The Swiss brand Biork offers ecological deodorants. The deodorant is a stick consisting of alum salt stone; this is hard and dry. When this comes into contact with water you can apply the deodorant. The deodorant dries quickly and is effective against sweat odours for up to twenty-four hours. An additional advantage is that the deodorant is dermatologically tested and does not cause skin irritations; therefore also very suitable for sensitive skin! The deodorant comes in a cork package that you can reuse. Cork is also a degradable material, so very environmentally friendly. Biork also feels a social responsibility in their production process: all products are free from child labor.
