Ingredient review
Sodium Cocoyl/Hydrogenated Tallow Glutamate
INCI: SODIUM COCOYL/HYDROGENATED TALLOW GLUTAMATE
A gentle, amino-acid-based surfactant that cleanses effectively while being kind to sensitive skin.
In plain English
This ingredient is a mild cleansing agent made from coconut oil and animal fat (tallow) combined with glutamic acid, an amino acid. It helps remove dirt and oil from your skin without stripping away its natural moisture barrier, making it a popular choice for gentle cleansers and sensitive-skin formulas.

Quick decision guide
Easy yes for most routines
Sodium Cocoyl/Hydrogenated Tallow Glutamate 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 Sodium Cocoyl/Hydrogenated Tallow Glutamate.
- 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
Sodium Cocoyl/Hydrogenated Tallow Glutamate is a surfactant, meaning it helps water mix with oil and dirt so they can be rinsed away. It belongs to the family of amino-acid surfactants, which are known for being much milder than traditional sulfates like sodium lauryl sulfate.
How it works
When you wash your face, this ingredient reduces the surface tension of water, allowing it to penetrate and lift away sebum, makeup, and impurities. Its large molecular structure means it doesn't penetrate deeply into the skin, so it cleans without disrupting the skin barrier or causing tightness.
Pros
Extremely gentle on skin
Unlike sulfates that can strip the skin barrier, this amino-acid surfactant cleans without causing tightness or irritation, making it ideal for daily use on sensitive or reactive skin.
Environmentally friendlier
It is biodegradable and derived from renewable sources (coconut oil and tallow), with a lower environmental impact compared to many petroleum-based surfactants.
Cons and cautions
Animal-derived component
The hydrogenated tallow comes from beef fat, so this ingredient is not vegan or suitable for those avoiding animal products. Always check the label if this matters to you.
Less foaming lather
It produces a creamy, low-foam lather rather than big bubbles. If you enjoy a rich, foamy wash, you might find this less satisfying, though it still cleans effectively.
Best for
- People with dry, sensitive, or eczema-prone skin who need a gentle cleanser
- Anyone looking to switch from harsh sulfate cleansers to a milder option
Use caution if
- Strict vegans or those avoiding animal-derived ingredients (tallow is from beef fat)
Usage tips
Safety summary
Considered safe for cosmetic use at typical concentrations. Low irritation and comedogenic risk. The main concern is ethical (animal-derived) rather than safety-related. No known toxicity or sensitization issues in published research.
Research notes
Amino-acid surfactants like this one are well-studied for mildness and skin compatibility. Research shows they cause less barrier disruption and lower irritation compared to sodium lauryl sulfate. However, specific studies on this exact blend are limited; most evidence comes from related glutamates.
Common label clues
- Typical concentration
- 1–15% in rinse-off products; lower in leave-on formulations
- Regulatory status
- Approved for use in cosmetics worldwide, including by the FDA (US) and EU CosIng database, with no known restrictions at typical concentrations.
- Common uses
- Facial cleansers, Body washes, Shampoos, Makeup removers
- Environmental note
- Biodegradable and derived from natural fats, but the tallow component raises ethical concerns for some consumers. Coconut oil sourcing can also have environmental impacts if not sustainably farmed.
Good to know
- This ingredient is often listed near the top of cleanser ingredient lists because it's a primary cleansing agent.
- It is pH-balanced and typically works well in formulations with a pH around 5.5, which is close to skin's natural pH.
- The 'cocoyl' part comes from coconut oil, and 'tallow' from beef fat—both are fatty sources that make the surfactant mild.
