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.

Following a laboratory study by Lankem into the performance of bio-based dispersants in aqueous dispersions of titanium dioxide pigment, two products were shown to give excellent performance in comparison to a conventional sodium polyacrylate dispersant.

Lansperse BIO868 performs very well as a bio-based dispersant for Pigment Violet 23 in water-based systems. It consistently produced low-viscosity millbases, remained stable during storage, and achieved strong colour development with fewer milling passes than the market standard.

Lankem can now offer more eco-friendly, label-free dispersing agents based on our new BioLoop technology.
