Ingredient review
Bis-Polyglyceryl-3 Oxypropyl Dimethicone
INCI: BIS-(POLYGLYCERYL-3 OXYPHENYLPROPYL) DIMETHICONE
A gentle silicone emulsifier that creates silky, spreadable textures without clogging pores or causing irritation.
In plain English
This ingredient is a type of silicone that helps water and oil mix together in a product, so you get a smooth, silky cream or lotion. It sits on the surface of your skin, making it feel soft and velvety, but it doesn't sink in deeply or block pores. Think of it like a very fine, invisible glove that helps your product glide on easily.

Quick decision guide
Useful, but context matters
Bis-Polyglyceryl-3 Oxypropyl Dimethicone 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 Bis-Polyglyceryl-3 Oxypropyl Dimethicone.
- 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 modified silicone molecule with polyglyceryl groups attached. It is a semi-synthetic ingredient designed to stabilize emulsions (mixtures of water and oil) and improve the feel of skincare products.
How it works
It reduces the surface tension between water and oil, allowing them to blend into a stable, creamy texture. On the skin, it forms a thin, breathable film that smooths the surface, reduces friction, and leaves a soft, non-greasy finish.
Pros
Silky, non-greasy feel
Leaves skin feeling soft and smooth without a heavy or sticky residue, making it ideal for lightweight moisturizers and primers.
Low irritation risk
Rated as low-irritation and low-comedogenic, so it is unlikely to cause breakouts or stinging, even for sensitive skin types.
Cons and cautions
Not silicone-free
If you avoid silicones for personal or environmental reasons, this ingredient is not suitable, as it is a silicone derivative.
May feel heavy on oily skin
In high concentrations, it can feel slightly heavy or slippery on very oily skin, potentially interfering with the absorption of other products.
Best for
- People with normal to dry skin who want a smooth, elegant texture
- Those looking for a gentle emulsifier that won't clog pores
Use caution if
- Individuals who strictly avoid all silicone-based ingredients
- Those with extremely oily skin who prefer water-only gel textures
Usage tips
Safety summary
Considered safe for cosmetic use at typical concentrations. It has a low irritation and comedogenic profile, making it suitable for most skin types. No significant safety concerns have been reported in peer-reviewed literature.
Research notes
Research on this specific molecule is limited, but it is structurally similar to other well-studied silicone emulsifiers. Evidence supports its safety and efficacy as a skin-conditioning agent and emulsifier. No major clinical studies exist, but it is widely used in commercial products.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics globally, including by the FDA (US) and EU CosIng database, with no known restrictions at typical use levels.
- Common uses
- Moisturizers, Serums, Sunscreens, Makeup primers
- Environmental note
- Silicones can be persistent in the environment. Some studies suggest they may accumulate, but this specific modified silicone is considered less concerning than older types. Always check brand sustainability policies.
Good to know
- This ingredient is often used in 'silicone-free' claims? Actually, it is a silicone, so check labels carefully.
- It is compatible with most other skincare ingredients, including actives like vitamin C and retinol.
