Ingredient review
PEG-8 Dilaurate
INCI: PEG-8 Dilaurate
PEG-8 Dilaurate is a safe, widely used emulsifier that helps products feel smooth and spread easily, but it may not suit those avoiding all PEG compounds.
In plain English
PEG-8 Dilaurate is a synthetic ingredient that helps oil and water mix together in skincare products. It’s like a bridge that keeps the formula from separating, so your lotion or cleanser stays smooth and consistent. It also helps the product spread evenly on your skin and can boost the cleansing power of washes. While it’s generally considered safe, some people prefer to avoid PEGs due to concerns about potential impurities from manufacturing.

Quick decision guide
Useful, but context matters
PEG-8 Dilaurate 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 PEG-8 Dilaurate.
- 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
PEG-8 Dilaurate is a polyethylene glycol (PEG) compound combined with lauric acid, a fatty acid from coconut or palm oil. It’s a synthetic emulsifier that reduces surface tension between oil and water.
How it works
In a cosmetic product, PEG-8 Dilaurate sits at the boundary between oil and water droplets, preventing them from separating. This creates a stable, uniform texture. It also lowers the surface tension of water, helping the product spread more easily and improving the feel of cleansers and lotions.
Pros
Effective emulsifier
PEG-8 Dilaurate reliably blends oil and water, giving lotions and creams a smooth, consistent texture that doesn't separate over time.
Improves product feel
It helps products spread easily and leaves a light, non-greasy finish, making it pleasant for daily use on the face and body.
Cons and cautions
Synthetic origin
It is made from petrochemicals, which may be a concern for those seeking fully natural or plant-based skincare routines.
Potential trace impurities
Manufacturing can produce trace amounts of 1,4-dioxane, a possible carcinogen, though reputable brands purify their ingredients to safe levels set by regulators.
Best for
- Anyone using standard lotions, creams, or cleansers
- People who want a stable, non-separating formula
Use caution if
- Those who strictly avoid all PEG compounds due to personal preference or ethical sourcing concerns
Usage tips
Safety summary
PEG-8 Dilaurate is considered safe for use in cosmetics at typical concentrations. The main concern is potential contamination with 1,4-dioxane during manufacturing, but reputable suppliers and brands control for this. It has low irritation and comedogenic potential.
Research notes
The Cosmetic Ingredient Review (CIR) panel has evaluated PEG compounds and found them safe as used in cosmetics. Studies show low skin irritation and sensitization potential. No direct studies on PEG-8 Dilaurate specifically are common, but it is grouped with similar PEG esters.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions, with concentration limits for 1,4-dioxane impurities.
- Common uses
- Cleansers, Lotions, Creams, Makeup removers
- Environmental note
- PEG compounds are not readily biodegradable in all conditions, but they are generally considered low in aquatic toxicity at cosmetic use levels.
Good to know
- PEG-8 Dilaurate is considered safe by the Cosmetic Ingredient Review (CIR) panel at typical use levels.
- It is not the same as PEG-8 (a humectant) — the 'dilaurate' part adds emulsifying properties.
