Disodium Lauroamphodiacetate Lauroyl Sarcosinate
INCI: Disodium Lauroamphodiacetate Lauroyl Sarcosinate
A gentle, low-irritation surfactant that cleanses effectively without stripping the skin's natural moisture barrier.
In plain English
This ingredient is a type of mild soap (called a surfactant) that helps water mix with oil and dirt so they can be rinsed away. It's designed to be less harsh than traditional soaps, making it a good choice for sensitive or dry skin. It's often used in products that say 'gentle' or 'non-stripping' on the label.

Quick decision guide
Useful, but context matters
Disodium Lauroamphodiacetate Lauroyl 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 Disodium Lauroamphodiacetate Lauroyl 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
A synthetic surfactant made from lauric acid (a fatty acid found in coconut or palm oil) and sarcosine (an amino acid derivative). It combines two mild cleansing agents to create a gentle, effective cleanser.
How it works
It lowers the surface tension between water and oil, allowing the product to lift away sebum, makeup, and impurities. Its amphoteric (dual-charge) nature makes it less likely to irritate the skin compared to harsher anionic surfactants like sodium lauryl sulfate.
Pros
Very gentle on skin
Its amphoteric structure means it's less likely to cause stinging, redness, or tightness after washing, even for sensitive skin types.
Works well in sulfate-free formulas
It can be used as a primary or secondary cleanser in products that avoid harsh sulfates, giving a creamy, non-stripping lather.
Cons and cautions
Synthetic origin
It is made in a lab, so it may not appeal to consumers looking for 100% naturally derived ingredients.
Moderate cleansing power
On its own, it may not fully remove heavy or waterproof makeup, so it's often paired with other cleansers or oils.
Best for
- People with sensitive or easily irritated skin
- Those who prefer sulfate-free or gentle cleansers
Use caution if
- Individuals who strictly avoid all synthetic ingredients
- Those with known allergies to coconut-derived fatty acids (rare)
