Ingredient review
Ricinolamidopropyl Betaine
INCI: RICINOLEAMIDOPROPYL BETAINE
A gentle, castor oil-derived surfactant that cleanses effectively with low irritation potential, ideal for sensitive skin.
In plain English
This ingredient is a mild cleansing agent made from castor oil. It helps create a nice lather in cleansers and shampoos while being much gentler than traditional harsh soaps. Because it's derived from a plant source and designed to be kind to skin, it's often used in products for sensitive or dry skin.

Quick decision guide
Useful, but context matters
Ricinolamidopropyl Betaine 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 Ricinolamidopropyl Betaine.
- 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
Ricinolamidopropyl betaine is a semi-synthetic surfactant, meaning it's made by chemically modifying a natural fatty acid (ricinoleic acid from castor oil) to create a mild, amphoteric (can act as both an acid and a base) cleansing molecule.
How it works
In a cosmetic product, this molecule has a water-loving head and an oil-loving tail. When you wash, the oil-loving tail grabs onto dirt, oil, and makeup, while the water-loving head allows the whole mess to be rinsed away with water. Its amphoteric nature makes it gentle on skin because it doesn't disrupt the skin's natural barrier as much as harsher surfactants.
Pros
Very gentle on skin
Its amphoteric structure means it cleans without stripping the skin's natural moisture barrier, making it suitable for sensitive or eczema-prone skin.
Plant-derived and biodegradable
Sourced from castor oil, it is a renewable resource and generally considered more environmentally friendly than purely synthetic surfactants.
Cons and cautions
Mild cleansing only
It may not thoroughly remove heavy, waterproof makeup or long-wear sunscreen on its own, often requiring a double-cleansing method.
Potential for slight dryness at high levels
In formulas with very high concentrations (above 10%), some users may experience mild tightness or dryness, though this is rare.
Best for
- People with sensitive or dry skin
- Those looking for a sulfate-free cleanser
- Anyone wanting a gentle daily face wash
Use caution if
- Individuals with known castor oil allergy (rare)
- Those seeking a single-ingredient heavy-duty makeup remover
Usage tips
Safety summary
Ricinolamidopropyl betaine is considered safe for use in rinse-off cosmetics at typical concentrations. It has a low irritation and sensitization potential, making it a preferred choice for gentle formulations. No significant safety concerns have been raised by regulatory bodies.
Research notes
Research on ricinolamidopropyl betaine is limited but consistent with the broader family of amidopropyl betaines, which are well-studied and recognized as mild, low-irritation surfactants. Studies on similar betaines show they cause less skin barrier disruption than sulfates.
Common label clues
- Typical concentration
- 1% to 10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics globally, including by the EU CosIng database and the US FDA (as part of the generally recognized as safe surfactant family).
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby care products
- Environmental note
- Derived from castor oil, a renewable plant source. It is generally biodegradable, but always check the full product formulation for environmental impact.
Good to know
- It is often used alongside other mild surfactants to boost foam without increasing irritation.
- The 'betaine' part refers to its chemical structure, not the dietary supplement betaine.
