Ingredient review
PEG-10 Laurate
INCI: PEG-10 Laurate
A common synthetic emulsifier that helps mix oil and water, but may be slightly irritating for very sensitive skin.
In plain English
PEG-10 Laurate is a man-made ingredient that helps oil and water stay mixed together in products like lotions and cleansers. The 'PEG' part means it's made from polyethylene glycol, and 'laurate' comes from lauric acid, a fatty acid found in coconut oil. It's widely used because it's effective and inexpensive, but it can sometimes cause mild irritation if you have very sensitive skin.

Quick decision guide
Useful, but context matters
PEG-10 Laurate can be useful, but watch for some irritation potential.
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-10 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
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
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-10 Laurate is a synthetic compound created by reacting polyethylene glycol (PEG) with lauric acid. It belongs to a family of ingredients called PEG esters, which are valued for their ability to reduce surface tension and help oil and water blend smoothly.
How it works
In a cosmetic product, PEG-10 Laurate sits at the boundary between oil and water droplets, lowering the surface tension so they mix into a stable emulsion. This prevents the product from separating into layers and gives it a smooth, uniform texture.
Pros
Effective emulsifier
Helps oil and water blend into a stable, creamy product that doesn't separate over time.
Improves cleansing
Works as a surfactant to help remove oil-based makeup and dirt from the skin.
Cons and cautions
Potential irritation
Can be mildly irritating for people with sensitive or compromised skin, especially in high concentrations.
Synthetic origin
Made from petrochemical-derived PEG, which may not align with a natural or 'clean' beauty preference.
Best for
- People using standard lotions or cleansers
- Those looking for affordable, effective emulsifiers
Use caution if
- Individuals with very sensitive or reactive skin
- Those who prefer exclusively natural ingredients
Usage tips
Safety summary
PEG-10 Laurate is considered safe for most people at typical cosmetic concentrations. Mild irritation is possible for sensitive skin, but serious reactions are rare. Regulatory bodies like the CIR have deemed it safe for use.
Research notes
Studies on PEG esters generally indicate low toxicity and low skin penetration. The CIR panel has reviewed similar PEG compounds and concluded they are safe in cosmetics. Direct studies on PEG-10 Laurate are limited, but its safety profile is consistent with related ingredients.
Common label clues
- Typical concentration
- Usually 1–5% of the formula
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has reviewed PEG compounds and found them safe at typical use levels.
- Common uses
- Cleansers, Lotions, Creams, Makeup removers
- Environmental note
- As a synthetic PEG compound, it is not readily biodegradable and may persist in water systems. Some manufacturers are moving toward more eco-friendly alternatives.
Good to know
- PEG-10 Laurate is often found in combination with other emulsifiers to improve stability.
- The number '10' refers to the average number of ethylene glycol units in the PEG chain.
