something that dries fast and isn’t sticky or oily. One of the supplier formulations made use of alcohol for its quick-drying abilities, and while I don’t want to spray alcohol on my skin, it is a key ingredient in many deodorants. However we can use witch hazel distillate (which contains some naturally occurring alcohol) in place of pure alcohol. If you don’t have witch hazel you could in theory use another hydrosol or even just plain water.


I’m using the potassium sorbate/sodium benzoate preservative system as it is a scentless powder, but feel free to use Geogard or even Saliguard SP if you prefer.

Weigh out all the ingredients and mix them together in a beaker. Test and adjust the pH down to skin levels of around 4.5-5.5 with more citric acid if required.

Pour into a spritzer bottle.


To use, spritz a few pumps onto your underarms and allow to dry. Reapply during the day if required.






Scented Spritzer Deo

Many of us enjoy a little scent, and essential oils are a nice addition to a deo because many of them also have antibacterial properties of their own and therefore can help inhibit odour from bacteria.

Because essential oils need to be dissolved into a water base, we need a solubiliser here. I'm using Symbiosolv but you could also use  Resassol. I also added in some soothing allantoin.

I chose grapefruit and basil as my essential oils but feel free to use any others. Just keep in mind that the amount of solubiliser required may need to be adjusted accordingly.

0.25%  grapefruit essential oil or other essential oil of choice

Weigh out the essential oils and the Symbiosolv and mix them together in a beaker. Then add the water and stir until it dissolves the essential oil mixture. Add the zinc, allantoin and the preservative system, and mix thoroughly until everything is dissolved. Test and adjust the pH down to skin levels of around 4.5-5.5 with more citric acid if required.
