Generic name: VP/VA Copolymer

INCI Name: VP/VA COPOLYMER

Monomer ratio: VP : VA = 70 : 30

* PVP/VA Copolymer (Copovidone) Mainstream Model Description

Basic Physical Properties

Form and Specification

Dissolution properties: Highly soluble in cold/hot water, ethanol, and isopropanol; insoluble in alkanes, mineral oil, and ether; hydrophilicity is higher than VA64 and VA37

K value (1% ethanol solution): 28 ~ 38

The aqueous solution exhibits weak acidity and is composed of non-ionic polymers, demonstrating excellent compatibility with various cosmetic raw materials such as anionic and cationic substances, carbomers, and more

Core Features (Comparison with VA64/VA37)

- The VP content is higher, with stronger hydrophilicity and easier film formation for water washing removal

- The film is soft, with a natural luster and minimal stiffness

- The moisture resistance is weaker than VA37; suitable for permanent formulations requiring low humidity and high water-washing performance

- The solution has excellent transparency and is suitable for an alcohol-free water-based hair care system

Main Applications (Primarily for Cosmetic Grade, Non-Pharmaceutical Polyvinylpyrrolidone)

- Hair styling raw materials (most mainstream)

- Water-based hair gel, pump spray styling water, hair wax, mousse, and wet hair styling gel; particularly suitable for alcohol-free formulations, easy to rinse, and less prone to leaving white residue.

- Skincare: Facial Mask Forming Aid, Pull-up Facial Mask Carrier

- Industrial field: Resin for wet adhesives, water-based coatings, and ink film-forming resins

Note: VP/VA73 is not used as a pharmaceutical copovidone; VP/VA64 is the preferred excipient for pharmaceutical applications.

Storage and Packaging

Packaging: 25kg cardboard drum (lined with PE bag); liquid is in 200kg plastic drums
