Ingredient review
Bis-Butyldimethicone Polyglyceryl-3
INCI: BIS-BUTYLDIMETHICONE POLYGLYCERYL-3
A gentle silicone emulsifier that creates silky, non-greasy textures and is unlikely to clog pores or irritate skin.
In plain English
This ingredient is a type of silicone that helps mix water and oil in your skincare products so they stay smooth and don't separate. It leaves a lightweight, silky feel on your skin without being heavy or greasy. Because it's a larger molecule, it mostly sits on the surface and doesn't sink deep into pores, making it a good choice for people who worry about breakouts.

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 silicone compound modified with a small polyglycerol chain. It acts as an emulsifier, meaning it helps water and oil blend together in a stable formula.
How it works
It reduces the surface tension between water and oil droplets, allowing them to mix into a uniform cream or lotion. Once applied, it forms a thin, breathable film on the skin that feels smooth and helps lock in moisture without a sticky residue.
Pros
Lightweight feel
It gives products a silky, non-sticky texture that spreads easily and doesn't feel heavy on the skin.
Low irritation risk
This ingredient is considered very gentle and is unlikely to cause stinging, redness, or allergic reactions, even for sensitive skin.
Cons and cautions
Silicone concerns
Some people choose to avoid silicones due to environmental persistence or personal preference, though this ingredient is not known to clog pores.
Limited standalone benefit
It mainly improves texture and stability, so it doesn't provide active skincare benefits like hydration or anti-aging on its own.
Best for
- Anyone who wants a lightweight, non-greasy moisturizer or primer
- People with normal to combination skin looking for a smooth finish
Use caution if
- Those who strictly avoid silicones in their routine
