Abstract
A softening composition for treating tissue products is disclosed. The softening composition comprises a combination of particular amino-functional polysiloxanes and alkoxylated alcohols in particular proportionate amounts. When applied to tissue products at add-on levels of less than about 5% by weight, the softening composition has been found not only to improve the softness of the product but also not to substantially interfere with the wettability characteristics of the sheet.
Claims32
A tissue product comprising:
- at least one tissue web containing pulp fibers, the tissue product having a first side and a second side;
- a softening composition applied to at least one side of the tissue product, the softening composition comprising from about 5% to about 30% by weight of an amino-functional polysiloxane having the following structure:
- wherein,
- m is 10 to 100,000;
- n is 1 to 5,000;
- G1 is R8 or R10—[X—R11]s—Y—R12;
- G2 are independently R9, a hydroxyl radical, an alkoxyl radical, or
- R10—[X—R11]s—Y—R12;
- R1 through R9 are independently selected from the group consisting of C1 to C8 substituted or unsubstituted, aliphatic or aromatic alkyl radicals;
- R10 and R11 are independently a substituted or unsubstituted C2 to C6 alkylene diradical;
- X and Y are independently a NR13 diradical;
- R12 and R13 are independently a hydrogen or a substituted or unsubstituted C1 to C20 alkyl radical;
- and
- S is 0 or 1;
- and from about 70% to about 95% by weight of a chemical having the following structure:
- R14—O—[C2H4O]d—[C3H6O]eR15
- wherein,
- R14 is a saturated or unsaturated, substituted or unsubstituted, primary or secondary straight chain or branched or cyclic C6 to C40 alkyl radical;
- R15 is a hydrogen radical or a C1 to C6 alkyl radical;
- d is 5 to 40;
- and
- e is 0 to 20;
- and wherein the softening composition is applied to the tissue product in a manner and in an amount such that the tissue product has a wet-out time of less than about 8 seconds.

- and from about 70% to about 95% by weight of a chemical having the following structure:
- R14—O—[C2H4O]d—[C3H6O]eR15
- wherein,
- R14 is a saturated or unsaturated, substituted or unsubstituted, primary or secondary straight chain or branched or cyclic C6 to C40 alkyl radical;
- R15 is a hydrogen radical or a C1 to C6 alkyl radical;
- d is 5 to 40;
- and
- e is 0 to 20;
- and wherein the softening composition is applied to the tissue sheet in a manner and in an amount such that the tissue sheet has a wet-out time of less than about 8 seconds.
19 more elements
A tissue product comprising:
- at least one tissue web containing pulp fibers, the tissue product having a first side and second side;
- a softening composition applied to the first side and to the second side of the tissue product, the softening composition covering from about 40% to about 99.9% of the surface area of each side of the tissue product, the softening composition being applied to the tissue product so as to have a total solids add-on of from about 0.5% to about 5% by weight, the softening composition comprising from about 5% to about 30% by weight of a hydrophilically-modified amino-functional polysiloxane and from about 70% to about 95% by weight of an alkoxylated alcohol;
