No scent at all.
The product has not changed. the instructions and packaging is totally new ("and improved"). My daughter is asthmatic (and allergic to a ton of things) and the pouch has no effect on her. The contents are non-irritating and very little excess gets in the air (unless you tap it heavily) and both styles are lined so it doesn't get on your hands. The little one sometimes leaves a very, very tiny residue when you set it down (I leave mine in a soap dish at all times) but often doesn't and if you turn the Strap n Tap upside down on your work surface or in your soap dish, there is no residue at all ever because of the lining.
PS One pouch will probably last you a lifetime --if you don't lose it.
