Ingredient review
Polyglyceryl-2 Lanolin Alcohol Ether
INCI: POLYGLYCERYL-2 LANOLIN ALCOHOL ETHER
A mild, lanolin-derived emulsifier that helps blend oil and water in creams and lotions without the irritation potential of traditional lanolin.
In plain English
This ingredient is a modified version of lanolin (the natural oil from sheep's wool) that has been made water-friendly by attaching small glycerin units. It acts as a bridge between oil and water, allowing creamy products to stay smooth and stable. Unlike raw lanolin, it is less likely to cause allergic reactions or feel greasy, making it a good choice for sensitive skin formulations.

Quick decision guide
Useful, but context matters
Polyglyceryl-2 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 Polyglyceryl-2 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 emulsifier created by reacting lanolin alcohol with polyglycerin-2. It is part of the polyglyceryl ester family, known for being milder and more eco-friendly than traditional ethoxylated emulsifiers.
How it works
Its molecular structure has both oil-loving (lipophilic) and water-loving (hydrophilic) parts. When mixed into a formula, it positions itself at the interface of oil and water droplets, reducing surface tension and keeping the emulsion stable. It also deposits a thin, non-greasy film on the skin that helps lock in moisture.
Pros
Gentle emulsifier
Creates stable creams and lotions without the need for harsh surfactants, making it suitable for sensitive skin formulations.
Non-greasy feel
Leaves a silky, lightweight finish on the skin, unlike traditional lanolin which can feel heavy and sticky.
Cons and cautions
Not vegan-friendly
Derived from sheep's wool, so it is not suitable for vegan or strict plant-based skincare routines.
Allergy potential
Although milder than raw lanolin, individuals with wool allergies may still experience irritation; patch testing is recommended.
Best for
- People with dry or normal skin looking for a rich but non-greasy moisturizer
- Anyone seeking PEG-free, lanolin-based emulsifiers in their skincare
Use caution if
- Individuals with known wool or lanolin allergies should patch-test first or avoid
Usage tips
Safety summary
Generally recognized as safe for topical use at typical concentrations. Low irritation and comedogenic risk. Individuals with wool allergies should exercise caution and patch-test.
Research notes
Limited peer-reviewed studies specifically on this ingredient, but its components (polyglycerin and lanolin alcohol) are well-studied and considered safe. The Cosmetic Ingredient Review (CIR) has evaluated related polyglyceryl esters and found them safe as used.
Common label clues
- Typical concentration
- 1–5% in leave-on products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and most major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Moisturizers, Creams, Lotions, Lip balms, Hair conditioners
- Environmental note
- Derived from a renewable animal by-product (lanolin) and is biodegradable. However, it is not plant-based, which may be a consideration for eco-conscious consumers.
Good to know
- Polyglyceryl-2 lanolin alcohol ether is often used as a PEG-free alternative to ceteareth-20 or other ethoxylated emulsifiers.
- It is considered biodegradable and has a lower environmental impact than many synthetic emulsifiers.
