Ingredient review
PEG-2 Hydrogenated Tallow Amine
INCI: PEG-2 Hydrogenated Tallow Amine
A synthetic emulsifier that helps mix oil and water, but may be mildly irritating for sensitive skin and has moderate comedogenic potential.
In plain English
PEG-2 Hydrogenated Tallow Amine is a man-made ingredient that helps oil and water blend together in products like conditioners and cleansers. It is made from hydrogenated tallow (a processed animal fat) combined with ethylene oxide. While effective at creating smooth textures, it can be a bit harsh for very sensitive skin and may clog pores for some people.

Quick decision guide
Useful, but context matters
PEG-2 Hydrogenated 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-2 Hydrogenated 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 synthetic surfactant and emulsifier created by reacting hydrogenated tallow (a processed animal fat) with ethylene oxide. It belongs to the PEG (polyethylene glycol) family of compounds.
How it works
It reduces surface tension between oil and water, allowing them to mix into a stable emulsion. In hair products, it also acts as an antistatic agent, reducing flyaways by coating the hair shaft with a thin film.
Pros
Effective emulsifier
Helps oil and water blend smoothly, giving products a consistent, non-separating texture.
Reduces static
In hair products, it coats the hair to minimize flyaways and improve manageability.
Cons and cautions
Potential irritation
May cause stinging or redness for those with sensitive or compromised skin, especially in leave-on formulas.
Moderate comedogenic risk
Rated as moderately likely to clog pores, so acne-prone individuals may want to patch test first.
Best for
- People with normal to oily hair looking for anti-static benefits
- Those using rinse-off products like shampoos or body washes who want a stable formula
Use caution if
- Individuals with very sensitive or acne-prone skin
- Those seeking vegan or plant-based ingredients
Usage tips
Safety summary
Generally safe for most people when used in rinse-off products at typical concentrations. However, it has moderate irritation and comedogenic potential, so sensitive or acne-prone skin should approach with caution. Avoid leave-on products if you have reactive skin.
Research notes
The Cosmetic Ingredient Review (CIR) panel has evaluated PEG compounds and found them safe for cosmetic use when formulated to minimize impurities. Studies on tallow amine derivatives show low acute toxicity but potential for mild skin irritation at higher concentrations.
Common label clues
- Typical concentration
- Typically 0.5–5% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) within concentration limits. The Cosmetic Ingredient Review (CIR) panel has reviewed PEG compounds and considers them safe when formulated properly.
- Common uses
- Hair conditioners, Cleansers, Emulsions
- Environmental note
- Derived from animal fat (tallow), which is a byproduct of the meat industry. Not biodegradable in all aquatic environments; check product labels for eco-certifications.
Good to know
- PEG compounds can sometimes contain trace impurities like 1,4-dioxane, though reputable manufacturers purify them to safe levels.
- Hydrogenated tallow is a processed animal fat, so this ingredient is not vegan.
