Abstract
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.
Claims19
A softened tissue paper having on at least one surface thereof a tri-component biodegradable softener composition mixture comprising:
- (a) a nonionic softener selected from the group consisting of sorbitan mono-, di-, tri- esters and mixtures thereof;
- (b) a nonionic surfactant compatibilizer selected from the group consisting of ethoxylated sorbitan esters, propoxylated sorbitan esters, alkylpolyglycosides and mixtures thereof;
- and
- (c) a polyhydoxy compound selected from the group consisting of glycerol, polyethylene glycol, polypropylene glycol and mixtures thereof;
- wherein the weight ratio of the nonionic softener to the nonionic surfactant compatibilizer ranges from about 10:1 to 1:10 and wherein the weight ratio of the nonionic softener to the polyhydroxy compound ranges from about 10:1 to 1:10, the tri-component softener being present in an amount from about 0.1% to about 3% by weight of the dry tissue paper.
