Ingredient review
PEG-30 Tallow Amine
INCI: PEG-30 Tallow Amine
An effective emulsifier and surfactant, but may cause irritation for sensitive skin and raises ethical concerns due to animal-derived tallow.
In plain English
PEG-30 Tallow Amine is a helper ingredient that allows oil and water to mix in products like shampoos and cleansers. It's made from tallow (rendered animal fat) processed with ethylene oxide. While it works well, it can be drying or irritating for some people, especially those with sensitive skin. It also raises ethical questions for vegans or those avoiding animal-derived ingredients.

Quick decision guide
Useful, but context matters
PEG-30 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-30 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
A semi-synthetic surfactant and emulsifier created by reacting tallow (animal fat) with ethylene oxide. The 'PEG-30' part indicates the number of ethylene oxide units, which helps make the ingredient water-soluble.
How it works
It reduces the surface tension between oil and water, allowing them to mix into a stable emulsion. In cleansers, it helps lift dirt and oil from the skin and hair so they can be rinsed away.
Pros
Strong emulsifier
Effectively blends oil and water, ensuring product stability and consistent texture.
Good lather
Creates a rich foam in shampoos and body washes, which many users associate with effective cleansing.
Cons and cautions
Potential irritant
Can cause stinging, dryness, or redness for sensitive skin types, especially with frequent use.
Animal-derived source
Made from tallow, which is not suitable for vegans and may raise ethical concerns about animal byproducts.
Best for
- People with normal to oily skin looking for effective cleansing
- Those not concerned about animal-derived ingredients
Use caution if
- Individuals with sensitive, reactive, or eczema-prone skin
- Vegans or those avoiding animal-derived ingredients
Usage tips
Safety summary
Generally considered safe in rinse-off products at low concentrations, but may cause irritation for sensitive individuals. The main concerns are skin sensitivity and the presence of potential processing contaminants like 1,4-dioxane.
Research notes
Limited peer-reviewed studies specifically on PEG-30 Tallow Amine. Safety assessments rely on general knowledge of PEG compounds and tallow derivatives. The Cosmetic Ingredient Review (CIR) has evaluated similar PEG alkyl amines and found them safe in rinse-off products at low concentrations.
Common label clues
- Typical concentration
- Low (usually under 5%)
- Regulatory status
- Approved for use in cosmetics in the US and EU, with concentration limits in some rinse-off products. The EU CosIng database lists it as a surfactant and emulsifier.
- Common uses
- Cleansers, Shampoos, Conditioners, Hair dyes
- Environmental note
- Tallow is a byproduct of animal agriculture, which has a significant environmental footprint. The PEG processing also involves fossil fuel-derived ethylene oxide.
Good to know
- PEG compounds can sometimes contain trace amounts of 1,4-dioxane, a potential carcinogen, though reputable manufacturers purify their ingredients.
- Tallow is a byproduct of the meat industry, so this ingredient is not vegan.
