Ingredient review
PEG/PPG-23/6 Dimethicone
INCI: PEG/PPG-23/6 Dimethicone
A gentle silicone emulsifier that improves texture and spreadability without clogging pores or causing irritation.
In plain English
PEG/PPG-23/6 Dimethicone is a modified silicone that acts like a bridge between water and oil in a product. It helps create smooth, even creams and lotions that feel silky on your skin, not greasy. Because it's a silicone, it also leaves a light, invisible film that can help your skin feel soft and help makeup last longer.

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 PEG/PPG-23/6 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 silicone-based copolymer (PEG/PPG-23/6 Dimethicone) that combines water-loving (PEG/PPG) and oil-loving (dimethicone) parts, making it an effective emulsifier and skin-conditioning agent.
How it works
It reduces surface tension between water and oil phases, allowing them to mix into a stable emulsion. Once applied, it forms a thin, breathable film on the skin that smooths texture, reduces water loss, and provides a silky feel without heavy residue.
Pros
Excellent texture enhancer
Creates a silky, non-greasy feel that makes creams and lotions glide on smoothly, improving the user experience.
Low irritation potential
Rated low on both irritation and comedogenic scales, making it suitable for sensitive and acne-prone skin types.
Cons and cautions
Silicone-based ingredient
Some users prefer to avoid silicones due to personal preference or concerns about buildup on the skin.
May require double cleansing
The film-forming nature can make it resistant to water-only rinsing, so an oil-based cleanser may be needed for thorough removal.
Best for
- People who want a smooth, silky finish in moisturizers or makeup
- Those with normal to combination skin looking for lightweight hydration
Use caution if
- Individuals who prefer silicone-free skincare routines
- Those with very oily skin who may find silicones too occlusive
