Ingredient review
Polyglyceryl-3 Rice Branate Phosphate
INCI: Polyglyceryl-3 Rice Branate Phosphate
A mild, eco-friendly emulsifier derived from rice bran that helps create stable, creamy textures without stripping the skin.
In plain English
This ingredient is a helper that allows water and oil to mix smoothly in your skincare products, so you get a consistent, creamy lotion or cleanser. It comes from rice bran (the outer layer of rice grains) and is modified to be extra gentle. It also leaves a light, non-greasy feel on your skin and can help other ingredients absorb better.

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 Polyglyceryl-3 Rice Branate Phosphate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

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 emulsifier made by combining polyglycerol (a plant-derived compound) with fatty acids from rice bran oil and a phosphate group. It is designed to stabilize oil-in-water emulsions.
How it works
It reduces the surface tension between oil and water, allowing them to blend into a stable, uniform cream or lotion. The phosphate group also gives it mild skin-conditioning properties, helping to soften and smooth the skin's surface.
Pros
Gentle on skin
Unlike some harsher emulsifiers, polyglyceryl-3 rice branate phosphate is very mild and unlikely to cause irritation, making it a good choice for sensitive skin.
Eco-friendly profile
It is derived from renewable rice bran and is biodegradable, so it has a lower environmental impact compared to some petroleum-based emulsifiers.
Cons and cautions
Limited water resistance
This emulsifier is best for everyday creams and lotions but may not provide enough water resistance for heavy-duty sunscreens or waterproof products.
Less research available
Compared to classic emulsifiers like glyceryl stearate, there is less published safety and efficacy data, though existing studies are positive.
Best for
- People with normal to dry skin looking for a lightweight moisturizer
- Those who prefer plant-derived, biodegradable ingredients
Use caution if
- Individuals with a known allergy to rice or rice derivatives (rare)
Usage tips
