Ingredient review
PEG-75 Laurate
INCI: PEG-75 Laurate
A gentle synthetic emulsifier that helps mix water and oil, but may not suit those avoiding ethoxylated ingredients.
In plain English
PEG-75 Laurate is a man-made ingredient that helps water and oil blend together in products like cleansers and lotions. It's part of the PEG (polyethylene glycol) family, which are widely used to improve texture and stability. While generally considered safe at low levels, some people prefer to avoid PEGs due to concerns about potential impurities from manufacturing.

Quick decision guide
Useful, but context matters
PEG-75 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-75 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-75 Laurate is a synthetic compound made by reacting lauric acid (a fatty acid from coconut or palm oil) with ethylene oxide. The '75' refers to the average number of ethylene oxide units, which determines its water-loving properties.
How it works
It works as an emulsifier, reducing the surface tension between oil and water so they can mix into a stable, creamy product. It also acts as a mild surfactant, helping to lift dirt and oil from the skin during cleansing.
Pros
Effective emulsifier
Creates stable, smooth lotions and creams that feel pleasant on the skin.
Low irritation potential
Generally well-tolerated and unlikely to cause redness or stinging, even on sensitive skin.
Cons and cautions
Ethoxylation concerns
The manufacturing process can produce trace amounts of 1,4-dioxane, a potential carcinogen, though reputable brands purify their ingredients.
Not eco-friendly
PEG compounds can be slow to biodegrade and may accumulate in the environment.
Best for
- People with normal to combination skin
- Those looking for gentle, non-stripping cleansers
Use caution if
- Individuals who prefer to avoid ethoxylated ingredients
- Those with known sensitivity to PEG compounds
Usage tips
Safety summary
PEG-75 Laurate is considered safe for cosmetic use at typical concentrations. The main concern is potential contamination with 1,4-dioxane during manufacturing, but reputable suppliers use purification steps to keep levels well below safety limits.
Research notes
Studies show PEGs are generally non-irritating and non-sensitizing. The Cosmetic Ingredient Review (CIR) panel has deemed many PEGs safe as used in cosmetics, with the caveat that impurities should be minimized.
Common label clues
- Typical concentration
- 1–5% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics by the FDA and EU CosIng database, with concentration limits in some regions.
- Common uses
- Cleansers, Lotions, Creams, Makeup removers
- Environmental note
- PEG compounds are not readily biodegradable and may persist in water systems, though some treatment plants can break them down.
Good to know
- PEG-75 Laurate is often used in combination with other emulsifiers for better stability.
- The number '75' indicates the polymer chain length, which affects how water-soluble the ingredient is.
