Ask the GH

 

I received an excellent sunscreen question from GH reader, Na.  As you have been reading the past month on Goddess Huntress and the Environmental Working Group’s 2011 Sunscreen Report, that we should opt for non-nano zinc oxide or non-nano titanium dioxide as the active ingredient in our sunscreens.  Well, Na is finding out that manufacturers are getting clever in avoiding listing the word “nano” on their labels.

Q: Is Micronized Zinc Oxide or Titanium Dioxide considered okay?

A: Excellent question, Na. “Micronized” is a broad and ambiguous term used by manufacturers. Micronized means that the zinc oxide/titanium dioxide particles have been reduced in size.  This size can be nanoparticle size or larger than nanoparticle size to be “micronized”.  If your sunscreen goes on clear or the whiteness disappears quickly, then it is nanoparticle size and I’d advise to stay away.  If it rubs on white then it is not nano, and that is a great.

Now if only our labels can deliver these important details!

Got a question?  Send me an email, yo!

    Have you ever taken a look at CōTZ Suncare lne? The inventor was the original Dr. who introduced Zinc to surfers in the 70’s. Great product range, worth looking at!
