Here's a recent "ask the expert" question submitted on Zaega.com.
Q: I notice that you have products on your site that use emulsifying wax NF. What is that truth on this ingredient? Does it contain petrochemicals?
A: (from Melissa, the expert cosmetic chemist) Emulsifying wax is a commonly used emulsifying ingredient in lotions, creams and conditioners. There are a few different types of emulsifying wax, but the most common is a blend of fatty alcohols (nontoxic, nonirritating emollient-type surfactants –see my article on alcohols here) and polysorbate-60 (a synthetic ethoxylated ingredient which is a very good emulsifier). There is also an organic emulsifying wax which is a blend of beeswax, carnauba wax and lecithin. Generally-speaking these ingredients are used in emulsions at less than 5% and are nontoxic, nonirritating and mostly naturally-derived.
