Abstract

Tissue papers, in particular pattern densified tissue papers, having an enhanced tactile sense of softness when treated with certain nonionic softeners are disclosed. These nonionic softeners are biodegradable and comprise sorbitan esters, ethoxylated/propoxylated versions of these sorbitan esters, or mixtures thereof. The softener is typically applied from an aqueous dispersion or solution thereof to at least one surface of the dry tissue paper web.
