Butylethylpropanediol Dimer Dilinoleate
INCI: BUTYLETHYLPROPANEDIOL DIMER DILINOLEATE
A lightweight, non-greasy emollient that softens skin and improves product texture with low irritation potential.
In plain English
Butylethylpropanediol Dimer Dilinoleate is a synthetic oil-like ingredient that helps moisturize and soften the skin. It spreads easily, feels lightweight, and doesn't leave a heavy or sticky residue. It's often used to improve the feel of creams, lotions, and sunscreens, making them smoother and more pleasant to apply.

Quick decision guide
Useful, but context matters
Butylethylpropanediol Dimer Dilinoleate 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 Butylethylpropanediol Dimer Dilinoleate.
- 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 ester made from butylethylpropanediol (a type of diol) and dimer dilinoleate (a fatty acid derived from linoleic acid). It is designed to mimic natural skin oils and provide emollient benefits.
How it works
It forms a thin, breathable film on the skin's surface that helps reduce water loss (transepidermal water loss, or TEWL — the amount of moisture that evaporates from your skin). This film also fills in tiny gaps between skin cells, making the skin feel smoother and softer. In formulations, it helps other ingredients spread evenly and improves the overall texture.
Pros
Lightweight feel
Unlike heavier oils, this ingredient absorbs quickly without leaving a greasy residue, making it ideal for daytime use or under makeup.
Texture enhancer
It improves the slip and spreadability of products, so creams and sunscreens feel smoother and more luxurious on the skin.
Cons and cautions
Synthetic origin
Some consumers prefer naturally derived emollients, and this ingredient is fully synthetic, which may be a consideration for 'clean beauty' preferences.
Limited research
While generally considered safe, there are fewer peer-reviewed studies on this specific ester compared to more common emollients like squalane or glycerin.
Best for
- People with normal to dry skin looking for lightweight hydration
- Those who prefer non-greasy, fast-absorbing moisturizers
Use caution if
- Individuals with known sensitivity to synthetic esters (rare)
Usage tips
Safety summary
Butylethylpropanediol Dimer Dilinoleate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types. As with any ingredient, patch test if you have sensitive skin.
Research notes
Safety assessments by cosmetic ingredient review panels and regulatory bodies support its use as a skin-conditioning agent. Specific studies on this ester are limited, but it is structurally similar to other safe dimer esters used in cosmetics.
