Be cautious with products containing bicarbonate of soda (also known as sodium bicarbonate or baking powder) or essential oils if you have sensitive skin or if you tend to shave your underarm hair, as it might cause irritation.

The Salt of the Earth Natural Deodorant Spray bottles are recyclable and made from 100% plant derived plastic. Additionally, the Unscented Natural Deodorant Spray by Salt of the Earth can also be refilled using the Salt of the Earth 500ml or 1ltr Unscented Natural Deodorant Spray Refill, reducing plastic waste even further.

VEGAN FRIENDLY - The entire Salt of the Earth range is 100% vegan and approved by both the Vegan Society and Vegetarian Society. Despite this declaration, many people still have doubts and concerns, which is why the entire Salt of the Earth range of deodorants is paraben free. For centuries, natural mineral salts have been used to prevent body odour. One of these natural salts, potassium alum, is the main active ingredient in Salt of the Earth’s Unscented Natural Deodorant Spray. Potassium alum creates an invisible antibacterial layer on the skin’s surface that helps to control the growth of bacteria, preventing body odour. The result is effective, long-lasting protection that allows your skin to breathe. There are sensitive formulas available. You might also wish to experiment with alternative hair-removal methods such as epilation or waxing, which might cause less irritation as they are longer lasting. Key ingredients include magnesium oxide and bicarbonate of soda (except in the Gentle range) to help prevent odours, as well as arrowroot for the sweat and shea butter to moisturise.

For example, crystal products such as Salt Of The Earth contain potassium alum, and PitRok is made from ammonium alum - both aluminium salts.

Extracts of essential oils provide the fragrances.

They come in a range of formats, including creams, pastes, crystals, roll-ons and pump-action spray formulas. If you like the active ingredient but prefer a different formulation, Salt of the Earth also has a spray, which also comes with the added benefit of being refillable. One user told us: 'The refills will last me about a year.'

It does this with a combination of natural plant and mineral powders to deodorise and absorb perspiration, including magnesium oxide and diatomaceous earth (a fossilised algae). It also contains sodium bicarbonate. It told us: 'Some people have questioned whether aluminium in some deodorants and antiperspirants can affect cancer risk. But the scientific evidence doesn't currently support a link, so we don't want people to worry.' It's worth remembering that natural ingredients can still cause skin reactions. For example, bicarbonate of soda can irritate the skin and cause itchiness, especially if used after shaving, and some essential oils that are commonly found in natural deodorants might also cause skin irritation. As for its eco credentials, Akt has a stylish recyclable aluminium tube and cap, and comes in cardboard boxes.Helps moisturise the skin: Formulated with natural moisturising factor, this deodorant helps moisturise your skin while keeping you fresh and odour-free. There's a range of unisex scents available, largely based on essential oils such as peppermint, citrus, rosemary and bergamot, as well as gender-specific options. One user told us the deodorant had done a 'decent' job but that it sometimes needed to be reapplied during the day. Dr Olioso says: 'I suspect this is more a case of people becoming more aware of and getting used to their own smell and how much they sweat - things they may have become dissociated from because of many years of using conventional products.'
