INCI: Diisostearoyl Polyglyceryl-3 Dimer Dilinoleate
A gentle, plant-based emulsifier that creates a silky feel and helps stabilize formulas without clogging pores.
In plain English
This ingredient is a type of emulsifier, meaning it helps water and oil mix together in a product so it stays smooth and doesn't separate. It's made from plant-derived fatty acids and glycerin, and it gives creams and lotions a soft, silky texture without feeling greasy or heavy on the 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 Diisostearoyl Polyglyceryl-3 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
Diisostearoyl Polyglyceryl-3 Dimer Dilinoleate is a semi-synthetic emulsifier created by combining polyglycerin (from plant glycerin) with fatty acids (from plant oils) and dimer dilinoleic acid (from linoleic acid, a fatty acid found in many plant oils). It belongs to the polyglyceryl ester family, known for being mild and biodegradable.
How it works
In a cosmetic formula, this ingredient sits at the boundary between oil and water droplets, reducing surface tension so they blend into a stable emulsion. This prevents the product from separating into layers. It also forms a thin, non-occlusive film on the skin, which helps other ingredients spread evenly and leaves a smooth, velvety finish.
Pros
Gentle on skin
This emulsifier has a very low irritation and comedogenic rating, making it a safe choice for sensitive and acne-prone skin types.
Silky, non-greasy feel
It imparts a velvety, smooth after-feel that reduces the heavy or sticky sensation often associated with rich creams and sunscreens.
Cons and cautions
Not for ultra-light gels
If you prefer a watery gel texture, this ingredient may not be the best fit, as it works best in cream and lotion emulsions.
Higher cost
Because it's a specialty polyglyceryl ester, products containing it may be slightly more expensive than those using common emulsifiers.
Best for
- Anyone looking for a gentle, non-irritating moisturizer or sunscreen
- People with sensitive or reactive skin who want a lightweight, non-comedogenic formula
Use caution if
- Those seeking extremely lightweight gel textures may prefer a different emulsifier system
