AccessFIX PAU-50

Hair Fixative Polymer for Strong, Humidity-Resistant Hold

INCI Name: AMP-Acrylates Copolymer

AccessFIX PAU-50 is a high-performance hair fixative polymer that provides the essential structure and hold for modern styling products. As a film-former, it creates a clear, non-tacky coating on the hair shaft to lock styles in place, even in high humidity. It is exceptionally versatile, enabling formulators to create everything from firm-hold styling gels and mousses to lightweight pump sprays with excellent performance and clarity.

How to Use AccessFIX PAU-50 in Your Formulations

Understanding AccessFIX PAU-50

AccessFIX PAU-50 is a hair fixative polymer (film-former) — the key ingredient that provides hold in gels, mousses, and sprays. As your product dries, the polymer forms a clear, flexible film on the hair fiber, connecting strands and locking styles in place without a tacky residue.

For the chemistry-minded, AccessFIX PAU-50 is an anionic polymer dispersion. In its raw state, polymer chains are coiled. When you neutralize the dispersion with a base, the chains uncoil, viscosity builds, clarity improves, and the polymer is “activated” to form a strong, continuous film upon drying. This activation step is what delivers high hold and excellent humidity resistance.

Formulation Tips

Use 2–10% depending on desired performance. For light-to-medium hold sprays, use 2–5%. For firm/strong-hold gels or edge control formats, use 6–10%.

Neutralization is the critical step for performance and clarity. General process:

1. Disperse AccessFIX PAU-50 into the water phase with good mixing (initial mix will be thin and acidic).

2. Slowly add a neutralizer while mixing — common choices include Aminomethyl Propanol (AMP), Triethanolamine (TEA), or sodium hydroxide.

3. As pH rises, viscosity and clarity develop. Target a final pH of 7.0–8.0 for optimal hold, film formation, and humidity resistance.

Compatibility: AccessFIX PAU-50 works well with many styling additives and plasticizers; add these after neutralization when possible. Because it is anionic, avoid high levels of cationic materials that can cause instability or haze.

Key Performance Benefits

Strong, Long-Lasting Hold: Provides durable style retention that lasts all day.

Frequently Asked Questions About AccessFIX PAU-50

It’s the main ingredient that provides hold. It forms a thin, invisible film on the hair to keep strands in place—great for curls, spikes, or sleek looks.

Use 2–5% for lighter, more flexible hold (sprays, mousses). For very strong, firm hold (sculpting gels, edge control), use 6–10%.

This polymer is acidic in its raw state and won’t perform until you raise the pH with a base. Neutralization uncoils the polymer, builds viscosity, and enables strong film formation for hold and humidity resistance.

Typical neutralizers include Aminomethyl Propanol (AMP), Triethanolamine (TEA), or sodium hydroxide. Add gradually with mixing and target a final pH of 7.0–8.0.

At higher use levels it provides firm hold, but when properly neutralized it dries non-tacky. Add plasticizers or conditioning agents to increase flexibility and softness if desired.

Yes. Its excellent humidity resistance helps define curls and control frizz, preventing expansion and droop in damp conditions.

Absolutely. When properly neutralized, AccessFIX PAU-50 yields crystal-clear gels for a professional appearance.
