Dimethyl Adipate
INCI: Dimethyl Adipate
A lightweight, non-greasy emollient that helps other ingredients spread smoothly and evaporates quickly, leaving a silky feel.
In plain English
Dimethyl Adipate is a synthetic oil-like ingredient that makes creams and lotions feel light and silky instead of heavy or sticky. It also helps dissolve other ingredients and evaporates quickly from the skin, so it doesn't leave a greasy residue. Think of it as a helper that improves the texture and feel of your products.

Dimethyl Adipate 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 Dimethyl Adipate.
- 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
Dimethyl Adipate is a diester derived from adipic acid and methanol. It is a clear, colorless liquid with a faint, pleasant odor, used primarily as an emollient and solvent in cosmetics.
How it works
It sits on the skin's surface to soften and smooth it (emollient action), while also helping to dissolve and blend other ingredients like oils, fragrances, or active compounds. Its low viscosity and quick evaporation give a lightweight, non-tacky finish.
Pros
Lightweight feel
It evaporates quickly and leaves a silky, non-greasy finish, making it ideal for oily or combination skin types.
Improves product texture
It helps creams and serums spread more evenly and absorb faster, enhancing the user experience.
Cons and cautions
Synthetic origin
It is not a natural ingredient, which may be a drawback for consumers seeking plant-based or naturally derived products.
Limited research
While generally considered safe, there is less published research on its long-term skin effects compared to more common emollients like glycerin or squalane.
Best for
- People with oily or combination skin who prefer lightweight textures
- Anyone looking for a non-greasy moisturizer or makeup remover
Use caution if
- Those with known sensitivity to synthetic esters or adipic acid derivatives (rare)
Usage tips
Safety summary
Dimethyl Adipate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types. Rare allergic reactions are possible, as with any ingredient.
Research notes
The Cosmetic Ingredient Review (CIR) panel has evaluated Dimethyl Adipate and concluded it is safe as used in cosmetics. Studies show low acute toxicity and minimal skin irritation. However, long-term human skin studies are limited.
Common label clues
- Typical concentration
- Typically 1–10% in leave-on products; higher in rinse-off products
- Regulatory status
- Approved for use in cosmetics by the FDA and EU CosIng database. The Cosmetic Ingredient Review (CIR) panel has reviewed it and found it safe at typical use concentrations.
- Common uses
- Moisturizers, Cleansers, Makeup removers, Fragrance formulations
- Environmental note
- Dimethyl Adipate is biodegradable, but as a synthetic compound, its production relies on petrochemical feedstocks.
Good to know
- Dimethyl Adipate is often used in combination with other esters to create a 'dry' oil feel.
- It is also used in some industrial applications, but cosmetic-grade material is purified for safety.
