Comes in pellet or flake form and must be heated and held to use. Much like Polawax, add the flakes to the heated oil phase and heat and hold that separately from the heated water phase. When both phases have reached 70˚C and have held for 20 minutes, remove from the double boiler and pour the oil or water phase into the other container. You can mix it with a hand mixer or stick blender.
For instance, at Lotioncrafter, emulsifying wax NF is listed as cetearyl alcohol and polysorbate 60, at Voyageur Soap & Candle as emulsifying wax NF without any specifics, and From Nature with Love as emulsifying wax (vegetable based) as Cetearyl Alcohol (and) Polysorbate 60 (and) PEG-150 Stearate (and) Steareth-20. Every supplier can be different, so keep notes as to what you've bought from whom and how it works in your product.
To substitute e-wax NF for Polawax, the general rule is to add 1% more to the emulsifier. So if Polawax has a usage rate of 25% of the oil phase, your rule for e-wax NF would be 25% of the oil phase, plus an extra 1%. If you have an oil phase of 20%, you'll be using 6% e-wax NF in the heated oil phase of your product. (20% x 0.25 = 5% + 1% = 6%). So how can we alter the recipe found in yesterday's post using Polawax to include e-wax NF?
BASIC LOTION RECIPE MODIFIED TO USE E-WAX NF
HEATED WATER PHASE (68.5% of the lotion)
HEATED OIL PHASE (29% of the lotion)
7% emulsifying wax
COOL DOWN PHASE (1.5% of the lotion)
1% fragrance or essential oil
0.5% preservative (I use liquid Germall Plus)
