PEG-10 Hydrogenated Lanolin

INCI: PEG-10 Hydrogenated Lanolin

A gentle, lanolin-based emollient that helps soften skin and stabilize formulas, but may clog pores for some.

In plain English

PEG-10 Hydrogenated Lanolin is a modified version of lanolin (a natural oil from sheep's wool) that has been processed with PEG (polyethylene glycol) to make it more water-friendly and less sticky. In skincare, it acts as an emollient to soften and smooth the skin, and as an emulsifier to help blend oil and water ingredients together. It's often found in moisturizers, cleansers, and hair products. While it's generally well-tolerated, it can be comedogenic (pore-clogging) for some people, especially those with oily or acne-prone skin.

Quick decision guide

Useful, but context matters

PEG-10 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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging PEG-10 Hydrogenated Lanolin.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. 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

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

moderate

May be fine for many users but deserves caution if you are breakout-prone.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

A semi-synthetic ingredient created by reacting hydrogenated lanolin with polyethylene glycol (PEG). This process reduces the waxy, sticky feel of natural lanolin and improves its ability to mix with water, making it easier to formulate into modern skincare products.

How it works

As an emollient, it fills in gaps between skin cells, making the skin feel softer and smoother. As an emulsifier, it helps stabilize mixtures of oil and water, preventing them from separating. It also has mild cleansing properties, helping to remove dirt and makeup without stripping the skin.

Pros

Gentle emollient

Softens and smooths skin without the heavy, sticky feel of natural lanolin, making it comfortable for daily use.

Versatile formula helper

Works as both an emollient and emulsifier, helping to create stable, well-mixed products that feel pleasant on the skin.

Cons and cautions

Potential pore clogger

Rated as moderately comedogenic, meaning it may cause breakouts or clogged pores for those with acne-prone or oily skin.

Not vegan-friendly

Derived from lanolin, which comes from sheep's wool, so it is not suitable for vegans or those avoiding animal-derived ingredients.

Best for

  • People with dry or normal skin looking for a gentle emollient
  • Those who tolerate lanolin-based ingredients well

Use caution if

  • Individuals with acne-prone or oily skin
  • Vegans or those avoiding animal-derived ingredients

Usage tips

If you have oily or acne-prone skin, patch test before using products with this ingredient, especially on your face.
Look for it in rinse-off products like cleansers or makeup removers if you're concerned about pore clogging.
Combine with non-comedogenic moisturizers if you have combination skin.

Safety summary

PEG-10 Hydrogenated Lanolin is generally considered safe for use in cosmetics. It has a low irritation risk but a moderate comedogenic risk, meaning it may clog pores for some people. The PEG component may contain trace impurities like 1,4-dioxane, but levels are tightly regulated and typically very low in finished products.

Research notes

Research on PEG-10 Hydrogenated Lanolin is limited, but it is similar to other PEG-modified lanolin derivatives that have been reviewed by the Cosmetic Ingredient Review (CIR) panel. The CIR concluded that PEG lanolin derivatives are safe for use in cosmetics at concentrations up to 100% for some uses, though typical use levels are much lower.

Common label clues

Typical concentration
Typically 1–10% in leave-on products; up to 30% in rinse-off products
Regulatory status
Approved for use in cosmetics by the FDA and the European Commission. The Cosmetic Ingredient Review (CIR) panel has reviewed PEG lanolin derivatives and found them safe for use in cosmetics at typical concentrations.
Common uses
Moisturizers, Cleansers, Hair conditioners, Lip products, Makeup removers
Environmental note
Lanolin is a byproduct of wool production, making it a renewable resource. However, the PEG processing involves synthetic chemistry, and the ingredient is not biodegradable in all environments.

Good to know

  • PEG-10 Hydrogenated Lanolin is considered safe by major regulatory bodies when used as directed.
  • The 'PEG-10' indicates the number of ethylene oxide units added, which affects its water solubility and mildness.
