Ingredient review
PEG-8 Laurate
INCI: PEG-8 Laurate
PEG-8 Laurate is a gentle synthetic emulsifier that helps mix oil and water, but may be contaminated with impurities in low-quality grades.
In plain English
PEG-8 Laurate is a man-made ingredient that helps oil and water blend together in products like cleansers and lotions. It's part of the PEG family, which are created by adding ethylene oxide to fatty acids. While generally safe, some people prefer to avoid PEGs due to potential contamination concerns during manufacturing.

Quick decision guide
Useful, but context matters
PEG-8 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-8 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-8 Laurate is a polyethylene glycol ester of lauric acid, a fatty acid found in coconut oil. It is a synthetic compound produced by reacting lauric acid with approximately 8 units of ethylene oxide.
How it works
In a cosmetic product, PEG-8 Laurate acts as an emulsifier, reducing the surface tension between oil and water so they can form a stable, uniform mixture. It also has mild cleansing properties, helping to lift dirt and oil from the skin.
Pros
Effective emulsifier
PEG-8 Laurate reliably blends oil and water, giving creams and lotions a smooth, uniform texture that feels pleasant on the skin.
Low irritation risk
It is considered gentle and is unlikely to cause stinging or redness, making it suitable for many daily-use products.
Cons and cautions
Potential impurities
During manufacturing, PEG compounds can be contaminated with 1,4-dioxane, a possible carcinogen. Reputable brands purify their ingredients to remove this, but it's a concern for some consumers.
Synthetic origin
As a lab-made ingredient, it doesn't appeal to those who prefer plant-based or naturally derived alternatives in their skincare.
Best for
- People using standard cleansers and moisturizers
- Those with normal to combination skin looking for gentle emulsifiers
Use caution if
- Individuals with known sensitivity to PEG compounds
- Those seeking 100% natural or organic formulations
Usage tips
Safety summary
PEG-8 Laurate is considered safe for use in cosmetics at typical concentrations. The main safety concern is potential contamination with 1,4-dioxane, which reputable manufacturers control through purification processes. Overall, it poses low risk of irritation or comedogenicity.
Research notes
Research on PEG-8 Laurate specifically is limited, but the broader PEG family has been reviewed by safety panels. The Cosmetic Ingredient Review (CIR) has deemed many PEG compounds safe as used in cosmetics, with the caveat that impurities should be minimized.
Common label clues
- Typical concentration
- Typically 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 no concentration restrictions. However, manufacturers are encouraged to limit 1,4-dioxane levels.
- Common uses
- Cleansers, Lotions, Creams, Makeup removers
- Environmental note
- PEG compounds are generally biodegradable, but their production involves ethylene oxide, which is derived from fossil fuels.
Good to know
- PEG-8 Laurate is often used in combination with other emulsifiers to improve stability
- The number '8' refers to the average number of ethylene oxide units, which affects its water solubility
