Ingredient review
PEG-75 Lanolin Wax
INCI: PEG-75 Lanolin Wax
A gentle, water-friendly emollient that helps soften skin and stabilize formulas, but may clog pores for some.
In plain English
PEG-75 Lanolin Wax is a modified version of lanolin, the natural oil from sheep's wool. The PEG (polyethylene glycol) part makes it mixable with water, so it spreads easily and feels less greasy than plain lanolin. It helps moisturize by forming a light film that locks in hydration, and it also helps other ingredients blend together smoothly.

Quick decision guide
Useful, but context matters
PEG-75 Lanolin Wax 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-75 Lanolin Wax.
- 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 ingredient created by reacting lanolin wax with ethylene oxide (PEG). This process makes the naturally waxy, water-repellent lanolin water-soluble and easier to rinse off.
How it works
It sits on the skin's surface to reduce water loss (like a gentle barrier) and helps oil and water ingredients mix in a formula, creating a stable, creamy texture.
Pros
Water-friendly emollient
Unlike plain lanolin, PEG-75 Lanolin Wax rinses off easily and feels lighter, making it more pleasant in lotions and cleansers.
Formula stabilizer
It helps keep oil and water mixed, so your product stays smooth and doesn't separate over time.
Cons and cautions
Potential pore clogger
Rated moderate on the comedogenic scale, it may cause breakouts or clogged pores for those with oily or acne-prone skin.
Animal-derived origin
Since it comes from sheep's wool, it is not vegan and may not suit those avoiding animal ingredients.
Best for
- People with dry or normal skin looking for a gentle emollient
- Those who tolerate lanolin derivatives well
Use caution if
- Individuals with known wool or lanolin allergies
- Acne-prone skin that clogs easily
Usage tips
Safety summary
Generally safe for most people when used in cosmetics. The main concerns are potential comedogenicity and rare allergic reactions in those sensitive to lanolin. The PEG modification reduces irritation potential.
Research notes
The Cosmetic Ingredient Review (CIR) panel reviewed PEGylated lanolin derivatives and concluded they are safe in current usage patterns. No significant toxicity or irritation was found in standard tests.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The CIR panel has deemed it safe as used in rinse-off and leave-on products.
- Common uses
- Moisturizers, Cleansers, Hair conditioners, Body lotions, Makeup removers
- Environmental note
- Lanolin is a byproduct of wool production, making it a renewable resource. However, the PEG process involves synthetic chemistry and may have environmental considerations regarding biodegradability.
Good to know
- PEG-75 Lanolin Wax is considered safe by the Cosmetic Ingredient Review (CIR) panel at typical use levels.
- The PEG modification reduces the risk of allergic reaction compared to raw lanolin, but it is not zero-risk.
