In plain English

TEA-Myristyl Aspartate is a gentle cleansing ingredient made from myristyl alcohol (a fatty alcohol) and aspartic acid (an amino acid). It helps cleansers foam up nicely while being much less harsh than traditional sulfates like SLS. Think of it as a kinder way to wash your face—it removes dirt and oil without leaving your skin feeling tight or dry.

Quick decision guide

Useful, but context matters

TEA-Myristyl Aspartate 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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging TEA-Myristyl Aspartate.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. 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

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

TEA-Myristyl Aspartate is a semi-synthetic surfactant created by combining myristyl alcohol (derived from coconut or palm oil) with aspartic acid (an amino acid). It belongs to the family of amino-acid-based surfactants, known for their mildness and compatibility with sensitive skin.

How it works

In a cosmetic product, this ingredient works by lowering the surface tension between water and oil, allowing dirt and excess sebum to be rinsed away. Its large molecular structure makes it less penetrating than harsher surfactants, so it cleans effectively without disrupting the skin's natural lipid barrier. It also helps stabilize foam, giving cleansers a rich, creamy lather.

Pros

Mild on skin

Unlike sodium lauryl sulfate, this surfactant has a low irritation potential, making it ideal for daily use even on compromised or sensitive skin.

Moisture-friendly

It cleans without stripping natural oils, so your skin stays comfortable and hydrated after washing.

Cons and cautions

Less effective on heavy makeup

If you wear long-wear or waterproof products, you may need a double-cleansing step to fully remove everything.

Cost factor

Products formulated with amino-acid surfactants tend to be pricier than conventional drugstore cleansers.

Best for

  • People with dry or sensitive skin looking for a gentle daily cleanser
  • Anyone wanting to switch to a sulfate-free cleansing routine

Use caution if

  • Those who prefer a very high-foam, squeaky-clean feel (may find this too mild)

Usage tips

Use lukewarm water to activate the lather—hot water can reduce its mildness.
Pair with an oil-based cleanser first if you wear heavy makeup or sunscreen.
Store your cleanser in a cool, dry place to maintain its texture and efficacy.

Safety summary

TEA-Myristyl Aspartate is considered safe for use in rinse-off cosmetics at typical concentrations. It has a low irritation and comedogenic rating, making it suitable for sensitive and acne-prone skin. No significant safety concerns have been reported in cosmetic use.

Research notes

Amino-acid-based surfactants like TEA-Myristyl Aspartate are well-documented in cosmetic science for their mildness and skin compatibility. While specific studies on this exact compound are limited, the broader class is supported by dermatological research showing reduced barrier disruption compared to sulfates.

Common label clues

Typical concentration
1–5% in rinse-off products
Regulatory status
Approved for use in cosmetics in the EU, US, and other major markets. No specific concentration restrictions are imposed, but typical use levels are low.
Common uses
Facial cleansers, Body washes, Shampoos, Makeup removers
Environmental note
Derived from renewable plant sources (coconut or palm oil) and aspartic acid. It is biodegradable, but palm oil sourcing may raise sustainability concerns—look for RSPO-certified ingredients if that matters to you.

Good to know

  • TEA-Myristyl Aspartate is often found in 'sulfate-free' and 'gentle' cleanser formulas.
  • It is biodegradable and considered more environmentally friendly than some traditional surfactants.
