Ingredient review
Talloweth-7
INCI: TALLOWETH-7
Talloweth-7 is a functional but controversial emulsifier — effective at blending ingredients but derived from animal fat and may cause irritation for sensitive skin.
In plain English
Talloweth-7 is a man-made ingredient that helps oil and water mix together in products like cleansers and shampoos. It is made from animal fat (tallow) that has been chemically modified with ethylene oxide. While it works well as a cleanser and emulsifier, it can be drying or irritating for some people, especially those with sensitive or reactive skin.

Quick decision guide
Useful, but context matters
Talloweth-7 can be useful, but watch for some irritation potential.
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 Talloweth-7.
- 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
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
Talloweth-7 is an ethoxylated fatty alcohol derived from beef tallow. It belongs to the PEG (polyethylene glycol) ether family and is used as a non-ionic surfactant and emulsifier in personal care products.
How it works
Talloweth-7 reduces the surface tension between oil and water, allowing them to form a stable mixture (emulsion). In cleansers, it helps lift dirt, sebum, and makeup from the skin so they can be rinsed away with water.
Pros
Strong emulsifier
Effectively blends oil and water, creating stable, creamy formulas that rinse cleanly without heavy residue.
Good cleansing power
Helps remove excess oil, dirt, and makeup, making it useful in shampoos and body washes for oily skin or hair.
Cons and cautions
Animal-derived
Made from beef tallow, so it is not suitable for vegans or those seeking plant-based or cruelty-free products.
Potential irritation
Can be drying or irritating for sensitive or compromised skin, especially with frequent use in leave-on products.
Best for
- People with normal to oily skin looking for effective cleansing
- Those who don't mind animal-derived ingredients in their routine
Use caution if
- Vegans and vegetarians
- People with sensitive, dry, or eczema-prone skin
- Anyone avoiding PEG compounds or potential 1,4-dioxane contamination
Usage tips
Safety summary
Talloweth-7 is generally considered safe for use in rinse-off cosmetics at typical concentrations. The main safety concerns are potential skin irritation for sensitive individuals and the presence of trace 1,4-dioxane, a byproduct of ethoxylation. Regulatory bodies set limits on 1,4-dioxane in finished products.
Research notes
Research on Talloweth-7 is limited, but it is similar to other ethoxylated alcohols. Studies indicate that PEG compounds can be mild to moderate irritants depending on concentration and chain length. The Cosmetic Ingredient Review (CIR) has evaluated related PEG ethers and found them safe when formulated to minimize impurities.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) with no specific concentration restrictions, though manufacturers are encouraged to minimize 1,4-dioxane contamination.
- Common uses
- Cleansers, Shampoos, Body washes, Bar soaps, Emulsions
- Environmental note
- Derived from animal agriculture byproducts; not biodegradable in all conditions. Ethoxylation process has environmental concerns related to energy use and potential byproducts.
Good to know
- Talloweth-7 is often used in bar soaps and traditional cleansing bars for its ability to create a rich lather.
- The '7' in the name refers to the average number of ethylene oxide units added, which affects its water solubility and mildness.
