Wait wait wait! You're combining two conversations here.
The whole "gentle and safe" conversation had to do with Paula's take on SLS - that side convo has nothing to do with the humectants.
There are some people who think that SLS can cause cancer, etc... she argues that SLS is gentle and safe - SAFE I get, but gentle?!
Humectants ARE "safe"- both CG and shouldn't cause tumors.
Humectants are totally CG, but just not especially advisable in low dew points. The question at hand though - is aloe vera a humectant? That's why I'm trying to determine if aloe vera needs to be relegated to the "summer only" box or not.
