    I’ve never had a problem and I use it as reinforcement for the preservative system.  I suppose it depends on your emulsification system. 
    Quite frankly this article (link) was useless to me. The minimal information given says nothing about the emulsifer except that it was a ‘non ionic surfactant’. Hell, that could be glyceryl stearate or it could be CAPB for all we know. And, emulsifying paraffin?? That is not representative of anything I am interested in.

    I can’t see how much they used. My anecdotal evidence suggests it’s the other way around. Glycols are much less problematic than some other humectants.

    Post ingredients and percentages, without a good emulsifier that would happen
