On December 16, 2010, Batchelor, Stephen Norman; Bird, Jayne Michelle; Chen, Wei; Tao, Qingsheng; Wang, Jinfang published a patent.Name: 3-Amino-7-(diethylamino)-5-phenylphenazin-5-ium chloride The title of the patent was Cationic dye polymers. And the patent contained the following:
Disclosed is a detergent composition comprising from 2 to 70 weight-% of a surfactant together with from 0.0001 to 50 weight-% of a dye-polymer of mol. weight of at least 500, wherein the dye-polymer is obtainable by polymerization of: (a) a dye monomer, the dye monomer being an alkene covalently bound to a cationic charged dye, the dye monomer having a molar extinction coefficient at a wavelength in the range 400 to 700 nm of at least 1000 mol-1Lcm-1, preferably greater than 4000 mol-1Lcm-1, and (b) one or more further alkene comonomer(s), the alkene monomer(s) having a molar extinction coefficient at a wavelength in the range 400 to 700 nm, which is less than 100 mol-1Lcm-1, preferably less than 10 mol-1Lcm-1, wherein the dye monomer is cationically charged in an aqueous solution at a pH in the range from 7 to 11. Thus, a dye monomer was prepared by the reaction of methylene violet 3 RAX and acryloyl chloride in the presence of sodium dicarbonate, the resulting dye monomer was polymerized via radical polymerization with di-Me aminoethyl methacrylate, to obtained the dye polymer, which was tested for dye deposition, the polymer was added to give 5 ppm in a wash solution, containing 15% linear alkyl benzenesulfonate (LAS) surfactant, 30% Na2CO3, 40% NaCl, remainder minors included calcite and fluorescer, the fabrics washed were; polyester (microfiber), nylon-elastane (80:20) and cotton fabric, results showed that the dye-polymer deposits to the fabrics, an added advantage is that the dye-polymer also facilitates soil removal and alter fabric feel. The experimental process involved the reaction of 3-Amino-7-(diethylamino)-5-phenylphenazin-5-ium chloride(cas: 4569-86-2).Name: 3-Amino-7-(diethylamino)-5-phenylphenazin-5-ium chloride
The Article related to cationic azine dye polymer laundry detergent treatment washing textile, basic violet blue derivative cationic dye polymer fabric detergent, Surface Active Agents and Detergents: Dry-Cleaning Solvents and Laundering Detergents (Cleaning Of Finished Garments) and other aspects.Name: 3-Amino-7-(diethylamino)-5-phenylphenazin-5-ium chloride
