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 created by combining fatty acids from rice oil with diglycerin. It is part of a newer generation of mild, plant-based emulsifiers designed to replace harsher alternatives.
How it works
It sits at the boundary between water and oil droplets in a formula, reducing surface tension so they stay blended. This creates a stable, creamy texture. It also deposits a thin, moisturizing film on the skin, helping to prevent water loss.
Pros
Gentle on skin
Derived from rice oil and diglycerin, it is very mild and unlikely to cause irritation, making it suitable for sensitive skin.
Improves texture
It helps create a smooth, creamy product that spreads easily and leaves a soft, non-greasy feel on the skin.
Cons and cautions
Limited versatility
Works best in standard oil-in-water emulsions; may require co-emulsifiers for very thin or very thick formulas.
Less studied
Compared to classic emulsifiers like glyceryl stearate, there is less published research on its long-term skin effects.
Best for
- Anyone looking for a gentle, plant-derived emulsifier in their moisturizer or cleanser
- People with sensitive or dry skin who want a non-stripping, conditioning formula
Use caution if
- Those with a known allergy to rice or rice-derived ingredients (very rare)
