Ingredient review
PEG-6 Dilaurate
INCI: PEG-6 Dilaurate
PEG-6 Dilaurate is a gentle synthetic emulsifier that helps mix water and oil in your products, but it may not be ideal for very sensitive or compromised skin.
In plain English
PEG-6 Dilaurate is a man-made ingredient that helps oil and water stay blended in your skincare products, so they don't separate on the shelf. It's a type of polyethylene glycol (PEG) combined with lauric acid, a fatty acid from coconut or palm oil. In your cleanser or lotion, it works to create a smooth, even texture and helps remove makeup and dirt when you rinse. It's generally considered safe and mild, but because it's a PEG compound, there are purity concerns if the raw material isn't well-processed.

Quick decision guide
Useful, but context matters
PEG-6 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-6 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-6 Dilaurate is a synthetic compound made by reacting polyethylene glycol (PEG) with lauric acid. It belongs to a family of ingredients called PEG esters, which are widely used in cosmetics as emulsifiers and surfactants.
How it works
In a cosmetic formula, PEG-6 Dilaurate sits at the boundary between oil and water droplets, reducing surface tension so they mix into a stable emulsion. This gives creams and lotions their smooth, uniform consistency. In cleansers, it helps lift oil-based impurities from the skin so they can be rinsed away with water.
Pros
Effective emulsifier
PEG-6 Dilaurate reliably blends oil and water, giving your creams and lotions a smooth, stable texture that doesn't separate.
Gentle cleansing
It helps remove makeup and excess oil without stripping the skin, making it suitable for daily use in rinse-off cleansers.
Cons and cautions
Purity concerns
As a PEG derivative, it may contain trace impurities like ethylene oxide or 1,4-dioxane if not manufactured to high standards, though reputable brands ensure proper purification.
Potential dryness
In leave-on products or with frequent use, it can be slightly drying for those with already dry or sensitive skin.
Best for
- People with normal to oily skin looking for a gentle cleanser or lotion
- Anyone using rinse-off products like face washes or makeup removers
Use caution if
- Individuals with very dry, irritated, or compromised skin barriers may prefer non-PEG emulsifiers
Usage tips
Safety summary
PEG-6 Dilaurate is considered safe for cosmetic use at typical concentrations. The main safety consideration is the potential for contamination with ethylene oxide or 1,4-dioxane during manufacturing, but reputable suppliers ensure these impurities are removed. It has low irritation and comedogenic potential.
Research notes
Studies on PEG esters indicate they are mild and well-tolerated on skin. The Cosmetic Ingredient Review (CIR) panel has evaluated similar PEG compounds and found them safe for use in cosmetics. No specific long-term studies on PEG-6 Dilaurate alone are widely available.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics by the FDA and the European Commission, with concentration limits typically not specified due to its low irritation profile.
- Common uses
- Cleansers, Lotions, Creams, Makeup removers
- Environmental note
- PEG compounds are generally biodegradable, but their production relies on petrochemicals, which have a higher environmental footprint than some plant-based alternatives.
Good to know
- PEG-6 Dilaurate is considered safe by major regulatory bodies when used as directed in cosmetics
- Look for products from brands that disclose purity testing to avoid contamination concerns
