Ingredient review
PPG-20-PEG-20 Hydrogenated Lanolin
INCI: PPG-20-PEG-20 Hydrogenated Lanolin
A versatile, semi-synthetic emollient that softens skin and helps blend oil and water, but may clog pores for some.
In plain English
This ingredient is a modified version of lanolin, a natural oil from sheep's wool. The modification makes it less sticky and more water-friendly, so it spreads easily in lotions and creams. It works by coating the skin with a thin, protective film that locks in moisture and leaves a smooth feel. However, because it is oil-based, it can clog pores in people prone to acne.

Quick decision guide
Useful, but context matters
PPG-20-PEG-20 Hydrogenated Lanolin 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-20-PEG-20 Hydrogenated Lanolin.
- 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
PPG-20-PEG-20 Hydrogenated Lanolin is a semi-synthetic polymer created by adding ethylene oxide and propylene oxide to hydrogenated lanolin. This process makes the lanolin more water-soluble and less greasy, improving its feel in cosmetic formulations.
How it works
It acts as both an emollient (softening and smoothing the skin) and an emulsifier (helping oil and water mix together). The PPG and PEG chains allow it to attract water while still providing the moisturizing benefits of lanolin, creating stable, creamy products.
Pros
Effective moisturizer
Forms a protective film that reduces water loss, keeping skin soft and hydrated for hours.
Versatile formulator
Works as both an emollient and emulsifier, making it useful in many product types from creams to cleansers.
Cons and cautions
Potential pore clogger
Rated as moderately comedogenic, meaning it can cause breakouts in acne-prone individuals.
Not vegan-friendly
Derived from lanolin (sheep's wool), so it is not suitable for those avoiding animal products.
Best for
- People with dry or normal skin looking for rich moisture
- Those who tolerate lanolin derivatives well
Use caution if
- Individuals with very oily or acne-prone skin
- Vegans or those avoiding animal-derived ingredients
Usage tips
Safety summary
Generally considered safe for most skin types when used as directed. The main concern is potential comedogenicity for acne-prone skin. Rare allergic reactions may occur in individuals sensitive to lanolin.
Research notes
Studies on modified lanolin derivatives show good skin tolerance and moisturizing efficacy. The ingredient has a long history of safe use in cosmetics, though individual sensitivity varies.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Moisturizers, Cleansers, Hair conditioners, Lip products, Makeup removers
- Environmental note
- Derived from a renewable animal source (sheep's wool), but the ethoxylation process involves synthetic chemistry. Not biodegradable in all conditions.
Good to know
- The PPG and PEG modification reduces the strong lanolin scent and stickiness.
- It is often found in makeup removers because it can dissolve both oil- and water-based impurities.
