Usage And Synthesis
Physical and Chemical Properties

Caffeic acid, scientific name: "3-(3,4-dihydroxyphenyl)-2-propenoic acid." Molecular formula: C9H8O4; the molecular weight: 180.16. It is presented in plants such as coffee in the form of chlorogenic acid. It is yellow crystals with melting point being 223~225 °C. When it is precipitated in concentrated solution, it contains no crystal water. However, precipitate of crystals from dilute solution contains one molecule of crystallized water. It is slightly soluble in water, and easily soluble in hot water, cold ethanol, and ethyl acetatee. Its alkaline solution is orange and exhibits dark green when being mixed with ferric chloridee.
Application: caffeic acid is safe to be applied in cosmetics and has a broader antibacterial and antiviral activity. It can also absorb ultraviolet radiation. A low concentration of it already has inhibitory efficacy on the generation of skin melanin. Its applied amount in the beauty products for whitening is at the range of 0.5 to 2%. It can also be used as additive for the oxidized hair dyes which is good for enhancing the strength of the color.
