Ingredient review
TEA-Palm Kernel Sarcosinate
INCI: TEA-Palm Kernel Sarcosinate
A gentle, sulfate-free surfactant that cleanses effectively while being kind to sensitive skin.
In plain English
This ingredient is a mild soap-like molecule that helps water mix with oil and dirt so they can be rinsed away. It's made from palm kernel oil (a plant fat) and sarcosine (a natural amino acid derivative). Unlike harsh sulfates, it cleans without stripping your skin's natural moisture barrier, making it a good choice for dry or sensitive skin.

Quick decision guide
Useful, but context matters
TEA-Palm Kernel Sarcosinate 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-Palm Kernel Sarcosinate.
- 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-Palm Kernel Sarcosinate is a surfactant created by combining palm kernel fatty acids with sarcosine, then neutralizing with triethanolamine (TEA). It belongs to the sarcosinate family of cleansers, known for being gentle and non-irritating.
How it works
As a surfactant, it reduces the surface tension between water and oil, allowing impurities and excess sebum to be lifted from the skin and washed away. Its molecular structure is larger and less penetrating than sulfates, so it cleans without disrupting the skin's lipid barrier.
Pros
Mild on skin
Its large molecular structure means it cleans without penetrating deep into the skin, reducing the risk of irritation and dryness.
Sulfate-free option
Provides effective cleansing without the harshness of sodium lauryl sulfate, making it suitable for daily use on sensitive or compromised skin.
Cons and cautions
Palm oil sourcing
Palm kernel oil is a common source, and unless certified sustainable, its production can contribute to deforestation and habitat loss.
TEA content
Triethanolamine (TEA) can be a mild irritant in high concentrations, though levels in rinse-off products are generally considered safe by regulators.
Best for
- People with dry or sensitive skin looking for a mild cleanser
- Those avoiding sulfates like SLS or SLES
Use caution if
- Individuals with a known allergy to palm-derived ingredients or TEA
Usage tips
Safety summary
TEA-Palm Kernel Sarcosinate is considered safe for use in rinse-off cosmetics at typical concentrations. The TEA content is low enough to pose minimal risk, and the ingredient is non-irritating and non-comedogenic for most skin types.
Research notes
Sarcosinate surfactants have been studied for their mildness and low irritation potential compared to traditional sulfates. The Cosmetic Ingredient Review has reviewed sarcosinates and found them safe for cosmetic use. No significant safety concerns have been raised for this specific compound.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. The Cosmetic Ingredient Review (CIR) panel has deemed sarcosinates safe as used in rinse-off products.
- Common uses
- Facial cleansers, Body washes, Shampoos, Makeup removers
- Environmental note
- Palm kernel oil sourcing can impact rainforests; look for products with RSPO-certified sustainable palm oil to reduce environmental footprint.
Good to know
- Sarcosinates are naturally derived from amino acids and are known for their compatibility with sensitive skin.
- This ingredient is biodegradable, making it a more environmentally friendly choice compared to some synthetic surfactants.
