Ingredient review
Lauroamphodipropionic Acid
INCI: Lauroamphodipropionic Acid
A gentle, low-irritation surfactant that cleanses effectively without stripping the skin barrier.
In plain English
Lauroamphodipropionic acid is a mild cleansing ingredient often found in gentle face washes and body cleansers. It helps lift away dirt, oil, and makeup while being much less harsh than traditional soaps or sulfates. Because it is amphoteric (meaning it can work in both acidic and alkaline formulas), it helps maintain a comfortable pH on your skin and reduces the risk of dryness or irritation.

Quick decision guide
Useful, but context matters
Lauroamphodipropionic Acid 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 Lauroamphodipropionic Acid.
- 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, amphoteric surfactant derived from lauric acid (a fatty acid found in coconut oil) and modified with amino acid-like groups to make it extra mild.
How it works
It reduces the surface tension between water and oil, allowing impurities to be rinsed away. Its amphoteric nature means it adjusts to the pH of your skin, making it less likely to disrupt the natural barrier compared to harsher anionic surfactants like sodium lauryl sulfate.
Pros
Very gentle on skin
Its amphoteric structure makes it one of the mildest surfactants, ideal for sensitive or reactive skin types.
pH-friendly
Works well across a range of pH levels, helping cleansers stay close to skin's natural pH (around 5.5) for less irritation.
Cons and cautions
Lower foam volume
Produces less lather than sulfates, which some users may perceive as less effective even though cleansing power remains good.
Potential for mild stinging
If your skin barrier is damaged or very inflamed, even mild surfactants can cause temporary stinging.
Best for
- People with dry or sensitive skin looking for a non-stripping cleanser
- Anyone seeking a sulfate-free cleansing option
Use caution if
- Individuals with known allergies to coconut-derived ingredients (though rare)
Usage tips
Safety summary
Lauroamphodipropionic acid is considered safe for use in rinse-off cosmetics at typical concentrations. It has a low irritation and sensitization profile, making it suitable for sensitive skin and baby care. As with any ingredient, patch test if you have a history of reactions to coconut-derived compounds.
Research notes
Amphoteric surfactants like lauroamphodipropionic acid are well-studied for their mildness and compatibility with skin. Research supports their low irritation potential compared to anionic surfactants, though specific studies on this exact compound are limited. It is widely accepted by cosmetic safety panels.
Common label clues
- Typical concentration
- Typically 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. No specific restrictions at typical use levels.
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby care products
- Environmental note
- Synthetic but generally considered biodegradable. Derived from lauric acid, which can be sourced from sustainable coconut oil.
Good to know
- Often used alongside other mild surfactants like cocamidopropyl betaine to boost foam and stability.
- Commonly found in baby shampoos because of its low irritation potential.
