Ethoxylated Fatty Acid Esters + PEG-100 Stearate
What is Ethoxylated Fatty Acid Esters + PEG-100 Stearate?
Ethoxylated Fatty Acid Esters and PEG-100 Stearate are synthetic compounds often used together as emulsifiers. They are created by chemically reacting fatty acids with ethylene oxide to produce a substance that blends oil and water effectively.
These compounds are used in a variety of personal care products to improve texture and consistency. While they help stabilize formulations, their impact on health is somewhat debated. Some concerns exist about potential skin irritation and the presence of impurities formed during production.
When you see these ingredients on a label, it's important to consider their origin and manufacturing processes, as this can influence their purity and safety.
Commonly found in: feminine care products, lotions, creams, hair conditioners
What to watch
- May cause skin irritation in sensitive individuals.
- Potential contamination with 1,4-dioxane, a byproduct of the ethoxylation process.
Benefits
- Enhances the stability and consistency of emulsions in personal care products.
The FDA allows the use of these compounds but regulates them to ensure safety limits for impurities.
Some studies suggest potential irritant effects, but overall safety is supported by current research when used within recommended concentrations.
These ingredients are typically synthetic and not derived from animal sources, making them generally acceptable for vegans.

Scout's take
Two ethoxylated ingredients that carry contamination risk from 1,4-dioxane, a probable human carcinogen and byproduct of the ethoxylation manufacturing process. Present in a product with prolonged vaginal mucosal contact where absorption rates are significantly higher than skin.
