INCI: TEA-Lauroyl Methyl Beta-Alaninate

A gentle, amino-acid-based surfactant that cleanses effectively while being kind to sensitive skin.

beautyskincarecleanser

In plain English

This is a mild cleansing ingredient made from lauric acid (found in coconut oil) and beta-alanine (an amino acid). It helps remove dirt, oil, and makeup from your skin without stripping away its natural moisture barrier. Unlike harsher sulfates, it leaves skin feeling soft and comfortable after washing.

Quick decision guide

Useful, but context matters

TEA-Lauroyl Methyl Beta-Alaninate 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-Lauroyl Methyl Beta-Alaninate.
  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-Lauroyl Methyl Beta-Alaninate is a synthetic surfactant derived from lauric acid and the amino acid beta-alanine. It belongs to the family of acyl amino acid surfactants, known for their gentle cleansing properties and good foaming ability.

How it works

It works by reducing the surface tension between water and oil, allowing dirt and excess sebum to be rinsed away. Its molecular structure is large and mild, so it cleans without penetrating deeply into the skin or disrupting the lipid barrier, which helps maintain hydration.

Pros

Mild on skin

Its large molecular structure means it cleans without penetrating the skin barrier, reducing irritation risk for sensitive or dry skin types.

Good foam quality

Produces a satisfying, creamy lather that feels luxurious without the harshness of traditional sulfates.

Cons and cautions

Potential for slight dryness

In very high concentrations or in leave-on products, it may still cause mild dryness for extremely dehydrated skin.

Less lather than sulfates

Some users accustomed to the rich foam of sodium lauryl sulfate may find the lather less voluminous.

Best for

  • People with dry or sensitive skin
  • Those looking for a sulfate-free cleanser

Use caution if

  • Individuals with known allergies to coconut-derived ingredients (rare)

Usage tips

Use in rinse-off cleansers for best results; avoid high concentrations in leave-on products.
Pair with other mild surfactants like cocamidopropyl betaine to boost foam and gentleness.

Safety summary

TEA-Lauroyl Methyl Beta-Alaninate is considered safe for cosmetic use with low irritation and comedogenic potential. It is well-tolerated by most skin types, including sensitive skin.

Research notes

Amino-acid-based surfactants like this one have been studied for their mildness and ability to preserve skin barrier function. While not as extensively researched as sulfates, available data supports their safety and gentleness.

Common label clues

Typical concentration
Typically 5–15% in rinse-off cleansers
Regulatory status
Approved for use in cosmetics in the EU, US, and other major markets; generally recognized as safe at typical concentrations.
Common uses
Facial cleansers, Body washes, Shampoos, Makeup removers
Environmental note
Biodegradable and derived from renewable sources (coconut oil and amino acids), making it a more sustainable surfactant choice.

Good to know

  • Often found in 'amino acid' cleansers marketed for sensitive skin.
  • It is biodegradable and considered environmentally friendlier than some traditional surfactants.
