Inquiry on PVPP (Cross-linked PVP) Grade
Question
I saw on the website that Polyvinylpolypyrrolidone (PVPP, Cross-linked PVP) is commonly used as a tablet disintegrator. The description states "Cosmetic Grade / Food Grade BEFORE REPACK" and "ONLY Cosmetic Grade AFTER REPACK". I would like to know if the grade sold by the store is Cosmetic Grade or Food Grade.
Answer
Product Grade Information
Based on the available product information, I could not find a product specifically named "Polyvinylpolypyrrolidone (PVPP, Cross-linked PVP)". The search results included various types of Polyvinylpyrrolidone (PVP) with different K-values, but not the cross-linked version you inquired about.
Therefore, I cannot confirm the grade (Cosmetic Grade or Food Grade) for the specific "Polyvinylpolypyrrolidone (PVPP, Cross-linked PVP)" product you mentioned from the website information.
