藥典名稱(chēng)：交聯(lián)聚維酮、Crospovidonum（USP）、Crospovidone(EP)
Pharmacopoeia name: Crospovidone, Crospovidonum (USP), Crospovidone (EP)
化學(xué)名稱(chēng)：交聯(lián)聚乙烯基吡咯烷酮
Chemical name: Cross-linked polyvinyl pyrrolidone
INCI/CTFA：Insoluble PVP
CAS號：9003-39-8、25249-54-1
主要性質(zhì)：本品具有高度的毛細管/水含容量，比表面大，水合能力極強，吸水作用高而迅速，吸水膨脹能力強，具有聚乙烯吡咯烷酮相同的絡(luò )合能力，能絡(luò )合多種物質(zhì)，如酚類(lèi)、碘等。20KG/紙板桶，遮光、密封，在陰涼干燥處保存。
Main properties: This product has a high capillary/water content, large specific surface area, extremely strong hydration ability, high and rapid water absorption, strong water absorption and swelling ability, and has the same complexing ability as polyvinyl pyrrolidone, and can complex with a variety of substances, such as phenols, iodine, etc. 20KG/cardboard barrel, light-proof, sealed, stored in a cool and dry place.
應用性能
PVPP產(chǎn)品為不溶性高分子交聯(lián)聚合物，具備獨特的網(wǎng)狀性能結構，彌補了由于PVP優(yōu)異的溶解性在某些方面反而被限制了的應用缺陷。且PVPP不溶于酸、堿及一般有機溶劑，而PVP則相反。 PVPP具有良好的生理安全性、吸水性、水不溶性、絡(luò )合性等優(yōu)良特性，在醫藥、食品、日用化工、飼料等領(lǐng)域有廣闊的應用前景。
Application performance
PVPP products are insoluble high molecular cross-linked polymers with unique network performance structure, which makes up for the application defects that are limited in some aspects due to the excellent solubility of PVP. And PVPP is insoluble in acid, alkali and general organic solvents, while PVP is the opposite. PVPP has good physiological safety, water absorption, water insolubility, complexation and other excellent properties, and has broad application prospects in the fields of medicine, food, daily chemical industry, feed, etc.
生物醫藥領(lǐng)域：PVPP具有良好的生理惰性和生物相容性，以及良好的綜合性能。 PVPP可用于藥物崩解劑、藥物緩釋載體以及血液透析膜等。由于交聯(lián)PVPP吸水膨脹而使片劑（膠囊）內造成很高的壓力，迅速崩解成無(wú)數小顆粒，提高人體生物利用度。以各種高分子生物材料為基質(zhì)的藥物控制釋放系統，提高了藥物作用的持續性和專(zhuān)一性。PVPP具有良好的吸收液體的能力，能透過(guò)空氣屏蔽細菌，可以吸收并釋放藥物，因此也可以作外傷包扎帶使用。
Biomedicine field: PVPP has good physiological inertness and biocompatibility, as well as good comprehensive performance. PVPP can be used for drug disintegrants, drug sustained-release carriers and hemodialysis membranes. Due to the water absorption and expansion of cross-linked PVPP, a high pressure is created in the tablet (capsule), which quickly disintegrates into countless small particles, improving the bioavailability of the human body. The drug controlled release system based on various polymer biomaterials improves the continuity and specificity of the drug effect. PVPP has a good ability to absorb liquids, can shield bacteria through the air, can absorb and release drugs, so it can also be used as a wound dressing.
釀造和飲料工業(yè)領(lǐng)域：PVPP具有較強的選擇吸附能力，能有效地除去植物性飲料中的花色苷和多酚，從而除去植物性飲料的非生物沉淀，保持口感和原風(fēng)味，提高清晰度，改善色澤，延長(cháng)保持期，因此就用于啤酒、果汁、飲料、葡萄酒等行業(yè)。
Brewing and beverage industry: PVPP has strong selective adsorption ability and can effectively remove anthocyanins and polyphenols in plant-based beverages, thereby removing non-biological precipitation in plant-based beverages, maintaining taste and original flavor, improving clarity, improving color, and extending shelf life. Therefore, it is used in beer, juice, beverage, wine and other industries.
