Thanks for the info, worth knowing for future. I've been using the Dermalogica Environmental Control Deodorant after the Clinique Deodorant Stick ruined my shirts due to staining.
Have to say the Dermalogica product is fantastic, smells great from natural ingredients, goes on invisible and doesn't leave any residue at all. Recommended if you fancy a change in the future. I find after a few uses your body adapts to an anti-perspirant and you need to change.
