Polyvinylpyrrolidone PVP K90

Introduction to PVP K90 and PVP K30 (Chemical Name: Polyvinylpyrrolidone or PVP for short):

CAS NO: 9003-39-8. PVP K30 is typically a white powder with an average molecular weight of about 40,000, while PVP K90 has a molecular weight of approximately 1.3 million. It is a non-ionic polymer synthesized from the monomer N-vinylpyrrolidone (NVP), easily soluble in water, alcohol, and other solvents, forming a slightly yellow to colorless liquid. It is non-toxic, odorless, and non-irritating.

It can be used as a pharmaceutical excipient binder, leveling agent, scouring agent, and anti-staining agent in textile printing and dyeing, as a film-forming agent and thickener in cosmetics, and as a dispersing stabilizer in inks. It is one of the commonly used chemical auxiliaries. With further advancements in science and technology, the application fields of PVP are becoming increasingly broad, and it has been utilized in industries such as construction materials, electroplating, and fibers.

Applications in the Textile Printing and Dyeing Industry:

The binding capacity of PVP K30 varies with different dyes. Utilizing this property, PVP can be used as a local anti-dyeing agent to produce printed fabrics with clear patterns and sharp outlines. Scouring agents for the printing and dyeing industry, primarily composed of PVP and sodium aluminosilicate, exhibit significantly higher scouring efficiency compared to those without PVP. They also prevent color transfer or staining of white backgrounds during the scouring process.

Applications in the Cosmetics and Daily Chemical Industry:

PVP K30 and PVP K90 are non-toxic and non-irritating in skincare, haircare products (such as mousse, gel, hair wax, toothpaste), and serve functions such as film-forming, binding, moisturizing, and dispersing. They are widely used due to their excellent surface activity.

Applications in Pharmaceuticals:

PVP K30 (Polyvinylpyrrolidone K30) is commonly used as a binder for tablets and granules in the pharmaceutical industry. Tablets made with K30 as a binder are less prone to cracking. The typical addition amount is 0.5-5%, making it one of the most commonly used excipients.

Applications in the Ink Industry:

PVP K30 acts as a dispersant in inks, ensuring uniform and stable ink systems, preventing nozzle clogging, and enabling good adhesion of printed text to paper without fading.

In other industries, Polyvinylpyrrolidone (PVP) is also widely used in:

As a dispersant and thickener in coatings, paints, and inks.

As a seed coating agent in agriculture for the surface treatment of crop or other plant seeds.

As a thickener, lubricant, dispersant for printer ribbons, inks, graphite, and as a raw material for solid glue, adhesives, papermaking, etc., in office supplies.

As a pore-forming agent for water treatment membranes (hollow fiber ultrafiltration membranes, sulfone, polysulfone) in the water treatment industry.

Glass fiber industry.

Electronic battery industry.

Leather industry, among others.

Product quality complies with industrial grade/USP26/CP2020/EP and other pharmacopoeia standards.
