Chinese gallnut extract is a natural product derived from Chinese gallnuts (insect galls). Its primary constituent is hydrolyzable tannin (tannic acid), with a content ranging from 50% to 70%. It exhibits strong astringent, antioxidant, finding widespread application in both the personal care industry and industrial sectors.
Sources and Composition:
Chinese gallnuts are not the fruit of a plant; rather, they are sac-like galls formed when the leaves of plants such as the Chinese sumac (*Rhus chinensis*) are parasitized and stimulated by insects like the Chinese gall aphid.
The extract's primary active ingredient is Chinese gallnut tannin—specifically gallotannin—which yields gallic acid upon hydrolysis.
It also contains minor amounts of compounds such as methyl gallate and flavonoids; these collectively contribute to its astringent and anti-inflammatory properties.
Application
Personal Care and Skincare: Added to shampoos and skincare products, it helps improve oily skin and dandruff conditions by leveraging its oil-controlling, pore-tightening, and antibacterial properties.
Industrial Applications: It serves as a natural tanning agent and dye fixative, and acts as a raw material for anti-corrosion coatings on metal surfaces.

For some products that require special packaging during transportation, we will carry out more delicate packaging. For example, retinal needs to be stored at -20 °C, so we choose cold chain transportation during transportation; deoxyarbutin will change color during transportation, so we will Vacuum packing of deoxyarbutin
