Ingredient review
Dimethicone PEG-8 Laurate
INCI: Dimethicone PEG-8 Laurate
A silicone emulsifier that helps mix oil and water, but may not suit everyone due to its synthetic nature and potential for buildup.
In plain English
Dimethicone PEG-8 Laurate is a silicone-based ingredient that helps oil and water blend together in a product. It also has mild cleansing properties and leaves a smooth, silky feel on the skin. However, because it is a silicone derivative, it can sometimes cause buildup on the skin or hair, especially with frequent use.

Quick decision guide
Useful, but context matters
Dimethicone PEG-8 Laurate 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 Dimethicone PEG-8 Laurate.
- 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 semi-synthetic compound made by attaching a polyethylene glycol (PEG) chain to dimethicone (a silicone) and lauric acid (a fatty acid from coconut or palm oil). It acts as an emulsifier and surfactant.
How it works
It reduces the surface tension between oil and water, allowing them to mix into a stable cream or lotion. It also helps spread products evenly and leaves a non-greasy, silky finish.
Pros
Effective emulsifier
Helps oil and water mix smoothly, giving creams and lotions a stable, uniform texture.
Silky finish
Leaves a smooth, non-greasy feel on the skin, which many people find pleasant under makeup or sunscreen.
Cons and cautions
Synthetic origin
Derived from silicones and PEG, which some consumers prefer to avoid in favor of natural alternatives.
Potential buildup
With frequent use, it can accumulate on the skin or hair, possibly leading to clogged pores or dullness.
Best for
- People who enjoy silicone-based textures in moisturizers and sunscreens
- Those looking for a stable, easy-to-spread formula
Use caution if
- Individuals avoiding silicones or PEG compounds
- Those with very sensitive or acne-prone skin who prefer minimal ingredients
Usage tips
Safety summary
Generally considered safe for use in cosmetics at typical concentrations. Some concerns exist around potential contamination of PEG compounds with ethylene oxide or 1,4-dioxane, but reputable manufacturers follow purification standards. Low irritation and comedogenic risk.
Research notes
Limited peer-reviewed studies specifically on Dimethicone PEG-8 Laurate. Safety assessments for similar PEG-modified silicones indicate low acute toxicity and skin irritation. The Cosmetic Ingredient Review (CIR) panel has reviewed related ingredients and found them safe as used.
Common label clues
- Typical concentration
- 1–5%
- Regulatory status
- Approved for use in cosmetics in the US (FDA), EU, and many other regions. Manufacturers are expected to follow purity guidelines for PEG compounds.
- Common uses
- Moisturizers, Sunscreens, Makeup removers, Hair conditioners
- Environmental note
- Silicone derivatives like dimethicone are not readily biodegradable and can accumulate in the environment. PEG compounds are generally biodegradable but may be derived from petrochemicals.
Good to know
- PEG-8 indicates a chain of 8 ethylene glycol units, which helps the ingredient dissolve in water.
- This ingredient is often found in makeup removers because it can help break down waterproof makeup.
