PEG-6 Lanolate

INCI: PEG-6 Lanolate

A gentle, lanolin-derived emollient that helps moisturize and stabilize products, but may be comedogenic for some.

In plain English

PEG-6 Lanolate is a modified form of lanolin (the natural oil from sheep's wool) that has been processed with polyethylene glycol to make it more water-friendly and less greasy. In skincare, it acts as an emollient to soften the skin and as an emulsifier to help oil and water mix smoothly. It's often found in moisturizers, cleansers, and bar soaps. While generally well-tolerated, it can clog pores in people prone to breakouts, so it's best for dry or normal skin types.

Quick decision guide

Useful, but context matters

PEG-6 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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging PEG-6 Lanolate.
  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

PEG-6 Lanolate is a semi-synthetic ingredient created by reacting lanolin with ethylene oxide (PEG-6). This process makes the natural lanolin more water-soluble and less sticky, while retaining its moisturizing properties. It appears as a waxy solid or paste and is used to improve texture and stability in cosmetic products.

How it works

In a cosmetic product, PEG-6 Lanolate works in two main ways. First, as an emollient, it sits on the skin's surface to fill in gaps between skin cells, making the skin feel smoother and softer. Second, as an emulsifier, it helps blend oil and water ingredients together so the product stays uniform and doesn't separate. It also helps other ingredients spread more easily on the skin.

Pros

Effective emollient

Provides noticeable skin softening and smoothing without a heavy, greasy feel, making it suitable for daily moisturizers.

Stabilizes formulas

Acts as a reliable emulsifier to keep oil and water mixed, improving product consistency and shelf life.

Cons and cautions

Moderate comedogenic risk

Rated around 3-4 on the comedogenic scale, meaning it can clog pores and trigger breakouts in acne-prone individuals.

Not vegan-friendly

Derived from lanolin (sheep's wool oil), so it is not suitable for those following a vegan lifestyle or avoiding animal products.

Best for

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

Use caution if

  • Individuals with acne-prone or oily skin
  • Vegans or those avoiding animal-derived ingredients
  • Anyone with a known lanolin allergy

Usage tips

Use in moisturizers or cleansers for dry skin, but avoid if you have a history of breakouts.
Patch test before first use if you have sensitive skin or a known lanolin sensitivity.
Combine with non-comedogenic ingredients if formulating for combination skin.

Safety summary

PEG-6 Lanolate is generally safe for most people when used in cosmetics. The main concerns are its moderate comedogenic potential and possible allergic reactions in those sensitive to lanolin. Regulatory bodies like the CIR have reviewed it and found it safe at typical concentrations.

Research notes

Research on PEG-6 Lanolate is limited, but it is considered a well-established ingredient with a history of safe use. Studies on lanolin derivatives indicate low irritation potential, though comedogenicity varies by individual. The CIR panel's safety assessment supports its use in cosmetics.

Common label clues

Typical concentration
0.5% to 5%
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, Bar soaps, Hair conditioners
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-6 Lanolate is considered safe by the Cosmetic Ingredient Review (CIR) panel at typical use concentrations.
  • The 'PEG-6' indicates the number of ethylene oxide units added, which affects water solubility and mildness.
