Ingredient review
Ethylene Dodecanedioate
INCI: Ethylene Dodecanedioate
Ethylene Dodecanedioate is a synthetic ester that adds a pleasant musky scent to products and helps condition the skin, but it offers no active skincare benefits.
In plain English
Ethylene Dodecanedioate is a man-made ingredient that smells like musk and is added to cosmetics to give them a nice fragrance. It also helps make the skin feel a bit softer by forming a light film on the surface. It doesn't treat any skin concerns or provide long-term benefits—it's mainly there for scent and texture.

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 Dodecanedioate.
- 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
Ethylene Dodecanedioate is a synthetic ester created by reacting ethylene glycol with dodecanedioic acid. It belongs to a class of compounds known as macrocyclic musks, which are prized in perfumery for their warm, long-lasting scent.
How it works
In a cosmetic product, Ethylene Dodecanedioate acts as a fragrance ingredient by releasing a musky aroma that can mask other odors or add a pleasant scent. It also functions as a skin conditioning agent by depositing a thin, non-greasy film on the skin, which can temporarily improve feel and reduce water loss.
Pros
Pleasant scent
Adds a warm, musky fragrance that is long-lasting and can enhance the user experience of a product.
Skin feel improvement
Helps create a smooth, soft feel on the skin without being greasy, making the product more enjoyable to apply.
Cons and cautions
No active benefits
Does not provide any proven skincare benefits like hydration, anti-aging, or protection—it's purely for fragrance and texture.
Potential irritant for sensitive skin
As a fragrance ingredient, it can cause allergic reactions or irritation in people with sensitive skin or fragrance sensitivities.
Best for
- People who enjoy scented skincare products
- Those looking for a subtle, warm fragrance in their routine
Use caution if
- Individuals with known fragrance allergies or sensitive skin that reacts to scented products
Usage tips
Safety summary
Ethylene Dodecanedioate is generally recognized as safe for use in cosmetics at typical concentrations. It has low irritation and sensitization potential, but like all fragrance ingredients, it can cause reactions in sensitive individuals.
Research notes
Research on Ethylene Dodecanedioate focuses on its fragrance properties and safety profile. Studies indicate low acute toxicity and skin irritation, but long-term exposure data in humans is limited. It is not associated with significant health risks when used as directed.
Common label clues
- Typical concentration
- Typically used at very low concentrations (under 1%) due to its strong scent profile.
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. The International Fragrance Association (IFRA) sets usage limits to ensure safety.
- Common uses
- Fragrances, Perfumes, Body lotions, Cleansers
- Environmental note
- As a synthetic compound, it is not biodegradable in all environments. Some synthetic musks have raised concerns about bioaccumulation, though Ethylene Dodecanedioate is considered less persistent than older musk types.
Good to know
- Ethylene Dodecanedioate is also known as Ethylene Brassylate and is commonly used in fine fragrances.
- It is considered a 'macrocyclic musk,' which is a type of synthetic musk that mimics natural musk scents without animal-derived ingredients.
