What it is
TEA-Lauroyl Methylaminopropionate is a synthetic surfactant derived from lauric acid and the amino acid methylaminopropionic acid. It belongs to the family of amino-acid surfactants, known for their mildness and compatibility with sensitive skin.
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 gentle, so it cleans without penetrating deeply into the skin barrier or disrupting natural moisture levels.
Pros
Gentle on skin
Its large molecular structure means it cleans without penetrating the skin barrier, reducing the risk of irritation and dryness.
Maintains moisture
Unlike harsher sulfates, this surfactant helps preserve the skin's natural oils, leaving it feeling soft and hydrated after washing.
Cons and cautions
Limited cleansing power
It may struggle to remove heavy makeup or waterproof sunscreen, often requiring a double-cleansing routine.
Synthetic origin
While safe, it is not a naturally derived ingredient, which might be a consideration for those preferring plant-only formulas.
Best for
- People with dry or sensitive skin looking for a non-stripping cleanser
- Those with eczema or rosacea who need a very gentle wash
Use caution if
- Individuals seeking a deep-cleansing, foaming experience may find it too mild
