Abstract

A softening composition, particularly useful for topical treatment of tissues, comprises a polysiloxane, a fatty alkyl derivative and glycerin. The softening composition provides good softness to the tissue and enables the tissue to retain a high degree of absorbency.

Claims

exact text as granted — not AI-modified
1 . A tissue softening composition comprising, based on the total amount of actives in the composition, from about 5 to about 40 weight percent polysiloxane, from about 10 to about 50 weight percent of an fatty alkyl derivative, from about 20 to about 80 weight percent glycerin. 
     
     
         2 . The composition of  claim 1  wherein the amount of polysiloxane is from about 5 to about 30 weight percent. 
     
     
         3 . The composition of  claim 1  wherein the amount of polysiloxane is from about 5 to about 20 weight percent. 
     
     
         4 . The composition of  claim 1  wherein the amount of fatty alkyl derivative is from about 20 to about 50 weight percent. 
     
     
         5 . The composition of  claim 1  wherein the amount of fatty alkyl derivative is from about 30 to about 50 weight percent. 
     
     
         6 . The composition of  claim 1  wherein the amount of glycerin is from about 25 to about 80 weight percent. 
     
     
         7 . The composition of  claim 1  wherein the amount of glycerin is from about 30 to about 80 weight percent. 
     
     
         8 . The composition of  claim 1  wherein the amount of glycerin is from about 30 to about 70 weight percent. 
     
     
         9 . The composition of  claim 1  wherein the amount of polysiloxane is from about 5 to about 20 weight percent, the amount of fatty alkyl derivative is from about 20 to about 50 weight percent and the amount of glycerin is from about 40 to about 70 weight percent. 
     
     
         10 . A tissue sheet containing from about 0.2 to about 20 dry weight percent, based on the dry weight of the tissue sheet, of a topically applied softening composition, said softening composition comprising, based on the total amount of actives in the composition, from about 5 to about 50 weight percent polysiloxane, from about 10 to about 50 weight percent of a fatty alkyl derivative and from about 20 to about 80 weight percent glycerin. 
     
     
         11 . The tissue sheet of  claim 10  wherein the amount of the softening composition is from about 0.5 to about 5 dry weight percent. 
     
     
         12 . The tissue sheet of  claim 10  wherein the amount of the softening composition is from about 1 to about 2 dry weight percent. 
     
     
         13 . The tissue sheet of  claim 10  having a Wet Out Time of about 20 seconds or less. 
     
     
         14 . The tissue sheet of  claim 10  having a Wet Out Time of from about 3 to about 15 seconds. 
     
     
         15 . The tissue sheet of  claim 10  having a Wet Out Time of from about 3 to about 10 seconds. 
     
     
         16 . The tissue sheet of  claim 10  wherein the amount of the softening composition is from about 1 to about 2 dry weight percent, wherein the amount of polysiloxane in the softening composition is from about 5 to about 20 weight percent, the amount of fatty alkyl derivative in the softening composition is from about 30 to about 50 weight percent and the amount of glycerin in the softening composition is from about 40 to about 70 weight percent, said tissue sheet having a Wet Out Time of from about 3 to about 10 seconds. 
     
     
         17 . The tissue sheet of  claim 16  having a geometric mean tensile strength of from about 600 to about 1200 grams per 3 inches. 
     
     
         18 . The tissue sheet of  claim 16  having a geometric mean tensile strength of from about 700 to about 1000 grams per 3 inches. 
     
     
         19 . The tissue sheet of  claim 16  having a geometric mean tensile strength of from about 700 to about 900 grams per 3 inches. 
     
     
         20 . A tissue sheet containing a topically applied softening composition, said softening composition comprising, on a weight percent basis, from about 20 to about 30 weight percent polysiloxane and from about from about 20 to about 40 weight percent glycerin. 
     
     
         21 . The tissue sheet of  claim 20  wherein the weight ratio of polysiloxane:glycerin is from about 0.5 to about 1.4.
