PVP K30, also called povidone K30, is a water-soluble grade of polyvinylpyrrolidone (CAS 9003-39-8). In tablet manufacturing, it helps bind powder particles into granules. In hair styling, it forms a film as the product dries. The grade, solvent system and finished-product requirements determine how it performs in each formulation.
PVP K30 as a Tablet Binder
In wet granulation, an aqueous povidone solution wets the powder blend and helps particles adhere. The binder remains in the dried granules, which can then be compressed into tablets. BASF technical data for pharmaceutical povidone describes this use in solid oral dosage forms.
Evaluate binder performance in the intended tablet formulation. Granule size and fines are useful checks before compression. Tablet strength, disintegration and dissolution help show whether the binder level fits the finished dosage form.
PVP K30 as a Hair Styling Film Former
As a styling gel, mousse or pump spray dries, PVP K30 leaves a film on the hair that helps hold the style. It dissolves in water and ethanol, which gives formulators options for water-based and hydroalcoholic products. BASF technical data for cosmetic PVP K30 lists these hair styling formats.
For a pump spray, evaluate solution clarity and spray pattern together with the hold and feel of the dry film. A gel needs its own checks for texture, hold and how the film behaves at the expected humidity.
PVP K30 in Textile Printing Inks and Membranes
A study of disperse dye inks for textile printing evaluated PVP K30 as a water-soluble polymer additive. A separate polyethersulfone ultrafiltration membrane study used K30 and K15 together as pore formers. These examples depend on the ink or membrane formulation and its processing conditions.
PVP K30 and PVPP in Beverage Processing
PVP K30 is soluble. Polyvinylpolypyrrolidone (PVPP) is crosslinked and insoluble. The OIV practice for PVPP treatment of wine identifies PVPP as the processing aid used to reduce tannins and other polyphenols.
What to Check When Selecting a PVP K30 Grade
The K-value is calculated from solution viscosity and relates to the polymer’s average molecular weight. The Unilong PVP K30 specification lists a K-value range of 27–32.4. Compare the K-value method, water content and relevant impurity limits on the grade specification and the batch certificate of analysis. For pharmaceutical or food applications, confirm the required grade documentation for the intended use and market.
