Ingredient review
Ditridecyl Adipate
INCI: Ditridecyl Adipate
A lightweight, non-greasy emollient that helps skin feel soft and smooth without clogging pores.
In plain English
Ditridecyl Adipate is a synthetic oil-like ingredient made from adipic acid and a type of alcohol. It spreads easily on the skin, leaving a silky, non-sticky feel. Because it's lightweight, it's often used in products that need to absorb quickly, like sunscreens and lightweight moisturizers. It also helps other ingredients dissolve and spread evenly.

Quick decision guide
Useful, but context matters
Ditridecyl 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 Ditridecyl 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
A diester formed from adipic acid and tridecyl alcohol, created through a controlled chemical process. It belongs to the adipate family of emollients, known for their light, non-greasy texture.
How it works
Sits on the surface of the skin to fill in tiny gaps between skin cells, making the skin feel smoother and softer. It also reduces water loss from the skin by forming a thin, breathable barrier. In formulations, it helps dissolve other oil-soluble ingredients and improves the spreadability of the product.
Pros
Lightweight feel
Unlike heavier oils, ditridecyl adipate absorbs quickly and leaves a silky finish, making it ideal for daytime moisturizers and sunscreens.
Low pore-clogging risk
Rated low on the comedogenic scale, so it's unlikely to cause breakouts for most skin types, including acne-prone skin.
Cons and cautions
Synthetic origin
It is manufactured in a lab, which may be a drawback for consumers seeking 100% natural or plant-derived ingredients.
Potential heaviness on oily skin
While generally lightweight, very high concentrations in a formula could feel slightly heavy on extremely oily skin compared to silicone-based alternatives.
Best for
- People with normal to dry skin looking for lightweight moisture
- Anyone who wants a non-greasy sunscreen or makeup base
Use caution if
- Those who strictly avoid synthetic ingredients
- Individuals with very oily skin may prefer even lighter alternatives like dimethicone
Usage tips
Safety summary
Ditridecyl adipate is considered safe for use in cosmetics at typical concentrations. It has low irritation and sensitization potential, and is not known to be toxic or carcinogenic. Regulatory panels like the Cosmetic Ingredient Review (CIR) have reviewed similar adipates and found them safe.
Research notes
While not extensively studied in isolation, the adipate ester family is well-documented for safe use in topical products. Studies show low skin irritation and no significant systemic absorption. Most safety data comes from industry submissions and regulatory reviews.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics in the US (FDA), EU (CosIng), and many other regions. No concentration restrictions are typically imposed.
- Common uses
- Moisturizers, Sunscreens, Makeup, Lip products, Hair conditioners
- Environmental note
- As a synthetic ester, it is not biodegradable in the same way as natural oils, but it is not classified as a persistent environmental pollutant.
Good to know
- Ditridecyl adipate is often used in sunscreens because it helps dissolve chemical UV filters and improves the even application of the product.
- It is considered safe for use in cosmetics by major regulatory bodies.
