Abstract
The present disclosure describes methods of treating cellulosic materials with compositions that allow greater retention of inorganic particles on cellulosic substrates. The methods as disclosed provide combining saccharide fatty acid esters (SFAE) with such inorganic particles and applying such combinations on cellulosic materials to eliminate or reduce the use of retention aids or binders for filler in the paper making process. Compositions comprising such combinations of SFAE and inorganic particles are also disclosed.
