Throughout this process, new bonds are shaped. The molecular force involving a surfactant molecule and a h2o molecule is lessen than the pressure amongst two h2o molecules. This minimizes floor tension and allows for deep penetration and improved effectiveness in product formulations.
Cationic dyes show substantial washfastness, producing them suitable for purposes wherever the dyed merchandise will endure Recurrent washing or exposure to drinking water.
