Ingredient review
Disodium Oleoamphodipropionate
INCI: Disodium Oleoamphodipropionate
A gentle, amphoteric surfactant that cleanses effectively without stripping the skin, making it a great choice for sensitive or dry skin types.
In plain English
Disodium Oleoamphodipropionate is a mild cleansing ingredient made from oleic acid, a fatty acid found in olive oil and other plant oils. It belongs to a class of surfactants called amphoterics, which means it can work well in both acidic and alkaline formulas. Unlike harsher sulfates, it cleanses without stripping away your skin's natural moisture barrier, leaving skin feeling soft and comfortable. You'll often find it in gentle, sulfate-free cleansers, baby washes, and products for sensitive skin.

Quick decision guide
Useful, but context matters
Disodium Oleoamphodipropionate 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 Oleoamphodipropionate.
- 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 semi-synthetic, amphoteric surfactant derived from oleic acid (a fatty acid from plant oils). It is often used as a secondary surfactant to boost foam and improve mildness in cleansing formulas.
How it works
It reduces the surface tension between water and oil, allowing dirt, excess sebum, and makeup to be rinsed away. Because it is amphoteric, it remains gentle on the skin and helps counteract the potential irritation from stronger primary surfactants like sodium lauryl sulfate.
Pros
Very gentle on skin
Its amphoteric nature makes it one of the mildest surfactants, ideal for compromised or sensitive skin barriers.
Improves foam in gentle formulas
It helps create a rich, creamy lather even in sulfate-free cleansers, making the washing experience more pleasant.
Cons and cautions
Limited cleansing power alone
On its own, it may not remove heavy makeup or waterproof sunscreen effectively, so it is usually paired with other cleansers.
Semi-synthetic origin
While derived from natural fatty acids, it undergoes chemical processing, which may not suit consumers seeking fully natural ingredients.
Best for
- People with dry, sensitive, or eczema-prone skin looking for a gentle cleanser
- Anyone seeking a sulfate-free, mild foaming cleanser for daily use
Use caution if
- Those who prefer exclusively natural or plant-derived ingredients (since it is semi-synthetic)
Usage tips
Safety summary
Disodium Oleoamphodipropionate is considered safe for use in cosmetics at typical concentrations. It has low irritation and sensitization potential, making it suitable for sensitive skin. No significant safety concerns have been raised by regulatory bodies.
Research notes
Studies on amphoteric surfactants, including this ingredient, show they are significantly milder than anionic surfactants like SLS. Research supports their use in reducing skin barrier disruption and irritation in cleansing products.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. The Cosmetic Ingredient Review (CIR) panel has deemed it safe as used in rinse-off products.
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby care products
- Environmental note
- Derived from renewable plant oils and considered biodegradable, though the manufacturing process involves chemical modification.
Good to know
- Disodium Oleoamphodipropionate is often listed near the middle or end of an ingredient list, indicating it is used at lower concentrations.
- It is considered biodegradable and generally safe for aquatic life at typical use levels.
