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-12 Dilaurate.
- 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-12 Dilaurate is a polyethylene glycol (PEG) compound combined with lauric acid, a fatty acid from coconut or palm oil. It is a synthetic emulsifier and surfactant.
How it works
In a cosmetic product, PEG-12 Dilaurate sits at the boundary between water and oil droplets, reducing surface tension so they can mix into a stable cream or lotion. It also helps lower the surface tension of water, making it easier to lift dirt and oil from the skin during cleansing.
Pros
Effective emulsifier
Helps oil and water blend into a smooth, stable cream or lotion, improving product feel and performance.
Low irritation potential
At typical use levels, PEG-12 Dilaurate is considered very low risk for skin irritation or allergic reactions.
Cons and cautions
Synthetic origin
It is a man-made ingredient, which may be a turn-off for those seeking natural or minimal-ingredient routines.
Manufacturing impurities possible
Like all PEGs, there is a small risk of contamination with ethylene oxide or 1,4-dioxane, though reputable manufacturers purify to safe levels.
Best for
- People using standard lotions, creams, or cleansers
- Those looking for a stable, well-mixed product texture
Use caution if
- Those who strictly avoid synthetic or PEG-based ingredients
- Individuals with known sensitivity to PEG compounds (rare)
Usage tips
Safety summary
PEG-12 Dilaurate is considered safe for use in cosmetics at typical concentrations. The main safety consideration is the potential for trace impurities like 1,4-dioxane, but reputable manufacturers purify their ingredients to meet safety standards.
Research notes
The Cosmetic Ingredient Review (CIR) panel has evaluated PEG compounds and concluded they are safe for use in cosmetics. No specific studies on PEG-12 Dilaurate were found, but its safety profile is consistent with other PEGs.
Common label clues
- Typical concentration
- Typically 0.5% to 5% of the formula
- Regulatory status
- Approved for use in cosmetics in the US (FDA), EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has reviewed PEG compounds and found them safe as used.
- Common uses
- Cleansers, Lotions, Creams, Makeup removers
- Environmental note
- PEG-12 Dilaurate is synthetic and not readily biodegradable, but it is used in low concentrations and is not considered a major environmental concern.
Good to know
- PEG-12 Dilaurate is often found in rinse-off products like cleansers and shampoos, where it helps lift dirt and oil.
- The number '12' refers to the average length of the PEG chain, which affects its water solubility and mildness.
