I know this is a bit extreme but i got a bunch of soapstone (talc) I am a welder so i just grab a bunch and grind it down. No smell what so ever and baby powder is usualy made up of corn starch or talcum powder aka talc aka soapstone HOORAY FOR WIKIPEDIA!!!!
I use cornstarch base powder with aloe...smells like baby powder is supposed to smell! I saw the others...but to me lavender smells like old ladies, NOT babies...and I think a cucumber-melon smell would be a bit too, I dunno, 'new age'!
