Rice Bran Oil Polyglyceryl-3 Esters
INCI: Rice Bran Oil Polyglyceryl-3 Esters
A mild, eco-friendly emulsifier that helps blend oil and water in formulas while leaving skin feeling soft.
In plain English
This ingredient is a modified version of rice bran oil, combined with polyglycerin to create a substance that can mix oil and water together. In skincare, it acts as an emulsifier, meaning it helps creamy products stay smooth and not separate. It also leaves a light, non-greasy feel on the skin and is considered very gentle, even for sensitive skin types.

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 ester formed by reacting rice bran oil fatty acids with polyglycerin-3. It functions primarily as a non-ionic emulsifier and mild skin conditioning agent.
How it works
It reduces the surface tension between oil and water phases in a formula, allowing them to blend into a stable emulsion. On the skin, it deposits a thin, moisturizing film that helps soften and smooth the surface without clogging pores.
Pros
Gentle on skin
Rated very low on irritation scales, making it a safe choice for sensitive skin and around the eye area.
Eco-friendly profile
Derived from renewable rice bran oil and biodegradable, aligning with sustainable beauty preferences.
Cons and cautions
Limited standalone efficacy
As an emulsifier, its main role is in formulation; it doesn't provide dramatic skin benefits on its own.
Potential incompatibility
May require co-emulsifiers in very low-viscosity or high-oil formulas, which can complicate DIY formulations.
Best for
- People with sensitive or reactive skin looking for gentle emulsifiers
- Those who prefer plant-derived ingredients in their skincare
Use caution if
- Individuals with a known allergy to rice or rice derivatives (rare)
Usage tips
