    It's probably confusing. By sugar alcohol I mean polyalcohols such a glycerin, but also propandiol, butandiol and so on. I believe it's understandable that blends of alcohols, polyalcohols and PEGs have better dissolving properties compared to each of them alone.
    Thanks for pointing it out, and letting me explain it better.
