It is a natural phenolic compound, mainly derived from various plants such as lemon peel, Ranunculaceae plant roots, andValeriana officinalis.
The usage of caffeic acid in whitening beauty products is 0.5-2%.
Caffeic Acid is a natural phenolic compound initially found in plants.
As a natural Antioxidant and antibacterial ingredient, it is commonly used for pharmaceutical, cosmetic, dermatological and aesthetic applications.
Caffeic Acid is multifunctional. It has antioxidant and brightening functions, which can be used as a preservative in cosmetic products.
The mechanism of brightening function of caffeic acid is primarily based on the following two facts:
1. The chemical structure of caffeic acid is very similar to L-tyrosine.
Therefore, caffeic acid can be degraded by tyrosinase to become a competitive inhibitor against melanin.
2. Caffeic acid can inhibit melanin production by inhibiting the signal path between tyrosinase and MITF (microphthalmia-associated transcription factor).
Effects:
① Inhibition of fibrosarcoma cancer cell proliferation
② In vivo and in vitro antioxidative effects
③ Immunomodulation
④ Anti-inflammatory activity
⑤ Neurodepressant; promoting sleep and reducing anxiety
Applications:
① Caffeic acid tablet
② Cosmetic ingredient (sun-protective, antibacterial, whitening)
③ Hemostatic drug for hemorrhagic diseases
④ Cough relief and phlegm clearing
Antioxidant:
Caffeic Acid has extraordinary capablity of scavenging free radicals.
In DPPH and ABTS experiments it prevails other phenolic acid compounds and cinnamic acid derivatives.
Antibacterial:
Caffeic Acid shows great abiity in inhibiting growth of mirobes especially Afiatoxin.
