Emulisifying Wax - NF.
Emulsifying wax is a cosmetic emulsifying ingredient. The ingredient name is often followed by the initials NF, indicating that it conforms to the specifications of the National Formulary.
Emulsifying wax is created when a wax material (either a vegetable wax of some kind or a petroleum-based wax) is treated with a detergent (typically sodium dodecyl sulfate or polysorbates) to cause it to make oil and water bind together into a smooth emulsion. It is a white waxy solid with a low fatty alcohol odor.
The ingredients for Emulsifying Wax NF are: Cetearyl Alcohol, Polysorbate 60, PEG-150 Stearate, and Steareth-20. It has the characteristics of cetyl alcohol combined with the viscosity building effect of stearyl alcohol as an effective thickener and helps form stable emulsions.
