Ingredient review
PEG-30 Hydrogenated Lanolin
INCI: PEG-30 Hydrogenated Lanolin
A gentle emulsifier that helps blend oil and water in creams, but may clog pores in acne-prone skin.
In plain English
PEG-30 Hydrogenated Lanolin is a modified version of lanolin (a waxy substance from sheep's wool). The modification makes it less sticky and more water-friendly, so it can help mix oils and water in your lotions and creams. It also leaves a soft, smooth feel on skin, but because it's still related to lanolin, it might be too heavy for oily or acne-prone skin.

Quick decision guide
Useful, but context matters
PEG-30 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 PEG-30 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
A semi-synthetic ingredient made by reacting hydrogenated lanolin with ethylene oxide (PEG). This process creates a water-soluble emulsifier that is milder and less greasy than raw lanolin.
How it works
It sits at the boundary between oil and water in a formula, reducing surface tension so the two phases blend into a stable cream or lotion. It also deposits a thin, moisturizing film on skin to reduce water loss.
Pros
Effective emulsifier
Stabilizes oil-and-water blends so your creams and lotions have a smooth, consistent texture.
Skin conditioning
Leaves a soft, non-greasy film that helps maintain moisture, making it useful for dry skin products.
Cons and cautions
Potential pore clogging
Because it is derived from lanolin, it may clog pores in acne-prone or oily skin, leading to breakouts.
PEG processing concerns
The PEG (polyethylene glycol) part can sometimes contain trace impurities like ethylene oxide or 1,4-dioxane, though reputable manufacturers purify their ingredients.
Best for
- People with dry or normal skin looking for a rich moisturizer
- Those who tolerate lanolin derivatives well
Use caution if
- Individuals with known lanolin allergy
- Acne-prone or oily skin types who may experience clogged pores
Usage tips
Safety summary
Generally recognized as safe for most skin types when used in properly formulated cosmetics. The main concerns are potential comedogenicity and rare allergic reactions in individuals sensitive to lanolin. PEG impurities are minimized by quality manufacturing.
Research notes
Limited direct studies on PEG-30 Hydrogenated Lanolin, but lanolin derivatives are well-documented as safe skin conditioners. The Cosmetic Ingredient Review (CIR) panel has reviewed PEGylated lanolin derivatives and found them safe for cosmetic use.
Common label clues
- Typical concentration
- 1% to 5%
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) with no specific concentration restrictions, though manufacturers are expected to ensure purity.
- Common uses
- Moisturizers, Cleansers, Makeup removers, Hair conditioners
- Environmental note
- Lanolin is a byproduct of wool production, making it a renewable resource. However, the PEG modification involves synthetic chemistry that may have a higher environmental footprint.
Good to know
- PEG-30 Hydrogenated Lanolin is considered safer and less allergenic than raw lanolin because the modification reduces protein residues that can trigger allergies.
- The number '30' refers to the average number of ethylene oxide units added, which affects water solubility.
