Ingredient review
PPG-2 Lanolin Alcohol Ether
INCI: PPG-2 Lanolin Alcohol Ether
A gentle, lanolin-derived emollient that softens skin but may be too heavy for oily or acne-prone types.
In plain English
This ingredient is a modified version of lanolin, the natural oil from sheep's wool. The modification makes it less sticky and more spreadable than plain lanolin. It works by coating the skin's surface with a thin, protective film that locks in moisture and leaves skin feeling smooth. Because it's semi-synthetic, it's more stable and less likely to cause allergic reactions than raw lanolin, but it can still feel heavy on very oily skin.

Quick decision guide
Useful, but context matters
PPG-2 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 PPG-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
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 emollient made by reacting lanolin alcohol with propylene oxide (PPG-2). It retains the moisturizing properties of lanolin but is less greasy and more compatible with modern formulations.
How it works
It forms a non-occlusive film on the skin that reduces water loss (transepidermal water loss, or TEWL — the amount of moisture that evaporates from your skin) and softens the outer layer. It also helps other ingredients spread evenly and feel smoother upon application.
Pros
Gentle moisture lock
Helps keep skin hydrated by reducing water loss, making it great for dry or winter-damaged skin.
Smoother texture
Improves the feel of creams and lotions, making them spread more easily and feel less tacky.
Cons and cautions
Potential for breakouts
Its moderate comedogenic rating means it could clog pores for some people, especially those prone to acne.
Not ideal for oily skin
Can feel heavy or greasy on very oily skin, potentially leading to a shiny appearance.
Best for
- People with dry or normal skin looking for a gentle emollient
- Those who like the feel of lanolin but want a less sticky version
Use caution if
- Individuals with very oily or acne-prone skin
- Anyone with a known allergy to lanolin or wool-derived ingredients
Usage tips
Safety summary
Generally recognized as safe for topical use. The modification reduces the allergenic potential of lanolin, but individuals with wool allergies should still exercise caution. Moderate comedogenic risk means it may not suit acne-prone skin.
Research notes
Limited direct studies on PPG-2 Lanolin Alcohol Ether, but lanolin derivatives are well-documented as effective emollients with low irritation potential. The PPG modification improves stability and reduces stickiness compared to unmodified lanolin.
Common label clues
- Typical concentration
- Typically 1–5% in leave-on products
- Regulatory status
- Approved for use in cosmetics by the FDA and the European Commission, with no concentration restrictions in leave-on products.
- Common uses
- Moisturizers, Lip products, Hair conditioners, Makeup removers
- Environmental note
- Derived from lanolin, a byproduct of wool production, making it a relatively sustainable choice when sourced responsibly.
Good to know
- This ingredient is often found in lip balms and lipsticks because it helps products glide on smoothly.
- It is considered more stable and less allergenic than raw lanolin due to the chemical modification.
