Dipentaerythrityl Hexaisostearate
INCI: DIPENTAERYTHRITYL HEXAISOSTEARATE
A gentle, synthetic emollient that makes products feel silky and spread easily without clogging pores.
In plain English
Dipentaerythrityl Hexaisostearate is a man-made oil-like ingredient used in cosmetics to make the product feel smooth and silky on your skin. It helps other ingredients spread evenly and leaves a soft, non-greasy finish. Think of it as a lightweight, modern alternative to natural oils like coconut or jojoba, but designed to be less likely to clog pores.

Quick decision guide
Useful, but context matters
Dipentaerythrityl Hexaisostearate 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 Dipentaerythrityl Hexaisostearate.
- 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 created by combining dipentaerythritol (a type of alcohol) with isostearic acid (a fatty acid). It belongs to a family of ingredients called emollients, which soften and smooth the skin.
How it works
It sits on the surface of the skin, filling in tiny gaps between skin cells to create a smooth, even texture. It also reduces friction, so products glide on easily, and it helps other ingredients like pigments or active ingredients spread uniformly.
Pros
Silky, non-greasy feel
It leaves skin feeling smooth and soft without a heavy or sticky residue, making it ideal for daytime use or under makeup.
Low pore-clogging risk
Compared to many natural oils, this ingredient has a low comedogenic rating, so it's less likely to cause breakouts in acne-prone skin.
Cons and cautions
Synthetic origin
It is manufactured in a lab, which may be a turn-off for those seeking natural or plant-based ingredients.
Limited long-term data
While generally considered safe, there are fewer long-term studies on this specific ester compared to more traditional emollients.
Best for
- People with oily or combination skin looking for a lightweight moisturizer
- Anyone who wants a smooth, silky finish in makeup or skincare
Use caution if
- Those who strictly avoid synthetic ingredients in their routine
Usage tips
Safety summary
Dipentaerythrityl Hexaisostearate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types.
Research notes
Research on this specific ester is limited, but it is chemically similar to other well-studied emollient esters that are widely used and considered safe. The Cosmetic Ingredient Review has not flagged it as a concern.
Common label clues
- Typical concentration
- 1% to 10% in leave-on products
- Regulatory status
- Approved for use in cosmetics in the US, EU, and other major markets. The Cosmetic Ingredient Review (CIR) panel has evaluated similar esters and found them safe for topical use.
- Common uses
- Moisturizers, Lipsticks, Foundations, Sunscreens, Eye shadows
- Environmental note
- As a synthetic ingredient, its environmental impact depends on manufacturing practices. It is not biodegradable in the same way as natural oils.
Good to know
- It is often used in 'long-wear' makeup formulas because it helps pigments stay put.
- Despite its long name, it is chemically stable and does not easily oxidize or go rancid.
