A smelly business
There are two main types of deodorant: simple deodorants that eliminate odour, and antiperspirants which contain ingredients (most commonly aluminium or aluminum chlorohydrate) that block pores to reduce sweating.
Some research suggests that aluminum-based compounds may be absorbed by the skin and cause oestrogen-like (hormonal) effects like breast cancer. Other studies suggest that blocked pores result in the spread of cancer-causing toxins.
The following brands are aluminium free: Green People, Faith in Nature, Little Satsuma, Weleda, Neal’s Yard, Salt of the Earth, Urtekram, Lavera, Lush, Pitrok, Dr Hauschka.
A natural method of deodorising is to use deodorant crystal stones which are made from potassium or ammonium alum, a natural mineral salt that inhibits the growth of the bacteria responsible for body odour. They come as either a solid stone on its own or in a push-up stick, or in liquid form.
Of our Best Buys, Faith in Nature, Little Satsuma, Salt of the Earth and Urtekram make push-up stick varieties of crystal deodorant stones.
