Ingredient review
Sodium Taurine Lauroyl Methyl Beta-Alaninate
INCI: Sodium Taurine Lauroyl Methyl Beta-Alaninate
A gentle, amino-acid-based surfactant that cleanses without stripping the skin's natural moisture barrier.
In plain English
This ingredient is a mild cleansing agent made from taurine (an amino acid) and lauric acid (from coconut). It helps remove dirt, oil, and makeup without leaving your skin feeling tight or dry. Unlike harsher sulfates, it's known for being kind to sensitive skin.

Quick decision guide
Easy yes for most routines
Sodium Taurine 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.
- Step 1Start with the score, then check the irritation and clogging risk before judging Sodium Taurine Lauroyl Methyl Beta-Alaninate.
- 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
Sodium Taurine Lauroyl Methyl Beta-Alaninate is a semi-synthetic surfactant derived from taurine, an amino acid naturally found in the body, and lauric acid from coconut oil. It belongs to the family of amino-acid-based cleansers, which are prized for their mildness.
How it works
As a surfactant, it reduces the surface tension between water and oil, allowing impurities to be rinsed away. Its molecular structure is large and gentle, so it cleanses effectively without penetrating deeply into the skin or disrupting the lipid barrier.
Pros
Very gentle on skin
Its large molecular structure means it cleanses without penetrating the skin barrier, reducing the risk of irritation and dryness.
Sulfate-free alternative
Provides effective cleansing without sodium lauryl sulfate (SLS) or sodium laureth sulfate (SLES), which can be harsh for sensitive skin.
Cons and cautions
Lower foaming action
Produces a creamy, low lather that some users may mistake for not cleaning effectively, though it still removes dirt and oil well.
Higher cost
Amino-acid surfactants are more expensive to produce, so products containing them often carry a higher price tag.
Best for
- People with dry, sensitive, or eczema-prone skin
- Anyone looking for a sulfate-free, gentle daily cleanser
Use caution if
- Those who prefer a high-foam, squeaky-clean feel (this produces a lower, creamier lather)
Usage tips
Safety summary
Sodium Taurine Lauroyl Methyl Beta-Alaninate is considered safe for use in cosmetics. It has low irritation and sensitization potential, making it suitable for sensitive skin. No significant safety concerns have been reported in regulatory reviews.
Research notes
Amino-acid surfactants like this one have been studied for their mildness and compatibility with skin. Research indicates they cause less barrier disruption and protein denaturation compared to traditional anionic surfactants. However, specific studies on this exact compound are limited, with safety largely inferred from the broader class.
Common label clues
- Typical concentration
- 1–15% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No known restrictions at typical concentrations.
- Common uses
- Facial cleansers, Body washes, Shampoos, Micellar waters
- Environmental note
- Derived from renewable plant sources (coconut) and amino acids. It is biodegradable and considered more environmentally friendly than some petroleum-based surfactants.
Good to know
- This ingredient is often listed near the top of the ingredient list in gentle cleansers, indicating it's a primary surfactant.
- It is compatible with other mild surfactants and is often blended to adjust foam and texture.
