Ingredient review
Pentaerythrityl Cyclohexane Dicarboxylate
INCI: Pentaerythrityl Cyclohexane Dicarboxylate
A lightweight, non-greasy emollient that helps products glide on smoothly without clogging pores.
In plain English
This is a synthetic oil-like ingredient that makes skincare and makeup feel silky and spread easily on your skin. Unlike heavy oils, it doesn't leave a sticky or greasy residue, so it's often used in lightweight moisturizers and sunscreens. It's also considered very unlikely to clog pores, making it a good choice for acne-prone skin.

Quick decision guide
Useful, but context matters

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 Pentaerythrityl Cyclohexane Dicarboxylate.
- 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
Pentaerythrityl Cyclohexane Dicarboxylate is a diester made from pentaerythritol and cyclohexane dicarboxylic acid. It is a clear, colorless liquid that acts as an emollient and skin conditioner in cosmetic formulations.
How it works
It sits on the surface of the skin, filling in tiny gaps between skin cells to create a smooth, soft feel. It also helps other ingredients spread more evenly and can improve the texture of a product without adding heavy oiliness.
Pros
Lightweight feel
Unlike many oils, this ingredient leaves a silky, non-greasy finish that won't weigh down your skin or make it look shiny.
Pore-friendly
It has a very low comedogenic rating, meaning it's unlikely to clog pores, which is great for acne-prone or sensitive skin types.
Cons and cautions
Synthetic origin
It is manufactured in a lab, so it won't appeal to those who prefer plant-based or naturally derived ingredients.
Limited long-term data
While generally considered safe, there is less published research on this specific ester compared to more common emollients like jojoba oil or squalane.
Best for
- People with oily or acne-prone skin looking for a lightweight moisturizer
- Anyone who dislikes heavy, greasy skincare textures
Use caution if
- Those who strictly avoid synthetic ingredients in their routine
