AccessFIX PNE37

Hair Fixative Polymer for Flexible Hold & Humidity Resistance

INCI Name: VP/VA Copolymer

AccessFIX PNE37 is a high-performance film-forming polymer that provides excellent hold and humidity resistance for all types of hair styling products. As a VP/VA Copolymer, it creates a clear, flexible film on the hair that fixes styles in place without stiffness or flaking—ideal for firm-hold gels and hairsprays to light styling creams and mousses.

How to Use AccessFIX PNE37 in Your Formulations

Understanding AccessFIX PNE37

If you want your hair styling products to actually hold a style, you need a film former. AccessFIX PNE37 is a classic, high-performance polymer that does exactly that—think of it as a microscopic net that wraps around each hair strand. When the product dries, this polymer network holds the hair in the shape you styled it, whether that’s a defined curl, a sleek ponytail, or a voluminous blowout.

For the chemists in the room: AccessFIX PNE37 is a copolymer of vinylpyrrolidone (VP) and vinyl acetate (VA). It forms a clear, flexible, non-tacky film upon drying, delivering the fixative effect (hold) essential in styling products. The film also helps shield hair from atmospheric moisture—the main cause of frizz and style collapse—so formulas show excellent humidity resistance. By adjusting usage level, you can dial in anything from light, touchable control to very strong, long-lasting hold.

Formulation Tips

AccessFIX PNE37 is typically supplied as a powder and is water-soluble. Disperse it slowly into the water phase at room temperature with steady mixing (propeller or strong vortex) to avoid clumping (“fish eyes”). Continue mixing until the solution is fully clear—this indicates complete dissolution. No heat is required.

Suggested use levels by desired hold:

Light Hold (Styling Creams, Lotions): 1–3%
Medium Hold (Mousses, Standard Gels): 4–7%
Strong Hold (Firm Gels, Hairsprays): 8–10%

It’s broadly compatible with common styling co-ingredients (thickeners like carbomers and natural gums, conditioning agents, fragrances) and performs across a wide pH window (about 4–9). Incorporation at room temperature is straightforward, making it an easy foundation for gels, sprays, mousses, and creams.

Key Performance Benefits:

Customizable Hold: Adjust concentration to achieve soft, flexible control or extra-firm, long-lasting hold.
Excellent Humidity Resistance: Forms a barrier to atmospheric moisture to help prevent frizz and style collapse.
Crystal-Clear Formulations: Dissolves to a clear solution—ideal for transparent gels and serums.
Non-Tacky Feel: Dries to a clean, flexible film without stickiness.
Versatile & Easy to Use: Works across sprays, gels, mousses, and creams; simple water-phase processing at room temperature.
Minimal Flaking: Flexible film resists cracking and flaking when properly formulated.

Frequently Asked Questions About AccessFIX PNE37

It’s the primary “hold” ingredient in hair styling products. It forms a clear, invisible film on the hair that locks your style in place and helps protect it from humidity, which causes frizz.

Use 1–3% for light, flexible hold (creams/lotions); 4–7% for medium hold (mousses and standard gels); and 8–10% for strong hold (firm gels and finishing sprays).

When used at the correct level for your target hold, AccessFIX PNE37 forms a flexible, non-tacky film that moves with the hair. Properly formulated products resist flaking and avoid the heavy, stiff feel of older gels.

Sprinkle the powder slowly into the water phase under good agitation to prevent clumps (“fish eyes”). Mix until completely clear. No heat is required.

While best known for hair styling, it’s also useful in color cosmetics—for example, in makeup setting sprays to help lock makeup, or in mascaras and brow gels for hold and water resistance.

It’s not a silicone. It’s a synthetic polymer (VP/VA Copolymer) designed as a safe, specialized cosmetic film former—very different from commodity plastics.
