Ingredient review
PEG-16 Lanolin Alcohol Ether
INCI: PEG-16 Cetyl/Oleyl/Stearyl/Lanolin Alcohol Ether
A gentle emulsifier derived from lanolin that helps blend oil and water, but may be slightly comedogenic for acne-prone skin.
In plain English
This ingredient is a modified version of lanolin alcohol (a natural wax from sheep's wool) that has been made water-friendly by adding PEG chains. It acts like a bridge between oil and water, helping creams and lotions stay mixed and feel smooth on the skin. Because it's derived from lanolin, it can be very moisturizing but might clog pores for some people.

Quick decision guide
Useful, but context matters
PEG-16 Lanolin Alcohol Ether can be useful, but watch for possible clogging concerns.
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-16 Lanolin Alcohol Ether.
- 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
moderateMay be fine for many users but deserves caution if you are breakout-prone.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic compound created by reacting lanolin alcohol with ethylene oxide (PEG-16). It retains the emollient properties of lanolin while gaining water solubility, making it useful in rinse-off and leave-on products.
How it works
In a formula, the PEG chain attracts water while the fatty alcohol part attracts oil. This allows it to stabilize emulsions (mixtures of oil and water) and help other ingredients spread evenly. It also deposits a thin, moisturizing film on the skin or hair.
Pros
Effective emulsifier
Stabilizes oil-and-water mixtures, giving creams and lotions a smooth, uniform texture that feels pleasant on the skin.
Mild moisturizing
Retains some of lanolin's emollient properties, helping to soften and condition the skin without heavy greasiness.
Cons and cautions
Potential comedogenicity
May clog pores in some individuals, especially those with acne-prone or oily skin, so patch testing is wise.
Not vegan-friendly
Derived from lanolin (sheep's wool), so it is not suitable for vegans or those avoiding animal-derived ingredients.
Best for
- People with dry or normal skin looking for a gentle emulsifier
- Those who tolerate lanolin-based ingredients well
Use caution if
- Individuals with known lanolin allergy or sensitivity
- Those with very oily or acne-prone skin who prefer non-comedogenic products
Usage tips
Safety summary
Generally safe for most people when used as directed. The main concerns are potential comedogenicity and allergy in those sensitive to lanolin. PEG compounds are well-studied and considered low-risk in cosmetics.
Research notes
Lanolin derivatives have a long history of safe use in cosmetics. PEG ethers are widely used as emulsifiers. There is limited specific research on PEG-16 lanolin alcohol ether, but the class is well-tolerated. Comedogenicity is anecdotal and varies by individual.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. The PEG chain is generally considered safe at typical concentrations.
- Common uses
- Moisturizers, Cleansers, Hair conditioners, Makeup removers
- Environmental note
- PEG compounds can be persistent in the environment, but this ingredient is used in small amounts and is not considered a major pollutant.
Good to know
- PEG-16 indicates the average number of ethylene oxide units in the chain, which affects water solubility.
- This ingredient is often used in combination with other emulsifiers to create a balanced formula.
