The present invention relates to a recycling process for a laminate and a solution used in such a process. The present invention finds particular application in the removal of an adhered overlay from an underlying substrate material such as plastic. The process includes subjecting the laminate to an impact frictional striking force, thereby substantially separating the substrate layer from the one or more surface layers of the overlay and then washing the substrate layer with a washing solution to remove the remaining surface layers of the overlay and glue from the substrate layer. The washing solution may be an aqueous solution including a surfactant, a solvent and a base.

The present invention provides a biodegradable formulation and its use as a surfaces restoring agent, said formulation allows a substantial savings when restoring the existing paint on different surfaces, since it mainly cleans and restores the surface or paint contaminated by the environment, damaged due to the sun and the processes of the different industries, in addition to being friendly to the environment, making it a useful technology in any industrial branch that involves cleaning and restoring large areas. It is worth noting that the modifications to the original formula were made to optimize the results in the different applications and improve its biodegradability.

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 transfer to co-washed fabrics, but also reduced dye fading during laundering is met by formulating the detergent composition with a combination of a branched nonionic surfactant and a dye transfer inhibition (DTI) polymer.

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.

In a substrate processing method, a rinse process using a rinse solution is performed on a development-processed photoresist pattern on a substrate. A substitution process including a first substitution step using a mixed solution of a non-polar organic solvent and a surfactant and a second substitution step using the non-polar organic solvent is performed on the substrate. The substitution process is performed a plurality of times until the rinse solution remaining on the substrate is less than a predetermined value. A supercritical fluid drying process is performed on the substrate to dry the non-polar organic solvent remaining on the substrate.
