Oryza Sativa (Rice) Bran Extract

Overview

Oryza sativa bran extract is an extract from rice bran, the brown outer part of the rice kernel. Rice bran extract is comprised of proteins, lipids, carbohydrates, mineral ash, and water. The content includes palmitic, stearic, oleic, and linoleic acids. Other components include antioxidants such as tocopherols and γ-oryzanol (read about it here: Oryzanol).

This extract acts as an emollient and gives the skin a soft and pleasant feeling upon application. This is mainly due to its content of lipids and fatty acids.

Some research experiments suggest that rice bran extract might have anti-pigment activity, but this theory has so far only been tested on fish, and not humans.

It has also been speculated that this extract can absorb UV light, but this is unconfirmed. It should therefore not be used as a sunscreen without the addition of other UV-blocking ingredients.
