Ingredient review
PPG-20 Lanolin Alcohol Ether
INCI: PPG-20 Lanolin Alcohol Ether
A gentle, lanolin-derived emollient that softens skin and hair without the heavy feel of pure lanolin.
In plain English
PPG-20 Lanolin Alcohol Ether is a modified version of lanolin alcohol, a natural waxy substance from sheep's wool. The PPG-20 part means it has been chemically altered to be lighter and less greasy than pure lanolin. In skincare and haircare, it works as an emollient, meaning it fills in the gaps between skin cells to smooth and soften the surface. It also helps other ingredients spread more evenly and can reduce water loss from the skin, keeping it hydrated longer. Because it's less likely to clog pores than pure lanolin, it's often used in products for normal to dry skin types.

Quick decision guide
Useful, but context matters
PPG-20 Lanolin Alcohol Ether 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 PPG-20 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
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
A semi-synthetic emollient made by reacting lanolin alcohol with propylene oxide (PPG-20). This process creates a lighter, more spreadable ingredient that retains the moisturizing benefits of lanolin but with a less greasy feel.
How it works
It forms a thin, breathable film on the skin or hair surface, which helps lock in moisture and smooth rough texture. It also reduces friction, making products feel silky and easy to apply.
Pros
Lightweight emollience
Provides the moisturizing benefits of lanolin without the heavy, greasy feel, making it suitable for lotions and creams that absorb quickly.
Low irritation potential
Generally well-tolerated even on sensitive skin, with a low risk of irritation or clogging pores compared to pure lanolin.
Cons and cautions
Not vegan-friendly
Derived from lanolin, which comes from sheep's wool, so it is not suitable for those following a strict vegan lifestyle.
Rare allergy risk
A small number of people with wool alcohol allergies may experience contact dermatitis, so patch testing is advised for sensitive individuals.
Best for
- People with dry or normal skin looking for a gentle emollient
- Those who want a lanolin-like benefit without the heavy texture
Use caution if
- Individuals with a known allergy to lanolin or wool alcohols
- Strict vegans who avoid animal-derived ingredients
Usage tips
Safety summary
PPG-20 Lanolin Alcohol Ether is considered safe for cosmetic use with a low risk of irritation or comedogenicity. Rare allergic reactions may occur in individuals sensitive to lanolin.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have concluded that lanolin alcohol derivatives are safe in cosmetics. Specific studies on PPG-20 Lanolin Alcohol Ether are limited, but its chemical class is well-established as gentle and effective.
