Abstract
A process for making tissue papers, in particular pattern densified tissue papers, having an enhanced tactile sense of softness when treated with tri-component biodegradable softener compositions are disclosed. These tri-component softener compositions comprise nonionic softeners, nonionic surfactant compatibilizers and polyhydroxy compounds. The weight ratio of the nonionic softeners to the nonionic surfactant compatibilizers ranges typically from about 10:1 to 1:10. The weight ratio of the nonionic softeners to the polyhydroxy compounds ranges typically from about 10:1 to 1:10. The tri-component biodegradable softeners are typically applied from an aqueous dispersion to at least one surface of the dry tissue paper web.
