The role of polyethylene pyrrolidone
Moisturizing effect
Polyethylpyrrolidone has a good moisturizing function, can form a protective film, so that the skin is not easy to lose water. Moreover, it can lock the moisture on the surface of the skin into the skin, so that the moisture content of the skin is effectively increased.
Antioxidant benefits
Polyethylpyrrolidone has a good antioxidant effect, which can neutralize free radicals and prevent skin aging. Among them, free radicals are one of the main causes of skin aging, which can destroy the membrane structure and DNA of skin cells and accelerate skin aging.
Antibacterial effect
Polyvinylpyrrolidone has a good antibacterial effect, which can effectively kill bacteria and viruses on the skin surface, so as to prevent and treat skin infections and other problems.
Anti-pollution and anti-ultraviolet effect
Polyvinylpyrrolidone can play an anti-pollution and anti-UV role, effectively protect the skin from the outside environment. It can form a protective film to block dust and pollution in the air, while absorbing and dispersing ultraviolet rays, effectively preventing sunburn and color spots.
Suggestions For Usage
PVPP can selectively absorb the polyphenols in grape juice and wine and form complexes, which are removed through the filtration process, significantly improving the quality of the wine in terms of color, taste, stability, etc. A relatively low dosage can make the wine stable and clear.
PVPP F can be added during the initial filtration of the juice and the filtration of the finished wine after brewing.
PVPP XL can be added during the wine brewing and aging processes.
