No plastic packaging. No synthetic fragrance. No faff. Our Plastic Free Crystal Deodorant is made from just one ingredient: potassium alum, a natural mineral salt that’s been used for centuries as a deodorant. You simply wet the crystal and apply it to clean underarms — creating an invisible layer of protection that helps reduce odour-causing bacteria. 

No aerosols, no overpowering scent, no drama. Just reliable, fragrance-free freshness that fits into even the most minimalist of routines.

🌍 Why It’s a Great Swap for Plastic Free July

Not all deodorants are created equal — and we don’t mean in terms of fragrance options or fancy packaging. If you're looking to reduce single-use plastic this month (or anytime), here’s why our Plastic Free Crystal is a go-to:

• Plastic-Free Packaging: Housed in recyclable cardboard — no plastic cap, twisty bits, or dispensers here.
• Refill-Free Simplicity: It doesn’t need refilling. It just lasts. Some customers say theirs has lasted over a year with daily use.
• Fragrance-Free Flexibility: Unscented means it won’t compete with your perfume, essential oils, or body spray — and it’s ideal if you prefer to keep things neutral.

🙌 Low-Waste Living, The Easy Way 

If Plastic Free July feels a bit overwhelming, start with one product. This one. It’s the kind of swap that asks very little of you but gives back plenty — less plastic in your routine, one less bottle in the bin, and more room for simple, sustainable habits. Deodorant doesn’t need to shout to be effective. The Salt of the Earth Plastic Free Crystal does its job quietly and consistently — and we love it for that.

💡How to Use It:

1. Wet the crystal under the tap (or apply straight after a shower).
2. Rub it gently on clean underarms.
3. Let it dry, pop it back in the box, and go.
