TEA-Carbomer
INCI: TEA-Carbomer
A safe, effective thickener that gives your skincare products a pleasant gel or cream texture without clogging pores.
In plain English
TEA-Carbomer is a synthetic ingredient that helps turn watery liquids into thicker gels or creams. It's like a thickening agent that gives your moisturizer or serum that smooth, non-runny feel. It also helps keep the ingredients mixed together so they don't separate. It's very common in clear gels and is generally considered gentle on skin.

Quick decision guide
Useful, but context matters
TEA-Carbomer 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-Carbomer.
- 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
strongThere is a stronger practical or research basis for the ingredient role described here.
What it is
TEA-Carbomer is a salt formed by reacting Carbomer (a high-molecular-weight polymer of acrylic acid) with triethanolamine (TEA). This neutralization process creates a clear, viscous gel that is widely used in cosmetics as a thickener and stabilizer.
How it works
When added to water, Carbomer particles swell and form a loose network. Adding TEA neutralizes the Carbomer, causing the polymer chains to uncoil and expand, which dramatically increases the viscosity of the solution. This creates a smooth, stable gel or cream texture that also helps suspend other ingredients like oils and active particles.
Pros
Excellent texture enhancer
Creates a smooth, non-greasy gel or cream that spreads easily and feels light on the skin, making it ideal for serums and gel moisturizers.
Stabilizes formulas
Helps keep oil and water mixed together, preventing your product from separating and ensuring you get a consistent dose of ingredients every time.
Cons and cautions
Can feel tacky at high levels
If used in too high a concentration, the product may feel sticky or tacky on the skin, which can be uncomfortable, especially under makeup.
Synthetic origin
It is a man-made ingredient, which may not appeal to those seeking a fully natural or organic skincare routine.
Best for
- Anyone who prefers lightweight, non-greasy gel textures
- People with oily or combination skin looking for a matte finish
Use caution if
- Those with known sensitivity to triethanolamine (rare)
- Individuals who prefer only natural thickeners
Usage tips
Safety summary
TEA-Carbomer is considered safe for use in cosmetics at typical concentrations. It has a low irritation and comedogenic risk. Rare cases of sensitivity are usually due to the triethanolamine component, but overall it is well-tolerated by most skin types.
Research notes
The safety of Carbomer and its salts has been reviewed by the Cosmetic Ingredient Review (CIR) panel, which concluded they are safe for use in cosmetics. Studies show they are non-irritating and non-sensitizing at typical use levels.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Approved for use in cosmetics by the FDA and the European Commission. The Cosmetic Ingredient Review (CIR) panel has deemed Carbomer and TEA-Carbomer safe as used in cosmetics.
- Common uses
- Gels, Creams, Serums, Lotions, Sunscreens
- Environmental note
- TEA-Carbomer is synthetic and not biodegradable. However, it is used in very small amounts in products, so its environmental impact is considered low.
Good to know
- TEA-Carbomer is often used in clear gel formulas because it creates a transparent gel.
- It is considered non-comedogenic, meaning it is unlikely to clog pores.
- The 'TEA' part is triethanolamine, a pH adjuster that activates the Carbomer.
