| use | Flavors and fragrances |
| It can be used as an aromatic mixture in soap, shampoo, washing powder and daily cosmetics. | |
| Cinnamic acid modulates apples and cherries, and can be used as apple flavor, cherry flavor, fruit flavor, and floral flavor. | |
| Food additives | |
| Cinnamic acid is synthesized by microbial enzymatic method to L-phenylalanine. L-Phenylalanine is an important food additive-the main raw material of sweet aspartame (Aspartame). | |
| The anti-mildew, antiseptic and sterilization using cinnamic acid can be applied to the preservation and antiseptic of grain, vegetables and fruits. | |
| Pharmaceutical industry | |
| In the pharmaceutical industry, it can be used to synthesize the important drugs for the treatment of coronary heart disease, lactic acid, Xintongping and Xintongping, and to synthesize meclofenac and cinnamon piperazine to make "Xinkean", local anesthetics, fungicides, and hemostasis Medicine etc. It can also be used to synthesize meclofenac and cinnamon piperazine, which can be used as a spinal bone relaxant and antispasmodic agent. Mainly used for cerebral thrombosis, cerebral arteriosclerosis, coronary arteriosclerosis and other diseases. It has a significant inhibitory effect on the proliferation of lung adenocarcinoma cells. Cinnamic acid is an effective inhibitor of A-5491 human lung adenocarcinoma cells and has great application value in anti-cancer. | |
| Beauty | |
| Cinnamic acid can be used in cosmetics. Tyrosinase is the key enzyme for melanin synthesis. It initiates the cascade reaction that converts tyrosine into melanin biopolymers. Cinnamic acid has the effect of inhibiting the formation of tyrosinase and has certain effects on ultraviolet rays. The insulative effect can make brown spots lighten or even disappear. It is one of the essential ingredients in advanced sunscreens. The significant antioxidant effect of cinnamic acid has a good effect on slowing down the appearance of wrinkles. Cinnamic acid also has a good fragrance-preserving effect. It is usually used as a flavoring raw material and used as a fixative in daily chemical flavors. | |
| Remarks | According to customer needs, products with various purity and other indicators can be produced. |
