Product Description

YIGYOOLY Polyvinylpyrrolidone, largely wholesaled from China, is a non-ionic polymer compound, which is the most distinctive and extensively studied fine chemical among N-vinylamide polymers. It has developed into a series of homopolymers, copolymers, and cross-linked polymers with three major categories: non-ionic, cationic, and anionic, and three specifications: industrial grade, pharmaceutical grade, and food grade. Its relative molecular weight ranges from thousands to over one million, and it has been widely used due to its excellent and unique properties.

YIGYOOLY Polyvinylpyrrolidone, as a synthetic water-soluble polymer compound, has the general properties of water-soluble polymer compounds, including colloid protection, film-forming, bonding, moisture absorption, solubilization or coagulation. However, its most distinctive feature is its excellent solubility and physiological compatibility, which have attracted attention. In the synthesis of polymers, PVP, which is soluble in both water and most organic solvents, has low toxicity, and good physiological compatibility, is not commonly seen, especially in fields closely related to human health such as medicine, food, and cosmetics. The following is an introduction to its application areas.

YIGYOOLY Polyvinylpyrrolidone application in the field of medicine and health:

PVP has excellent physiological inertness, does not participate in human metabolism, and has excellent biocompatibility, which does not cause any irritation to the skin, mucosa, eyes, etc. Medical grade PVP is one of the three major new pharmaceutical excipients advocated internationally, which can be used as a binder for tablets and granules, a co solvent for injections, and a flow aid for capsules; Detoxifiers, extenders, lubricants and film-forming agents for eye drops, dispersants for liquid formulations, stabilizers for enzymes and thermosensitive drugs, and can also be used as low-temperature preservatives. Used for contact lenses to increase their hydrophilicity and lubricity. PVP itself is not carcinogenic and has good food safety. It can form complexes with specific polyphenolic compounds (such as tannins) and is mainly used as a clarifying and stabilizing agent in food processing, such as beer, fruit juice, and wine.

YIGYOOLY Polyvinylpyrrolidone application in the field of daily: Due to its extremely low toxicity and physiological inertness, PVP is non irritating to the skin and eyes, and has a record of long-term use in the pharmaceutical field, making it very safe for use in cosmetics and other products. In daily cosmetics, PVP and copolymer have good dispersibility and film-forming property. PVP can protect colloid in lotion, and can be used in fat and non fat creams, as setting liquid, hair spray and mousse setting agent, hair conditioner sunscreen, shampoo foam stabilizer, wave setting agent, and hair dye dispersant and affinity agent. Adding PVP to snow cream, sunscreen, and hair removal agents can enhance wetting and lubrication effects.

YIGYOOLY Polyvinylpyrrolidone application in the field of detergents: PVP has anti fouling and re precipitation properties and can be used to prepare transparent liquids or heavy fouling detergents. Adding PVP to detergents has a good anti discoloration effect and can enhance cleaning ability. When washing fabrics, it can prevent synthetic detergents from irritating the skin, especially synthetic fibers. This performance is more outstanding than carboxymethyl cellulose (CMC) detergents. PVP can be compounded with borax as an effective ingredient in the formulation of phenolic disinfectant cleaning agents. The detergent composed of PVP and hydrogen peroxide has the functions of bleaching and killing bacteria.

YIGYOOLY Polyvinylpyrrolidone application in the field of the textile printing and dyeing field: PVP has good affinity with many organic dyes and can combine with hydrophobic synthetic fibers such as polyacrylonitrile, esters, nylon, and fibrous materials to improve dyeing power and hydrophilicity. Kirsh Y E et al. reported that the fabric produced by PVP and nylon graft copolymerization improved its moisture resistance and moisture resistance.

YIGYOOLY Polyvinylpyrrolidone application in the field of coatings and pigments: Paints and coatings coated with PVP are transparent without affecting their natural color, improving the gloss and dispersibility of coatings and pigments, enhancing thermal stability, and improving the dispersibility of inks and inks.

YIGYOOLY Polyvinylpyrrolidone application in the field of polymer surfactants: Polyvinylpyrrolidone, as a polymer surfactant, can be used as a dispersant, emulsifier, thickener, leveling agent, particle size regulator, anti re precipitation agent, coagulant, cosolvent, and detergent in different dispersion systems.

YIGYOOLY Polyvinylpyrrolidone application in other fields:PVP can serve as a gelling agent for tertiary oil recovery, improving the oil recovery rate of the oilfield. As an additive for photosensitive materials, it helps to reduce latex content and enhance the coverage ability of developing images. As a thickener, dispersion stabilizer, and bonding regulator in the process of polymer polymerization. As a dispersant in the papermaking industry and as a co catalyst in the propylene amine gasification reaction. The application of PVP in fields such as separation membranes, photocurable resins, laser discs, drag reducing coatings, building materials, steelmaking, and electroplating is also on the rise.

Storage & Note

YIGYOOLY Polyvinylpyrrolidone shall be stored in a cool and ventilated warehouse. Stay away from sparks and heat sources. Packaging sealing. It should be stored separately from oxidants, aluminum, and edible chemicals, and should not be stored together
