Ethylene Dilinoleamide is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Ethylene Dilinoleamide.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A synthetic amide derived from linoleic acid (a fatty acid) and ethylene diamine. It is a waxy solid at room temperature and is used primarily as a thickening agent and emulsion stabilizer.
How it works
It works by forming a network of tiny crystals in the oil phase of a product. This network traps water droplets, creating a stable emulsion (like a cream or lotion) and increasing the product's viscosity, making it thicker and more luxurious in texture.
Pros
Improves product texture
Gives creams and lotions a smooth, rich feel that spreads easily without being greasy.
Low irritation potential
Generally well-tolerated by most skin types, including sensitive skin, with a low risk of causing breakouts or irritation.
Cons and cautions
Synthetic ingredient
Not naturally derived, which may be a drawback for those seeking plant-based or 'clean' beauty products.
No active skin benefits
Its role is purely textural and stabilizing; it does not moisturize, soothe, or treat the skin directly.
Best for
- Anyone who enjoys rich, creamy moisturizers and lotions
- People looking for stable, well-formulated products
Use caution if
- Those who prefer 100% natural or plant-derived thickeners
