Ethylhexyl ferulate is a ferulic acid derivative which has superior antioxidant/UV absorbent properties, is easy to handle and thermally stable. The ferulic acid esters are preferably used as a component in cosmetics such as sun oil,hair spray, anti-wrinkle essence, etc.
Fuction:
Ferulic acid is useful as raw material for medicines, agricultural chemicals, cosmetics, dyes, and foods. However it does not have sufficient antioxidant and ultraviolet (UV) absorbent properties. Further, ferulic acid turns yellow when dissolved in an alkaline solution, and degrades when allowed to stand in air for a long period of time. Meanwhile, 2-ethylhexyl p-methoxycinnamate, is used as a UV absorbent in cosmetics. However, it is thermally unstable, and does not exhibit sufficient antioxidant property. The present inventors have made studies on antioxidant/UV absorbents easy to handle, thermally stable, which can be suitably used in cosmetics and found that certain esters of ferulic acid with certain alkanols exhibit such desirable properties. The most preferred alkyl group is 2-ethylhexyl. 2-ethylhexyl ferulate has an improved thermal stability over ferulic acid and 2-ethylhexyl p-methoxycinnamate. Its main functions are whitening, anti-aging, antioxidant and UV absorbent.
