The travel size crystal deodorant stone is great for taking on holiday. Its small size means that the normal fight for space in your wash bag will be a thing of the past. Like our Crystal Classic, it's made purely from natural mineral salts and is effective at keeping body-odour at bay. It can last for months, so it’s a great choice for extended holidays. Long Lasting Protection 100% Natural No White Marks Unisex Vegetarian and Vegan Society Approved Not Tested on Animals How does crystal deodorant work? Applied to damp skin after washing, the Classic Natural Crystal Deodorant leaves a thin layer of natural mineral salts on your skin. These mineral salts are a natural deodorant and inhibit the formation of body odour on your skin, providing you with long lasting protection. The Salt of the Earth Travel crystal deodorant is a 50g stick of pure Potassium Alum, a natural mineral salt that has been used as a deodorant for hundreds of years. Our crystal deodorants are unscented so they won’t interfere with other fragrances like perfume or body lotion.
