Ingredient review
Disodium Lauriminodipropionate
INCI: Disodium Lauriminodipropionate
A gentle, low-irritation surfactant that effectively cleanses without stripping the skin's natural moisture barrier.
In plain English
Disodium Lauriminodipropionate is a mild cleansing ingredient that helps remove dirt, oil, and makeup from your skin. Unlike harsher detergents like sodium lauryl sulfate, it is designed to be gentle and less likely to cause dryness or irritation. It works by attracting both water and oil, allowing impurities to be rinsed away easily. You'll often find it in sulfate-free cleansers and products for sensitive skin.

Quick decision guide
Useful, but context matters
Disodium Lauriminodipropionate 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 Lauriminodipropionate.
- 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
Disodium Lauriminodipropionate is a synthetic, amphoteric surfactant derived from lauric acid (a fatty acid found in coconut or palm oil). It belongs to the iminodipropionate family and is known for its mildness and compatibility with other cleansing ingredients.
How it works
As an amphoteric surfactant, it carries both positive and negative charges, which allows it to work effectively across a range of pH levels. It reduces the surface tension between water and oil, helping to lift and suspend dirt and sebum so they can be rinsed away. Its mild charge also makes it less likely to bind strongly to skin proteins, reducing irritation potential.
Pros
Very gentle on skin
Its amphoteric nature means it is less likely to cause stinging, redness, or dryness compared to anionic surfactants like SLS.
Sulfate-free friendly
It works well in sulfate-free cleansers, providing effective cleansing without the harshness associated with traditional foaming agents.
Cons and cautions
Synthetic origin
It is manufactured in a lab, which may be a drawback for consumers seeking 100% natural or minimally processed ingredients.
Limited standalone cleansing power
On its own, it may not remove heavy, waterproof makeup or long-wearing sunscreen as effectively as stronger surfactants.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Anyone wanting to avoid harsh sulfates in their skincare routine
Use caution if
- Those who prefer exclusively natural or plant-derived ingredients may want to check the full formulation
Usage tips
Safety summary
Disodium Lauriminodipropionate is considered safe for use in cosmetics at typical concentrations. It has low irritation and sensitization potential, making it a good choice for sensitive skin. No significant safety concerns have been raised by regulatory bodies.
Research notes
Research on iminodipropionate surfactants indicates they are mild to the skin and eyes, with low acute toxicity. Most safety data comes from industry-sponsored studies and regulatory reviews rather than independent clinical trials.
Common label clues
- Typical concentration
- 1–10% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. The Cosmetic Ingredient Review (CIR) panel has reviewed similar iminodipropionates and found them safe as used.
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby care products
- Environmental note
- Synthetic but biodegradable; sourcing of lauric acid may involve palm oil, so look for sustainably sourced formulations if that is a concern.
Good to know
- Disodium Lauriminodipropionate is often used alongside other mild surfactants like cocamidopropyl betaine to create a balanced, non-stripping formula.
- It is considered biodegradable and generally safe for aquatic life at typical use concentrations.
