What Is Defatted Rice Bran Extract?
Defatted Rice Bran Extract comes from the outer layer of rice kernels, known as rice bran, after most of its natural oil has been removed. This bran is rich in compounds like ferulic acid, gamma-oryzanol, B vitamins and proteins that remain even after defatting. Historically rice bran was discarded or used as animal feed until researchers found that its antioxidants and skin-friendly nutrients could benefit cosmetic formulas. To create the extract, producers separate the bran during milling, remove the oil through cold pressing or gentle solvent washing, then steep the defatted bran in water or a mix of water and food-grade solvents. The resulting liquid is filtered and concentrated to yield a skin-compatible extract. You will most often spot it in brightening serums, anti-aging creams, sheet masks, lightweight lotions, deodorant sticks and gentle cleansers.
Defatted Rice Bran Extract’s Cosmetic Benefits/Uses
When added to skincare or personal care products this extract brings several useful properties:

- Deodorant: Naturally tackles the molecules that cause unwanted odor making it valuable in underarm products foot sprays and freshening body lotions
Defatted Rice Bran Extract is generally considered friendly for all skin types, including oily, combination, normal and dry. Its lightweight water-based nature means it will not clog pores or leave a greasy finish so even acne-prone users often tolerate it well. Sensitive skin usually handles the extract without trouble thanks to its mild profile, though anyone with a known rice or grain allergy should proceed cautiously.
The ingredient is plant-derived with no animal by-products, making it suitable for vegans and vegetarians. Most manufacturers also avoid animal testing, although shoppers should confirm a product’s cruelty-free status on a brand-by-brand basis.
No data suggest that topical use poses specific risks for pregnant or breastfeeding women. That said, this is not medical advice and anyone who is expecting or nursing should run new skincare products past a qualified healthcare professional to be on the safe side.
Defatted Rice Bran Extract does not increase photosensitivity, so it will not make skin more prone to sunburn. Standard daytime UV protection is still recommended with any routine.

Comedogenic Rating
Rating: 0–1 out of 5. Defatted Rice Bran Extract is largely water soluble and stripped of most oils, so it is unlikely to sit in pores or create the waxy build-up that can lead to blackheads. Its lightweight profile and absence of heavy fatty acids keep the clogging potential very low, though trace lipids may explain why it is not a perfect zero. Overall this extract is considered safe for acne-prone or breakout-prone skin.
Because the ingredient is usually added at modest percentages and paired with water-based carriers its comedogenic impact in finished products is minimal.
