Ingredient review
TEA-Lauryl Phosphate
INCI: TEA-Lauryl Phosphate
A gentle, phosphate-based surfactant that effectively cleanses without over-drying, suitable for sensitive skin types.
In plain English
TEA-Lauryl Phosphate is a synthetic cleansing ingredient that helps water mix with oil and dirt so they can be rinsed away. It's considered milder than traditional sulfates like sodium lauryl sulfate, making it a popular choice for gentle cleansers and shampoos. Think of it as a hard-working but polite cleaner that gets the job done without leaving your skin feeling tight or stripped.

Quick decision guide
Useful, but context matters
TEA-Lauryl Phosphate 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-Lauryl Phosphate.
- 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-Lauryl Phosphate is an anionic surfactant derived from lauryl alcohol (a fatty alcohol from coconut or palm oil) and phosphoric acid, neutralized with triethanolamine. It belongs to the alkyl phosphate family, known for their mild cleansing properties.
How it works
As a surfactant, it reduces the surface tension between water and oil, allowing oils and dirt on the skin or hair to be emulsified and washed away. Its phosphate head group is less aggressive than sulfate head groups, resulting in a gentler cleansing action that preserves the skin's natural moisture barrier.
Pros
Gentle on skin
Compared to common sulfates, TEA-Lauryl Phosphate is less likely to strip natural oils, making it suitable for daily use on sensitive or dry skin.
Effective cleanser
It efficiently removes dirt, excess oil, and makeup without leaving a residue, providing a clean but comfortable feel.
Cons and cautions
Synthetic origin
As a lab-created ingredient, it may not appeal to consumers seeking all-natural or organic formulations.
Potential for mild irritation
While generally mild, a small percentage of users with very reactive skin may experience slight stinging or redness.
Best for
- People with normal to dry skin looking for a gentle cleanser
- Those with sensitive skin who react to sulfates
Use caution if
- Individuals with known allergies to phosphates or triethanolamine
Usage tips
Safety summary
TEA-Lauryl Phosphate is considered safe for use in cosmetics at typical concentrations. It has a low irritation and comedogenic risk, making it suitable for most skin types. However, as with any ingredient, patch testing is recommended for those with known sensitivities.
Research notes
Studies on alkyl phosphate surfactants indicate they are milder than sulfates and less damaging to the skin barrier. While not as extensively studied as some common surfactants, available data supports their safety and efficacy in rinse-off products.
Common label clues
- Typical concentration
- Typically 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics by the FDA and EU CosIng database. Generally recognized as safe when used as directed.
- Common uses
- Facial cleansers, Body washes, Shampoos, Foaming cleansers
- Environmental note
- Phosphate-based surfactants are biodegradable, but their production involves synthetic chemistry. Some sources of lauryl alcohol may be derived from palm oil, so look for sustainably sourced versions if that matters to you.
Good to know
- TEA-Lauryl Phosphate is often used in 'sulfate-free' cleansers as a milder alternative.
- It is biodegradable and considered safe for aquatic environments at typical usage levels.
