Nkọwa dị mkpirikpi:

PVP (polyvinylpyrrolidone) bụ polymer sịntetik nke na-agbaze mmiri nke ama ama maka njide pụrụ iche, imepụta ihe nkiri, na ihe nkwụsi ike. N'ịbụ nke dị mma biocompatibility na obere toxicity, ọ na-eje ozi dị ka ihe ịchọ mma (ntutu ntutu, shampoos), ihe dị egwu na-emepụta ọgwụ (mbadamba mbadamba, mkpuchi capsule, akwa ọnya), na ngwa mmepụta ihe (inks, ceramics, detergents).
