Ingredient review
PEG-11 Tallow Amine
INCI: PEG-11 Tallow Amine
PEG-11 Tallow Amine is an effective emulsifier but may cause irritation for sensitive skin and raises ethical concerns due to its animal-derived origin.
In plain English
PEG-11 Tallow Amine is a man-made ingredient that helps oil and water mix together in products like shampoos and cleansers. It is made from tallow (rendered animal fat) combined with a petrochemical called ethylene oxide. While it works well, it can be drying or irritating for some people, especially those with sensitive skin. Because it comes from animals, it is not suitable for vegans or those avoiding animal-derived ingredients.

Quick decision guide
Read the cautions before using
PEG-11 Tallow Amine can be useful, but watch for some irritation potential and 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-11 Tallow Amine.
- 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
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
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
PEG-11 Tallow Amine is a semi-synthetic surfactant and emulsifier. It is created by reacting tallow (a fat from cows or sheep) with ethylene oxide, producing a molecule that can reduce surface tension and help blend oil and water phases in a formula.
How it works
In a cosmetic product, PEG-11 Tallow Amine acts as an emulsifier, allowing water and oil ingredients to stay mixed together. It also has surfactant properties, meaning it can help lift dirt and oil from the skin or hair so they can be rinsed away. This makes it useful in cleansers and shampoos.
Pros
Strong emulsifier
Effectively blends oil and water, helping to create stable, uniform products like creams and cleansers.
Good cleansing power
Its surfactant properties help lift and remove excess oil, dirt, and buildup from skin and hair.
Cons and cautions
Potential irritation
Can cause dryness, redness, or stinging for those with sensitive or compromised skin, especially in leave-on products.
Animal-derived
Made from tallow, so it is not vegan-friendly and may be a concern for those seeking plant-based or ethical ingredients.
Best for
- People with normal to oily skin or hair who use rinse-off products
- Those looking for a cost-effective emulsifier in commercial formulas
Use caution if
- Individuals with sensitive, reactive, or eczema-prone skin
- Vegans or those avoiding animal-derived ingredients
Usage tips
Safety summary
PEG-11 Tallow Amine is considered safe for use in rinse-off cosmetics at typical concentrations. However, it can cause skin irritation in sensitive individuals, and its animal origin may be a concern for ethical or religious reasons. The manufacturing process may also produce trace levels of 1,4-dioxane, a potential contaminant, though reputable brands test for purity.
Research notes
Research on PEG-11 Tallow Amine is limited, but studies on similar PEGylated amines indicate moderate skin irritation potential. The Cosmetic Ingredient Review (CIR) panel has reviewed related ingredients and found them safe for rinse-off use with proper formulation. No long-term human studies are available.
Common label clues
- Typical concentration
- Typically 0.5–5% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the US and EU with no specific concentration restrictions, but formulators are encouraged to minimize irritation potential.
- Common uses
- Cleansers, Shampoos, Conditioners, Hair dyes
- Environmental note
- Derived from animal agriculture byproducts, which may have a lower environmental footprint than some synthetic alternatives, but raises ethical concerns for some consumers.
Good to know
- The 'PEG-11' indicates the number of ethylene oxide units, which affects the ingredient's water solubility and mildness.
- Tallow-derived ingredients are sometimes listed under generic names, so vegans should look for certified vegan labels.
- This ingredient is more common in professional or salon hair products than in everyday skincare.
