Dude deodorant: because it’s just so hard to find non toxic deodorants for teens. I’ve used this myself, and I like it. And it smells good, too. My sons use this. The base ingredients include tapioca starch for moisture absorption and sodium bicarbonate for odour control. It also contains a range of natural fragrances including patchouli oil. There are several scents to choose from. This fragrance-free vegan deodorant (or 'anti-odorant' as it calls itself) comes in the form of a tube of cream that you apply to the underarms by hand.

You won't currently find most of these products in high street stores (aside from Holland and Barrett, which has a good range), so it can take a bit of time and research to figure out what's out there and what's best for you. Many of these chemicals are thought to be harmful to your health and may irritate sensitive skin. It’s important that you read the ingredient list for all deodorants, even if they’re labeled “natural.”In recent years, it has gained popularity in the U.S. because of its natural ingredients and potential health benefits. But it won’t have the exact same effects as your standard deodorant product. Crystal deodorant is made from a mineral salt called potassium alum, a zeolite mineral salt. Potassium alum has been used for centuries in Southeast Asia as a natural deodorant because of its antibacterial, anti-odor properties.

It’s very budget-friendly, paraben-free, aluminium-free fragrance-free, definitely not tested on animals and will provide the long-lasting protection you’re looking for, even under extreme conditions. What more could you ask for in a deodorant?According to Green People, potassium alum is a much larger molecule, so it can’t be absorbed by the skin.

Unlike mainstream antiperspirants or deodorants, it doesn’t prevent your body from naturally sweating, but instead uses alum to reduce bacteria growth, minimise odours and take care of your body. The aluminum sulfate is commonly produced by treating minerals bauxite ore (the main component aluminium oxide) with sulfuric acid. Here is the chemical reaction equation: Al2O3 + 3H2SO4 =Al2(SO4 )3 + 3H2O These bacteria that thrive in sweaty, dark areas of the body produce smelly acids and sulfur compounds that cause body odor. Salt deodorant works to fight and prevent bacteria growth, reducing the chances of body odor forming. It’s ultra-gentle, highly effective and contains natural prebiotics to help keep the skin’s natural flora in perfect balance.

Ingredient concerns

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.'
