Potassium Palmitoyl Hydrolyzed Rice Protein
INCI: Potassium Palmitoyl Hydrolyzed Rice Protein
A mild, amino-acid-based surfactant that cleanses without stripping the skin or hair, making it ideal for sensitive or dry types.
In plain English
This ingredient is a gentle cleanser made by attaching a fatty acid from palm oil to a protein from rice. It helps remove dirt and oil without stripping your skin's natural moisture barrier, leaving skin and hair feeling soft rather than tight or dry.

Quick decision guide
Easy yes for most routines
Potassium Palmitoyl Hydrolyzed Rice Protein 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 Potassium Palmitoyl Hydrolyzed Rice Protein.
- 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 surfactant created by chemically bonding palmitic acid (a fatty acid from palm oil) with hydrolyzed rice protein. It belongs to the class of amino-acid surfactants known for their mildness.
How it works
It works by reducing the surface tension between water and oil, allowing dirt and sebum to be rinsed away. Unlike harsher sulfates, it has a larger molecular structure that is less penetrating and more skin-friendly, so it cleanses without disrupting the skin barrier.
Pros
Extremely gentle on skin
Its large molecular structure means it doesn't penetrate the skin barrier, reducing irritation and dryness compared to sulfates.
Moisturizing effect
The rice protein component leaves a light conditioning film on skin and hair, helping to retain moisture after washing.
Cons and cautions
Lower foam volume
It produces a creamy, low lather that some users may perceive as less effective, even though it cleanses well.
Palm oil sourcing
Palmitic acid is often derived from palm oil, which can be associated with deforestation unless certified sustainable.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Those with color-treated or damaged hair who want a mild shampoo
Use caution if
- Individuals seeking a high-foam, deep-cleansing experience may find it too gentle
Usage tips
Safety summary
Considered safe for topical use with very low irritation and sensitization potential. No significant safety concerns reported in cosmetic concentrations.
Research notes
Amino-acid surfactants like this one are well-studied for mildness and skin compatibility. Rice protein adds additional moisturizing and film-forming benefits, though specific clinical studies on this exact compound are limited.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics worldwide, including by the EU CosIng database and the US FDA as a safe surfactant.
- Common uses
- Facial cleansers, Shampoos, Body washes, Conditioners
- Environmental note
- Derived from renewable plant sources, but palm oil sustainability depends on certification (e.g., RSPO). Biodegradable and generally considered eco-friendly.
Good to know
- This ingredient is often listed near the top of ingredient lists in sulfate-free cleansers.
- It is compatible with other mild surfactants to boost foam without increasing irritation.
