Disodium Lauriminobishydroxypropylsulfonate
INCI: Disodium Lauriminobishydroxypropylsulfonate
A gentle, sulfate-free surfactant that cleanses effectively without stripping the skin barrier.
In plain English
Disodium Lauriminobishydroxypropylsulfonate is a synthetic cleansing ingredient that helps remove dirt, oil, and makeup from your skin and hair. Unlike harsh sulfates, it is known for being mild and less likely to cause irritation or dryness, making it a popular choice for sensitive skin and baby products. It works by lowering the surface tension of water so that impurities can be rinsed away easily.

Quick decision guide
Useful, but context matters
Disodium Lauriminobishydroxypropylsulfonate 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 Lauriminobishydroxypropylsulfonate.
- 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 derived from lauric acid (a fatty acid found in coconut oil) and modified with sulfonate groups to improve mildness and water solubility.
How it works
It reduces the surface tension between water and oil, allowing water to mix with and lift away sebum, dirt, and other impurities from the skin and hair. Its large molecular structure makes it less penetrating and therefore less irritating than smaller surfactants like sodium lauryl sulfate.
Pros
Very gentle on skin
Its large molecular structure means it doesn't penetrate deeply into the skin, reducing the risk of irritation and dryness compared to harsher surfactants.
Sulfate-free alternative
Provides effective cleansing without sodium lauryl sulfate or sodium laureth sulfate, making it a good choice for those avoiding sulfates.
Cons and cautions
Synthetic origin
It is manufactured in a lab, which may be a drawback for consumers seeking 100% natural or organic formulations.
Limited environmental data
There is less publicly available research on its biodegradability and aquatic toxicity compared to some older, more studied surfactants.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Anyone seeking sulfate-free hair and body washes
Use caution if
- Individuals who prefer exclusively natural or plant-derived ingredients
Usage tips
Safety summary
Disodium Lauriminobishydroxypropylsulfonate is considered safe for use in cosmetics at typical concentrations. It has low irritation and sensitization potential, making it suitable for sensitive skin and baby products. No significant safety concerns have been raised by regulatory bodies.
Research notes
Research indicates that this surfactant is milder than traditional sulfates, with lower skin irritation and protein denaturation. Most evidence comes from manufacturer safety data and comparative surfactant studies. Peer-reviewed human patch tests confirm low irritation potential.
Common label clues
- Typical concentration
- 1–15% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. Generally recognized as safe when used as directed.
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby care products
- Environmental note
- Synthetic surfactant; limited public data on biodegradability. Some studies suggest sulfonate surfactants can be slow to degrade in certain conditions.
Good to know
- Often listed near the top of ingredient lists in sulfate-free cleansers.
- Can be combined with conditioning agents to reduce any residual tightness after washing.
