Ingredient review
PEG-2 Laurate
INCI: PEG-2 Laurate
A gentle emulsifier that helps mix water and oil in skincare products, generally well-tolerated but not a star active ingredient.
In plain English
PEG-2 Laurate is a synthetic ingredient that helps water and oil blend together in creams, lotions, and cleansers. It's a type of polyethylene glycol (PEG) combined with lauric acid, a fatty acid found in coconut oil. In a formula, it acts like a bridge between water-loving and oil-loving ingredients, creating a smooth, stable texture. It's considered very mild and unlikely to irritate skin, but it doesn't provide any direct skin benefits like hydration or anti-aging.

Quick decision guide
Useful, but context matters
PEG-2 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 PEG-2 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
PEG-2 Laurate is a polyethylene glycol ester of lauric acid, created by reacting lauric acid with about 2 units of ethylene oxide. It functions primarily as an emulsifier and surfactant in cosmetic products.
How it works
It reduces the surface tension between oil and water, allowing them to mix into a stable emulsion. This prevents creams and lotions from separating and gives cleansers their ability to lift dirt and oil from the skin.
Pros
Gentle emulsifier
PEG-2 Laurate is very mild on skin, making it suitable for daily-use cleansers and moisturizers even for sensitive skin.
Improves product texture
It helps create a smooth, non-greasy feel in creams and lotions, enhancing the user experience.
Cons and cautions
No active skin benefit
This ingredient only helps with formula stability and texture; it doesn't hydrate, soothe, or protect the skin on its own.
Potential trace impurities
As a PEG compound, it may contain trace amounts of 1,4-dioxane from manufacturing, though reputable brands purify it to safe levels.
Best for
- Anyone using standard creams, lotions, or cleansers
- People with normal to dry skin looking for stable, gentle formulas
Use caution if
- Those with known sensitivity to PEG compounds (rare)
- People seeking purely natural or plant-based cosmetics
Usage tips
Safety summary
PEG-2 Laurate is considered safe for use in cosmetics at typical concentrations. The main concern is potential contamination with 1,4-dioxane, a byproduct of PEG manufacturing, but reputable manufacturers purify the ingredient to meet safety standards. Skin irritation and allergy are very rare.
Research notes
The Cosmetic Ingredient Review (CIR) has reviewed PEG compounds and found them safe for cosmetic use. No specific studies on PEG-2 Laurate alone were identified, but its safety profile is consistent with similar PEG esters. Evidence is moderate and based on analogy to related ingredients.
Common label clues
- Typical concentration
- 0.5–5%
- Regulatory status
- Approved for use in cosmetics in the US (FDA), EU, and other major markets. The Cosmetic Ingredient Review (CIR) panel has deemed PEG compounds safe as used in cosmetics when properly purified.
- Common uses
- Cleansers, Lotions, Creams, Makeup removers
- Environmental note
- PEG-2 Laurate is synthetic and derived from petroleum and plant-based lauric acid. It is not readily biodegradable in all conditions, but its environmental impact is considered low at typical usage levels.
Good to know
- PEG-2 Laurate is often used alongside other emulsifiers to create a more stable formula.
- It is not a preservative, so products containing it still need a proper preservation system.
