Lauriminodipropionic Acid
INCI: Lauriminodipropionic Acid
A gentle, low-irritation surfactant that cleanses effectively without stripping the skin's natural moisture barrier.
In plain English
Lauriminodipropionic acid is a mild cleansing ingredient used in soaps and washes. It helps remove dirt and oil without making your skin feel tight or dry. Think of it as a kinder alternative to harsh detergents like sodium lauryl sulfate.

Quick decision guide
Useful, but context matters
Lauriminodipropionic 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 Lauriminodipropionic 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
Lauriminodipropionic acid is an amphoteric surfactant, meaning it can act as both a mild acid and a base. It is derived from lauric acid, a fatty acid found in coconut oil and palm kernel oil, and is often used in gentle cleansing formulas.
How it works
It works by reducing the surface tension of water, allowing oils and dirt to be lifted away from the skin and rinsed off. Because it is amphoteric, it is less likely to disrupt the skin's natural pH and lipid barrier compared to harsher anionic surfactants.
Pros
Gentle on skin
Its amphoteric nature means it cleanses without stripping the skin's natural oils, making it ideal for daily use and sensitive skin.
Low irritation risk
Clinical and anecdotal evidence suggests it causes less stinging and redness compared to common sulfates, especially around the eyes.
Cons and cautions
Potential for mild dryness at high levels
In very concentrated formulas, it can still cause slight tightness, so it's often blended with other mild surfactants.
Limited independent research
While safety data exists, there are fewer peer-reviewed studies on this specific ingredient compared to more common surfactants.
Best for
- People with sensitive or easily irritated skin
- Those looking for a sulfate-free, gentle cleanser
Use caution if
- Individuals with known allergies to coconut-derived ingredients (though rare)
Usage tips
Safety summary
Lauriminodipropionic acid is considered safe for use in cosmetics at typical concentrations. It has a low irritation and comedogenic profile, making it suitable for sensitive skin. No significant safety concerns have been reported in regulatory reviews.
Research notes
The Cosmetic Ingredient Review (CIR) panel has evaluated lauriminodipropionic acid and concluded it is safe for use in cosmetics. Most evidence comes from safety assessments rather than large-scale clinical efficacy trials, but its mildness is well-documented in surfactant chemistry literature.
Common label clues
- Typical concentration
- 1–10% in rinse-off products; lower in leave-on formulations
- Regulatory status
- Approved for use in cosmetics by the FDA and the European Commission. The Cosmetic Ingredient Review (CIR) panel has deemed it safe as used in rinse-off and leave-on products.
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby care products
- Environmental note
- Derived from renewable plant sources (coconut or palm kernel oil), but palm oil sourcing can raise sustainability concerns. Look for RSPO-certified palm derivatives when possible.
Good to know
- It is often used in 'no-tears' baby shampoos due to its mildness.
- It can help improve the feel of foam, making it creamier and more luxurious.
