    13. Alkali Swellable Emulsion - Viscosity vs. pH

    15. Benefit of Associative Polymers

    17. Applications for Anionic RHEOVIS Polymers Associative polymers recommended in formulations having: high level of electrolyte (e.g. anionic surfactants) and/or high pH => RHEOVIS ATA & RHEOVIS ATX Non-associative polymer recommended in formulations having: - low level of electrolyte and/or neutral pH => RHEOVIS ATN To find the most suitable polymer it is recommended to test all three anionic polymers RHEOVIS ATA, ATX and ATN for a specific detergent formulation.

    18. Incorporation of Anionic RHEOVIS Polymers Post-addition is the easier way Good stirring required (100-200 rpm / avoid high shear rates) Pre-dilution required only if pH of the solution > 12 Adjust the pH of the formulation after addition of the polymer Incorporation levels: 0.5% to 5% polymer as supplied

    28. RHEOVIS CDP & CDE – Practical advices Pre- and post-addition possible Homogenize/stir the polymer dispersion before use Incorporate slowly the polymer under stirring Thickening performance depends on the formulation Suited for batch and continuous production processes Avoid high shear rates

    30. Beads Polymer

    31. Incorporation levels of Cationic RHEOVIS Polymers Rinse Conditioners 0.1 to 0.5% polymer as supplied Acid Cleaners 0.5 to 5.0% polymer as supplied

    32. RHEOVIS CSP – Practical advices Pre- and post-addition possible in acid cleaners Pre-addition in softener formulations - after the cationic surfactant Avoid high shear rates Pre-mixing in surfactant improves polymer‘s solubility Spread / Incorporate slowly the polymer under stirring 1- Add polymer to the vortex of the formulation, vigorously stirred. 2- Wet the polymer with a water-miscible solvent (ethanol) before addition into water (recommended in Lab. tests) 3- Use an Eductor
