Emulsifying wax is not a natural ingredient. The standard formulation, known as Emulsifying Wax NF, is a blend of cetearyl alcohol and polysorbate 60. While one of those components can come from plants, the other is synthesized through an industrial chemical process, which disqualifies the finished product from being considered natural under most regulatory definitions.
What Emulsifying Wax Is Made Of
Emulsifying wax NF contains two main ingredients. Cetearyl alcohol is a fatty alcohol that, despite the name, is a waxy solid rather than a drying liquid alcohol. Over 90% of the global fatty alcohol supply now comes from vegetable sources, primarily palm and coconut oil, rather than petroleum. On its own, cetearyl alcohol has a reasonable claim to being a plant-derived ingredient.
The second ingredient, polysorbate 60, is the reason emulsifying wax falls outside the “natural” category. Polysorbate 60 is manufactured by reacting sorbitan fatty acid esters with roughly 20 units of ethylene oxide, a process called ethoxylation. This is an industrial chemical reaction, and it transforms the starting materials into something that no longer exists in nature. Even though the fatty acids in polysorbate 60 can originate from plants, the ethoxylation step is what makes the final ingredient synthetic.
Why “Naturally Derived” Isn’t the Same as “Natural”
This distinction trips up a lot of people, and the cosmetics industry doesn’t always make it easy. Under proposed U.S. legislation (the Natural Cosmetics Act), a “natural” ingredient must be either unprocessed or processed only through simple physical means like heating, dissolving in water, or mechanical extraction. A “naturally derived” ingredient, by contrast, starts from a plant, mineral, or animal source but has been chemically processed along the way.
Emulsifying wax NF fits squarely in the “naturally derived” camp. Its raw materials trace back to plant oils, but the chemical transformation involved in creating polysorbate 60 means it can’t be labeled natural. For a product to carry a “natural” label under the proposed standard, at least 70% of its substances (excluding water and salt) must qualify as truly natural.
Certification Standards and Emulsifying Wax
Major organic and natural certification bodies like COSMOS and ECOCERT evaluate ingredients on a case-by-case basis. Approval is granted to specific raw materials from specific manufacturers, not to generic ingredient categories. Emulsifying Wax NF as a generic formulation is not universally approved under these standards, largely because ethoxylated ingredients like polysorbate 60 are restricted or prohibited. Some emulsifying wax suppliers do hold RSPO (Roundtable on Sustainable Palm Oil) certification for sustainable sourcing, but sustainable sourcing and “natural” are two different questions.
A Trace Contaminant Worth Knowing About
The ethoxylation process that creates polysorbate 60 can leave behind trace amounts of 1,4-dioxane, a manufacturing byproduct. The FDA has noted that this compound shows up in extremely small quantities in some cosmetics containing ethoxylated ingredients, identifiable by prefixes like “PEG,” “polyethylene,” or “polyoxyethylene.” Europe’s Scientific Committee on Consumer Safety has concluded that levels at or below 10 parts per million are safe. Since the 1980s, the FDA has recommended that manufacturers use a vacuum stripping technique to reduce 1,4-dioxane levels. This isn’t a reason to panic about emulsifying wax, but it is one more reason the ingredient sits firmly on the synthetic side of the line.
Plant-Based Alternatives That Qualify as Natural
If you’re formulating skincare products and want a genuinely natural emulsifier, several options exist. They tend to cost more and sometimes behave differently in formulations, but they can produce stable, effective creams and lotions.
- Olivem 1000 (derived from olive oil): Used at 3 to 5 percent, it forms liquid crystal structures that mimic the skin’s own barrier. It works well for sensitive, dry, or barrier-compromised skin and leaves a soft, non-greasy finish.
- Simulgreen 18-2 (vegetable origin): A lightweight emulsifier used at 2 to 3 percent, best suited for gel creams and formulations for oily or acne-prone skin. It absorbs quickly without a heavy feel.
- Emulsan II (plant-based sugar and fatty acid ester): Used at 2 to 5 percent, compatible with a wide range of active ingredients. It delivers a smooth texture and works reliably for normal to dry skin types.
- Montanov 68: Recommended for dry or mature skin due to its deep moisturizing properties and structural stability.
Traditional beeswax-borax systems also count as natural emulsifiers, though they’re trickier to work with. The emulsion type you get (oil-in-water versus water-in-oil) depends on the ratio of water to oil. If the water phase is below 45%, you’ll end up with a water-in-oil emulsion. At 45% or above, it flips to oil-in-water. This sensitivity to ratios makes beeswax-borax formulations less forgiving than modern emulsifying wax, which is one reason Emulsifying Wax NF became so popular in the first place.
Why People Still Use It
Emulsifying wax NF remains a staple in DIY skincare and professional formulation because it’s reliable, inexpensive, and easy to use. It produces stable emulsions across a wide range of oil-to-water ratios without the fussiness of natural alternatives. For many formulators, “naturally derived” is good enough, and the performance trade-offs of switching to a fully natural emulsifier aren’t worth it. But if your goal is a product that meets strict natural or organic certification standards, emulsifying wax NF won’t get you there. You’ll need to look at the plant-based alternatives and accept the learning curve that comes with them.
