Published by American Chemical Society. 2-in-1 laundry formulations have become popular among consumers as these represent a great alternative to standard detergents offering both cleaning and softening benefits in one product. Deposition aid polymers are crucial additives of a 2-in-1 formulation as they enhance the deposition of softness active ingredients. In this work, a novel class of pullulan derivatives grafted with cationic moieties (CatPs) have been synthesized and their softness and cleaning performance in a 2-in-1 laundry detergent have been assessed. Results show that the addition of cationic appendages is indispensable to observing an increase in textile softness. Compared with similar cationic polysaccharides, CatPs were also able to deliver better antiredeposition performance on both cotton-based and synthetic garments, probably on account of their higher capacity to stabilize particulate soil suspensions. The investigation of the solution behavior of CatPs with a typical laundry formulation revealed a phase separation (coacervation) occurring as a result of the association of the cationic pullulans with anionic surfactants. Results highlighted the dependence of this phenomenon on the polymer concentration and composition. This work demonstrates that CatPs represent a promising biorenewable additive for laundry detergent, providing both effective softness and cleaning performance.
