Ingredient review
Hydrogenated Tallowoyl Glutamic Acid
INCI: Hydrogenated Tallowoyl Glutamic Acid
A mild, soap-like cleanser that effectively removes dirt and oil without stripping the skin, making it a good choice for sensitive or dry skin types.
In plain English
This ingredient is a gentle cleansing agent made from animal fat (tallow) and an amino acid (glutamic acid). It works like a mild soap to lift away dirt, oil, and makeup from your skin, but it's much less drying than traditional soaps. Because it's so gentle, it's often used in cleansers for sensitive or dry skin.

Quick decision guide
Useful, but context matters
Hydrogenated Tallowoyl Glutamic Acid 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 Hydrogenated Tallowoyl Glutamic Acid.
- 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 semi-synthetic surfactant created by combining hydrogenated tallow (a processed animal fat) with glutamic acid (an amino acid). It belongs to the acyl glutamic acid family of mild cleansing agents.
How it works
It has both water-loving and oil-loving parts, so it can surround and lift away oil-based impurities (like sebum and makeup) from the skin's surface, allowing them to be rinsed away with water. Its large molecular structure makes it less penetrating and therefore less irritating than harsher surfactants like sodium lauryl sulfate.
Pros
Very gentle on skin
Its large molecular structure means it doesn't penetrate deeply, so it cleans without causing irritation or stripping the skin's natural moisture barrier.
Good for dry and sensitive skin
Unlike many traditional soaps, this ingredient leaves skin feeling soft and hydrated after washing, making it ideal for those prone to dryness or irritation.
Cons and cautions
Not vegan-friendly
Because it's derived from animal fat (tallow), it's not suitable for anyone following a vegan lifestyle or avoiding animal products.
May not foam as much
It produces a low, creamy lather rather than big bubbles, which some people associate with a less effective clean, though it still works well.
Best for
- People with dry or sensitive skin looking for a non-stripping cleanser
- Those who prefer mild, amino-acid-based cleansers
Use caution if
- Vegans or those avoiding animal-derived ingredients
- Individuals with very oily skin who prefer a more foaming, deep-cleansing surfactant
Usage tips
Safety summary
Considered safe for use in cosmetics at typical concentrations. It has a low irritation and comedogenic risk, making it suitable for sensitive skin. The main concern is its animal origin, not its safety profile.
Research notes
Acyl glutamates, including tallowoyl glutamic acid, are well-documented as mild surfactants with excellent skin compatibility. Studies show they cause less protein denaturation and skin barrier disruption compared to harsher sulfates.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and most major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Facial cleansers, Makeup removers, Bar soaps, Shampoos
- Environmental note
- Tallow is a byproduct of the meat industry, so using it can be seen as using a waste product. However, it is not suitable for vegans. The ingredient is biodegradable.
Good to know
- Hydrogenated tallow is a processed form of tallow that is more stable and less likely to go rancid.
- This ingredient is often listed near the top of ingredient lists in mild cleansers because it's a primary cleansing agent.
