Amine copolymers for textile and fabric protection
View Patent ↗The present invention relates to a detergent composition having from 3 to 75 percent by weight of at least one surfactant; and from 0.01 to 5 percent by weight percent of a copolymer composed of from about 70 to 100 mole percent of at least one amine-functional monomer, and from about 30 to 0 mole percent of at least one hydrophobic ethylenically unsaturated monomer, wherein said amine-functional monomer is not a quaternized amine, and wherein said copolymer has been at least partially neutralized. The detergent composition having the copolymers provides color protection and anti-pill properties in laundry applications.
1. A detergent composition comprising:
from 3 to 75 percent by weight of at least one anionic or nonionic surfactant; and
from 0.01 to 5 percent by weight of a copolymer having
from 80 to 100 mole percent of at least one amine-functional monomer;
from 0 to 30 mole percent of at least one hydrophobic ethylenically unsaturated monomer;
from 0 to 30 mole percent of an hydroxy functional ethylenically unsaturated monomer; and
from 0 to 10 mole percent of a diethylenically unsaturated monomer or polyfunctional mercaptan;
wherein said amine-functional monomer is not a quaternized amine, and
wherein said copolymer has been at least 75 mol % neutralized with an organic acid.
2. The copolymer of claim 1 wherein said amine functional monomer is selected from the group consisting of N,N-dialkylaminoalkylmethacrylate, N,N-dialkylaminoalkylacrylate, dialkylaminoalkylmethacrylamide, and N,N-dialkylaminoalkylacrylamide, where the alkyl groups are independently C 1-18 and combinations thereof.
3. The copolymer of claim 1 wherein said amine functional monomer is selected from the group consisting of N,N-dimethylaminoethylmethacrylate, N,N-dimethylaminopropylacrylamide and combinations thereof.
4. The copolymer of claim 1 wherein said hydrophobic ethylenically unsaturated monomer is selected from the group consisting of (meth)acrylates, maleates, (meth)acrylamides, vinyl esters, itaconates, styrenics, unsaturated hydrocarbons and acrylonitrile, nitrogen functional monomers, vinyl esters, alcohol functional monomers, unsaturated hydrocarbons, and C 8 -C 22 alkoxylated (meth)acrylates and mixtures thereof.
5. The detergent composition of claim 1 comprising from 0.1 to 2.0 weight percent of said copolymer.
6. The detergent composition of claim 1 wherein the organic acid comprises citric acid, glycolic acid, oxalic acid, lactic acid or combinations thereof.
7. The copolymer of claim 1 further comprising from 0 to 30 mole percent of an acid functional monomer.
8. The copolymer of claim 1 further comprising from 0 to 30 mole percent of an hydroxyalkyl or aromatic capped poly(alkoxylated) monomer.
9. A fibrous material comprising:
a woven or knit natural fibrous substrate; and
a protective coating having a copolymer having
from 80 to 100 mole percent of at least one amine-functional monomer;
from 0 to 30 mole percent of at least one hydrophobic ethylenically unsaturated monomer,
from 0 to 30 mole percent of an hydroxy functional ethylenically unsaturated monomer, and
from 0 to 10 mole percent of a diethylenically unsaturated monomer or polyfunctional mercaptan;
wherein said amine-functional monomer is not a quaternized amine, and wherein said copolymer is at least 75 mol % neutralized with an organic acid.
10. The fibrous material of claim 9 wherein said fibrous substrate is selected from the group consisting of textiles, woven fabrics, knit fabrics, and carpet.
11. The fibrous material of claim 9 wherein said copolymer further comprises from 0 to 20 mole percent of an acid functional monomer.
12. The fibrous material of claim 9 wherein said copolymer further comprises from 0 to 10 mole percent of a hydroxy, alkyl or aromatic capped poly(alkoxylated) monomer.
13. The fibrous material of claim 11 wherein said protective coating improves color retention of fibrous material when compared to fibrous material without the protective coating.
