Ingredient review
Polybutylene Glycol Dipalmitate
INCI: POLY(1,4-BUTANEDIOL)-9 DIPALMITATE
A gentle synthetic emollient that helps soften and smooth skin without clogging pores.
In plain English
This ingredient is a man-made oil-like substance that spreads easily on the skin, making it feel soft and smooth. It's similar to natural oils but designed to be lightweight and non-greasy. Because it's large in molecular size, it sits on the skin's surface rather than penetrating deeply, which helps reduce the chance of irritation or breakouts.

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 Polybutylene Glycol Dipalmitate.
- 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 formed from polybutylene glycol (a polymer) and palmitic acid (a fatty acid). It functions as an emollient and skin conditioner.
How it works
It forms a thin, breathable film on the skin that reduces water loss and fills in rough patches, leaving the skin feeling smooth and hydrated. Its large molecular structure means it stays on the surface, providing a silky feel without being sticky or heavy.
Pros
Gentle on skin
Its large molecular size means it stays on the surface, reducing the risk of irritation or breakouts, making it suitable for sensitive skin.
Lightweight texture
Provides a silky, non-greasy feel that improves the sensory experience of creams and serums without leaving a heavy residue.
Cons and cautions
Synthetic origin
Made from petrochemical-derived materials, which may be a concern for those seeking natural or sustainable beauty products.
Limited research
Fewer independent studies exist on this specific ingredient compared to more common emollients like squalane or jojoba oil, so long-term data is less robust.
Best for
- People with normal to dry skin seeking lightweight moisture
- Those with sensitive or acne-prone skin looking for a non-comedogenic emollient
Use caution if
- Individuals who prefer exclusively natural or plant-based ingredients
