Ingredient review
PPG-12-PEG-50 Lanolin
INCI: PPG-12-PEG-50 Lanolin
A versatile, low-irritation lanolin derivative that helps blend oil and water while softening skin.
In plain English
PPG-12-PEG-50 Lanolin is a modified version of lanolin (the natural oil from sheep's wool). The modification makes it water-soluble and less likely to cause allergic reactions than plain lanolin. It works as both an emollient (softens skin) and an emulsifier (helps oil and water mix), so it's often used in creamy cleansers and moisturizers to create a smooth texture and leave skin feeling soft.

Quick decision guide
Useful, but context matters
PPG-12-PEG-50 Lanolin 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 PPG-12-PEG-50 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
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 made by adding ethylene oxide and propylene oxide chains to lanolin, transforming it into a water-soluble, low-irritation emulsifier and skin conditioner.
How it works
It reduces surface tension between oil and water, allowing them to blend into a stable cream or lotion. At the same time, it deposits a thin, non-greasy film on the skin that helps lock in moisture and smooth the surface.
Pros
Gentle on skin
The modification reduces the allergenic potential of lanolin, making it suitable for most skin types, including sensitive skin.
Versatile texture
It helps create smooth, creamy products that spread easily and leave skin feeling soft without a heavy, sticky residue.
Cons and cautions
Ethoxylation concerns
The manufacturing process can create trace amounts of 1,4-dioxane, a potential contaminant, though reputable brands purify their ingredients to safe levels.
Not for lanolin-allergic individuals
Despite lower risk, people with a known lanolin allergy may still react, especially at higher concentrations.
Best for
- People with dry or normal skin looking for a gentle emulsifier in moisturizers
- Those who want a lanolin-based ingredient with lower allergy risk than plain lanolin
Use caution if
- Individuals with a confirmed allergy to lanolin or wool alcohols
- Those who prefer completely natural or non-ethoxylated ingredients
Usage tips
Safety summary
PPG-12-PEG-50 Lanolin is considered safe for cosmetic use at typical concentrations. The main safety consideration is the potential for trace 1,4-dioxane contamination, which is regulated and minimized by quality manufacturers. Allergic reactions are rare but possible in individuals sensitive to lanolin.
Research notes
The Cosmetic Ingredient Review (CIR) panel has evaluated PEGylated lanolin derivatives and found them safe for use in cosmetics. Studies show that ethoxylation reduces the allergenicity of lanolin, making it a milder alternative. No significant human or environmental toxicity has been reported at cosmetic use levels.
Common label clues
- Typical concentration
- 1% to 10% in rinse-off products; 0.5% to 5% in leave-on products
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) with no concentration restrictions, though manufacturers are encouraged to minimize 1,4-dioxane impurities.
- Common uses
- Moisturizers, Cleansers, Makeup removers, Hair conditioners
- Environmental note
- Lanolin is a byproduct of wool production, making it a renewable resource. However, the ethoxylation process is energy-intensive and may involve chemicals of environmental concern.
Good to know
- This ingredient is often used in 'water-soluble' lanolin products, making it easier to rinse off than plain lanolin.
- The 'PPG-12' and 'PEG-50' parts refer to the number of propylene oxide and ethylene oxide units added, which determine its water solubility and mildness.
