Making your own DIY natural deodorant at home is simple, cost-effective, and a great way to reduce plastic packaging. It also allows you to customise ingredients and scents to suit your skin.
This homemade deodorant recipe that actually works uses just a few ingredients, requires no heating, and is free from aluminium, synthetic fragrances, parabens, and petrochemicals.
What ingredients make a DIY deodorant work?
This recipe combines antibacterial, absorbent, and skin-soothing ingredients:
- Bicarb (baking soda) – helps neutralise odour-causing bacteria
- Arrowroot or clay – absorbs moisture
- Coconut oil – antibacterial and moisturising
- Essential oils – optional scent and added antibacterial properties
Note: If you have sensitive skin, bicarb can cause irritation— use arrowroot only, try a bicarb-free deodorant, or see our guide to the best natural deodorant for sensitive skin.
What you need to make DIY deodorant
This recipe makes enough to fill approximately two small 120ml glass mason jars.
1/4 cup bi-carb soda or arrowroot powder
1/4 cup bentonite clay or kaolin clay
3.5 tbsp coconut oil
4 drops lavender essential oil
4 drops peppermint essential oil
4 drops rosemary essential oil
Optional: shea butter for a firmer texture- very moisturising and anti-bacterial, but this will require you to gently heat the mixture with a double-boiler method in order to melt and combine the ingredients.

It's recommended to test each ingredient on your wrist to ensure you aren't allergic to any of them.
How to make homemade deodorant (3 simple steps)
Step 1: Mix bi-carb and clay in a non-metal bowl using wooden utensils
Step 2: Mash in the soft coconut oil until well combined. This recipe will make a firm but smooth consistency, but you can add a little bit more coconut oil if you prefer a runny consistency.
Step 3: Stir in essential oils and transfer to a glass jar.
Store in a cool place.
How to use DIY deodorant
Apply a small amount to clean, dry underarms using your fingertips.
- Allow to absorb before dressing
- Wait after shaving before applying
- Reapply on hot or active days
If you are switching from conventional deodorant, your skin may go through a short adjustment phase. You can support this with a clay mask like Detox a Pit.
Common mistakes when making DIY deodorant
- Using too much bicarb (can irritate skin)
- Applying to damp skin

FAQs: DIY natural deodorant
Why is my homemade deodorant paste soft?
DIY deodorant can become soft or even melt depending on the temperature. Coconut oil naturally changes with heat — it’s solid in cooler conditions and turns liquid in warmer weather. If your deodorant feels too soft, try storing it in the fridge or adding a small amount of shea butter to help firm the texture. This can make it easier to apply, especially in warmer climates.
Does homemade deodorant actually work?
Yes — when formulated correctly, DIY deodorant can effectively reduce odour by targeting bacteria and absorbing moisture.
How long does homemade deodorant last?
Typically 2–3 months when stored in a cool, dry place.
Why does my DIY deodorant cause irritation?
This is usually due to bicarb. Switching to a bicarb-free recipe or reducing the amount can help.
Can I make a deodorant for sensitive skin?
Yes — use arrowroot instead of bicarb and avoid strong essential oils.
Is DIY deodorant better than store-bought?
It depends. DIY gives full ingredient control, while ready-made options are often more stable and convenient.
