Ingredient review
Lauramidopropyl Hydroxysultaine
INCI: Lauramidopropyl Hydroxysultaine
A gentle, coconut-derived surfactant that cleans without stripping the skin, making it ideal for sensitive or dry skin types.
In plain English
Lauramidopropyl Hydroxysultaine is a mild cleansing agent made from coconut oil. It helps create a rich lather in products like face washes and shampoos, but it's much gentler than traditional soaps. It cleans dirt and oil without leaving your skin feeling tight or dry, which is why it's often used in products for sensitive skin.

Quick decision guide
Useful, but context matters
Lauramidopropyl Hydroxysultaine 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 Lauramidopropyl Hydroxysultaine.
- 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
An amphoteric surfactant, meaning it can act as either a positive or negative ion depending on the pH of the product. It is derived from lauric acid (from coconut oil) and is chemically modified to be very mild on skin.
How it works
It reduces 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 irritating than anionic surfactants like sodium lauryl sulfate, and it also helps stabilize foam and thicken the product formula.
Pros
Very gentle on skin
Its amphoteric nature means it cleans effectively without disrupting the skin's moisture barrier, making it a top choice for sensitive or reactive skin.
Good foam quality
It produces a creamy, stable lather that feels luxurious, unlike some other mild surfactants that produce little to no foam.
Cons and cautions
Not a standalone heavy cleanser
On its own, it may struggle to remove heavy makeup or sunscreen, so it's often combined with other surfactants in formulations.
Potential for mild dryness at high levels
In very high concentrations (above 10%), it can still cause some dryness, though much less than harsher cleansers.
Best for
- People with dry or sensitive skin
- Those looking for a gentle daily cleanser
- Anyone who prefers sulfate-free cleansing products
Use caution if
- Individuals with known coconut oil allergy (rare)
- Those needing a heavy-duty oil cleanser for waterproof makeup
Usage tips
Safety summary
Lauramidopropyl Hydroxysultaine is considered safe for use in cosmetics at typical concentrations. It has a low irritation and sensitization profile, and is not known to be comedogenic. Rare allergic reactions are possible, especially in individuals with coconut oil sensitivity.
Research notes
Studies and safety reviews by the Cosmetic Ingredient Review (CIR) panel have concluded that hydroxysultaines, including this one, are safe in cosmetic formulations. They are well-tolerated on skin and eyes, and their mildness is supported by comparative irritation tests.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics globally, including by the FDA (as part of cosmetic ingredients) and the EU CosIng database. No concentration restrictions in leave-on or rinse-off products.
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby care products
- Environmental note
- Derived from renewable coconut oil and is readily biodegradable, making it a more sustainable choice than many petroleum-based surfactants.
Good to know
- It is biodegradable and considered environmentally friendly compared to some other surfactants.
- It is often used in 'tear-free' baby shampoos because of its low eye irritation potential.
