（5）Preparation of stable vitamin preparations
Yog‘da yuqori darajada eriydigan vitaminlar-(A, D, E) vodorodlangan yog‘lar yoki mumlardagi qattiq eritmalar shaklida tayyorlanishi, so‘ngra tarkibida jel bo‘shlig‘iga-plastikizatorda juda mayda boncuklar shaklida tarqatilishi mumkin. Bunday mahsulotlar nisbatan yuqori haroratli havoga uzoq vaqt ta'sir qilgandan keyin ham ancha barqaror{2}}bo'ladi.
(6) Og'izdan suyuqlik preparatlarida stabilizator sifatida ishlatiladi
PVP K-90 og'zaki suyuqlik dozalash shakllarida keng qo'llanilishiga ega. bir hil va barqaror mahsulot olish uchun foydalanish mumkin.
(7) Oftalmologiya va boshqa farmatsevtika sohalarida qo'llanilishi
①1 percent 2 percent concentration of K90 can be used to relieve eye irritation; ②It can enhance the effect of contact lens cleaning solution; ③Compared with HPMC, methylcellulose or polyvinyl alcohol when benzalkonium chloride is used in the prescription, there are few compatibility problems; ④ the adhesion damage of the peeled-in contact lenses is extremely low; ⑤ compared with other polymers, it has the highest biocompatibility for 0.1 percent tropicamide; For artificial tears, it is better than polyvinyl alcohol; ⑦ It can be used as a pore-forming agent for the controlled release layer in long-acting eye masks.

PVP juda barqaror kislotali jelleşme agenti bo'lib, tuz konsentratsiyasiga sezgir va ayniqsa, suvli loy hududlarida yuqori tuz konsentratsiyasiga ega polimer toshqinida foydalidir. PVP va boshqa organik moddalar suv eritmasi bilan aralashtiriladi va neft qudug'iga AOK qilinadi, bu neft konining neftni qayta ishlash tezligini oshirishi mumkin. Tadqiqotning chuqurlashishi bilan PVPning kelajakdagi rivojlanishi yangi dastur maydonlarini ochadi.
