Ingredient review
PEG-7 Lanolate
INCI: PEG-7 Lanolate
A gentle, water-soluble lanolin derivative that softens skin and helps cleanse without stripping, but may clog pores for some.
In plain English
PEG-7 Lanolate is a modified version of lanolin (a natural oil from sheep's wool) that has been treated to become water-soluble. This means it can mix with water easily, making it useful in cleansers and moisturizers. It helps soften and smooth the skin while also helping other ingredients spread evenly. Because it is derived from lanolin, it may still have a moderate chance of clogging pores, so it's not ideal for very oily or acne-prone skin.

Quick decision guide
Useful, but context matters
PEG-7 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.
- Step 1Start with the score, then check the irritation and clogging risk before judging PEG-7 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
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 created by reacting lanolin with ethylene oxide (PEG) to make it water-soluble. It retains the moisturizing properties of lanolin but is easier to rinse off.
How it works
It works as an emollient by filling in the gaps between skin cells to smooth and soften the skin. As a surfactant, it helps water mix with oil and dirt, allowing them to be rinsed away during cleansing.
Pros
Water-soluble emollient
Unlike traditional lanolin, PEG-7 Lanolate rinses off easily, making it suitable for cleansers and conditioners without leaving a greasy residue.
Gentle cleansing
It helps remove dirt and oil without stripping the skin's natural moisture barrier, which is beneficial for dry or sensitive skin.
Cons and cautions
Moderate comedogenic risk
Because it is derived from lanolin, it may clog pores for some people, especially those with acne-prone or oily skin.
Animal-derived source
It 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 gentle cleansing
- Those who want a moisturizing cleanser or conditioner
Use caution if
- Individuals with known lanolin allergy
- Acne-prone or oily skin types concerned about clogged pores
Usage tips
Safety summary
Generally considered safe for most people when used in rinse-off products. The main concerns are potential for clogged pores and allergic reactions in those sensitive to lanolin.
Research notes
Limited direct studies on PEG-7 Lanolate, but lanolin derivatives are well-studied as safe emollients. 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 by the FDA and EU CosIng database. No known restrictions at typical concentrations.
- Common uses
- Cleansers, Moisturizers, Hair conditioners, Body washes
- Environmental note
- Lanolin is a byproduct of wool production, making it a renewable resource. However, the PEG processing involves synthetic chemistry and may have environmental considerations.
Good to know
- PEG-7 Lanolate is often used in 'gentle' or 'moisturizing' cleansers.
- The 'PEG-7' indicates the number of ethylene oxide units, which affects water solubility.
