With a widening range of skincare products in the market, companies are vying for more natural and organic ingredients to integrate to their labels. A more unpopular option is gamma oryzanol. Discover the uses of this organic component here.
What is Gamma Oryzanol?
Gamma oryzanol is found in nature as a component of rice bran oil, wheat bran, corn, barley, and several other fruits and vegetables. Its commercial source is usually rice bran oil which is about 2% gamma oryzanol. While it was originally thought that gamma oryzanol was a single chemical, further research found it to actually be a mixture of sterol and other triterpene esters of ferulic acids.
These ferulic acid esters have antioxidant properties that are equivalent to or better than tocopherol. The oryzanol content of conventionally heated rice bran oil samples remains approximately the same even when heated at 180˚C for 8 hours. However, when the heating at the same conditions was produced by using microwaves, a decrease in oryzanol content was reported.
Gamma oryzanol is synergistic with tocopherol with the optimum ratio being 0.5 gamma oryzanol to 1.0 tocopherol by weight. The antioxidant effect of this mixture is between two and three times greater than either material used alone.
How is Gamma Oryzanol Used
- Gamma Oryzanol is considered to be very safe with only a very low incidence of minor allergic reactions reported.
- A 2014 study concluded that “RB-SCE [supercritical CO2 extraction of rice bran], particularly linoleic acid and γ-oryzanol, promotes hair growth and suggests RB-SCE can be applied as hair loss treatment.”
- Gamma oryzanol has recently been investigated for its ability to slow the progress of melanin pigmentation by intercepting the ultraviolet rays at the skin’s surface and hindering their transmission.
- Gamma Oryzanol is often seen in sunscreens for this reason. It is also able to protect skin lipids from oxidation and has been used to lessen the appearance of freckles, age spots, and skin darkening.
Gamma oryzanol has been used in over sixty products sold in the cosmetics market, especially in sunscreens. Its powerful antioxidant activity can be a benefit in almost any product that has oils sufficient to dissolve it. Typical use levels are 0.5 –2.5% by weight.
