Rice Bran Wax Ethyl Esters
INCI: Rice Bran Wax Ethyl Esters
A gentle, plant-based emollient that helps create a smooth, non-greasy feel in skincare and makeup, with a very low risk of irritation.
In plain English
Rice bran wax ethyl esters are a natural ingredient made from rice bran wax. In skincare and makeup, they act as a soft, silky emollient that helps products spread easily and feel smooth on the skin. They also help stabilize formulas and can create a light, protective film that locks in moisture without feeling heavy or greasy. Because they are derived from rice, they are a popular choice for plant-based and gentle formulations.

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
Rice bran wax ethyl esters are a modified wax derived from rice bran oil. Through a process called esterification, the natural wax is transformed into a more stable, emollient-rich ingredient that feels lighter and more spreadable than the original wax.
How it works
In a cosmetic product, rice bran wax ethyl esters sit on the surface of the skin, forming a thin, breathable film. This film helps reduce water loss (keeping skin hydrated) while providing a smooth, silky slip that makes the product easy to apply. It also helps thicken and stabilize emulsions, preventing separation and improving the overall texture.
Pros
Silky, non-greasy feel
Unlike heavier waxes or oils, rice bran wax ethyl esters provide a smooth, silky texture that doesn't leave a sticky or greasy residue, making it pleasant for daily use.
Gentle for sensitive skin
This ingredient has a very low irritation and comedogenic risk, so it's unlikely to clog pores or cause breakouts, even for those with reactive skin.
Cons and cautions
Rare allergy concern
Although extremely uncommon, individuals with a rice allergy may react to this ingredient. Always patch test if you have known food allergies.
Texture may vary by formula
In very high concentrations, it can make a product feel slightly waxy or heavy, so formulators must balance it with lighter ingredients for a perfect feel.
Best for
- Anyone looking for a gentle, plant-based emollient in their moisturizer or lip balm
- People with dry or normal skin who want a non-greasy way to seal in hydration
Use caution if
- Individuals with a known allergy to rice or rice-derived ingredients (very rare)
