Provided are a cleaning agent and a preparation method and the use thereof. The cleaning agent is prepared from the following raw materials comprising the following mass fraction of components: 0.5%-20% of an oxidant containing iodine, 0.5%-20% of an etchant containing boron, 1%-50% of a pyrrolidinone solvent, 1%-20% of a corrosion inhibitor, 0.01%-5% of a metal ion-free surfactant, and water, with the sum of the mass fraction of each component being 100%, the pH of the cleaning agent is 7.5-13.5, and the corrosion inhibitor is one or more of a benzotriazole corrosion inhibitor, a hydrazone corrosion inhibitor, a carbazone corrosion inhibitor and a thiocarbohydrazone corrosion inhibitor. The cleaning agent can efficiently remove nitrides from hard mask residues with little effects on metals and low-κ dielectric materials, and has a good selectivity.

The present application relates to the technical field of daily cleaning and washing products, and particularly to a double layer detergent tablet and a preparation method thereof. The double layer detergent tablet includes a color absorbing fiber and a solid detergent adhered to the color absorbing fiber, the solid detergent includes the following components by mass percentage: 8-30% of polyvinyl alcohol, 10-40% of surfactant, 0.5-5% of polyvinylpyrrolidone, 1-5% of glycerin, 0.5-5% of water softener, 0.1-1% of plant essence, 14-79.9% of deionized water. The surfactant is a mixture of an anionic surfactant and a non-ionic surfactant; the anionic surfactant is a mixture of sodium coco-sulfate and sodium alpha-olefin sulfonate; and the non-ionic surfactant is a mixture of alkyl glycoside, fatty alcohol polyoxyethylene ether, isomeric alcohol polyoxyethylene ether and fatty acid methyl ester ethoxy compound.

A fluid washing composition with four separate components and laundry washing kit thereof is disclosed. The four components are housed in respective independent tanks of a laundry washing machine equipped with a program for selecting, dosing and differentiated delivering. Component 1 is a detergent formulation with a pH of 4.0-12.0, with high detergent effect in washing programs at temperatures of 40°-60° C., having a specific action on cotton fibers, particularly, whites. Component 2 is a detergent formulation with a pH of 8.0-12.0, with high detergent effect in washing programs at temperatures of 15°-40° C., having a specific action on synthetic, colored and animal-origin fibers. Component 3 is an enzyme-based stain-removing formulation including protease and lipase and possibly amylase with a pH of 5.0-6.0, stabilized with sorbitol and calcium chloride. Component 4 is an after-wash conditioning formulation, with a pH of 2.0-4.0.

The need for a detergent composition which provides reduced dye bleeding from fabrics, is met by formulating the composition using a combination of branched nonionic surfactant and cationic polymer.

A composition for removing a cosmetic material from a substrate includes glycerin ethoxylate and linear alkyl benzene sulfonate (LABS). An application of the composition to a stain including a deposit of a cosmetic material at a white polyester-cotton blend fabric to provide a stained polyester-cotton blend fabric exhibits an increased stain removal measured as reflectance observed at 460 nm by at least about 35% compared to a reflectance observed at the stained polyester-cotton blend fabric prior to the application. A treatment including the composition applied to the stained polyester-cotton blend fabric provides a reflectance at the stained polyester-cotton blend fabric that is greater than a reflectance observed at a white polyester-cotton blend fabric stained with a deposit of a cosmetic material and that has been treated with either the glycerin ethoxylate alone or that has been treated with the linear alkyl benzene sulfonate alone.
