mcleodnaturals,
I second your question and add this...
I have been reading and reading about SPF for lip balms and wow nothing is "really" safe lol.
Ok, I have narrowed it down to titanium dioxide and/or red raspberry oil.
I did find this chart (see link)
http://www.pvsoap.com/SPF_chart.htm
It shows how much to add, but I have read that micronized or nano can be bad for us as the particles become so small they can pass through the skin and into cells. They say that the regular sized bigger than 15... **** I forget the measurement they used... is safer, but less effective. Both zinc and titanium dioxide are also better because they refract the bad uvs instead of the chemicals that absorb.
I really like the idea of red raspberry oil, but have yet to find an spf chart to know how much to use, it is pricey! Said to be between 28 and 50 spf, but at what amount and so on...
This is an interesting site too (see link)

I hope someone else has more knowledge that they will share
:wink: :wink:
Oh yes! I do want spf in my lip balm, but do understand that I can not label it claiming spf, as that would change it to an over the counter drug and turn the eye of the FDA on me
Thanks,
Jeff
