Ingredient review
PEG-6 Laurate
INCI: PEG-6 Laurate
PEG-6 Laurate is a common emulsifier that helps mix oil and water, but may be mildly irritating for sensitive skin.
In plain English
PEG-6 Laurate is a lab-made ingredient that helps oil and water stay blended together in products like cleansers and lotions. It belongs to the PEG (polyethylene glycol) family, which are often used to improve texture and stability. While generally safe, some people with very sensitive or reactive skin may find it slightly drying or irritating, especially in high concentrations or leave-on products.

Quick decision guide
Useful, but context matters
PEG-6 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-6 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-6 Laurate is a synthetic compound made by combining lauric acid (a fatty acid from coconut or palm oil) with polyethylene glycol (PEG), a petroleum-derived polymer. It acts as an emulsifier and surfactant, meaning it helps mix ingredients that normally separate (like oil and water) and can also help cleanse the skin by lowering surface tension.
How it works
In a cosmetic formula, PEG-6 Laurate sits at the boundary between oil and water droplets, reducing surface tension so they stay mixed. This creates a smooth, stable cream or lotion. As a surfactant, it also helps lift dirt and oil from the skin's surface, making it useful in cleansers and makeup removers.
Pros
Effective emulsifier
PEG-6 Laurate reliably blends oil and water, giving lotions and creams a smooth, uniform texture that doesn't separate.
Good for cleansing
Its surfactant properties help remove excess oil, makeup, and impurities from the skin, making it useful in cleansers and makeup removers.
Cons and cautions
Potential irritant for sensitive skin
Some people with reactive or dry skin may experience mild stinging, redness, or dryness, especially in leave-on products.
Synthetic and processing concerns
As a PEG compound, it may contain trace levels of 1,4-dioxane (a potential contaminant) if not properly purified, though reputable manufacturers control for this.
Best for
- People with normal to oily skin looking for stable, affordable emulsifiers in their products
- Those using rinse-off cleansers who want effective oil and dirt removal
Use caution if
- Individuals with very sensitive, eczema-prone, or compromised skin barriers who may react to PEG compounds
Usage tips
Safety summary
PEG-6 Laurate is generally considered safe for use in cosmetics at typical concentrations. The main concern is potential skin irritation for sensitive individuals and the theoretical presence of 1,4-dioxane, which is regulated and minimized in quality products. Overall, it is a well-studied and widely used ingredient.
Research notes
Research on PEG-6 Laurate is limited but consistent with other PEG-based emulsifiers. Studies show low acute toxicity and moderate skin irritation potential. The Cosmetic Ingredient Review (CIR) panel has reviewed similar PEG compounds and found them safe when formulated to minimize impurities.
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 specific concentration restrictions. Manufacturers are expected to follow good manufacturing practices to minimize impurities.
- Common uses
- Cleansers, Lotions, Creams, Makeup removers
- Environmental note
- PEG-6 Laurate is synthetic and not readily biodegradable. Its production relies on petroleum and palm-derived lauric acid, which may have environmental impacts depending on sourcing.
Good to know
- PEG-6 Laurate is often used in combination with other emulsifiers to create a balanced formula.
- The number '6' refers to the average length of the PEG chain, which affects its water-loving properties.
