Ingredient review
TEA-Cocoyl Glutamate
INCI: TEA-Cocoyl Glutamate
A gentle, plant-derived surfactant that cleanses without stripping the skin barrier, ideal for sensitive or dry skin.
In plain English
TEA-Cocoyl Glutamate is a mild cleansing ingredient made from coconut oil and an amino acid (glutamic acid). It helps remove dirt, oil, and makeup without leaving your skin feeling tight or dry. Unlike harsher sulfates, it respects your skin’s natural moisture barrier, making it a popular choice for gentle, everyday cleansers.

Quick decision guide
Easy yes for most routines
TEA-Cocoyl 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 TEA-Cocoyl 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
TEA-Cocoyl 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 sulfate-based cleansers. It is created by reacting fatty acids from coconut oil with glutamic acid (an amino acid) and then neutralizing with triethanolamine (TEA).
How it works
In a cleanser, TEA-Cocoyl Glutamate reduces the surface tension of water, allowing it to penetrate oils and lift away impurities. Its molecular structure has a water-loving head and an oil-loving tail, which forms tiny micelles that trap dirt and oil. Because it is derived from an amino acid, it has a pH close to that of healthy skin (around 5.5), so it cleanses without disrupting the skin’s acid mantle.
Pros
Ultra-gentle cleansing
Unlike sodium lauryl sulfate, TEA-Cocoyl Glutamate cleanses without stripping the skin’s natural oils, making it ideal for daily use on sensitive or dry skin.
Skin-friendly pH
Its pH is naturally close to that of healthy skin (around 5.5), which helps maintain the acid mantle and reduces the risk of irritation or disruption of the skin barrier.
Cons and cautions
Low foam production
This surfactant creates a creamy, low-lather experience rather than big bubbles. If you enjoy a rich, foamy wash, you may find it less satisfying at first.
Higher cost
Amino-acid surfactants are more expensive to produce than conventional sulfates, so products containing them often come with a higher price tag.
Best for
- People with dry, sensitive, or reactive skin who need a non-stripping cleanser
- Anyone looking to switch to a sulfate-free, gentler cleansing routine
Use caution if
- Those who prefer high-foam, bubbly cleansers (this ingredient produces a creamy, low lather)
Usage tips
Safety summary
TEA-Cocoyl Glutamate is considered safe for use in cosmetics at typical concentrations. It is non-irritating and non-sensitizing for the vast majority of users. The triethanolamine component is regulated to minimize potential nitrosamine contamination, but levels in finished products are well within safety limits.
Research notes
Amino-acid surfactants like TEA-Cocoyl Glutamate have been studied for their mildness and skin compatibility. Research shows they cause significantly less protein denaturation and skin barrier disruption compared to sodium lauryl sulfate. However, most evidence comes from in vitro or patch-test studies rather than large-scale human trials.
Common label clues
- Typical concentration
- 5–20% in rinse-off cleansers; lower in leave-on products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and most major markets. The triethanolamine component is restricted in some regions to a maximum concentration of 5% in rinse-off products to limit nitrosamine formation.
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby care products
- Environmental note
- Derived from coconut oil and fermented glutamic acid, this surfactant is biodegradable and generally considered more environmentally friendly than petroleum-based sulfates.
Good to know
- TEA-Cocoyl Glutamate is considered biodegradable and is often used in eco-friendly formulations.
- It is frequently paired with other mild surfactants like cocamidopropyl betaine to adjust foam and viscosity.
