Ingredient review
PEG-75 Sorbitan Lanolate
INCI: PEG-75 SORBITAN LANOLATE
A gentle, water-soluble emulsifier derived from lanolin that helps blend oil and water in creams and cleansers, with a low risk of irritation.
In plain English
PEG-75 Sorbitan Lanolate is a modified version of lanolin (a natural oil from sheep's wool) that has been made water-soluble. It acts as a bridge between oil and water, allowing them to mix into a smooth cream or lotion. It also helps soften and condition the skin, similar to lanolin, but without the heavy, greasy feel.

Quick decision guide
Useful, but context matters
PEG-75 Sorbitan Lanolate 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 PEG-75 Sorbitan 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
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 ingredient created by reacting lanolin with ethylene oxide and sorbitan. It is a waxy, water-soluble emulsifier that helps stabilize oil-in-water emulsions.
How it works
It reduces the surface tension between oil and water, allowing them to blend into a stable, uniform cream or lotion. It also deposits a thin, moisturizing film on the skin, helping to reduce water loss and improve skin softness.
Pros
Gentle emulsifier
It helps blend oil and water into a smooth cream without causing irritation, making it suitable for sensitive skin formulations.
Non-greasy feel
Unlike pure lanolin, this water-soluble version rinses off easily and leaves skin soft without a heavy, sticky residue.
Cons and cautions
Potential contaminant concern
The ethoxylation process used to create this ingredient can leave trace amounts of 1,4-dioxane, a possible carcinogen, though levels are typically very low and regulated.
Not vegan-friendly
Since it is derived from lanolin (sheep's wool), it is not suitable for those following a vegan lifestyle.
Best for
- People with dry or normal skin looking for gentle moisturizers
- Those who prefer water-soluble, non-greasy cleansers and lotions
Use caution if
- Individuals with known lanolin allergy
- Vegans or those avoiding animal-derived ingredients
Usage tips
Safety summary
PEG-75 Sorbitan Lanolate is considered safe for use in cosmetics at typical concentrations. The main safety consideration is the potential for trace 1,4-dioxane contamination, but levels are tightly controlled by manufacturers and regulators. It has a low irritation and comedogenic risk.
Research notes
The Cosmetic Ingredient Review (CIR) panel reviewed PEGylated lanolin derivatives and concluded they are safe as used in cosmetics. No significant new research has emerged to challenge this conclusion. Most data comes from industry safety assessments rather than independent clinical trials.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has deemed it safe as used in rinse-off and leave-on products.
- Common uses
- Moisturizers, Cleansers, Makeup removers, Body lotions
- Environmental note
- Derived from lanolin, a byproduct of wool production, which is a renewable resource. However, the ethoxylation process involves ethylene oxide, which is produced from fossil fuels.
Good to know
- PEG-75 Sorbitan Lanolate is often used in makeup removers because it can dissolve both oil-based and water-based impurities.
- It is considered safe by the Cosmetic Ingredient Review (CIR) panel at typical use levels.
