This remains a quest for me - finding this scent. I have on occasion found that smell wafting in a parking lot twice in my life. And that tells me that there are perfumes out there that have a base note that resembles Vintage Pampers.
It would really be nice to be able to talk to some of the P&G pioneers to learn specifically why a scent was chosen, and what the goal of that scent was. I once communicated with P&G and they did admit that the original scent was far removed from the common baby powder scent. and that when they reintroduced the scent in the late 90's baby powder became the goal. I always felt that the scent was very feminine, big and beautiful. I recently tried to ask P&G if they had a historian that could comment on the scent and just got a canned response. Their last historian runs a cookie shop in Ohio now, but I doubt I will hear back from her. This really should not be as difficult as it has proven to be. Vic Miles recently retired and RC Duncan still works there. These are the names on the early patents.
