  1. Step 1Start with the score, then check the irritation and clogging risk before judging Ethylene Dodecanedioate.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

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

Patch test any product containing this ingredient if you have sensitive skin or a history of fragrance allergies.
Use scented products containing this ingredient in the evening if you prefer a fragrance-free daytime routine.

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.
