Ingredient review
Sodium Ricinoleamidopropyl PG-Dimonium Chloride Phosphate
INCI: SODIUM RICINOLEAMIDOPROPYL PG-DIMONIUM CHLORIDE PHOSPHATE
A gentle, castor-oil-derived surfactant that cleanses without stripping and helps hair feel soft and manageable.
In plain English
This is a mild cleansing and conditioning ingredient made from castor oil. It helps remove dirt and oil from skin and hair without causing dryness or irritation, and it also reduces static and tangles in hair. Think of it as a kinder alternative to harsher detergents like sodium lauryl sulfate.

Quick decision guide
Useful, but context matters
Sodium Ricinoleamidopropyl PG-Dimonium Chloride Phosphate 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 Sodium Ricinoleamidopropyl PG-Dimonium Chloride Phosphate.
- 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 quaternary ammonium compound modified with phosphate and propylene glycol groups, derived from ricinoleic acid (a fatty acid from castor oil). It functions as both a surfactant (cleanser) and a conditioning agent.
How it works
Its molecular structure has a water-loving head and an oil-loving tail, allowing it to surround and lift away dirt and excess oil. The positively charged quaternary group also binds to negatively charged hair and skin surfaces, reducing static, smoothing the cuticle, and leaving a soft, conditioned feel.
Pros
Very gentle on skin and scalp
Unlike harsh sulfates, this surfactant cleanses effectively without stripping natural oils, making it ideal for sensitive or dry skin and for frequent use.
Dual cleansing and conditioning action
It not only removes dirt and oil but also deposits a conditioning film that reduces static and tangles, simplifying your routine by combining two steps.
Cons and cautions
Lower foam volume
It produces a creamier, less bubbly lather than traditional foaming agents, which may feel less satisfying if you prefer a rich, foamy wash.
Often used in blends
Because its cleansing power is mild, it is rarely the sole surfactant in a formula, meaning you may still encounter other detergents in the ingredient list.
Best for
- People with dry, sensitive, or easily irritated skin looking for a gentle cleanser
- Those with frizzy, damaged, or chemically treated hair who want a conditioning shampoo
Use caution if
- Individuals with known allergies to castor oil derivatives (rare) should patch-test first
Usage tips
Safety summary
Considered safe for use in rinse-off and leave-on cosmetics at typical concentrations. Low irritation and sensitization potential. Avoid eye contact with concentrated formulas. Always patch-test if you have known sensitivities.
Research notes
Clinical and safety data support its use as a mild surfactant and conditioning agent. It is well-tolerated in formulations for sensitive skin and is often recommended as a sulfate alternative. Peer-reviewed studies on its specific safety profile are limited but consistent with broader quaternary ammonium surfactant research.
Common label clues
- Typical concentration
- 0.5% to 5% in rinse-off products; lower in leave-ons
- Regulatory status
- Approved for use in cosmetics in the EU, US, and most major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Shampoos, Conditioners, Body washes, Facial cleansers, Leave-on treatments
- Environmental note
- Castor oil is a renewable resource, but the chemical processing may have moderate environmental impact. Biodegradability data is limited but typical for quaternary surfactants.
Good to know
- It is derived from castor oil, a renewable plant source, but the manufacturing process involves chemical modification.
- This ingredient is often listed near the middle or end of an INCI list because it is used at relatively low concentrations.
