Ingredient review
Disodium Tallowamphodiacetate
INCI: Disodium Tallowamphodiacetate
A gentle, animal-derived surfactant that cleans effectively but may not suit those avoiding animal ingredients.
In plain English
Disodium Tallowamphodiacetate is a mild cleansing ingredient made from beef tallow (rendered animal fat). It helps create a gentle foam that lifts dirt and oil from the skin without causing dryness or irritation. Because it is amphoteric (it can act as both an acid and a base), it works well with other cleansing ingredients to make formulas milder on the skin. It is commonly found in soaps, shampoos, and body washes that claim to be gentle or for sensitive skin.

Quick decision guide
Useful, but context matters
Disodium Tallowamphodiacetate is generally a lower-concern ingredient when the full formula suits your skin.
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 Disodium Tallowamphodiacetate.
- 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
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
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
A surfactant (cleansing agent) produced by chemically modifying fatty acids from beef tallow. It belongs to the amphoteric class of surfactants, meaning it can adjust its charge depending on the pH of the product, which helps reduce irritation.
How it works
In a cosmetic product, it lowers the surface tension between water and oil, allowing the product to trap dirt and sebum so they can be rinsed away. Its amphoteric nature also helps it boost foam and stabilize formulas while being less harsh on the skin barrier than many other surfactants.
Pros
Very gentle on skin
Its amphoteric nature makes it one of the mildest surfactants, ideal for sensitive or dry skin types that react to stronger cleansers.
Good foam booster
It helps create a creamy, stable lather that feels luxurious and spreads easily, improving the overall user experience.
Cons and cautions
Animal-derived ingredient
Since it comes from beef tallow, it is not suitable for vegans, vegetarians, or those who prefer to avoid animal byproducts in their skincare.
Limited cleansing power alone
On its own, it may not thoroughly remove heavy makeup or waterproof sunscreen, so it is often paired with stronger surfactants.
Best for
- People with dry or sensitive skin looking for a mild cleanser
- Those who prefer traditional soap-based cleansing bars
Use caution if
- Vegans and vegetarians
- Anyone seeking a fully plant-based or synthetic cleansing routine
Usage tips
Safety summary
Disodium Tallowamphodiacetate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for sensitive skin. The main concern is its animal origin, not safety.
Research notes
Research on this specific ingredient is limited, but it belongs to a well-studied class of amphoteric surfactants known for mildness. Safety assessments by the Cosmetic Ingredient Review (CIR) have found similar tallow-derived surfactants safe in rinse-off products.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics by the FDA and EU CosIng database. No known restrictions at typical concentrations.
- Common uses
- Facial cleansers, Body washes, Shampoos, Bar soaps
- Environmental note
- Derived from a byproduct of the meat industry, which may be considered more sustainable than using virgin plant oils, but still involves animal agriculture.
Good to know
- Disodium Tallowamphodiacetate is often listed alongside other amphoteric surfactants in 'sulfate-free' formulas.
- It is biodegradable and considered safe for the environment at typical use levels.
