PVP K90, also known as Polyvinylpyrrolidone K90 or Povidone PVP K90, is a high molecular weight polymer widely used in personal care, cosmetic, pharmaceutical, and industrial formulations. Compared with lower grades like K30 or K60, PVP K90 offers stronger film-forming ability, higher viscosity, and better adhesion performance.

As a non-ionic, water-soluble polymer, it is compatible with a wide range of surfactants, resins, and active ingredients—making it an indispensable additive in many formulations.

I. Key Properties and Solubility of PVP K90

One of the most important advantages of PVP K90 is its excellent solubility in water and alcohols.

• PVP K90 solubility: Readily soluble in water, ethanol, and isopropanol.
• Appearance: White to off-white powder.
• Viscosity: High viscosity grade (2.4–3.0 mPa·s, 5% solution).
• CAS Number: 9003-39-8.

Its strong binding capability and clear aqueous solution make it ideal for both liquid and gel-based cosmetic formulations.

II. PVP K90 in Hair Care Products

In the hair care industry, PVP K90 plays a crucial role in improving the performance and feel of products such as:

1. Hair Styling Gels and Sprays

PVP K90 forms a flexible, transparent film that provides long-lasting hold without flaking. It allows hair to maintain shape while still feeling soft and natural.

2. Shampoos and Conditioners

In shampoos and conditioners, PVP K90 enhances foam stability, improves viscosity, and supports conditioning agents for smoother, shinier hair.

3. Hair Mousse and Setting Lotions

Its excellent film-forming and moisture retention abilities help maintain style definition and volume, especially under humid conditions.

4. Color Protection and Repair Formulas

When combined with silicones or proteins, polyvinylpyrrolidone K90 helps form a protective layer that prevents color fading and reduces hair damage from environmental stress.

III. PVP K90 in Skincare and Cosmetic Applications

PVP K90 is equally valued in skincare and cosmetic formulations due to its non-toxic, non-irritating, and film-forming characteristics.

1. Facial Masks and Lotions

PVP K90 improves spreadability and helps retain moisture on the skin’s surface, enhancing comfort and product performance.

2. Sunscreens and Foundations

It stabilizes emulsions and provides excellent dispersion of UV filters and pigments, leading to more uniform coverage and smoother texture.

3. Makeup Products

In mascaras, eyeliners, and lipsticks, PVP K90 increases adhesion and lasting power, ensuring a clean, smudge-free finish.

4. Serums and Gels

Due to its high viscosity and water solubility, PVP K90 powder is perfect for clear gel systems and lightweight serums that require transparency and smooth texture.
