Odor control composition and method of using
A chemical composition for controlling odor and to a method of using the chemical composition to impart an odor control treatment to an article, more particularly to a textile material or a building or construction material. The chemical composition comprises a metal compound selected from the group consisting of a metal oxide, a metal hydroxide, and a combination thereof and a sulfo polyester. Methods of making and of using are provided.
1 . An odor control composition for application and treatment of a textile material that maintains color-fastness of the textile material during and post application thereto, the odor control composition comprising:
zinc oxide,
a sulfo polyester, and
a pH adjuster,
wherein:
the odor control composition is an aqueous dispersion,
the odor control composition comprises from 97 wt % to 99 wt % water, and
the zinc oxide to sulfo polyester is present in a weight ratio of 10:1 to 2:1.
2 . The odor control composition according to claim 1 , wherein zinc oxide is present in a range of 0.01 weight % to 3 weight % based on weight of a textile material.
3 . The odor control composition according to claim 2 , wherein zinc oxide is present in a range of 0.1 weight % to 2 weight % based on weight of the textile material.
4 . The odor control composition according to claim 3 , wherein zinc oxide is present in a range of 0.15 weight % to 1.5 weight % based on weight of the textile material.
5 . The odor control composition according to claim 1 , wherein the sulfo polyester is prepared by polymerization of a dicarboxylic acid, diol, and a sulfo monomer.
6 . The odor control composition according to claim 5 , wherein the dicarboxylic acid is selected from the group consisting of isophthalic acid, terephthalic acid, cyclohexanediacetic acid, succinic acid, adipic acid, maleic acid, glutaric acid, and a combination thereof.
7 . The odor control composition according to claim 5 , wherein the diol is selected from the group consisting of diethylene glycol, polyethene glycol, butane diol, hexane diol, pentane diol, cyclohexanedimethanol, and a combination thereof.
8 . The odor control composition according to claim 5 , wherein the sulfo monomer is a difunctional sulfo monomer.
