RHEOLYX

Clarity, without compromise.

RHEOLYX U-21

High-clarity, self-wetting, salt-tolerant — roughly 15% less polymer for the same viscosity.

Overview

RHEOLYX U-21 combines the clarity expected of a premium gel polymer with self-wetting dispersion and useful electrolyte tolerance.

In side-by-side trials it reaches 9-series viscosity at approximately 15% lower dose, wetting out in around three minutes without prolonged shear.

This is the grade for hydroalcoholic sanitiser gels, high-clarity serums, and any system where both optics and salt load are constrained.
