TEA-Lauraminopropionate
INCI: TEA-Lauraminopropionate
A gentle surfactant that effectively cleanses without stripping the skin, suitable for sensitive skin types.
In plain English
TEA-Lauraminopropionate is a mild cleansing ingredient often found in soaps and shampoos. It helps water mix with oil and dirt so they can be rinsed away, but it's much gentler than traditional harsh detergents like sodium lauryl sulfate. Think of it as a friendly cleaner that gets the job done without leaving your skin feeling tight or dry.

Quick decision guide
Useful, but context matters
TEA-Lauraminopropionate 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-Lauraminopropionate.
- 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-Lauraminopropionate is a synthetic surfactant derived from lauric acid (a fatty acid from coconut or palm oil) and triethanolamine. It belongs to the class of amphoteric surfactants, meaning it can work in both acidic and alkaline conditions, making it versatile and mild.
How it works
In a cosmetic product, this ingredient reduces the surface tension between water and oil, allowing impurities to be lifted from the skin and rinsed away. Its amphoteric nature means it is less likely to disrupt the skin's natural barrier compared to harsher anionic surfactants, resulting in a gentler cleansing experience.
Pros
Mild on skin
This surfactant is known for its low irritation potential, making it a good choice for sensitive skin types who react to harsher cleansers.
Effective cleanser
It efficiently removes dirt, oil, and makeup without stripping the skin's natural moisture barrier, leaving skin feeling comfortable.
Cons and cautions
Synthetic origin
As a lab-created ingredient, it may not appeal to consumers seeking 100% natural or plant-derived formulations.
Potential for slight dryness
In high concentrations or without balancing co-surfactants, it can still cause mild dryness, especially for very dry or compromised skin.
Best for
- People with sensitive or dry skin
- Those looking for a mild, everyday cleanser
Use caution if
- Individuals strictly avoiding synthetic ingredients
- Those with known triethanolamine allergy (rare)
Usage tips
Safety summary
TEA-Lauraminopropionate is considered safe for use in cosmetics at typical concentrations. It has low irritation and sensitization potential, though individuals with very sensitive skin or allergies to triethanolamine should patch test first.
Research notes
Studies indicate that amphoteric surfactants like TEA-Lauraminopropionate are significantly milder than anionic surfactants such as SLS. However, most evidence comes from industry testing and general surfactant safety data rather than large-scale independent clinical trials.
Common label clues
- Typical concentration
- 1–10% in rinse-off formulas
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Facial cleansers, Body washes, Shampoos
- Environmental note
- Synthetic but biodegradable; sourcing of lauric acid may involve palm oil, so look for sustainably sourced versions if environmental impact is a concern.
Good to know
- Often used alongside other mild surfactants to create a balanced, gentle cleansing system.
- It is considered biodegradable and is commonly used in 'sulfate-free' formulations.
