My DH and DD use the same deodorant as I do. I haven't heard them complain, and haven.'t seen white on their clothes or yellow on their whites. My DH has both light (including white) dark (wine burgundy, red, Royal blue and black), and I do the laundry. I think if it caused any type of discoloration, he would complain. He actually prefers this deodorant & asks me to buy it for him.

I use Crystal which I guess is some type of rock so has zero scent. It doesn't help wetness since it is a deodorant and not an antiperspirant. I run so cold these days that I don't need an antiperspirant as I did when I was younger.

After years of buying the strongest deodorant I could find, I moved to a natural deodorant a year or so ago for health reasons. Soapwalla was my pick and (skeptical as I was) it is the BEST deodorant I have ever used. It comes as a cream, a mix of Shea butter and kaolin and essential oils. You scoop out a pea size piece and rub it in your armpit. I thought this was a bit ick at first, but then I realised it was all good ingredients and rubbed any leftover on my hands (lots of people use it as for hair styling). And then, it just works, effortlessly. I never get white marks (yay) and I never get that metallic smell at the end of a day from the aluminum. I love it and would never go back to conventional deodorant.
