Abstract
Amine-modified polysiloxanes are applied to the opposite outer surfaces of a tissue product, such as the two outer surfaces of a 3-ply facial tissue, providing improved softness to the surfaces and a degree of hydrophobicity to prevent wet through of liquids during use. However, the degree of hydrophobicity is controlled by the chemical structure of the amine-modified polysiloxane and/or by blending the amine-modified polysiloxane with a more hydrophilic modified polysiloxane such that liquid is still allowed to enter the tissue structure in a reasonably short time to be absorbed by the center ply, but the absorption in combination with the hydrophobicity of the other outer surface substantially delays the liquid from passing completely through the tissue product.
