Ingredient review
PEG-14 Laurate
INCI: PEG-14 Laurate
A gentle synthetic emulsifier that helps mix oil and water, generally safe but may be too heavy for very oily skin in high concentrations.
In plain English
PEG-14 Laurate is a man-made ingredient that helps oil and water stay mixed together in products like lotions and cleansers. It's part of a family of PEG compounds, which are created by adding ethylene oxide to fatty acids from plant oils. In skincare, it acts as a mild detergent and helps other ingredients spread evenly on your skin. While it's considered safe at typical levels, some people prefer to avoid PEGs due to concerns about potential impurities from manufacturing.

Quick decision guide
Useful, but context matters
PEG-14 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-14 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-14 Laurate is a polyethylene glycol (PEG) derivative of lauric acid, a fatty acid found in coconut oil and palm kernel oil. It is a synthetic emulsifier and surfactant, meaning it helps mix water and oil and reduces surface tension for better spreading.
How it works
In a cosmetic product, PEG-14 Laurate sits at the boundary between oil and water droplets, keeping them from separating. This creates a stable, smooth texture. It also helps cleanse by trapping dirt and oil so they can be rinsed away.
Pros
Gentle emulsifier
Helps create stable, smooth creams and lotions without harshness, making it suitable for sensitive skin types.
Improves texture
Enhances the spreadability and feel of products, so they glide on easily and absorb well.
Cons and cautions
Potential impurity concern
During manufacturing, PEGs can be contaminated with 1,4-dioxane, a possible carcinogen. Reputable brands use purified grades to keep levels safe.
Environmental persistence
PEG compounds are not readily biodegradable, which raises concerns about their accumulation in waterways.
Best for
- People with normal to dry skin looking for gentle cleansers
- Those who prefer stable, non-separating lotions and creams
Use caution if
- Individuals with very oily or acne-prone skin who may find PEG-14 Laurate too emollient
- Anyone strictly avoiding all PEG compounds for personal or environmental reasons
Usage tips
Safety summary
PEG-14 Laurate is considered safe for use in cosmetics at typical concentrations. The main concern is potential contamination with 1,4-dioxane, but purified grades used by reputable brands keep levels well below safety limits. It is generally non-irritating and non-comedogenic.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have concluded that PEG compounds are safe as used in cosmetics when manufactured to purity standards. Studies show low acute toxicity and minimal skin irritation. Environmental data indicate low biodegradability.
Common label clues
- Typical concentration
- Typically 0.5% to 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 typically under 10% in leave-on products.
- Common uses
- Cleansers, Lotions, Creams, Makeup removers
- Environmental note
- PEG-14 Laurate is synthetic and not readily biodegradable. Some manufacturers are moving toward bio-based or biodegradable alternatives.
Good to know
- PEG numbers (like 14) indicate the average number of ethylene oxide units, which affects water solubility and mildness
- PEG-14 Laurate is often used alongside other emulsifiers for best stability
