Ingredient review
Lauryl PEG-8 PPG-8 Dimethicone
INCI: LAURYL PEG-8 PPG-8 DIMETHICONE
A gentle silicone emulsifier that helps create smooth, spreadable formulas without a greasy feel.
In plain English
This is a silicone-based ingredient that acts like a bridge between water and oil in a product. It helps mix ingredients that normally don't blend well, giving creams and lotions a silky, lightweight texture that spreads easily on skin or hair. It also leaves a soft, non-sticky finish.

Quick decision guide
Useful, but context matters
Lauryl PEG-8 PPG-8 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 Lauryl PEG-8 PPG-8 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 polyethylene glycol (PEG) and polypropylene glycol (PPG) chains attached. It is a semi-synthetic emulsifier designed to stabilize water-in-oil or oil-in-water emulsions.
How it works
The PEG and PPG portions make the silicone more water-friendly, allowing it to sit at the boundary between water and oil droplets. This prevents the formula from separating and gives the product a uniform, smooth consistency. On skin, it forms a thin, breathable film that feels silky and helps other ingredients spread evenly.
Pros
Lightweight feel
Unlike some heavy oils or waxes, this silicone emulsifier gives a silky, barely-there texture that doesn't clog pores or feel sticky.
Stable formulas
It helps keep water and oil mixed together, so your product stays smooth and effective from first use to last.
Cons and cautions
Silicone concerns
Some people choose to avoid silicones for environmental or personal preference reasons, and this ingredient is a silicone derivative.
PEG controversy
PEG compounds can sometimes contain trace impurities like ethylene oxide during manufacturing, though cosmetic-grade versions are purified and considered safe at low levels.
Best for
- People who prefer lightweight, non-greasy moisturizers
- Those with normal to combination skin looking for smooth makeup or sunscreen application
Use caution if
- Individuals who strictly avoid silicones in their routine
- Those with known sensitivity to PEG compounds
Usage tips
Safety summary
Lauryl PEG-8 PPG-8 Dimethicone is considered safe for cosmetic use at typical concentrations. It has low irritation and comedogenic potential. The main concerns are related to silicone persistence and PEG impurities, but regulatory bodies deem it safe when properly manufactured.
Research notes
The Cosmetic Ingredient Review (CIR) panel has evaluated similar PEG/PPG dimethicone copolymers and found them safe in cosmetic formulations. No significant human or animal toxicity has been reported at use levels. Most evidence comes from safety assessments rather than efficacy studies.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics globally, including by the FDA (as part of cosmetic ingredients) and the EU CosIng database. The CIR panel has reviewed it and found it safe as used.
- Common uses
- Moisturizers, Sunscreens, Foundations, Hair conditioners
- Environmental note
- Silicones can be slow to biodegrade in the environment. Some manufacturers are moving toward more biodegradable alternatives, but this ingredient is still widely used.
Good to know
- This ingredient is often found in 'water-in-silicone' emulsions, which are popular in long-wear makeup and sunscreens.
- It is considered safe by the Cosmetic Ingredient Review (CIR) panel at typical use concentrations.
