PEG-7 Tallow Amine

INCI: PEG-7 Tallow Amine

PEG-7 Tallow Amine is an effective emulsifier but may be moderately irritating and comedogenic, and its animal-derived origin raises concerns for some users.

In plain English

PEG-7 Tallow Amine is a helper ingredient that allows oil and water to mix in products like cleansers and shampoos. It's made from animal fat (tallow) that has been processed with ethylene oxide to make it water-friendly. While it works well, it can be a bit harsh for sensitive skin and may clog pores for some people. Because it comes from animals, it's not suitable for vegans or those avoiding animal-derived ingredients.

Quick decision guide

Useful, but context matters

PEG-7 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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging PEG-7 Tallow Amine.
  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

moderate

Can bother some users, especially with frequent use, damaged skin, or strong companion ingredients.

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

A semi-synthetic surfactant and emulsifier created by reacting tallow (rendered animal fat) with ethylene oxide. The 'PEG-7' indicates the average number of ethylene oxide units attached, which determines its water solubility and mildness.

How it works

It reduces the surface tension between oil and water, allowing them to blend into a stable emulsion. In cleansers, it helps lift dirt and oil from the skin so they can be rinsed away. Its ethoxylated structure also gives it some conditioning properties, making hair feel softer after shampooing.

Pros

Strong emulsifier

Effectively blends oil and water, creating stable, uniform products that feel smooth and perform consistently.

Mild conditioning

Leaves hair and skin feeling softer compared to harsher surfactants, making it useful in shampoos and body washes.

Cons and cautions

Moderate irritation potential

Can cause stinging, redness, or dryness for sensitive skin, especially in leave-on products or high concentrations.

Not vegan or cruelty-free friendly

Derived from animal fat (tallow), which may conflict with ethical preferences and is not suitable for vegan routines.

Best for

  • Those with normal to oily skin looking for effective cleansing
  • People who don't mind animal-derived ingredients in their products

Use caution if

  • Vegans and those avoiding animal-derived ingredients
  • Individuals with sensitive or easily irritated skin
  • Acne-prone skin types (may clog pores)

Usage tips

Best used in rinse-off products like shampoos and body washes to minimize skin contact time.
If you have sensitive skin, look for products where PEG-7 Tallow Amine appears low on the ingredient list.
Pair with soothing ingredients like aloe or panthenol to reduce potential irritation.

Safety summary

PEG-7 Tallow Amine is considered safe in rinse-off products at typical use levels, but it can be moderately irritating and comedogenic. The ethoxylation process may produce trace 1,4-dioxane, a potential carcinogen, though levels are tightly controlled in quality manufacturing. Sensitive and acne-prone skin should use caution.

Research notes

Studies on PEG amines indicate low acute toxicity and moderate skin irritation potential. The Cosmetic Ingredient Review (CIR) has reviewed related PEG tallow amines and concluded they are safe in rinse-off products when formulated properly. No recent high-quality human studies specifically on PEG-7 Tallow Amine were found.

Common label clues

Typical concentration
Usually 0.5–5% in rinse-off products; lower in leave-on formulas
Regulatory status
Approved for use in cosmetics in the EU, US, and many other regions, with concentration limits typically set by the manufacturer's safety assessment. The Cosmetic Ingredient Review (CIR) has evaluated related PEG amines and found them safe as used.
Common uses
Cleansers, Shampoos, Conditioners, Emulsions
Environmental note
Tallow is a byproduct of the meat industry, which may raise sustainability concerns. The ethoxylation process also requires energy and chemical processing. Biodegradability is moderate.

Good to know

  • PEG-7 Tallow Amine is sometimes listed simply as 'PEG-7 Tallow Amine' on labels — no common synonyms.
  • The 'PEG' part means it has been processed with ethylene oxide; trace amounts of 1,4-dioxane can form during manufacturing, though reputable brands purify to remove it.
