Abstract
A composition comprising a non-cationic amine epoxide adduct is disclosed, along with methods of making the same. Use of a composition comprising a non-cationic amine epoxide adduct on textiles and paper, particularly woven textiles, tissues, and nonwoven textiles to soften the textiles and paper, along with methods of using a non-cationic amine epoxide adduct to treat a target, are also disclosed.
Claims20
1:
- A softened paper product comprising:
- an amine epoxide adduct compound according to the formula:
- wherein R is an alkyl group or a —(CH2)n O-alkyl, and wherein n is an integer of between 1-1000;
- a paper;
- and
- wherein the softened paper product is free of quaternary ammonium compounds.
3 more elements
2:
- The softened paper product of claim 1, wherein the amine epoxide adduct is a compound according to the following formulas:
- or a combination thereof.
3:
- The softened paper product of claim 1, wherein the paper is formed from a pulp.
4:
- The softened paper product of claim 3, wherein the pulp comprises eucalyptus, softwood, cellulose fibers, wood fibers, or a combination thereof.
5:
- The softened paper product of claim 1, wherein the softened paper product is a facial tissue, a toilet tissue, napkin, or paper towel.
6:
- The softened paper product of claim 1, wherein the amine epoxide adduct increases bulk softness of the paper without substantial tensile strength loss.
7:
- The softened paper product of claim 1, wherein the paper is re-usable.
8:
- The softened paper product of claim 1, wherein the paper is disposable.
9:
- The softened paper product of claim 1, wherein the paper is comprised of silk fibers, linen fibers, cotton fibers, hemp fibers, angora fibers, bamboo fibers, polyester fibers, polyamide fibers such as nylon, acrylic fibers, acetate fibers, wool, rayon, cashmere, satin, spandex, cotton, polyester, or a combination thereof.
10:
- The softened paper product of claim 1, wherein the amine is pentaethylenehexamine, triethylenetetramine, tetraethylenepentamine, diethylenetriamine, hexaethyleneheptamine, or a combination thereof;
- or wherein the epoxide is 1,2-epoxydodecane, 1,2-epoxytetradecane, 1,2-epoxyhexadecane, 1,2-epoxyoctadecane, a C8-C10 alkyl glycidyl ether, a C12-C14 alkyl glycidyl ether, or a combination thereof.
11:
- The softened paper product of claim 1, wherein the softened paper product comprises from about 10 wt. % to about 80 wt. % of the amine epoxide adduct compound.
12:
- The softened paper product of claim 1, wherein the amine epoxide adduct is a multiple charged cationic compound having 1, 2, 3, or more positive charges or a multiple charged anionic compound having 1, 2, 3, or more negative charges.
13:
- The softened paper product of claim 1, wherein the softened paper product further comprises a processing aid comprising a non-deliquescent material.
14:
- The softened paper product of claim 1, wherein the amine epoxide adduct compound comprises a molar ratio of the epoxide to the amine between about 1:20 to about 20:1.
15:
- A method of softening a paper product comprising:
- contacting a first reagent comprising an amine and a second reagent comprising an epoxide to generate an amine epoxide adduct compound according to the formula:
- wherein R is an alkyl group or a —(CH2)n O-alkyl, and wherein n is an integer of between 1-1000;
- forming a mixture comprising the amine epoxide adduct compound;
- wherein the mixture is free of quaternary ammonium compounds;
- and
- contacting the mixture with the paper product.
4 more elements
16:
- The method of claim 15, wherein the amine is pentaethylenehexamine, triethylenetetramine, tetraethylenepentamine, diethylenetriamine, hexaethyleneheptamine, or a combination thereof;
- or wherein the epoxide is 1,2-epoxydodecane, 1,2-epoxytetradecane, 1,2-epoxyhexadecane, 1,2-epoxyoctadecane, a C8-C10 alkyl glycidyl ether, a C12-C14 alkyl glycidyl ether, or a combination thereof.
17:
- The method of claim 15, wherein the paper product is formed from a pulp.
18:
- The method of claim 17, wherein the pulp comprises eucalyptus, softwood, cellulose fibers, wood fibers, or a combination thereof.
19:
- The method of claim 15, wherein the paper product is a facial tissue, a toilet tissue, napkin, or paper towel.
20:
- The method of claim 15, wherein the amine epoxide adduct increases bulk softness of the paper without substantial tensile strength loss.
