Thanks for the tip ArchtopK; its always good to know what other alternatives we have to the usual "baby powder" concentrated oils you can buy on eBay or Amazon, which are good by the way and are definitely better than nothing! By the way, I've started seeing some WalMarts carrying by single packages only, a new strawberry-pink package of scented wipes starting in 2018 named "Powder Fresh" that is pretty heavenly. Slightly different than your average "Baby Powder" scent, but different enough for some variety.
Back to the topic: Luvs has a similar but different scent than Pampers and I'd say would be just as valuable if there was some way to recreate either. I might even say I prefer the Luvs scent to Pampers as it had more of a plastic-scented flair to it that is hard to describe otherwise. Getting a hold of one or both of these scents, you could literally recreate an experience.
Slomo is definitely on to something and I have to say I agree. But, I think the smell that is being mimicked its closer to a concentrated urine scent. Concentrated urine smell can be scientifically designed to emphasize and synthesize the pheromones that might be normally found in healthy urine by either males, females or both. As many animals excrete pheromones in urine (humans included), the smell of urine is very much a factor in mating in much of the animal kingdom. Bear with me for a moment here: In my years of experience with urine smells, there are definitely bad urine smells (asparagus or the morning after a night drinking for example) and otherwise disgusting urine smells (when you are sick). If you eliminate the bad ones from our discussion and imagine the smell of a concentrated healthy urine where the ammonia has all evaporated away, there is a sweetness that is very close to the trio of baby scents we've all come to know and love: Pampers, Luvs and otherwise "Baby Powder". You might even guess the billion dollar diaper industry even in the 80s hired some scientists that didn't just design a random scent like roses to cover up a smell, but make a smell more palatable.
While I think the original idea was to make the smell more palatable for adults (thus using synthetic hormones), you didn't necessarily need something as strong as you would if you used something stand-alone, like a plain orange-scent, rose-scent, etc. Is it any wonder the two big competitors Luvs and Pampers made two different scents that were very close? Of course, in their experimentation with the population, these scents also activated something in the children's brains wearing the diapers making these scents more imprintable from a biological perspective. This isn't any different than what the expensive R&D budget has proven with the perfume industry over the past 100 years. At times, I've wondered if it was some conspiracy to get kids to wear diapers longer, thus boosting profits. Sounds kind of crazy now, but what corporation wouldn't have at least researched that idea in the 80s?
