By objective test methods Ferulic acid could demonstrate following mode of actions:
- A sunscreen effect
- A deodorant action
- An antioxidative effectiveness
- An anti-inflammatory effectiveness
1. A sunscreen effect: Ferulic acid and its esters like chemical sunscreen agents have a phenyl-2-propene structure that means, they have a vinylgroup at the benzene ring, which is strongly absorbing UV-light. By this absorption the stabilized phenoxy radical will be formed and later on a cis-trans-isomerization will occur. By this mode of action ferulic acid in barks, leaves and seeds is protecting the plant from the harmful rays of sunlight. Ferulic acid and their esters show a maximum of UV-absorption at 280nm and 340nm. By addition of 0.2 - 0.5 % Ferulic acid a sun protection factor of 3 - 5 can be achieved.
2. A deodorant effect: Deodorants may act as antimicrobials especially against those Gram-positive germs which may de- compose the sweat or they may inhibit the microbial enzymes, which ar finally responsible for the decom- position of the sweat. The minimal inhibition concentration MIC of Ferulic acid is 0.25 % for the Gram-positive germs and 0.37- 0.45 % for the Gram-negative strains.
3. An antioxidative effectiveness: An addition of Ferulic acid is able to prevent the de- velopment of radicals started by oxygen and UV-ra- diation. Each reactive radical Lx or L-O-O-x (lipoper- oxyl radical) which might get contact with a molecule of ferulic acid abstracts a hydrogen atom from the phenolic group of ferulic acid. A phenoxyradical is generated, which shows a high resonance stabilization. Therefore ferulic acid is ap- proved as an antioxidant agent in cosmetics and in food. Ferulic acid and amino acids or dipeptides form mixtures with synergistic antioxidative effects against peroxidation of unsaturated fatty acids and fats of all kind.
4. An anti-inflammatory effectiveness The effect of many anti-inflammatory agents is based on their influence on mediators of inflammable reactions. Oxygen radicals belong to these mediators. The anti-inflammatory effectiveness of ferulic acid is based on its antioxidative potential. It is proved by the caragenin model at the paws of rats. It is also easy to explain that Ferulic acid is able to interfere in the cycles which is responsible for forming dandruff. The effect against itching, which is mentioned in a patent, may be explained by the anti-inflammatory effectiveness of ferulic acid.

Ferulic acid synthetic is soluble in natural oils up to 0.2 %, warming the oils to 50°C and adding some solubilizers (Ethanol, PEG-40) you can dissolve even 0.5 % Ferulic acid synthetic.
Safety & Health
- Toxicology
The toxicological and pharmacological properties of ferulic acid have been intensively studied - above all in Japan- before approval as an antioxidant agent for food. Neither the oral or the dermal application of ferulic acid caused any significant acute or chronically side effects.
Storage & Handling
- Shelf Life
- 2 years
- Storage Information
GfN Ferulic Acid Synthetic should be stored at tempera- tures below 30°C. The product should not be radi- ated by sunlight or UV-light during hours. In closed containers the storage stability is two years.
