just made some spearmint soap. i used the titanium dioxide to whiten up a bit and while i'm happy w/ the color of the white......there are some small specks of TD visible in the soap. the smell is wonderful as i used some spearmint eo....just a little as i had heard it can be irritating to sensitive areas :wink: i will just use these at home as the little white specks make these less than perfect, but there really aren't too many of them, it could have been a hole lot worse. does spearmint eo discolor to brown at all? or do the leaves? there are some areas that look a bit brownish instead of green on top of the soaps, where i sprinkled the spearmint.
