Try Nivea normal or sensitive (perfume free) if you can get it. Never had a better one. No strong perfume of its own and never turns sour as some do. Hope this helps. Not sure if it`s easily available in UK.
A natural, ozone-safe deoderant spray is made by Weleda, using various herbs. It is ONLY a deoderant, not an anti-perspirant. Available from independent chemists (I don`t think that Boots or the supermarkets do it) and health food shops.
I had a bad reaction to a deoderant spray many years ago, I tried a few roll-on deoderants until I found the one which suited me best which is Amplex sensitive. X X X :-)
