This study explores how different dispersants influence the quality and stability of aqueous titanium dioxide dispersions. Comparing a market‑standard polyacrylate with Lankem’s Lansperse SPA and DS80, results show significant improvements in particle size, viscosity control, and storage stability—especially with the high‑performing Lansperse DS80.

This work has highlighted that the biobased range of products are suitable as dispersing agents for Pigment Red 101 red iron oxides.
