This Fresh and Energising scent is just amazing for both men & women (my person Favourite ) stay dry all day long... What do you not put in the deodorant? No Aluminium, No aerosol gases/propellants, No Petroleum, Propylene Glycol or PEGs, No Artificial Fragrance, No Parabens or synthetic preservatives, No Tricolsan, No Phalates, No Alcohol, No GM modified ingredients. Why does Proverb not use aluminium? Aluminium is used to plug the sweat glands in your armpits and block them - it does this very successfully. However, the problem with this is, there has been many medical discussions about Aluminium having potentially harmful risks on your health - especially as it is being sprayed into a lymph node filled armpit. We don’t think it is worth the risk!
