Ingredient review
PEG-10 Lanolate
INCI: PEG-10 Lanolate
A gentle emulsifier derived from lanolin that helps blend oil and water, but may be mildly comedogenic for acne-prone skin.
In plain English
PEG-10 Lanolate is a modified form of lanolin (a natural oil from sheep's wool) that has been treated with polyethylene glycol to make it water-soluble. In skincare, it acts as a bridge between oil and water, helping products feel smooth and spread easily. It also softens the skin, similar to lanolin, but is less greasy and easier to rinse off.

Quick decision guide
Useful, but context matters
PEG-10 Lanolate 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-10 Lanolate.
- 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 with ethylene oxide (PEG), resulting in a water-soluble emulsifier that retains some of lanolin's moisturizing properties.
How it works
It reduces surface tension between oil and water phases in a formula, allowing them to mix into a stable cream or lotion. It also deposits a thin film on the skin that helps lock in moisture and leaves a soft feel.
Pros
Effective emulsifier
Helps oil and water blend smoothly, giving creams and lotions a stable, pleasant texture.
Mild skin feel
Leaves skin feeling soft and conditioned without heavy greasiness, unlike pure lanolin.
Cons and cautions
Potential for clogging pores
Some users with acne-prone skin may experience breakouts due to its lanolin base.
Not vegan-friendly
Derived from sheep's wool, so it is not suitable for those avoiding animal-derived ingredients.
Best for
- People with dry or normal skin looking for gentle emulsifiers
- Those who tolerate lanolin-based ingredients well
Use caution if
- Vegans or those avoiding animal-derived ingredients
- Acne-prone individuals who find lanolin derivatives clog pores
Usage tips
Safety summary
Generally recognized as safe for topical use at typical concentrations. Rare allergic reactions possible, especially in those sensitive to lanolin. PEG impurities are controlled by manufacturing standards.
Research notes
Limited direct studies on PEG-10 Lanolate specifically, but lanolin derivatives are well-documented as safe and effective emulsifiers. Comedogenicity is anecdotal and varies by individual.
Common label clues
- Typical concentration
- 1% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions, subject to purity standards for PEG compounds.
- Common uses
- Cleansers, Moisturizers, Makeup removers, Hair conditioners
- Environmental note
- Lanolin is a byproduct of wool production, making it a renewable resource, but PEG processing involves synthetic chemistry.
Good to know
- PEG-10 Lanolate is considered safe in cosmetics at typical use levels by expert panels.
- It is less likely to cause allergic reactions than pure lanolin due to modification.
